Fluorine 18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Cardiac Viability Risk Stratification in Comparison with EuroSCORE II for Revascularization in Patients with Left Ventricular Dysfunction.

Background: Diagnostic value of fluorine 18-fluorodeoxyglucose positron emission tomography/computed tomography (F18-FDG PET/CT) in the assessment of myocardial viable segments is well known; hence, it can identify patients with left ventricular (LV) systolic dysfunction who may benefit from revascularization. The presence of significant myocardial viable segments before revascularization will offer better prognosis with reduced mortality and morbidity. However, the usage of F18-FDG PET/CT myocardial viability study in the presurgical risk stratification is limited.

Mitral valve replacement in the young patient with rheumatic heart disease. Early and late results in 118 subjects.

During a 14 year period, 118 young patients between 9 and 20 years of age underwent mitral valve replacement. In view of the acknowledged advantage of durability and minimal thrombogenicity, we chose the Starr-Edwards valve prosthesis in the large majority of our subjects. Other prostheses have also been used.

Results of surgical treatment of ventricular septal defects with pulmonary hypertension.

Two hundred and twenty-five consecutive patients with interventricular septal defect and associated pulmonary hypertension have undergone corrective surgery at the Christian Medical College Hospital. The mean preoperative systolic pulmonary artery pressure was 70.5 (range 31-136) mm Hg and the calculated pulmonary vascular resistance ranged from 300 to 1680 dyn/s cm-5.
