OBJECTIVES The aim of this study was to determine the safety of eliminating the pre-discharge transthoracic echocardiogram (TTE) on 30-day outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND TTE is utilized before, during, and after TAVR. Post-procedural, pre-discharge TTE assists in assessment of prosthesis function and detection of clinically significant paravalvular leak (PVL) after TAVR. METHODS Patients who underwent TAVR at Mayo Clinic from July 2018 t...

AIMS Chronic volume-overload can impair systolic and diastolic myocardial properties. We tested the hypothesis that Intrinsic Cardiac Elastography may detect alterations in passive myocardial elasticity in patients with chronic severe mitral regurgitation (MR) and predict worsening left ventricular (LV) function after mitral valve repair (MVr). METHODS AND RESULTS Comprehensive transthoracic echocardiography and cardiac elastography were performed in 80 patients with primary MR (prolapse and/or ...

Background null The predictors and clinical significance of increased Doppler-derived mean diastolic gradient (MG) following transcatheter edge-to-edge mitral valve repair (MVTEER) remain controversial. null Objective null We sought to examine baseline correlates of Doppler-derived increased MG post-MVTEER and its impact on intermediate-term outcomes. null Methods null Patients undergoing MVTEER were analyzed retrospectively. Post-MVTEER increased MG was defined as >5 mmHg or aborted clip implan...

BACKGROUND Atrial fibrillation (AF) is a low-flow state and may underestimate aortic stenosis (AS) severity. Single-high Doppler signals (HS) consistent with severe AS (peak velocity ≥4 m/s or mean gradient ≥40 mm Hg) are averaged down in current practice. The objective for the study was to determine the significance of HS in AF low-gradient AS (LGAS). METHODS One thousand five hundred forty-one patients with aortic valve area ≤1 cm2 and left ventricular ejection fraction ≥50% were identified an...

Objective To comprehensively explore contemporary differences between bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) patients with chronic haemodynamically significant aortic regurgitation (AR). Methods Consecutive patients with chronic ≥moderate-severe AR from a tertiary referral centre (2006–2017) were included. All-cause mortality, surgical indications and aortic valve surgery (AVS) were analysed. Results Of 798 patients (296 BAV-AR, age 46±14 years; 502 TAV-AR, age 67±14 years,...

OBJECTIVES To determine the incidence, characteristics, and outcomes of patients with hemolysis after transcatheter mitral valve replacement (TMVR). BACKGROUND Hemolysis is an increasingly recognized complication of TMVR. Clinical outcomes and optimal management for patients with hemolysis after TMVR are unclear. METHODS Patients that underwent mitral valve-in-valve (MViV), valve-in-ring (MViR), and valve-in-mitral annular calcification (ViMAC) at a single center were retrospectively assessed. R...
