Remote magnetic navigation (RMN) facilitates ventricular arrhythmia (VA) ablation. This study aimed to evaluate the long-term efficacy of RMN-guided ablation for ventricular tachycardia (VT) and premature ventricular contractions (PVC). A total of 176 consecutive patients (mean age 53.23 ± 17.55 years, 37% female) underwent VA ablation for PVC (132 patients, 75%) or VT (44 patients, 25%). The cohort consisted of 119 patients (68%) with idiopathic VA, 31 (18%) with ischemic (ICM), and 26 (15%) with dilated cardiomyopathy (DCM). VA recurrence was observed in 69 patients (39%, mean age 51.71 ± 19.91 years, 23% female) during a follow-up period of 5.48 years (first quartile 770.50 days, second quartile 1101.50 days, third quartile 1615.50 days). Left ventricular ejection fraction <40% lead to a significantly increased risk for VA (p = 0.031*). Multivariate analyses found DCM to be an independent predictor (IP) for VA recurrence (p < 0.001*, hazard ratio (HR) 3.74, confidence interval (CI) 1.58–8.88). ICM resulted in a lower increase in VA recurrence (p = 0.221, HR 1.49, CI 0.79–2.81). Class I/III/IV antiarrhythmic drug therapy (AADs) was also identified as IP for recurrence (p = 0.030*, HR 2.48, CI 1.11–5.68). A total of 16 patients (9%) died within the observational period. RMN-guided ablation of VA lead to acceptable long-term results. An impaired LV function, DCM, and AADs were associated with a significant risk for VA recurrence. Personalized paths are needed to improve efficacy and outcome.

Introduction: Preterm (PT) birth is associated with increased risk of cardiovascular diseases (CVD) and heart failure. We previously reported left ventricular (LV) mitochondrial dysfunction in a rat model mimicking the deleterious conditions associated with PT birth. Whether mitochondrial function is altered in humans born PT and associated with LV function changes is unknown. We aimed to determine if serum humanin levels, a mitochondrial-derived peptide with cytoprotective effects, are altered in humans born PT and are associated with impaired myocardial function. Methods: Data were obtained from 55 young adults born PT (<30 weeks of gestational age, GA) compared to 54 full-term (T) controls of the same age. Serum humanin levels were determined by ELISA and LV ejection fraction (LVEF) by echocardiography. Results are shown as median (interquartile range) and comparisons between groups were performed using non-parametric tests. Results: Individuals were evaluated at 23.3 (21.4, 25.3) years, and age and sex distribution were similar between groups. Median GA was 27.5 (26.2, 28.4) weeks in the PT group. Humanin levels (pg/ml) were 132.9 (105.1, 189.3) and 161.1 (123.6, 252) in the PT and the T groups, respectively (p=0.0414). LVEF was within the normal range and similar between groups. Lower LVEF was associated with lower humanin levels (p<0.001), and this association was observed both in the term (p=0.002) and the preterm (p=0.047) groups. Conclusions: Serum humanin levels are lower in adult born PT. Since lower humanin levels are also associated with lower LVEF, our results suggest that mitochondrial alterations could play a role in the long-term adverse cardiovascular consequences of PT birth. Humanin analogs improve LV function in experimental models. Our results pave the way for future studies exploring humanin as a therapeutic avenue for the prevention and treatment of CVD in individuals born PT.

The OBJECTIVE of the study was to analyze the experience of performing thyroidectomy (TE) in patients with amiodarone-induced thyrotoxicosis (AmIT) at our centre.METHODS AND MATERIALS. The study included 12 patients with AmIT who underwent TE. Medical records were analyzed to assess the features of the AmIT and indications for TE. We also studied the operation protocols and postoperative follow-up data. Intraoperative, early and long-term postoperative complications were recorded. The long-term TE results were evaluated by the dynamics of the left ventricular ejection fraction (LVEF) based on the echocardiography data.RESULTS. The main indications for TE included the resistance of thyrotoxicosis to medication and worsening of the cardiac pathology. No cases of thyrotoxicosis progression or thyrotoxic crisis were registered during the operation. The vocal cord paresis developed in one case, completely restored in a year. Blood loss was minimal in all cases. Other intraoperative complications were absent. Not a single death was registered in the early postoperative period. At this period, a short paroxysm of atrial fibrillation resolved on its own was registered in patient with arrhythmogenic right ventricular dysplasia. A patient with biventricular chronic heart failure of a high functional class died 39 days after the operation due to a massive pulmonary thromboembolism. The long-term results of TE were evaluated in eight patients. In four out of five patients with initially reduced LVEF, it increased. In three patients with initially normal LVEF, it did not change.CONCLUSION. Thyroidectomy is an effective and safe treatment in patients with AmIT, including those with the persistent thyrotoxicosis and severe cardiac pathology. The success is possible when the preparation of patients for the intervention is carried out by a team of specialists experienced in treating of such patients.

Aim: The aim of the study was to evaluate PCI and CABG long-term results in patients with multivessel disease during 8–10 years observation based on the CCS scale, vital status and left ventricular ejection fraction (LVEF). Materials and methods: The analysis involved 100 patients, who were randomized to SOS study (PCI-49; CABG-51) in 1997–2000 in the Silesian Heart Center, Katowice, Poland. There was no difference between both groups according to the basic demographic and angiographic data. The average time of observation was 8,4 ± 0,85 years. Echocardiography was performed four times in each patient: before and after the procedure, 3–4 years later and last time 8–10 years after the procedure. Stenocardia was assessed in accordance with the CCS classification. Results: During nearly 10 years follow-up there was 9 deaths in the PCI group (18%, 4 cardiac -8%) and 8 deaths in the CABG group (16%, 4 cardiac, 8%) (F-Cox-test: p=ns for all cause mortality and cardiac death). LVEF and intensification of stenocardia estimated based on CCS classification were not statistically different between both groups at the end of observation. However, in PCI group LVEF increased significantly (p=0,03), while in CABG group it was unchanged. In both groups improvement of symptoms after revascularization was maintained during the follow-up (Wilcoxon test: p<0.001) but it was achieved with repeat revascularization, which was more frequent in PCI group (30 vs 6%, p=0.003). Conclusions: Long-term results demonstrate that both methods of the myocardial revascularization are equal in terms of long-term survival, release of angina and preservation of left ventricular systolic function.

Abstract Background Takotsubo syndrome (TTS) is featured by an acute and reversible left ventricular dysfunction and can be complicated by cardiogenic shock. Intra-aortic balloon pumping (IABP) use in this setting is controversial, and few data are available from large populations. Aim of this study was therefore to evaluate short- and long-term impact of IABP on mortality in TTS complicated by cardiogenic shock. Methods The GEIST registry is a multicenter, international registry on TTS involving 38 centers from Germany, Italy and Spain. Between 2006 and 2017, 2250 consecutive patients with TTS were enrolled. Results Of the 2250 patients, 211 (9%) experienced cardiogenic shock during hospitalization for TTS. Admission left ventricular ejection fraction (LVEF) was 30±15% and systolic blood pressure was 90±35 mmHg. Apical ballooning pattern was found in 77%, mid-ventricular/basal pattern in 11%, and 2% of the patients, respectively. Forty-two patients out of 211 (19%) received IABP after coronary angiography. Patients receiving IABP compared to standard medical therapy did not differ in terms of age, gender, cardiovascular risk factors and admission LVEF. No differences were found in term of in-hospital mortality (9.5% vs 17% p=0.35), length of hospitalization (19.3 vs 16.3 days p=0.34), need of invasive ventilation (35% vs 41% p=0.60), stroke (4.7% vs 11% p=0.17) and LV thrombus (0.5% vs 1.7%, p=0.98). At long-term follow-up, with a median of 2 years, overall mortality in patients with cardiogenic shock and TTS was 34.1%. Mortality was not different between the IABP and the control group (33.7% vs 35.0%; p=0.85). Conclusions In this large multicenter observational registry, the use of IABP has no impact on mortality at short and long-term follow-up. Further studies are needed to evaluate the best therapeutic strategy in TTS complicated by cardiogenic shock.

Long-term right ventricular pacing (RVP) is associated with more cardiovascular death, atrial fibrillation (AF), thromboembolic complications and heart failure(HF). RVP often results in prolonged QRS duration(QRSd) and ventricular desynchronization. The ventricular desynchronization as a result of RVP leads to an increased risk of heart failure hospitalization (HFH) and AF, and this effect is dependent on cumulative percent ventricular paced ( % VP). In the sub-study from the MOST trial, it was evident that % VP >40% was associated with a 2.6-fold increased risk of HFH compared with pacing < 40% of the time despite preserved atrioventricular synchrony. Moreover this adverse effect of RVP induced ventricular desynchrony was more pronounced in patients with left ventricular ejection fraction( LVEF) of 40% or less resulting in increased death or HFH.

The aim of this retrospective multicenter registry study was to investigate age-dependent trends in mortality, long-term survival, and comorbidity over time in patients who underwent isolated CABG from 2003 to 2015. The percentage of patients < 60 years of age was 18.9%. Female sex, chronic pulmonary disease, extracardiac arteriopathy, and neurologic dysfunction disease were significantly less frequent in this younger population. The prevalence of BMI ≥ 30, previous myocardial infarction, preoperative severe depressed left ventricular ejection fraction, and history of previous PCI were significantly higher in this population. After PS matching, at 5 years, patients < 60 years of age reported significantly lower overall mortality (p<0.0001), cardiac-related mortality (p<0.0001), incidence of acute myocardial infarction (p=0.01), and stroke rates (p<0.0001). Patients < 60 years required repeated revascularization more frequently than older patients (p=0.05). Patients < 60 who underwent CABG had a lower risk of adverse outcomes than older patients. Patients < 60 have a different clinical pattern of presentation of CAD in comparison with more elderly patients. These issues require focused attention in order to design and improve preventive strategies aiming to reduce the impact of specific cardiovascular risk factors for younger patients, such as diet, lifestyle, and weight control.

629 Background: The use of trastuzumab is associated with an increased risk of cardiotoxic events such as congestive hearth failure (CHF) and decline in the left ventricular ejection fraction (LVEF). Our objectives were to evaluate the incidence of cardiac dysfunction, to identify risk factors and to evaluate the outcome of patients with MBC treated with trastuzumab for one year or longer. Methods: Among 218 MBC patients treated with trastuzumab-based therapy for at least one year, 173 patients were evaluable for cardiac toxicity. Cardiac events (CE) were defined as follows: 1) asymptomatic drop of LVEF below 50%; 2) drop of 20 percentage points in LVEF compared to the baseline; 3) signs or symptoms of CHF. The cardiac toxicity was graded according the NCI-CTCAE, version 3.0. Results: Median age at the start of trastuzumab therapy was 50 years (range, 26–79), median cumulative time on trastuzumab was 21.3 months (range, 11.6–77.6), and median follow-up was 32.2 months (range, 9.7–79.0). Eighty-five percent of patients received prior anthracyclines (median cumulative doxorubicin dose: 300 mg/m2). Forty-nine patients (28%) experienced a CE: 3 patients (1.7%) had an asymptomatic drop in the LVEF of 20 percentage points; 27 patients (15.6%) experienced grade 2 cardiac toxicity; and 18 patients (10.4%) experienced grade 3 cardiac toxicity. There was one cardiac related death (0.5%). Cardiac event-free survival was 87.3% at 1 year. All but four patients had improved LVEF or symptoms of CHF after stopping trastuzumab or with appropriate therapy. After complete recovery, 26 patients were re treated with trastuzumab; 16 patients did not experience further CE. Concomitant taxane use was the only factor significantly associated with a CE (HR: 4.37, 95%CI 1.06–17.98, p:0.04).Prior anthracycline exposure was not associated with increased risk of CE. Conclusions: The risk of cardiac toxicity of long-term trastuzumab-based therapy is acceptable in this population, and this toxicity is reversible in the majority of the patients. In patients who have experienced a CE, additional treatment with trastuzumab can be considered after recovery of cardiac function. The increased risk of cardiotoxicity associated with taxane administration needs to be further investigated. No significant financial relationships to disclose.

Myxomas comprise 50% of all benign cardiac tumors in adults, with the right atrium as their second most frequent site of origin. Surgical resection is the only effective therapeutic option for patients with these tumors. The association between right atrial myxomas and severe left ventricular systolic dysfunction is extremely rare and makes treatment even more challenging. This was the case for our patient, a 47-year-old male with a right atrial mass and a severely impaired left ventricular function, with a 20% ejection fraction. Global enlargement of the heart was also noted, with moderate right ventricular dysfunction. The tumor was successfully excised using the on-pump beating heart technique, with an immediate postoperative improvement of the left ventricular ejection fraction to 35%. The technique proved useful, with no increased risk to the patient.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The Danish Heart Foundation Background In acute heart failure (AHF), low systolic blood pressure (SBP) has been associated with poor outcome. Less is known of the risk related to normal versus elevated SBP and interaction with left ventricular ejection fraction. Purpose The aim of the present study was to assess the association between baseline SBP and short- and long-term outcome in a large cohort of AHF-patients. Methods A pooled cohort of four randomized controlled trials investigating the vasodilator serelaxin versus placebo in patients admitted with AHF and an SBP from 125 to 180 mmHg. Endpoints were 180-day all-cause mortality and a short-term composite endpoint (worsening heart failure, all-cause mortality or hospital readmission for HF through Day 14). Left ventricular ejection fraction (LVEF) was categorized into HFrEF (&lt;40%) and HFpEF (= &gt;40%). Multivariable Cox regression was used and adjusted for age, sex, baseline body mass index, HFrEF, serum estimated glomerular filtration rate, allocated treatment (placebo/serelaxin), diabetes mellitus, ischemic heart disease, and atrial fibrillation/flutter. Measurements and Main Results A total of 10.533 patients with a mean age of 73 (±12) years and median SBP of 140 (130-150) mmHg were included within mean 8.2 hours from admission. LVEF was assessed in 8493 (81%), and of these, 4294 (51%) had HFrEF. Increasing SBP as a continuous variable was inversely associated with 180-day mortality (HRadjusted: 0.93 [0.88-0.98], p = 0.004 per 10 mmHg increase) and with the composite endpoint (HRadjusted: 0.90 [0.85-0.95], p &lt; 0.0001 per 10 mmHg increase). A significant interaction was observed regarding LVEF, revealing that SBP was not associated with mortality in patients with HFpEF  (HRadjusted: 1.01 [0.94-1.09], p = 0.83 per 10 mmHg increase), but SBP was associated with increased mortality in HFrEF (HRadjusted: 0.80 [0.73-0.88], p &lt; 0.001 per 10 mmHg increase) (Figure). Conclusions Elevated SBP is independently associated with favorable short- and long-term outcome in AHF-patients. The association between SBP and mortality was, however, not present in patients with preserved LVEF. Abstract Figure. Survival plots by SBP and LVEF

Abstract Aims It is not known whether transaortic flow rate (FR) in aortic stenosis (AS) differs between men and women, and whether the commonly used cut-off of 200 mL/s is prognostic in females. We aimed to explore sex differences in the determinants of FR, and determine the best sex-specific cut-offs for prediction of all-cause mortality. Methods and results Between 2010 and 2017, a total of 1564 symptomatic patients (mean age 76 ± 13 years, 51% men) with severe AS were prospectively included. Mean follow-up was 35 ± 22 months. The prevalence of cardiovascular disease was significantly higher in men than women (63% vs. 42%, P &lt; 0.001). Men had higher left ventricular mass and lower left ventricular ejection fraction compared to women (both P &lt; 0.001). Men were more likely to undergo an aortic valve intervention (AVI) (54% vs. 45%, P = 0.001), while the death rates were similar (42.0% in men and 40.6% in women, P = 0.580). A total of 779 (49.8%) patients underwent an AVI in which 145 (18.6%) died. In a multivariate Cox regression analysis, each 10 mL/s decrease in FR was associated with a 7% increase in hazard ratio (HR) for all-cause mortality (HR 1.07; 95% CI 1.03–1.11, P &lt; 0.001). The best cut-off value of FR for prediction of all-cause mortality was 179 mL/s in women and 209 mL/s in men. Conclusion Transaortic FR was lower in women than men. In the group undergoing AVI, lower FR was associated with increased risk of all-cause mortality, and the optimal cut-off for prediction of all-cause mortality was lower in women than men.
