We report on a 40-year-old woman referred for evaluation of a cardiac murmur and dyspnea on exertion. The electrocardiogram (ECG) showed incomplete right bundle branch block, and echocardiography revealed a large atrial septal defect (ASD, ostium secundum type) with dilated right-sided heart chambers. At cardiac catheterization, a large left-to-right shunt ...

The hallmark of an atrioventricular septal defect (AVSD) is a common atrioventricular junction, giving rise to a trileaflet left atrioventricular valve. AVSDs have the potential for interatrial shunting alone, interventricular shunting alone, or both. AVSDs without interatrial or interventricular communications have been identified at postmortem examination, but there are no ...

Pulmonary artery banding is a palliative surgical procedure used to treat functionally univentricular hearts, multiple ventricular septal defects and complete atrioventricular septal defects. Pulmonary artery banding has recently gained in interest for left ventricular retraining and hypoplastic left heart malformations. The indication for pulmonary artery banding is limited by several ...

About 10%-15% of patients with an atrial septal defect will have some form of anomalous pulmonary venous connection. With the advent of percutaneous closure of atrial septal defects, it is imperative that presence of partial anomalous pulmonary venous return be excluded to prevent unnecessary percutaneous closure in patients who would ...

A 3-year-old boy underwent interventional closure of an atrial septal defect using an Amplatzer septal occluder. After 4 weeks, an aortic sinus-to-left atrial fistula was detected by echocardiography in an asymptomatic child. The device was surgically explanted with fistula and atrial septal defect closure. Follow-up was uneventful.

Dilated cardiomyopathy and the resultant left ventricular dysfunction are risk factors for thrombus formation in the heart, reflecting the intimate relationship between structure and function in this vital organ. Once formed, depending on size, location, and mobility, left ventricular thrombi have the tendency to embolize, sometimes with dire consequences. Proper ...

Unilateral agenesis of the pulmonary artery is a rare congenital anomaly that is commonly associated with ventricular septal defect (VSD). Its clinical presentation is diverse, and if left untreated, it can lead to significant damage and even death. Several surgical techniques have been developed for its management, with variable results. ...

The presence of a patent foramen ovale in patients with heart failure can be missed during echocardiography despite the use of provocative maneuvers. Implantation of a left ventricular assist device in these patients can result in right-to-left shunting and hypoxemia. We report the use of a percutaneous atrial septal defect ...

Ventricular septal defects (VSDs) complicate the arterial switch operation (ASO) in newborns with transposition of the great arteries because of prolonged cardiac arrest time and subsequent ventricular dysfunction. Three newborns with paramembranous VSDs were successfully treated using the newly designed Amplatzer membranous VSD occluder during the ASO. The implantation of ...
