Abstract OBJECTIVES The aim of this study is to describe the temporal pattern of left atrial (LA) and left ventricular (LV) reverse remodelling and to evaluate the impact of residual LV hypertrophy on the prognosis of patients with severe aortic stenosis and asymmetric septal hypertrophy undergoing aortic valve replacement (AVR). METHODS We retrospectively reviewed 59 consecutive patients who underwent AVR for severe aortic stenosis and asymmetric septal hypertrophy. They were divided into the normal LV mass group and the residual LV hypertrophy group according to the LV mass index (LVMI) 2 years after AVR. Thirty patients were eligible for analysis of the time-dependent changes in LA and LV reverse remodelling. RESULTS The interventricular septal thickness and LVMI gradually decreased and reached their lowest points 2 years after operation, whereas the LA dimension rapidly decreased in the early postoperative period and plateaued at 3 months. The multivariable analysis revealed a higher preoperative LVMI [odds ratio 6.36 (1.678–24.11); P = 0.007] as an independent predictor of residual hypertrophy 2 years after operation. The Cox proportional hazards model showed that a higher postoperative peak velocity [hazard ratio 6.715 (1.405–32.104); P = 0.017] was an independent predictor of long-term non-fatal cardiovascular hospitalization. Patients with residual hypertrophy 2 years after AVR had a higher rate of non-fatal cardiovascular hospitalization (P = 0.014). CONCLUSIONS For patients with severe aortic stenosis and asymmetric septal hypertrophy, maximum LA recovery occurred 3 months after AVR, whereas maximum LV recovery occurred 2 years thereafter. A higher preoperative LVMI may lead to postoperative residual hypertrophy, which is associated with adverse clinical outcomes.

Objective: Asymmetric septal hypertrophy (ASH) in patients with severe aortic stenosis (AS) has been associated with increased perioperative morbidity and mortality in smaller studies with severe aortic stenosis (AS). This association has not been tested in a large, longitudinal study. Methods: Clinical, echocardiographic and outcome data from 1730 patients with asymptomatic AS, participated in the Simvastatin Ezetimibe in Aortic Stenosis study (SEAS), a randomized placebo controlled study evaluating the effect of lipid lowering medications on progression of AS, were used. ASH was considered present if interventricular septal/posterior wall thickness ratio exceeded 1.5. The association of ASH with rate of major cardiovascular (CV) events was tested in time-dependent cox-regression analysis. Results: During a median of 4.3 years follow-up, ASH developed in 17.0 % of patients, and was associated with higher left ventricular mass (LVM) and body mass index (BMI) compared to non-ASH patients (all p<0.05). In time-varying Cox regression analysis, ASH predicted a 50% greater incidence of ischemic CV events (ICE), a 63% greater incidence in the need for coronary artery bypass grafting (CABG) at the time of aortic valve replacement, and a 2-fold higher incidence of hospitalization for heart failure due to progression of AS (CHFAS) independent of important confounders (all p<0.05) (Table). Conclusions: Development of ASH during progression of AS was a strong predictor of major CV events in patients participating in the SEAS-study.

ObjectiveTo determine whether echocardiography-derived left ventricular filling pressure influences survival in patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR).MethodsWe retrospectively reviewed 1383 consecutive patients with severe AS, normal ejection fraction and interpretable filling pressure undergoing AVR. Left ventricular filling pressure was determined according to current guidelines using mitral inflow, mitral annular tissue Doppler, estimated right ventricular systolic pressure and left atrial volume index. Cox proportional hazards regression was used to assess the influence of various parameters on mortality.ResultsAge was 75±10 years and 552 (40%) were female. Left ventricular filling pressure was normal in 325 (23%), indeterminate in 463 (33%) and increased in 595 (43%). Mean follow-up was 7.3±3.7 years, and mortality was 1.2%, 4.2% and 18.9% at 30 days and 1 and 5 years, respectively. Compared with patients with normal filling pressure, patients with increased filling pressure were older (78±9 vs 70±12, p<0.001), more often female (45% vs 35%, p=0.002) and were more likely to have New York Heart Association class III–IV symptoms (35% vs 24%, p=0.004), coronary artery disease (55% vs 42%, p<0.001) and concentric left ventricular hypertrophy (63% vs 37%, p<0.001). After correction for other factors, increased left ventricular filling pressure remained an independent predictor of mortality after successful AVR (adjusted HR 1.45 (95% CI 1.16 to 1.81), p=0.005).ConclusionsPreoperative increased left ventricular filling pressure is common in patients with AS undergoing AVR and has important prognostic implications, regardless of symptom status. Future prospective studies should consider whether patients with increased filling pressure would benefit from earlier operation.

Background and Hypothesis: The sensitivity of LVH analysis by ECG voltage criteria in patients with severe aortic valve stenosis undergoing trans-catheter aortic valve replacement (TAVR) has not yet been studied. LVH is expected in the TAVR population and would be reflected in voltage criteria by ECG. Methods: A retrospective chart review was conducted in 176 consecutive TAVR patients without ventricular-paced rhythm. ECG data was collected and analyzed by Sokolow-Lyon and Cornell Voltage criteria. Results were compared to transthoracic echocardiogram. Analyses of variation, correlation, chi-square, and logistic regression were used. The study was approved by the institutional IRB. Results: Sokolow-Lyon and Cornell Voltage criteria for LVH were present and concordant in 19% (33 of 176) of patients; in 49% (86 of 176) of patients, neither criteria was suggestive for LVH. Only 19% (34 of 176) of patients had LVH by Cornell Voltage and 13% (23 of 176) by Sokolow-Lyon criteria, indicative of poor concordance between these two commonly used ECG criteria for LVH (p<0.0001). Ejection fraction, aortic valve gradient, aortic valve area, COPD, PVD, prior stroke, dyslipidemia, and hypertension did not affect the prevalence of LVH by either or both criteria. Women (p<0.01) and patients with rhythm other than atrial fibrillation (p<0.0053) were more likely to have voltage criteria for LVH, while older adults were more likely to meet criteria for LVH. Concordant LVH criteria were noted in patients 84.6 +/- 7.2 years of age, while patients without LVH by ECG voltage criteria were significantly younger at 80.21 +/- 8.1 years of age (p<0.007). Conclusion: The presence of LVH by Sokolow-Lyon and Cornell ECG voltage criteria poorly correlates with the presence of LVH and critical aortic stenosis in TAVR patients. Women are more likely to have voltage criteria for LVH. Therefore, ECG may not be a suitable method of screening patients with severe aortic stenosis for LVH, especially in men.
