Comparative effects of atenolol and clonidine on polygraphically recorded sleep in hypertensive men: a randomized, double-blind, crossover study.

The effects on sleep of atenolol and clonidine were compared in 8 hypertensive men (mean age 46.9 years, range 16-56 years) without prior history of sleep disturbances. Polygraphic sleep recordings were performed at baseline (NO) and after a single oral dose of atenolol (100 mg) or clonidine (0.

[Value of mazindol in Gélineau's disease. Apropos of 10 cases].

Ten narcoleptic patients were treated daily with Mazindol 2-6 mg for 42.2 months (31-63 months). The response was excellent on narcoleptic attacks in 6 and on cataplexy in 7 cases.

Remote skin injury: a protean complication of open heart surgery.

In the 12-month period ending August, 1984, 14 adult patients (2.9%) developed within 24 hr following open heart surgery skin defects of varying magnitude remote from the incision site. Electrical injury secondary to a grounding defect was documented in two patients and suspected in one.

Exercise tests in patients with severe angina pectoris: an angiographic correlation.

Graded submaximal ergometric tests were peformed on 60 patients who suffered from clinically severe angina pectoris, and the results were correlated with their coronary angiograms. The test was positive in 44, negative in 9, and undetermined in 7 patients (defined as failure to reach the target heart rate without ischemic ST changes). Among patients with positive tests, 42 (95%) had obstruction of one to three coronary vessels.

"Coronary" T waves in the presence of complete left bundle-branch block: a normal variant?

The case report of a patient with an ECG pattern of intermittent left bundle-branch block, presenting inverted and symmetric ("coronary") T waves in leads V1 to V3 during periods of normal intraventricular conduction, is presented. The patient was followed up for eight years during which time no relevant symptoms appeared while extensive noninvasive investigations repeatedly failed to reveal any organic basis for the ECG changes. It is stressed that inverted, symmetric T waves in right-sided chest leads may be encountered in young, otherwise healthy subjects with intermittent left bundle-branch block during periods of normal intraventricular conduction.

Chordal rupture: a common complication of myxomatous degeneration of the mitral valve.

In two patients with a clinical picture of acute mitral insufficiency, the presence of chordal rupture secondary to myxomatous degeneration of the mitral valve was disclosed during surgery. There was no evidence of previous rheumatic valvulitis, subacute bacterial endocarditis or other etiologies. It appears from the literature and from the cases described that ruptured chorda tendinea is a not uncommon complication of myxomatous transformation of the mitral valve.

False aneurysm of the left atrium after closed mitral commissurotomy: diagnosis by cineangiocardiogrpahy. Report of one case treated surgically.

A case of false aneurysm of the left atrium after closed mitral commissurotomy which was demonstrated by cineangiography is here reported. It is believed that the false aneurysm resulted from a tear of the left appendage which accidentally occurred during the surgical procedure. The diagnosis was suspected in plain chest X-ray and fluoroscopy.

Left ventricular aneurysmectomy for refractory tachyarrhythmias: report in 11 postinfarction patients.

Between January 1970 and August 1974, eleven postinfarction patients underwent left ventricular aneurysmectomy for refractory tachyarrhythmias. Ten suffered from ventricular tachycardias and one from supraventricular tachycardia. All had localized aneurysms and normal contractions of the surrounding myocardium on angiocardiography.

Nonrheumatic mitral incompetence.

This review clearly indicates that a clinical picture of pure, isolated mitral insufficiency constitutes an interesting diagnostic challenge. In adult patients especially, this common valvular lesion is often nonrheumatic and may be found in a variety of cardiac conditions. The following provides a general orientation for their differential diagnosis.

Telangiectatic fistula between the conal branch of the left coronary artery and the pulmonary trunk.

A rare case of telangiectatic communication between the conal branch of the left coronary artery and the pulmonary trunk in a 50-year-old woman is reported. Unusual features included the presence of clear-cut angina on effort, unstable auscultatory findings and a RSR' pattern in lead V1, probably related to concommitant diffuse coronary atherosclerosis. Ten previously reported cases of the condition are briefly reviewed.

Multiple anomalous venous systemic connections in a case of atrial septal defect associated with right aortic arch and spine defromities.

Multiple anomalies of persistent left superior vena cava and left hepatic vein emptying into the left atrium associated with atrial septal defect, right aortic arch and multiple skeletal malformations are presented. The anatomy and the embryology of these anomalous venous connections are briefly reviewed. Clinical, hemodynamic and surgical implications of these anomalies are discussed.
