Controlled Clinical TrialComplete preservation of the mitral valve apparatus during mitral valve replacement for rheumatic mitral regurgitation in patients with an enlarged left ventricular chamber.
The merits of retaining the subvalvular apparatus during mitral valve replacement (MVR) for chronic mitral regurgitation have been demonstrated in clinical investigations. This study was to investigate the feasibility of total preservation of the leaflet and subvalvular apparatus at the native anatomic position during MVR in a rheumatic population with enlarged left ventricular chamber. ⋯ This study shows that complete mitral leaflet preservation at the native anatomical position during MVR is feasible in rheumatic patients with an enlarged left ventricular chamber and confers significant short-term and long-term advantages by preserving left ventricular function and geometry. Therefore, it is a safe, simple, and effective surgical technique and should be individualized during clinical use.

Comparative StudyDecision making and results of coronary artery bypass grafting for patients with poor left ventricular function.
The aim of this study is to determine the results of coronary artery bypass surgery in patients with a low ejection fraction. Between January 2007 and January 2011, 3556 consecutive patients who underwent coronary artery bypass grafting at the Cardiovascular Surgery Clinic at Sifa University Hospital, Izmir, Turkey, were analyzed retrospectively. ⋯ Coronary artery bypass grafting can be safely performed in patients with low ejection fraction with minimal postoperative morbidity and mortality. The viable myocardium could be reliably determined by positron emission tomography. Low ejection fraction patients could greatly benefit from coronary bypass surgery regarding postoperative ejection fraction, increased long-term survival, improvement in New York Heart Association classification, and higher quality of life.

Case ReportsSimultaneous repair of a sinus of valsalva aneurysm and a bicuspid aortic valve.
Sinus of Valsalva aneurysms (SOVA) are rare cardiac abnormalities that are most commonly congenital in origin and frequently associated with aortic valve pathology. Unruptured SOVA are more frequently identified currently, owing to the increased use and accuracy of diagnostic investigations. Early surgical intervention is recommended to prevent complications. We describe a case of a young patient with an enlarging right SOVA and a regurgitant bicuspid aortic valve who subsequently underwent simultaneous patch repair of the SOVA and primary aortic valve repair.

Case ReportsUse of a totally artificial heart for a complex postinfarction ventricular septal defect.
The incidence of cardiac rupture complicating myocardial infarction has declined since the introduction of thrombolytic therapy. Despite the advances in the management of myocardial infarction, cardiac rupture remains an important cause of death among infarction-related fatalities. We discuss a patient who presented to our hospital with myocardial infarction and who subsequently developed a complex ventricular septal rupture, for which surgical repair was not feasible. Implantation of a CardioWest Total Artificial Heart (SynCardia Systems) allowed for immediate hemodynamic stabilization and served as a bridge to transplantation.

Experience with a minimally invasive approach to combined valve surgery and coronary artery bypass grafting through bilateral thoracotomies.
Minimally invasive coronary artery bypass grafting (MICS-CABG) and minimally invasive valve surgery (MIVS) have been used independently to manage occlusive coronary artery disease and valvular diseases, respectively. We present 12 patients who underwent combined MICS-CABG and MIVS via bilateral mini-thoracotomies. ⋯ MICS-CABG combined with MIVS via bilateral minithoracotomies yielded short-term results comparable to those for CABG and valve repair via median sternotomy. There were no operative mortalities or reoperations. The possible advantages of the minimally invasive approach included earlier extubation and earlier discharge from the hospital. Combined CABG and valve surgery can be safely performed via bilateral thoracotomies.
