Valve-in-Mitral Annular Calcification Transcatheter Mitral Valve Replacement After Thrombosis of Extracardiac Valved Conduit.

We report a patient with severe mitral annular calcification, mitral stenosis/regurgitation, hypertrophic obstructive cardiomyopathy, and subaortic membrane treated with valved left atrium-left ventricle conduit, septal myectomy, and membrane resection. Subsequent thrombosis of the conduit prompted successful valve-in- mitral annular calcification transcatheter mitral valve replacement and laceration of the anterior mitral leaflet to prevent outflow obstruction.

Risk factors for percutaneous left ventricular assist device explant complications.

Introduction: Percutaneous left ventricular assist device (pLVAD) explant remains nonstandardized with potential complications of bleeding and thrombosis. Explant settings include percutaneous techniques in the catheterization laboratory (CL), manually at bedside (MB), and surgically in the operating room (OR).

Objective: Identify high-risk features for explant-related complications, including indication for support, setting, and technique.

Disparate impact of severe aortic and mitral regurgitation on left ventricular dilation.

In asymptomatic severe aortic (AR) and mitral regurgitation (MR), left ventricular (LV) dimension criteria were established to guide timing of valve replacement to prevent irreversible LV dysfunction. Given both lesions are primary LV volume overload ''leaks'', it might be expected that both lesions would induce similar impact on the LV and result in equivalent dimension criteria for intervention. However, the dimension-based intervention criteria for AR versus MR (developed through natural history studies), differ markedly.

Transthoracic echocardiographic findings in patients admitted with SARS-CoV-2 infection.

Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-infected patients commonly have elevated troponin and D-dimer levels, but limited imaging exists to support most likely etiologies in efforts to avoid staff exposure. The purpose of this study was to report transthoracic echocardiographic (TTE) findings in SARS-CoV-2 patients with correlating troponin and D-dimer levels.

Methods: We identified 66 SARS-CoV-2 patients (mean age 60 ± 15.
