Conduction Disorders after Rapid Deployment Aortic Valve Replacement Compared to Conventional Aortic Valve Replacement.

Objectives:  We evaluated and compared early postprocedural and midterm incidence and evolution of atrioventricular and intraventricular conduction disorders following rapid deployment aortic valve replacement (RDAVR) and conventional aortic valve replacement (AVR).

Materials And Methods:  One hundred and forty-seven patients who underwent isolated rapid deployment AVR between 2017 and 2021 as well as 128 patients after conventional biological AVR in the same period were included in this study. ECGs recorded at baseline, discharge, and 12 months were retrospectively analyzed.

Immobilization in External Rotation and Abduction Versus Arthroscopic Stabilization After First-Time Anterior Shoulder Dislocation: A Multicenter Randomized Controlled Trial.

Background: Treatment of first-time shoulder dislocation (FSD) is a topic of debate. After high rates of recurrent instability after nonoperative management were reported in the literature, primary repair of FSD significantly increased. At the same time, new concepts were proposed that had promising results for immobilization in external rotation (ER) and abduction (ABD).

Rapid-Deployment Aortic Valve Replacement after Previous Mechanical Valve Implantation.

Recent studies report a reproducible reduction of myocardial ischemic and cardiopulmonary bypass times along with excellent hemodynamics and low rates of paravalvular leakage for rapid-deployment valves. A 68-year-old female patient with aortic stenosis and a mechanical mitral valve which was implanted in 2006 received rapid-deployment aortic valve replacement. The procedure could be performed with a cross-clamp time of 45 minutes and a cardiopulmonary bypass time of 60 minutes.

Detection of valve malfunction after mechanical MVR using digital phonocardiography.

We present the case of a 63-year-old female patient who developed severe chronic dyspnea two years after mechanical mitral valve replacement (MVR). Conventional cardiac diagnostics including echocardiography, fluoroscopy, right and left heart catheterization could not detect any malfunction. Only digital phonocardiography was able to show alterations of the typical acoustic signal.
