Double-outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both the aorta and pulmonary artery arise completely or predominantly from the left ventricle. DOLV is a spectrum and can be classified depending on the position of the ventricular septal defect (VSD) relative to the great vessels, the relationship of the great vessels, and the presence or absence of pulmonary or aortic outflow obstruction. In the absence of tricuspid atresia or hypoplastic right ventricle, two ventricle repair is the preferred surgical treatment. We report a 31-day-old, 2.1 kg neonate with DOLV, subaortic VSD who underwent a successful arterial switch with VSD closure.

Cardiovascular Department, Tokushima University Hospital, Tokushima, Japan.
Background: Speckles tracking echocardiography imaging enables clinicians to detect subtle systolic dysfunction. The aim of the present study was to elucidate the differences in speckle tracking echocardiographic findings between immunoglobulin light chain amyloid cardiomyopathy (AL-CM) and transthyretin amyloid cardiomyopathy (TTR-CM).
Methods: The patients with a confirmed diagnosis of cardiac amyloidosis through cardiac biopsy from March 2013 to October 2022 were included.

Background: Idiopathic right bundle branch block (RBBB) is often seen as harmless and common. However, many studies show it might be linked to negative health outcomes. So, it is crucial to fully understand how RBBB affects the heart's ventricles.

Background: A partial atrioventricular septal defect (AVSD) with a hypoplastic left ventricle and common atrium is a rare combination of cardiac anomalies that can be associated with Ellis-van Creveld (EVC) syndrome.
Case Summary: A female neonate with EVC syndrome was diagnosed with an unbalanced AVSD and hypoplastic left ventricle. Pulmonary artery banding and ductus ligation were performed at 23 days after birth.

Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.

Object: To explore the mechanism of diabetic cardiomyopathy that hyperglycemia may affect the cardiac function by inhibiting the expression of ATPase β subunit.
Method: Cardiac function, fibrosis levels, and the expression of the ATPase β subunit were observed in Akita mice-a diabetes mice model without lipid metabolism disorders--using morphological, molecular biology, and echocardiographic analyses compared to wild-type mice. The study revealed a connection between the decreased ATPase β subunit and the development of diabetic myocardial injury.
