Presence of Intramyocardial Fat Tissue in the Right Atrium and Right Ventricle – Postmortem Human Analysis

Lymphoma of the Right Atrium and Ventricle.

Rupture of Right Sinus of Valsalva Aneurysm with Alternating Shunting into Right Atrium and Right Ventricle

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly that may be congenital or acquired. We report the case of a 29-year-old female who presented with a three-month history of exertional dyspnea. Cardiac auscultation revealed a grade III/VI continuous murmur along the right sternal border. Transthoracic echocardiography revealed alternating jet-flows into the right atrium (RA) and right v...

Partial right-sided congenital pericardial defect with herniation of right atrium and right ventricle.

In an unusual case of right-sided pericardial defect with herniation of the right atrium and right ventricle, cardiac blood pool isotope imaging is introduced as a new, noninvasive diagnostic procedure. Surgery which consisted of excision of right-sided pericardium relieved the chest pain which was the only symptom the patient had prior to surgery.

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...

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...
