Calcification of the cardiac chambers is among the challenges associated with reoperative cardiac surgeries by increasing the risk of systemic embolization. We experienced a case of an unexpected detected mass by intraoperative transesophageal echocardiography during weaning from cardiopulmonary bypass in a patient undergoing trido mitral and tricuspid valve replacement surgery. The surgically ...

patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...

Assessment of Machine Learning Approaches to Predict in-Hospital Mortality in Patients Underwent Prosthetic Heart Valve Replacement Surgery

We present a technique for replacement of the aortic valve in selected patients undergoing redo surgery in the presence of patent coronary artery bypass grafts and occluded native coronary arteries that affords optimal myocardial protection, limited dissection of the heart and minimal risk of injury to existing grafts, in particular, the internal mammary artery.

OBJECTIVE Cardiac surgical mortality has improved during the last decade despite the aging of the population. An integrated US health plan developed a heart valve registry to track outcomes and complications of heart valve operations. This database was used for longitudinal evaluation of mitral valve (MV) outcomes from 1999 to 2008 at four affiliated hospitals. METHODS We identified 3130 pati...

j-Ieart size was measured radiographically before and after single or double homograft valve replacement in 69 consecutive patients. Thirty patients had aortic valve replacement, 25 mitral, and 14 both aortic and mitral valve replacement. For aortic valve replacement a fresh unsupported homograft was inserted in the subcoronary position, while for mitral valve replacement afresh semilunar homog...

OBJECTIVE Cardioplegic arrest and subsequent reperfusion results in myocardial injury partly related to local inflammation in the heart. It has been proven that aminophylline has numerous anti-inflammatory effects. This study has been designed to evaluate the effects of aminophylline used as a cardioprotective agent for patients undergoing cardiopulmonary bypass (CPB) for valve replacement. M...

Background EuroSCORE has been proposed to identify patients at high risk for surgical aortic valve replacement and estimate for them the risk-benefit of percutaneous implantation. However, it has been clearly demonstrated that this system overestimates mortality, particularly in the elderly population undergoing surgery for aortic valve replacement. An actualized model called EuroSCORE II has b...
