Abstract Introduction Aortic stenosis (AS) is the most prevalent form of acquired valvular heart disease, it affects ∼2% of people aged over 75. Series of compensatory mechanisms occur, in order for LV to adapt to high pressure overload. Aortic valve replacement has been the mainstay AS treatment either surgically or percutaneously. The evaluation of myocardial strains after Transcatheter Aortic Valve Implantation (TAVI) and Surgical Aortic Valve Replacement (SAVR) is still underexplored and there is no single study to date scouting the difference between TAVI and SAVR. Aim To assess the impact of unloading LV after TAVI and SAVR on LV remodelling. Methods In this prospective study, we have recruited 111 patients (75±11 years, 63% were females) with varying degrees of aortic stenosis. Of the 111 patients, 43 patients and 11 patients underwent TAVI and SAVR respectively between November 2017 and May 2018. Demographics, clinical and echocardiographic measurements along with speckle tracking parameters were recorded for all participants and again 4±2 weeks after intervention. Results Pre-TAVI LV-GLS mean was −10.8±3.5% and after implantation of aortic prosthesis immediate improvement of the myocardial deformation to −13.98±2.9% was observed after one month of the intervention, mean difference of −3.16% following procedure. There was an evidence of significant improvement in LV-GRS after TAVI (44.86±12.9% to 49.77±10.8%, P value= 0.047). Per contra, when comparing pre and post TAVI LV-GCS, no statistical evidence was noted. However, a difference of −2.4% in GCS following the intervention might be clinically important, but no previous evidence can support this. This is attributed to the poor reproducibility and yet not available standardisation.

The Impact

Background: It is well known that there is a significant gender gap in both the referral and outcomes of patients eligible for cardiac surgery. The impact of transcatheter aortic valve replacement (TAVR) on the gender disparity in the management of aortic stenosis (AS) has not been well established. The aim of this study was to analyze the referrals to and outcomes of both surgical aortic valve replacement (SAVR) and TAVR for management of AS as a function of gender in a contemporary United States population. Methods: We used the National Inpatient database 2009-2015 to study the gender distribution of admissions for both SAVR and TAVR for the treatment of AS and its effect on inpatient outcomes. The survey estimation commands were used to determine weighted national estimates. Results: During the study period there were 3,443,274 (Males (M) 46.6 ± 0.1%; Females (F) 53.3 ± 0.1%) admissions for AS diagnosis, 325,264 SAVR (M 62.0 ± 0.2%; F 37.9 ± 0.2%) and 56,542 TAVR (M 52.6 ± 0.5%; F 47.3 ± 0.5%). The gender disparity was more prominent in Whites (Wh) than Non-whites (NWh) for both SAVR (Wh M 62.7 ± 0.2%, Wh F 37.2 ± 0.2%; NWh M 57.3 ± 0.5%, NWF 42.6 ± 0.5%) and TAVR (Wh M 53.1 ± 0.5%, Wh F 46.8 ± 0.5%; NWh M 47.2 ± 1.3%, NWh F 52.7 ± 1.3%). Female TAVR patients were older and more likely to have Medicare but less likely to have diabetes, chronic kidney disease (CKD), peripheral artery disease (PAD), prior coronary bypass surgery (CABG) and percutaneous coronary intervention (PCI), and chronic obstructive pulmonary disease (COPD). They also had lower Charlson comorbidity index (CCI). However, female TAVR patients had higher inpatient deaths (OR = 1.34;1.09-1.64), bleeding (OR = 1.51; 1.40-1.62) and stroke (OR = 1.47; 1.16-1.88), but a lower rate of pacemaker implantation (0.86; 0.76-0.97) and acute renal failure (ARF) (OR = 0.78; 0.71- 0.87). SAVR females were older, more likely to have Medicare, hypertension, and heart failure but less likely to have diabetes, CKD, PAD, prior CABG and PCI, and COPD. They also had lower CCI. SAVR female patients had higher inpatient deaths (OR = 1.40; 1.29-1.53), pacemaker implantation (OR =1.19; 1.11-1.28), blood transfusion (OR = 1.40; 1.35-1.45), and stroke (OR =1.19; 1.08-1.30), but lower ARF (OR = 0.80; 0.76-0.83). Conclusion: A gender disparity in the management of aortic stenosis continues to exist; however, our study showed that TAVR appears to bridge this gap. The reduction in gender disparity was most pronounced among Non-white patients. Despite having less comorbidities, outcomes after both SAVR and TAVR remain worse in women.

AbstractThe increasing prevalence of patients with aortic stenosis worldwide highlights a clinical need for improved and accurate prediction of clinical outcomes following surgery. We investigated patient demographic and cardiovascular magnetic resonance (CMR) characteristics to formulate a dedicated risk score estimating long-term survival following surgery. We recruited consecutive patients undergoing CMR with gadolinium administration prior to surgical aortic valve replacement from 2003 to 2016 in two UK centres. The outcome was overall mortality. A total of 250 patients were included (68 ± 12 years, male 185 (60%), with pre-operative mean aortic valve area 0.93 ± 0.32cm2, LVEF 62 ± 17%) and followed for 6.0 ± 3.3 years. Sixty-one deaths occurred, with 10-year mortality of 23.6%. Multivariable analysis showed that increasing age (HR 1.04, P = 0.005), use of antiplatelet therapy (HR 0.54, P = 0.027), presence of infarction or midwall late gadolinium enhancement (HR 1.52 and HR 2.14 respectively, combined P = 0.12), higher indexed left ventricular stroke volume (HR 0.98, P = 0.043) and higher left atrial ejection fraction (HR 0.98, P = 0.083) associated with mortality and developed a risk score with good discrimination. This is the first dedicated risk prediction score for patients with aortic stenosis undergoing surgical aortic valve replacement providing an individualised estimate for overall mortality. This model can help clinicians individualising medical and surgical care.Trial Registration ClinicalTrials.gov Identifier: NCT00930735 and ClinicalTrials.gov Identifier: NCT01755936.

Abstract Aims Despite improvements in cardiac haemodynamics and symptoms, long-term mortality remains increased in some patients after aortic valve replacement (AVR). Limited data exist on the prognostic role of left ventricular (LV) chamber stiffening in these patients. Methods and results We performed a retrospective analysis in 1893 patients with severe aortic stenosis (AS) referred for AVR. LV end-diastolic pressure–volume relations (EDPVR, P = αV^β) were reconstructed from echocardiographic measurements of end-diastolic volumes and estimates of end-diastolic pressure (EDP). The impact of EDPVR-derived LV chamber stiffness (CS30, at 30 mmHg EDP) on all-cause mortality after AVR was evaluated. Mean age was 76 ± 10 years, 39% were females, and ejection fraction (EF) was 61 ± 12%. The mean LV chamber stiffness (CS30) was 2.2 ± 1.3 mmHg/mL. A total of 877 (46%) patients had high LV stiffness (CS30 &gt;2 mmHg/mL). In these patients, the EDPVR curves were steeper and shifted leftwards, indicating higher stiffness at all pressure levels. These patients were slightly older, more often female, and had more prevalent comorbidities compared to patients with low stiffness. At follow-up [median 4.2 (interquartile range 2.8–6.3) years; 675 deaths], a higher CS30 was associated with lower survival (hazard ratio: 2.7 for severe vs. mild LV stiffening; P &lt; 0.0001), both in patients with normal or reduced EF. At multivariate analysis, CS30 remained an independent predictor, even after adjusting for age, sex, comorbidities, EF, LV remodelling, and diastolic dysfunction. Conclusion Higher preoperative LV chamber stiffening in patients with severe AS is associated with poorer outcome despite successful AVR.

Abstract OBJECTIVES The aim of this study was to evaluate the incidence and prognostic impact of paravalvular regurgitation (PVR) on the outcome after transcatheter (TAVR) and surgical aortic valve replacement (SAVR) for aortic stenosis. METHODS The nationwide FinnValve registry included data on 6463 consecutive patients who underwent TAVR (n = 2130) or SAVR (n = 4333) with a bioprosthesis for the treatment of aortic stenosis during 2008–2017. The impact of PVR at discharge after TAVR and SAVR on 4-year mortality was herein investigated. RESULTS The rate of mild PVR was 21.7% after TAVR and 5.2% after SAVR. The rate of moderate-to-severe PVR was 3.7% after TAVR and 0.7% after SAVR. After TAVR, 4-year survival was 69.0% in patients with none-to-trace PVR, 54.2% with mild PVR [adjusted hazard ratio (HR) 1.64, 95% confidence interval (CI) 1.35–1.99] and 48.9% with moderate-to-severe PVR (adjusted HR 1.61, 95% CI 1.10–2.35). Freedom from PVR-related reinterventions was 100% for none-to-mild PVR and 95.2% for moderate-to-severe PVR. After SAVR, mild PVR (4-year survival 78.9%; adjusted HR 1.29, 95% CI 0.93–1.78) and moderate-to-severe PVR (4-year survival 67.8%; adjusted HR 1.36, 95% CI 0.72–2.58) were associated with worse 4-year survival compared to none-to-trace PVR (4-year survival 83.7%), but the difference did not reach statistical significance in multivariable analysis. Freedom from PVR-related reinterventions was 99.5% for none-to-trace PVR patients, 97.9% for mild PVR patients and 77.0% for moderate-to-severe PVR patients. CONCLUSIONS This multicentre study showed that both mild and moderate-to-severe PVR were independent predictors of worse survival after TAVR. Mild and moderate-to-severe PVR are not frequent after SAVR, but tend to decrease survival also in these patients. Clinical trial registration number ClinicalTrials.gov Identifier: NCT03385915.

Introduction: Greater than mild paravalvular regurgitation (PVR) is reported to worsen late mortality after transcatheter aortic valve replacement (TAVR). However the impact of PVR on the prognosis after surgical aortic valve replacement (SAVR) is not determined. The purpose of this study was to investigate the impact of PVR on the prognosis after SAVR in patients with aortic stenosis (AS) using intraoperative transesophageal echocardiography (iTEE). Hypothesis: We hypothesized that the prognosis of mild PVR after SAVR in patients with AS is benign. Methods: We retrospectively reviewed 304 consecutive patients with severe AS who underwent isolated SAVR using bioprosthesis and who had color Doppler iTEE images after SAVR. Severity of PVR was determined by the sum of the cross-sectional area of the vena contracta (VCA) using 2D color Doppler just after SAVR. Grading of PVR was determined using the following VCA cutoffs: trivial 0-4 mm2; mild 5-9 mm2; moderate 10-29 mm2; severe ≥ 30 mm2. We investigated the clinical course after SAVR including death, re-hospitalization due to heart failure exacerbation, and reoperation. Results: The patients were 76 ± 10 years old, and 57% were male. PVR was trivial in 28 patients (9%), mild in 18 (6%), moderate in 9 (3%), severe in 0. During the follow-up period of 1111 ± 582 days (median 1071 days), there were significant differences in survival between moderate and none/trivial or mild PVR group (p < 0.001 and 0.004, respectively). There was no significant differences in survival between mild and none/trivial PVR group (p = 0.69). Of 35 patients with ≥ mild PVR, only 3 patients with moderate PAR re-hospitalized for heart failure exacerbation and 1 of them resulted in successful percutaneous paravalvular leak closure. There was no other patient for reoperation except this patient. Conclusions: Although infrequent, moderate PVR showed worse survival following SAVR for severe AS, while the prognosis of mild PVR was benign.

The Impact

Objectives: Four patterns of left ventricular (LV) geometry have been described in aortic stenosis (AS): normal geometry, concentric remodelling (LVCR), concentric hypertrophy (CH), and eccentric hypertrophy (EH). LVCR and CH are independently associated with an increased risk of mortality in patients with medically managed AS. No data are available on the impact of aortic valve replacement (AVR) on the negative prognostic implications of LV remodelling patterns. Methods: This study evaluated the long-term postoperative prognostic value of preoperative LV patterns in a cohort of 779 patients (mean age 73 years) with severe AS and ejection fraction >50% undergoing AVR. Results: Long-term postoperative all-cause and cardiovascular mortality in patients with LVCR (adjusted HR = 0.50 [0.17-1.45], p = 0.202, and 0.45 [0.10-2.15], p = 0.373, respectively), CH (adjusted HR = 0.98 [0.68-1.40], p = 0.915, and 1.25 [0.60-2.40], p = 0.556, respectively), or EH (adjusted HR = 1.02 [0.79-1.32], p = 0.870, and 1.18 [0.70-1.99], p = 0.537, respectively) were comparable to those of patients with normal LV geometry. Conclusions: Despite the negative prognostic impact of LVCR and CH observed in patients with medically managed AS, these LV remodelling patterns are not associated with excess mortality after AVR. Surgery should therefore be discussed in patients with LVCR or CH and severe AS to avoid the risk of increased mortality observed under conservative management.

Echocardiographic Parameters

Abstract Background The 2016 guidelines of the American Society of Echocardiography (ASE) and European Association of Cardiovascular Imaging (EACVI) for evaluation of left ventricular (LV) diastolic dysfunction by Doppler flow and tissue Doppler- echocardiography do not adjust assessment of high filling pressures for patients with aortic stenosis (AS). However, most of the studies on this patient group indicate age independent specific diastolic features in AS. The aim of this study is to identify disease-specific range and distribution of diastolic functional parameters and their ability to identify high N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels as a marker for high filling pressures. Methods In this study, 169 patients who underwent surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) were prospectively enrolled. Resting echocardiography was performed including Doppler of the mitral inflow, pulmonary venous flow, tricuspid regurgitant flow and tissue Doppler in the mitral ring and indexed volume-estimates of the left atrium (LAVI). Echocardiography, and NT-proBNP levels were assessed before TAVR/SAVR and at two postoperative visits at 6 and 12 months. Results Pre- and postoperative values were septal e′; 5.1 ± 3.9, 5.2 ± 1.6 cm/s; lateral e′ 6.3 ± 2.1; 7.7 ± 2.7 cm/s; E/e′19 ± 8; 16 ± 7 cm/s; E velocity 96 ± 32; 95 ± 32 cm/s; LAVI 39 ± 8; 36 ± 8 ml/m2, pulmonary artery pressure (PAP) 39 ± 8; 36 ± 8 mmHg, respectively. The scoring recommended by ASE/EACVI detected elevated NT pro-BNP with a specificity of 25%. Adjusting thresholds towards PAP ≥ 40 mmHg, E velocity ≥ 100 cm/s, E deceleration time < 220 ms, and E/septal e′ ≥ 20 or septal e′ < 5.0 cm/s increased prediction of NT-proBNP levels ≥500 ng/L with substantially improved specificity (> 85%). Conclusion Diastolic echocardiographic parameters in AS indicate persistent impaired relaxation and NT-proBNP indicate elevated filling pressures in most of the patients, improving only modestly 6–12 months after TAVR and SAVR. Applying the 2016 ASE/EACVI recommendations for detection of elevated filling pressures to patients with AS, elevated NT pro-BNP levels could not be reliably detected. However, adjusting thresholds of the echocardiographic parameters increased specificities to useful diagnostic levels. Trial registration The study was prospectively approved by the regional ethical committee, REK North with the registration number: REK 2010/397-10.

Abstract Funding Acknowledgements Fundação Portuguesa para a Ciência e Tecnologia (SFRH/BD/104369/2014) and Sociedade Portuguesa de Cardiologia (“Bolsa de investigação João Porto”) OnBehalf EPICHEART Study Background Left atrial (LA) functional remodeling is an important mechanism in the pathophysiology of aortic stenosis (AS), and readily-assessable using speckle-tracking echocardiography (STE). It is uncertain whether and how surgical aortic valve replacement (SAVR) affects reverse LA functional remodeling. Aims We aimed to evaluate LA functional remodeling post-SAVR using STE and to explore potential underlying mechanisms. Methods 73 symptomatic severe AS patients (72.6 ± 8.14 years, 53.4% male) were assessed before and six months after SAVR (Fig.1-A). LA function was evaluated using STE-derived LA longitudinal strain during reservoir (LASr), conduit (LAScd) and contraction (LASct) phases (Fig1.-B); reverse LA remodeling was represented by their relative percentual changes. LA structure was assessed by LA area and indexed volume. Results LA structure and left ventricle (LV) indexed mass, end-diastolic diameter (LVEDD) and mean E/e" improved after SAVR (Table 1). Although paired-samples analysis did not show significant changes in LA function, multiple linear regression revealed that preoperative LA strain parameters were the sole baseline predictors of reverse LA remodeling: lower baseline LASr, LAScd and LASct were related to improved LASr, LAScd and LASct, respectively (Fig.1-C); mean E/e’ decrease was associated with LAScd improvement (Fig.1-D2). LV mass and LVEDD decrease were not associated with LA functional recovery. Conclusion Reverse LA functional remodeling is compromised after SAVR, and increased in patients with impaired baseline LA function. LV diastolic function recovery was linked to improved LA conduit function. An optimal echocardiographic cut-off should be further explored in order to better adjudicate surgical timing, and foster LA functional recovery.
