[Atherosclerotic coronary ectasia or a lymphomucocutaneous syndrome in an adult (Kawasaki's disease)?].

We report the case of a 42-year-old man, who was admitted to hospital with an inferior myocardial infarction. He was treated with tissue plasminogen activator without complications in the acute phase. The stress testing performed before discharge showed residual myocardial ischemia.

[Thrombus in the thoracic aorta as cause of peripheral embolism diagnosed using transesophageal echocardiography].

The authors report the cases of two patients, with no risk factors for thromboembolism, in whom a mobile thrombus of the thoracic aorta was diagnosed by transesophageal echocardiography, after an episode of systemic embolism. The outcomes of the two cases were very different. In one patient the thrombus was no longer present after anticoagulant treatment with no recurrent embolic event.

[The effect of antihypertensive therapy on left ventricular mass and diastolic filling in light and moderate hypertension].

Background: To valorate the effect of four antihypertensive drugs on the regression of cardiac mass and diastolic function, by echocardiography-Doppler, in not treated hypertensive subjects.

Methods: 60 mild-moderate hypertensive subjects were studied randomized in four groups of 15 patients each one: enalapril (10-40 mg/d), atenolol (25-100 mg/d), verapamil-retard (120-240 mg/d), alphametildopa (250 mg/8h to 3 g/d). The active drug therapy phase was 6 months, performing echo-Doppler, evaluating posterior-wall and septal-wall thicknesses, ventricular mass index, ratio of early to atrial peak diastolic filling velocity (E/A), the first-third filling fraction and atrial filling fraction.

[The 2-dimensional and Doppler color echocardiographic study of a congenital aneurysm of the sinus of Valsalva with a fistula of the right atrium in an adult].

This report describe a 69-year old woman with a congenital aneurysm of the non-coronary sinus of Valsalva ruptured in the right atrium, causing severe hemodynamic derangement of the right ventricle. The site of the communication between the aneurysm and the receiving chamber was accurately diagnosed by two-dimensional color flow Doppler imaging which provided more valuable preoperative information than conventional aortography.

[Doppler analysis of mitral flow in mild to moderate hypertension].

We evaluate by Echo-Doppler the left ventricular relaxation disturbance produced by mild to moderate hypertension. It's a comparative study between 15 healthy and 40 patients with hypertension (diastolic blood pressure between 90-114 mmHg and/or systolic greater than 160 mmHg). Echocardiography was performed in all cases and diameters, thickness, volumes, ejection fraction, mass, transmitral flow by Doppler and cardiac output were evaluated .
