OBJECTIVES Different surgical techniques for the treatment of complex transposition of the great arteries (TGA) with ventricular septal defect and left ventricular outflow tract obstruction (LVOTO) have been developed, in particular the Rastelli operation, the réparation à l'étage ventriculaire procedure and the Nikaidoh procedure. The hitherto published results of the Nikaidoh procedure and it...

BACKGROUND Population-based studies have provided insight into the natural history of adult hypertrophic cardiomyopathy, but comparable information for affected children is lacking. METHODS AND RESULTS All Australian children who presented with primary cardiomyopathy at 0 to 10 years of age between January 1, 1987, and December 31, 1996, were enrolled in a longitudinal cohort study. A single ...

THE anatomic sites at which obstruction to the egress of blood from the left ventricle may occur are three in number, as follows (fig. 1): the aorta, the aortic valve, and the subaortic region of the left ventricle. Obstruction in the aorta may involve one of two general areas, namely, (1) the arch or just beyond, the lesions taking the forms of classical coarctation, tubular hypoplasia, or int...

We report an unusual case of a 32-year old man who was treated for a hypertrophic obstructive cardiomyopathy (HOCM) with a DDD pacing with short AV delay reduction in the past. Without prior notice the patient developed ventricular fibrillation and an invasive cardiac diagnostic was performed, which revealed a myocardial bridging around of the left anterior descending artery (LAD). We suspected...

THE PURPOSE of this paper is to summarize the clinical, hemodynamic, and angiographic aspects of valvular, subvalvular, and supravalvular aortic stenosis, with emphasis upon recognition of the more severe grades of the diseases that may require operation. A basic feature of obstruction to left ventricular outflow is the need for the ventricle to produce high systolic pressure; a systolic pressu...

A 96-year-old woman developed hemiparesis 2 weeks after orthopedic surgery. Magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral hemisphere. Transthoracic echocardiography revealed a mobile structure attached to the anterior mitral leaflet that protruded toward the left ventricular outflow tract. The structure was identified as an accessory mitral valve. Doppler ec...

INTRODUCTION AND OBJECTIVES Dynamic left intraventricular outflow tract obstruction occurs occasionally in patients without hypertrophic cardiomyopathy. We hypothesized that dynamic intraventricular obstruction might occur during effort in patients with angina or dyspnea without evident disease. The objective of this prospective study was to investigate: a) whether it appears with effort; b) it...

Rev Esp Cardiol 2004;57(12):1179-87 1179 Introduction and objectives. Dynamic left intraventricular outflow tract obstruction occurs occasionally in patients without hypertrophic cardiomyopathy. We hypothesized that dynamic intraventricular obstruction might occur during effort in patients with angina or dyspnea without evident disease. The objective of this prospective study was to investigate...

I t is not unusual for complicated aneurysms of the ascending aorta to affect left ventricular function. Processes causing or associated with an aneurysm may narrow the coronary artery ostia and produce myocardial ischemia or infarction; the aneurysm may distort the aortic valve ring and produce aortic insufficiency with subsequent left ventricular hypertrophy, dilatation, and failure. However,...
