Communication between the left ventricle and right atrium

Communication between the left ventricle and right atrium.

A further 15 patients with left ventricular/right atrial communication are reported, 14 of whom were treated surgically. The clinical triad of a ventricular septal defect murmur, cardiac enlargement, and an arteriovenous shunt at atrial level is characteristic of the malformation. Of the 14 patients accorded surgical treatment, one died soon after operation. The remainder are well, with both th...

Acute pressure overload of the right ventricle. Comparison of two models of right-left shunt. Pulmonary artery to left atrium and right atrium to left atrium: experimental study

BACKGROUND In right ventricular failure (RVF), an interatrial shunt can relieve symptoms of severe pulmonary hypertension by reducing right ventricular preload and increasing systemic flow. Using a pig model to determine if a pulmonary artery-left atrium shunt (PA-LA) is better than a right atrial-left atrial shunt (RA-LA), we compared the hemodynamic effects and blood gases between the two shu...

Lymphoma of the Right Atrium and Ventricle.

Direct communication between the right pulmonary artery and the left atrium.

Figure 1: Echocardiography showing, a large fistula with a diameter of 7 mm between the right pulmonary artery and the enlarged left atrium (A and B), CT scan showing an epidural hematoma (C). RA: right atrium; LA: left atrium; RPA: right pulmonary artery; AO: aorta; PA: pulmonary artery; RVOT: right ventricular outflow tract. Figure 2: Intraoperative view of the doubly ligated fistula between ...
