Aortico-left ventricular tunnel (ALVT) is a rare congenital anomaly presenting abnormal connection between the ascending aorta and the left ventricle. In most reported cases, the aortic end of the tunnel is above the right coronary sinus. Cases of ALVT related to the left aortic sinus are extremely rare. We herein report a case diagnosed preoperatively as ALVT arising from the left aortic sinus. The actual diagnosis observed at surgery was aortic valve insufficiency with a left ventricular outflow tract aneurysm. We successfully performed aortic valve repair and plication of the left ventricular aneurysm.

The adult mammalian heart is unable to undergo cardiac repair, limiting potential treatment options after cardiac damage. However, the fetal heart is capable of cardiac repair. In preparation for birth, cardiomyocytes (CMs) undergo major maturational changes that include exit from the cell cycle, hypertrophic growth, and mitochondrial maturation.

Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

Background: Cardiac magnetic resonance imaging (CMR) could serve as a robust tool for comprehensive evaluation of early changes across heart failure (HF) stages classified by the American Heart Association/American College of Cardiology guideline in diabetes mellitus (DM).
Objectives: The authors aimed to explore phenotypic imaging features characterizing DM participants at different HF stages by CMR.
Methods: DM participants with preserved ejection fraction who underwent CMR examination between January 2020 and December 2021 were evaluated.

Background: Supranormal left ventricular ejection fraction (LVEF) confers a paradoxically higher mortality risk; however, whether intrinsic structural changes of left ventricle (LV) play an important role remain unclear.
Objectives: The authors sought to investigate the prognostic implication of supranormal LVEF and its interaction with LV concentric remodeling.
Methods: Consecutive participants undergoing echocardiography in a tertiary medical center with LVEF >60% were included.
