Changes in stent-graft orientation after frozen elephant trunk treatment in aortic arch aneurysm.

Background: Changes in stent graft (SG) orientation after frozen elephant trunk (FET) treatment for aortic arch aneurysms are not well understood. This study investigated changes in SG orientation and their effects on aortic events after FET for aortic arch aneurysms.

Methods: This study included 57 patients with true aneurysms who underwent elective total arch replacement using FET between 2016 and 2023.

Additional left atrial plication improves postoperative cardiovascular events in atrial functional mitral regurgitation.

Background: Left atrial (LA) plication is a procedure used to correct an LA that expands posteriorly due to remodeling. This study aimed to determine the efficacy of additional LA plication in reducing postoperative cardiovascular events (CVEs) after mitral valve (MV) repair in atrial functional mitral regurgitation (MR) patients.

Methods: Between October 2008 and August 2023, MV repair with or without LA plication in 74 patients was studied.

Three-dimensional computed tomography analysis of the mitral annulus for mitral annuloplasty in 100 cases of robotic mitral valve repair.

Objectives: This study aimed to evaluate the efficacy of preoperative computed tomography in assessing mitral annulus anatomy and the posterior annular plication rate in mitral valve repair with annuloplasty.

Methods: From July 2018 to August 2023, we performed robotic mitral valve repair with ring annuloplasty using a semi-rigid ring in 100 patients. Preoperative anatomical assessment of the mitral annulus was conducted by three-dimensional computed tomography.

Midterm Results of Mitral Valve Repair Using Loop Technique With Simple Height Reduction of the Large Posterior Leaflet.

Objective: Systolic anterior motion (SAM) is one of the most serious problems in mitral valve repair. Height reduction is a key procedure to solve SAM, and there are limited data on the surgical results of height reduction procedure. This study is to assess the effectiveness and midterm results of simple height reduction procedure for SAM in patients with severe mitral regurgitation (MR).
