Residual left atrioventricular valve regurgitation after conventional repair technique for partial atrioventricular septal defect most commonly occurs in the central position. We describe here the technique for bridging annuloplasty on the opposing anterior and posterior annuli of the atrioventricular valve in selected patients with short leaflets.

Background: This study aimed to determine whether artificial intelligence (AI)-based automated assessment of left atrioventricular coupling index (LACI) can provide incremental value above other traditional risk factors for predicting mortality among patients with severe aortic stenosis (AS) undergoing coronary CT angiography (CCTA) before transcatheter aortic valve replacement (TAVR).
Methods: This retrospective study evaluated patients with severe AS who underwent CCTA examination before TAVR between September 2014 and December 2020. An AI-prototype software fully automatically calculated left atrial and left ventricular end-diastolic volumes and LACI was defined by the ratio between them.

Background: In small children with left atrioventricular valve dysfunction, valve repair is preferred but some will require valve replacement. No prosthetic valve has growth potential, bioprostheses have poor durability, and mechanical prostheses have high rates of thromboembolic and hemorrhagic complications. We reviewed our experience with a modified bovine jugular vein valve designed for use in the right ventricular outflow tract (Melody valve, Medtronic) and compared this with contemporary mechanical valve replacement.

BACKGROUND Primary cardiac malignancies are extremely rare, with an incidence of 0.07% on autopsy series. Primary sarcomas represent up to 95% of malignant neoplasms, with myxofibrosarcomas accounting for only 10%.

Objectives: This study aims to investigate the association between interatrial conduction block and postoperative atrial fibrillation, which can precipitate acute cardiopulmonary instability and is associated with subsequent heart failure, stroke, and mortality following cardiac surgery.
Methods: Perioperative 12-channel electrocardiograms from 3405 patients undergoing myocardial revascularization, valve surgery, aortic surgery, or combinations thereof, were considered. Clinical and electrographic parameters were compared between patients with and without atrial fibrillation, and significant variables were analyzed using univariate and multivariate logistic regression.

Pectus excavatum (PE) can be associated with either congenital or acquired heart disease. This study highlights the importance of PE surgical repair in cases of severe chest depression on the heart in underlying cardiac diseases exacerbating cardiopulmonary impairment. From January 2023 to March 2024, four male patients underwent PE repair, having heart disease including pericarditis, mitral valve prolapse, ventricular fibrillation arrest and type 1 second-degree atrioventricular block.
