Angiotensin II (AII) has been implicated as an important factor in the pathophysiology of heart diseases. Following the recent identification of two subtypes of the AII receptor in cardiac tissue of animals, we investigated the possible occurrence of these, or similar, subtypes in human atrial tissue. In right-atrial tissue from patients undergoing heart surgery, we determined the AII-receptor ...

Abstract Aims patients with severe aortic stenosis (AS) experience an increase in left ventricular filling pressure. This leads to changes the structure and a deterioration function of (LA) right (RA) atrium. Patients undergoing TAVI usually reduction pressure ventricle, thereby decreasing wall tension atria retrograde way. The aim this study was demonstrate that AS, TAVI, positive remodeling a...

A 70-year-old man with paroxysmal atrial fibrillation was referred for pulmonary vein isolation. Past medical history included ischemic heart disease and a right hemicolectomy for Duke’s C carcinoma 10 years previously. Presenting ECG showed sinus rhythm with a normal axis and evidence of left atrial enlargement (Figure 1). Preoperative echocardiography demonstrated normal left ventricular stru...

The interatrial pressure-flow dynamics in patients with right-to-left shunting at the atrial level in the presence of right heart obstruction were studied. In tricuspid atresia most of the right-to-left gradient occurred during right atrial systole. This gradient, as well as the cineangiocardiograms, indicated that almost all systemic venous return was transferred from the right to the left atr...
