[The tricuspid valve in carcinoid cardiopathy: characteristic echocardiographic aspects].

Cardiac involvement is commonly seen in the carcinoid syndrome (C.S.).

Cross-sectional echocardiographic features of ruptured chordae tendineae.

Thirty-two patients with mitral regurgitation secondary to ruptured chordae tendineae were studied by cross-sectional echocardiography. Twenty of them subsequently underwent operation. Three signs are described.

Prolapse of the mitral valve in secundum atrial septal defect: a functional mechanism.

Prolapse of the mitral valve in patients with secundum atrial septal defect has been described angiographically and by two-dimensional echocardiography. It has been suggested that prolapse of the mitral valve in these patients is due to distortion of left ventricular shape and small left ventricular volume. To test this hypothesis 10 patients with unrepaired secundum atrial septal defect and 10 patients who had undergone repair of the defect were studied by two-dimensional echocardiography.

Prognosis of Fallot's tetralogy after palliative operations: 10-25 year follow-up.

The condition of 350 patients with Fallot's tetralogy (FT) who had palliative surgery (aortopulmonary shunt or transventricular valvotomy) was reviewed 10-25 years later: 136 patients (38%) are alive without any further operation, 106 (30%) have recovered completely, and 108 (31%) have died. Actuarial survival at 25 years of the patients who had palliation was 50% compared to 83% for the group who subsequently had complete correction. After the first five years the mortality rates became 5% per year.

Bedside evaluation of atrioventricular block with narrow QRS complexes: usefulness of carotid sinus massage and atropine administration.

Second-degree intra-His bundle block is frequently of type I (Wenckebach periods) or 2:1. In this situation, the surface electrocardiogram does not permit distinction between intranodal (atrioventricular [A-V] and subnodal (intra-His) block. This study examined the value of bedside carotid sinus massage and atropine administration in diagnosing the site of block from the standard electrocardiogram in subjects with chronic A-V block and narrow QRS complexes.

Open aortic valvotomy for congenital aortic stenosis. Late results.

Forty-nine consecutive patients, aged 2 to 28 years, were followed after open aortic valvotomy. Three late deaths occurred in relation to reoperation. Seventeen reoperations were performed 2 to 14 years after valvotomy for severe stenosis in 12 patients, aortic regurgitation in three patients, and aortic stenosis and regurgitation in two patients.

[Right atrial myxoma. Review of the literature and a case report].

On the basis of a personal observation and from a complete review of the existing literature, clinical and instrumental findings of right atrial myxoma are described. The clinical presentation appears to be rather characteristic. The presence of systemic symptoms, peripheral venous hypertension and/or right heart failure without apparent cause are a clue to the diagnosis especially in an adult woman.

[Paroxysmal ventricular tachycardia with retrograde Wenckebach block and reciprocal beats (author's transl)].

A case of recurrent paroxysmal ventricular tachycardia with retrograde Wenckebach block and reciprocal beats was studied with His bundle electrogram and right ventricular stimulation. Reentry was reproduced whenever retrograde ventriculo-atrial conduction time reached a critical value. Concealed reentry was also demonstrated and shown to be responsible for the dropped beats of the Wenckebach sequence.
