We present the case of a 22-year-old man with a congenital mixed aortic valve dysfunction who underwent cardiac Magnetic Resonance Imaging (MRI) for the assessment of aortic valve morphology and function prior to valve replacement. Cardiac MRI showed a four-leaf-clover aortic valve morphology, the typical presentation of a quadricuspid aortic valve. The patient underwent a successful Bentall pr...

Background: Mitral valve disease is the most common acquired heart disease in dogs. Mitral valve regurgitation (MR) due to endocardiosis is an important cause of morbidity and mortality in dog. Echocardiography as a non-invasive tool is routinely used to evaluate and diagnose different disorders in the heart. Objectives: The purpose of this study is to determine the efficacy of medical treatmen...

We developed and validated a mitral valve orifice method for Doppler cardiac output determination. In 15 open-chest dogs, cardiac output was controlled and measured by a roller pump interposed between the right atrium and pulmonary artery as a right-heart bypass. Left heart flows were measured in the open-chest dog model by Doppler measurements at the mitral valve orifice and compared not only ...

All patients undergoing heart surgery experience a certain amount of nonspecific myocardial injury documented by the release of cardiac biomarkers and associated with poor outcome. We investigated the role of unipolar radiofrequency ablation of atrial fibrillation on the release of cardiac biomarkers in 71 patients undergoing mitral valve surgery and concomitant left atrial ablation case-matche...

cardiac hydatid cyst (chc) is a rare disease that was endemic in some regions especially in sheep-raising areas. the most commonly accepted theory for the routes of heart involvement in hydatid cyst was infestation by the hexacanthus embryo through coronary arteries. here, we describe a case with the primitive cardiac hydatid cyst located around the pulmonary valve (pv) and main pulmonary arter...

BACKGROUND Mitral valve repair is considered better than mitral valve replacement for degenerative mitral regurgitation. AIM To evaluate late clinical results of mitral valve repair as compared to mitral valve replacement in patients with degenerative mitral regurgitation. PATIENTS AND METHODS All patients subjected to open heart surgery for degenerative mitral regurgitation between 1990 an...

there is a paucity of literature regarding iatrogenic aortic valve perforation after cardiac operation is performed in the vicinity of the aortic valve. this report describes the clinical, echocardiographic, and angiocardiographic recognition of iatrogenic aortic valve perforation in a patient who had previously under gone membranous ventricular septal defect and pulmonary stenosis. five days a...

PURPOSE Acute pancreatitis is one of the potentially lethal complications that occurs after cardiac surgery. We tried to identify risk factors for and the prognosis of acute pancreatitis after cardiac valve surgery with cardiopulmonary bypass. MATERIALS AND METHODS We retrospectively analyzed a database of consecutive patients who underwent cardiac valve surgery with cardiopulmonary bypass be...

The purpose of a prosthetic cardiac valve is to restore the function of a diseased aortic or mitral valve, and its role in haemodynamics is a passive one: the opening and closing of such a valve is strictly regulated by the pressure differences in the cardiac chambers which communicate through this valve. Therefore we consider that a prosthetic valve should be tested under conditions simulating...
