Right atrial scars participating in macro reentrant tachycardia circuits are generally seen in patients following cardiac surgery for congenital heart disease. Right and left atrial scars without any prior cardiac surgery have been reported but are rare [1,2]. A 65 year old farmer had recurrent drug refractory atrial tachycardia for which he underwent an EP study with three dimensional mapping ...

abstract hypoplastic right ventricular is a rare congenital heart disease. a few cases have been reported. we presented a case with hypoplastic right ventricular and multiple associated anomaly (ventricular septal defect, atrial septal defect and pulmonary stenosis) in whom the main concern was whether biventricular repair or fontan type surgery would be the optimal management in this patient. ...

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 ...

background rheumatismal mitral stenosis is less common today than it was several decades ago, but it is a common cause of mitral stenosis (ms) in the developing world. mitral valve stenosis symptoms include fatigue, palpitations, and shortness of breath especially with exertion. objectives the purpose of this prospective study was to determine the incidence of left atrial (la) thrombus and the ...

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...
