The diagnosis of ruptured aortic cusp leading to acute aortic insufficiency was made by echophonocardiographic techniques in a patient with non-vegetative aortic valvular endocarditis and a negative clinical history. Early closure of the mitral valve, weak first heart sound, tall A wave of apexcardiogram. and early diastolic murmur indicated acute aortic regurgitation. Fine high frequency echoes of the aortic root and aortic leaflets suggested ruptured aortic leaflet unlike that reported in the presence of vegetations. Timing of S1 in acute aortic regurgitation by phonocardiogram, echocardiogram, and pulse techniques could not establish a single causative valvular relation in the genesis of this sound.

    Takayasu's aortitis is rare in male patients. The authors describe the case of a 48-year-old man with a fever of unknown origin, progressive general fatigue, and dyspnea due to aortic regurgitation. A severely thickened aorta was noted during aortic valve replacement. The diagnosis was based on...

    A 7-month-old boy with aortico-left ventricular tunnel arising from the right coronary sinus underwent surgical correction using the two patch technique. The diagnosis was confirmed by 2-D and Doppler echocardiogram alone. Patch closure of both the aortic and ventricular ends of the tunnel is...

    The author examines the utility of transcatheter closure (TCC) as an alternative to surgery of patients with ruptured sinus of Valsalva aneurysm (RSOV). ROSV is a rare clinical entity that is invariably a form of left-to-right shunt because of rupure into right-sided chambers. The criteria for...

    : Aortic insufficiency, myocardial fibrosis and conduction disturbances are known complications of ankylosing spondylitis (AS). However, few studies have assessed left ventricular diastolic function and no data are available about P-wave analysis. In this study 88 AS patients and 31 healthy...
