Atrioventricular septal defects comprise a disease spectrum characterized by deficient atrioventricular septation, with several common features seen in all affected hearts and variability in atrioventricular valve morphology and interatrial and interventricular communications. Atrioventricular septal defects are among the more common defects encountered by pediatric cardiologists and echocardiographers. Despite advances in ...

Intra-Atrial Conduction Block. A 42-year-old woman with a history of cardiomyopathy and multiple ablation procedures for atrial tachycardia developed intra-atrial conduction block that mimicked atrioventricular (AV) nodal block during radiofrequency ablation at the cavotricuspid isthmus. She was treated with atrial pacing (from the coronary sinus), which overcame intra-atrial conduction block ...

Ventricular septal defect, a potentially deadly complication of transmural myocardial infarction, is often accompanied by ischaemic mitral regurgitation. It has been recognized that the presence and persistence of the latter negatively affect survival rates in patients after myocardial infarction. We present a simple endoventricular edge-to-edge technique of mitral repair using ...

Unroofed coronary sinus (coronary sinus-type atrial septal defect) is a rare congenital anomaly resulting from imperfect development of left atrio-venous fold. This malformation is not considered suitable for percutaneous treatment due to complex anatomy and risk of coronary sinus obstruction. This paper reports on the first successful treatment of partially ...

Extracorporeal membrane oxygenation (ECMO) is often used to provide cardiopulmonary support for infants experiencing severe levels of cardiac or respiratory failure. In patients with two ventricles and no intra-atrial communication, ECMO is often complicated by limited venous return to the circuit and marked left atrial hypertension. This condition may be ...

Cardiac cushion formation is crucial for both valvular and septal development. Disruption in this process can lead to valvular and septal malformations, which constitute the largest part of congenital heart defects. One of the signaling pathways that is important for cushion formation is the TGFβ superfamily. The involvement of TGFβ ...

Left atrial appendage (LAA) contrast filling defects are commonly found in patients undergoing multidetector cardiac computed tomography (CCT) before catheter ablation of atrial fibrillation. Delayed CCT allows quantification of the LAA delayed/initial attenuation ratio and improves accuracy for LAA thrombus detection, which may obviate routine transesophageal echocardiography (TEE) before ablation. ...
