A patient with borderline left ventricle successfully underwent biventricular repair following a staged surgical approach to promote left ventricular growth. Despite initial concerns about left ventricle size, apex formation and adequate size of atrioventricular valve indicated potential for future growth. The patient demonstrated significant left ventricular growth, resulting in stable biventricular circulation and a favourable outcome over a three-year postoperative follow-up period.Clinical Registration Number: Institutional Review Board of Osaka City General Hospital, number 1902139.

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Objectives: Ischemia/reperfusion (IR)-induced ventricular arrhythmia, which mainly occurs after the opening of coronary artery occlusion, poses a clinical problem. This study aims to investigate the effectiveness of pretreatment with coenzyme Q (CoQ) in combination with mitochondrial transplantation on IR-induced ventricular arrhythmias in aged rats.

Materials And Methods: Myocardial IR induction was performed by left anterior descending coronary artery occlusion for 30 min, followed by re-opening for 24 hr.

Background: Children with Tetralogy of Fallot (TOF) usually present with right heart abnormalities, however much is not known if these children presents with left ventricular dysfunction.

Objectives: This article is aimed to ascertain the left ventricular function of children with TOF compared with those without any congenital heart disease. It also elicits the correlation if any, between left ventricular mass and descending aorta blood flow.

Background: The initial outcomes of transcatheter aortic valve replacement in patients with left ventricular outflow tract calcification are poor. Furthermore, balloon-expandable transcatheter aortic valve replacement is associated with an increased risk of annular rupture, and self-expandable transcatheter aortic valve replacement is associated with worse post-operative residual paravalvular leakage grades. Therefore, developing an optimal method for transcatheter aortic valve replacement for patients with left ventricular outflow tract calcification is desirable.
