BACKGROUND The arterial switch operation has become the surgical approach of choice for d-transposition of the great arteries, but there is an increased awareness of adverse sequelae in some survivors. Long-term patency and normal function of the translocated coronary arteries must be achieved. It is reported that dependent of the prior coronary status, 3%(More)
OBJECTIVE Aorto-coronary bypass graft disease with its increasing clinical signification represents an unsolved problem in cardiological and heart surgery practice. Late occlusion of autologous saphenous vein grafts is due to medial and neointimal thickening secondary to migration and proliferation of smooth muscle cells (SMCs) and the subsequent formation(More)
The aim of this study was to test three injection protocols for contrast-enhanced magnetic resonance angiography (MRA) of the thoracic aorta with a standard-dose application. Ninety-three patients with a total of 118 examinations underwent MRA of the thoracic aorta at 1.5 T. There were three injection protocols: in 24 cases, no test bolus was performed and(More)
BACKGROUND Cardiac myxomas are the most frequently encountered benign intracardiac tumors, that, if left untreated, are inexorably progressive and potentially fatal. Patients with cardiac myxoma can be treated only by surgical removal. This study summarizes our experience over 22 years with these tumors. METHODS Fifty seven patients (M/F: 14/43, age: 57.9(More)
The aim of this study was to evaluate the incidence of postoperative pulmonary supravalvular stenosis in patients with d-TGA and to assess the rate of success or failure of balloon angioplasty. Out of 70 patients with d-TGA 67 patients underwent successful arterial switch operation. Twelve children developed severe supravalvular pulmonary stenosis with a(More)
BACKGROUND Survival after first-stage palliative Norwood operations for single ventricle with systemic outflow obstruction is mainly dependent on a balanced ratio of pulmonary blood flow to systemic blood flow. Here we report the clinical results using a modified technique that allows a controlled systemic-to-pulmonary shunt flow to prevent pulmonary(More)
BACKGROUND The aim of this study was to determine the outcome after surgical repair of aortic coarctation in adults, analysing its effect on arterial blood pressure. METHODS Twenty-five adults (9 women, 16 men), mean age 43.4 years (19 to 70 years), underwent aortic coarctation surgical repair. All patients suffered from preoperative hypertension. Mean(More)
PURPOSE For treatment of univentricular heart, the Fontan operation has been established as the definitive palliation. The current controversy is mainly based on the high incidence of arrhythmias after an intra-atrial lateral tunnel Fontan operation. METHODS From January 1995 until April 2002, 46 children underwent a Fontan-type operation with or without(More)
BACKGROUND There is ongoing discussion as to whether it is beneficial to avoid pulmonary sinus augmentation in the arterial switch operation. We report a single-surgeon series of mid-term results for direct pulmonary artery anastomosis during switch operation for transposition of the great arteries (TGA). METHODS This retrospective study includes 17(More)
OBJECTIVE Our objective was to evaluate the impact of different rapid MRI techniques for the assessment and follow-up of chronic aortic dissections. MATERIALS AND METHODS Fifty-three patients (41 postoperative Stanford type A, 12 type B dissections) were scanned at 1.5 T during a 3-year period. The study reviewed ECG-gated breath-hold black blood(More)
