710 Advanced echocardiographic analysis to identify cardiac toxicity after TKI exposure in patients with CML

Abstract Aims Worsening of cardiac function with increased arrhythmic risk is common in cancer patients undergoing chemotherapy. Impaired LV global longitudinal strain (GLS) in these patients despite preserved ejection fraction is a common issue. Recently, myocardial work by speckle-tracking echocardiography has been used to overcome GLS limitations in various conditions, but little is known about its usefulness in the detection of cardiac toxicity. Moreover, left atrial (LA) toxicity may occur early in the course of cancer therapy. The main aim of the study was to assess the cardiotoxic effects of tyrosine kinase inhibitors (TKIs) on patients with Philadelphia chromosome-positive chronic myeloid leukaemia (Ph+ CML) by using novel echocardiographic tools as myocardial work and atrial strain analysis. Methods and results We retrospectively enrolled Ph+ CML patients treated with TKIs followed at the cardio-oncology outpatient clinic of our hospital from December 2018 to March 2019 who underwent clinical evaluation with ECG and echocardiogram (TTE) before and after 1 year of treatment with TKIs. Healthy subjects were enrolled in the control group matched for gender, age and cardiovascular risk factors. Myocardial work was derived from the strain-pressure relation, integrating in its calculation the non-invasive arterial pressure. LA longitudinal strain (reservoir, conduit, and booster) was obtained from an optimized apical 4-chamber view of the LA. The study recruited 32 patients in Ph+ CML group and 32 healthy controls. 39% of patients were treated with Imatinib, 29.3% with Nilotinib, 4.9% with Dasatinib and 4.9% with Ponatinib. Main results are detailed in Table 1. At 1-year follow-up there was a significant reduction compared to baseline in global constructive work (2555.22 ± 564.33 vs. 2119.31 ± 700.19; P = 0.0001), global work efficiency (96.13 ± 1.90 vs. 94.00 ± 2.96; P = 0.002), and global work index (2340.75 ± 579.57 vs. 1938.46 ± 680.23; P = 0.001), and a non-significant reduction in global wasted work (P = 0.393). Regarding left atrial strain analysis at the 1-year follow-up there was a statistically significant reduction in LA contractile strain (booster= 14.63 ± 1.408 vs. 12.38 ± 1.581; P = 0.018). LA contractile strain reduction was also observed in the comparison with controls (12.38 ± 2.99 vs. 14.91 ± 3.09; P = 0.009). Any other significant difference was detected between baseline and FU TTE data in the Ph+ CML group. Conclusions New imaging methods for the study of cardiotoxicity provide an additional tool for early prediction of potential adverse effects of antineoplastic drugs. TKIs therapy leads to an impairment of atrial contractility, which can be detected by atrial strain e myocardial work analysis.

Abstract Aims Patients affected by Philadelphia chromosome+ chronic myeloid leukaemia (Ph+CML) undergoing to therapy with tyrosine kinase inhibitors (TKIs) are prone to develop cardiovascular complications, which have relevant prognostic implications. Speckle-tracking echocardiography, allowing strain and myocardial work analyses, can be useful in the early detection of cardiac toxicity. Aim of our study was to assess the cardiotoxic effects of TKIs. Methods We evaluated, at baseline and during FU, 20 patients affected by Ph+ CML (59.7 ± 12.2 years, 13 males), treated Imatinib (52.6%), Nilotinib (36.8%), Ponatinib (5.3%), Dasatinib (5.3%). We measured systolic and diastolic blood pressure (SBP-DBP) and calculated corrected QT interval (QTc). In addition, we analysed echocardiographic parameters including left ventricular ejection fraction (LVEF), global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE), and peak left atrial longitudinal strain (PALS). Cardiovascular (CV) events that we considered were symptomatic or asymptomatic LV dysfunction, acute coronary syndrome (ACS), peripheral artery disease (PAD), and arrhythmias. Results Follow-up (FU) time was 3.4 ± 1 years. Most of patients (63.2%) had cardiovascular risk factors, including arterial hypertension (50%), type2 diabetes mellitus (15%), dyslipidaemia (40%) and cigarette smoking (15%). At the end of FU, SBP was unchanged (128.9 ± 19.6 mmHg vs. 129.1 ± 9.8 mmHg; P=NS) whereas DBP increased (69.4 ± 8.5 mmHg vs. 75 ± 7.7 mmHg; P = 0.004); moreover QTc was longer than baseline (404.4 ± 20.1 ms vs. 424.3 ± 29.8 ms; P < 0.001) and LVEF showed a significant decrease (62.2 ± 3.9% at baseline vs. 59.3 ± 4.8% at FU; P = 0.003); similarly, GCW (2444.1 ± 540mmHg% vs. 2234.7 ± 179.4 mmHg%; P = 0.034), GWI (2158.1 ± 589.6 mmHg% vs. 1923.1 ± 174.5 mmHg%; P = 0.022) and PALS (36.3 ± 17.1% vs. 32.8 ± 9.7%; P = 0.002) decreased during cancer therapy. On the other hand, GLS (−18.6 ± 3.1% vs. −19.4 ± 1.1%; P=NS), GWE (94.3 ± 4.1% vs. 93.6 ± 3.6%; P=NS) and GWW (120.6 ± 94.3 mmHg% vs. 106.3 ± 68.9 mmHg%; P=NS) did not change significantly. CV events were observed in 66.7% of the study population. These were mostly represented by ACS, atrial arrhythmias and symptomatic LV dysfunction (30.7% for each) and, to a lesser extent, PAD (7.6%). By comparing patients with events (group A) with those without events (group B) we found that differently from group B, group A showed during FU a significant increase of DBP (from 66 ± 5.2 mmHg to 71.2 ± 6.1 mmHg, P = 0.010; vs. group B= from 76 ± 12.mmHg to 78 ± 4.1 mmHg, P=NS) and a significant QTc prolongation (from 415.7 ± 16.1 ms to 441 ± 29.8 ms, P < 0.001; vs. group B= from 390.4 ± 19.3 ms to 405.6 ± 23.3 ms, P=NS); as to echocardiographic parameters, we found, in patients with CV events, a significant decrease of: LVEF (from 62.7 ± 4.7% to 58.8 ± 4.3%, P = 0.004; vs. group B from 61.4 ± 2.8% to 60 ± 1.7%, P=NS), GCW (from 2566.2 ± 669.6 mmHg% to 2230.1 ± 199.4 mmHg%, P = 0.021, vs. group B 2194 ± 167.5 mmHg% to 2212.6 ± 160mmHg%, P=NS) and PALS (from 36.1 ± 17% to 29.6 ± 6.6%, P = 0.022 vs. group B from 32.7 ± 8% to 35 ± 8.5%, P = 0.003). Of these parameters, only PALS was significant independent predictor of CV events on logistic regression analysis (OR 0.82 CI 95 0.69–0.98, P = 0.034). Conclusions Advanced echocardiographic parameters, including myocardial work and left atrial strain analysis, are particularly valuable in the early detection of TKI-induced cardiac toxicity. PALS could be an useful tool to predict outcome in these patients.

Our aim was to compare the global longitudinal and regional biventricular strain between infants with severe and critical pulmonary stenosis (PS), and controls; to compare pre- and post-procedural strain values in infants with severe and critical PS; and to assess the correlations between echocardiographic strain and conventional parameters. We conducted a retrospective single-center study. The comparisons of echocardiographic variables were performed using separate linear mixed models. The overall mean right ventricle (RV) regional strains measured before intervention in PS patients was significantly different when compared to the control group (p = 0.0324). We found a significant change in the left ventricle, RV, and inter-ventricular septum strain (IVS) values from basal to apical location (p < 0.05). IVS strain values showed a higher decrease in mean strain values from basal to apical in PS patients. There was no significant difference in means of baseline and post-interventional strain values in PS patients (p > 0.05). Following the strain analysis in patients with PS, we obtained statistically significant changes in the RV global-4-chamber longitudinal strain (RV4C). The RV4C, which quantifies the longitudinal strain to the entire RV, can be used in current clinical practice for the evaluation of RV function in infants with severe and critical PS. The longitudinal and segmental strain capture the pathological changes in the IVS, modifications that cannot be highlighted through a classical echocardiographic evaluation.

: We aimed to explore left atrial (LA) remodeling in the patients with solid cancer before initiation of chemo- or radiotherapy. This retrospective investigation included 92 chemo- and radiotherapy-naive cancer patients and 40 age- and gender-matched controls with a similar cardiovascular risk profile as the cancer group. All participants underwent comprehensive echocardiographic examination before the start of chemo- or radiotherapy. LA phasic function was evaluated in volumetric and strain method. Indexed minimal and pre-A LA volumes were significantly higher in the cancer patients. Total and passive LA emptying fraction (EF) were significantly lower, whereas active LAEF was significantly higher in the cancer patients. LA total longitudinal strain was significantly lower in the cancer patients. Strain rate analysis of LA phasic function showed that LA function during systole and early diastole was reduced in the cancer group, while it was increased during late diastole. These findings indicated that LA reservoir and conduit functions, assessed with LA volumetric and strain analysis, were deteriorated in the cancer group. On the other hand, LA booster pump function was elevated in the cancer group in comparison with the controls. In the whole population, cancer was associated with reduced LA total longitudinal strain independently of age, gender, BMI, LV hypertrophy, E/e’ ratio, diabetes, and hypertension. LA phasic function was impaired in the chemo- and radiotherapy-naive cancer patients in comparison with the control group. Cancer, LV hypertrophy, and hypertension were associated with reduced LA longitudinal strain independently of other important clinical parameters.

Background: The aim of this aortic stenosis registry was to investigate the changes of routine echocardiographic indices and strain in patients with moderate-to-severe aortic stenosis over a 6-month follow-up period. Methods: Our aortic stenosis registry is observational, prospective, multicenter registry of nine countries, with 197 patients with aortic valve area less than 1.5 cm2. The enrolment took place from January to August 2017. We excluded patients with uncontrolled atrial arrhythmias, pulmonary hypertension or cardiomyopathies, as well as those with hemodynamically significant valvular disease other than aortic stenosis. We included patients who did not require intervention and who had a complete follow-up study. Results: In patients with preserved ejection fraction, left ventricular mass has significantly increased between baseline and follow-up studies (218 ± 34 grams vs 253 ± 29 grams, p = 0.02). However, when indexed to body surface area, there was no significant difference. Left ventricular global longitudinal strain significantly decreased (-19.7 ± -4.8 vs (-16.4 vs -3.8, p = 0.01). Left atrial volume was significantly higher at follow-up (p = 0.035). Right ventricular basal diameter and mid-cavity diameter were greater at the follow-up (p = 0.04 and p = 0.035, respectively). Patients with low-flow low-gradient aortic stenosis had significantly lower global longitudinal strain (-12.3% ± -3.9% vs -19.7% ± -4.8%, p = 0.01). Conclusion: Left atrial dilatation is one of the first changes to take place in low-flow low-gradient aortic stenosis patients even when left ventricular dimensions and function remains intact. Global longitudinal strain is an important determinant of left ventricular systolic and diastolic dysfunction and right ventricular function is an important parameter of aortic stenosis assessment. Accordingly, our registry has further shed the light on these indices role as multisite follow-up of aortic stenosis.

Although the efficacy of cardiac rehabilitation (CR) is proven, the need to improve patients’ adherence has emerged. There are only a few studies that have investigated the effect of sending text messages after a CR period to stimulate subjects’ ongoing engagement in regular physical activity (PA). A randomized controlled pilot trial was conducted after CR, sending a daily PA text message reminder to an intervention group (IG), which was compared with a usual care control group (CG) during three months of follow-up. Thirty-two subjects were assessed pre- and post-study intervention with GPAQ, submaximal iso-watt exercise testing, a 30 s sit-to-stand test, a bilateral arm curl test, and a final survey on a seven-point Likert scale. A statistically significant difference in the increase of moderate PA time (Δ 244.7 (95% CI 189.1, 300.4) minutes, p < 0.001) and in the reduction of sedentary behavior time (Δ −77.5 (95% CI 104.9, −50.1) minutes, p = 0.004) was shown when the IG was compared with the CG. This was associated with an improvement in heart rate, blood pressure, and patients’ Borg rating on the category ratio scale 10 (CR10) in iso-watt exercise testing (all p < 0.05). Furthermore, only the IG did not show a worsening of the strength parameters in the follow-up leading to a change of the 30 s sit-to-stand test with a difference of +2.2 (95% CI 1.23, 3.17) repetitions compared to CG (p = 0.03). The telemedical intervention has been appreciated by the IG, whose willingness to continue with regular PA emerged to be superior compared to the CG. Text messages are an effective and inexpensive adjuvant after phase 2 CR that improves adherence to regular PA. Further studies are needed to confirm these results in a larger patient population and in the long term.

Abstract Background Atrial fibrillation (AF) impairs mechanical function of the heart, especially atria and restoration of sinus rhythm (SR) leads to improvement of mechanics. The predicting role of changes in strain parameters for AF recurrence is not established yet. Purpose To analyse changes in left atrial (LA) and left ventricular (LV) mechanical function after conversion to SR and their prognostic values for AF recurrence during 24 months follow-up. Methods Prospective study involved 59 patients after successful electrical cardioversion (EC) because of nonvalvular AF (mean age 65±4 years, 47% female). Speckle tracking analysis (STE) was applied to calculate longitudinal strain of LV and LA before EC and within 24 hours after restoration of SR and additionally total left heart strain (TS) defined as a sum of absolute peak LV and LA strain. We calculated change in strain between AF and SR analyses expressed as delta (Δ). During follow-up we noticed AF recurrence in 42 (71%) patients, most of them (93%) during 1st year after EC. Median time of AF recurrence was 3 months. Results We noticed significant immediate post-EC improvement in peak LA longitudinal strain (PALS) and LV global longitudinal strain (LVGLS) (table). Unlike CHA2DS2-VASc score, strain parameters were predictors of AF recurrence. Every 1% increment in ΔLVGLS was related with 13% increase in AF recurrence risk (p=0.02) and every 1% increment in ΔPALS and ΔTS were related with 9% decrease in AF recurrence risk (p=0.007 and p=0.0014, respectively). Multivariate analysis revealed ΔTS as a strongest predictor with 9% decrease in AF risk per every 1% increment. The criterion of ΔTS ≤7.5% allows to predict AF recurrence with 81% sensitivity and 63% specificity. Conclusions Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR and these absolute changes in LVGLS as well as PALS can predict AF recurrence, with optimal stratification by novel parameter - TS.

Abstract Purpose To determine the impact of failed ab-interno trabeculectomy on the postoperative outcome of subsequent XEN45 gel stent (Allergan, CA, USA) implantation in pseudophakic eyes. Methods In this retrospective single-center study, we included 60 pseudophakic eyes from 60 participants who underwent XEN45 gel stent implantation. Thirty eyes each underwent primary stent implantation (control group) or had previously undergone a failed ab-interno trabeculectomy (trabectome group). The groups were matched at a 1:1 ratio based on the following criteria: preoperative and maximum Intraocular pressure (IOP), preoperative medication score, cup/disk-ratio, follow-up time, best-corrected visual acuity at baseline, age, and the proportion of patients classified as primary open angle glaucoma or exfoliation glaucoma. We defined a successful surgery by the following three scores: an IOP reduction > 20% and IOP at the longest follow-up < 21 mmHg (Score A) or < 18 mmHg (Score B) or IOP ≤ 15 mmHg and an IOP reduction ≥ 40% (Score C). One open conjunctival revision was allowed in all scores, and a repeat surgery was considered a failure. Results Following an average follow-up period of 22 ± 12 months, we observed a mean IOP reduction of 38%, from 23.5 ± 5.2–14.5 ± 5.0 mmHg. Comparative analyses between the groups did not reveal a significant difference in the postoperative IOP, postoperative medication score, side effects, revision rate, repeat surgery rate, or success rate. Conclusions Trabectome is a viable first-line procedure for medically uncontrolled glaucoma before filtering ab-interno microstent surgery is considered.

Abstract Introduction Early detection of affected family relatives of patients with dilated cardiomyopathy (DCM) is essential in order to guide follow up, outcomes and initiate early treatment. Myocardial work analysis is a novel method which integrated strain imaging and blood pressure and has the potential to identify patients with subclinical disease. Purpose We analysed myocardial work in family relatives of DCM patients with positive genotype but negative phenotype in order to identify whether myocardial work can identify early changes. Methods Seventy-four family relatives of DCM patients attending for screening were examined. All individuals were asymptomatic with either positive (45/74, G+) or negative (29/74, G-) genotype and no echocardiographic evidence of left ventricular dilatation or systolic impairment. Non-invasive myocardial work analysis using two-dimensional (2D) speckle tracking echocardiography was analysed. Global longitudinal strain (GLS) was measured by the same vendor specific software used for myocardial work analysis. Left ventricular (LV) ejection fraction (EF) was measured with the Simpson's biplane method. The peak systolic arm cuff blood pressure (BP) measurement at the time of echocardiography was used for the myocardial work study. Results In total we included 74 individuals (37±15 years old, 50.7% women) with mean systolic and diastolic BP of 121.3±14 and 73.2±10 mmHg respectively, mean EF was 58±5% and mean GLS at 18.4±2.5%. G+ individuals had pathogenic and very likely pathogenic mutations in 8 different genes (TTN, BAG3, DSP, FLNC, LMNA, DMD, RBM20, TPM1). There was no difference in age, systemic hypertension, diabetes or medical treatment between the 2 groups. No significant difference was found among G+ and G- individuals in mean systolic and diastolic BP (121.2±14.7 vs 121.2±15.2 mmHg), mean EF (57.3±5 vs 59.1±4%), GLS (−18.2±1.5 vs −18.6±2.9%), mean global work index (1818±403 vs 1928±295 mmHg%) and global constructive work (2192±464 vs 2260±318 mmHg%). However, we found significant reduction of the global work efficiency (GWE) with a GWE of 94.4±2.7% in the G+ versus 95.9±1.6% in the G- individuals (p 0.02). Moreover, the global wasted work (GWW) was increased in the G+ with a GWW of 111±58 mmHg% versus 82±41 mmHg% in the G- individuals (p 0.03). Conclusion DCM gene carriers show, early on, decreased myocardial work efficiency and increased wasted work compared to unaffected family members, which appears to be earlier than other parameters such as EF and GLS. Myocardial work analysis could potentially recognize individuals showing early cardiac involvement and guide closer follow up and early initiation of treatment.

Background: Hip capsular management after hip arthroscopy remains a topic of debate. Most available current literature is of poor quality and are retrospective or cohort studies. As of today, no clear consensus exists on capsular management after hip arthroscopy. Purpose: To evaluate the effect of routine capsular closure versus unrepaired capsulotomy after interportal capsulotomy measured with NRS pain and the Copenhagen Hip and Groin Outcome Score (HAGOS). Materials and methods: All eligible patients with femoroacetabular impingement who opt for hip arthroscopy ( n = 116) were randomly assigned to one of both treatment groups and were operated by a single surgeon. Postoperative pain was measured with the NRS score weekly the first 12 weeks after surgery. The HAGOS questionnaire was measured at 12 and 52 weeks postoperatively. Results: Baseline characteristics and operation details were comparable between treatment groups. Regarding the NRS pain no significant difference was found between groups at any point the first 12 weeks after surgery ( p = 0.67). Both groups significantly improved after surgery ( p < 0.001). After 3 months follow-up there were no differences between groups for the HAGOS questionnaire except for the domain sport ( p = 0.02) in favour of the control group. After 12 months follow-up there were no differences between both treatment groups on all HAGOS domains ( p > 0.05). Conclusions: The results of this randomised controlled trial show highest possible evidence that there is no reason for routinely capsular closure after interportal capsulotomy at the end of hip arthroscopy. Trial Registration: This trial was registered at the CCMO Dutch Trial Register: NL55669.048.15.
