Bioprosthetic heart valves (BHVs) constructed from bovine pericardium (BP) are widely used in valve replacement due to their favorable biocompatibility. However, early structural degeneration, particularly in younger recipients, remains a critical challenge, primarily driven by calcification. Trimethylamine N-oxide (TMAO), a gut microbiota-derived metabolite elevated by high-choline diets, has been implicated in vascular and valvular calcification, but its role in BHV deterioration remains...

A 77-year-old man was admitted for catheter ablation due to frequent premature ventricular complexes (PVCs). Activation mapping revealed that the earliest ventricular activation during the PVC was recorded on ...

Cardiac herniation is a rare complication after pulmonary surgery. A 59-year-old woman underwent right-sided pneumonectomy for right pulmonary squamous cell carcinoma, pulmonary vein was ligated intrapericardialy and the pericardial defect, which mesasured about 2 cm was not repaired. After four months, the patient complained of bilateral lower leg edema and dyspnea on effort. Computed tomography (CT) showed the right atrial herniation into the right-sided thoracic cavity. We diagnosed with...

Cardiac patches to repair myocardial defects require mechanically stable materials that prevent bleeding and can be implanted via suturing. The current clinical standard, bovine pericardial patches (BPPs), serve this purpose but do not degrade or integrate with the myocardium, limiting their long-term effectiveness. Here, we present the reinforced cardiac tissue patch (RCPatch). This multimaterial patch comprises a stiffness-tuned, cardiomyocyte-infiltrated 3D metamaterial and a suturable,...

We analyzed our data to evaluate the safety and feasibility of intraoperative extracorporeal membrane oxygenation and intra-aortic balloon pump use in acute type A aortic dissection repair.

Cardiac rehabilitation (CR) stands as a crucial therapeutic measure for improving the prognosis of individuals afflicted with cardiovascular ailments. This investigation seeks to examine the efficacy of CR tra...

In recent years, the use of Left Ventricular Assist Devices (LVAD) in the treatment of heart failure has been increasingly widespread. Not only do they provide circulatory support for patients, but the reverse...

Atherosclerosis (AS) is increasingly recognized as a chronic inflammatory disease that significantly impacts vascular health and contributes to cardiovascular disorders. LGALS3BP, a well-studied molecule, play...
