[Dynamic left ventricular obstruction associated with a pheochromocytoma reversible after tumor ablation].

The association of dynamic left ventricular outflow tract obstruction and pheochromocytoma is rare with only about fifteen previously reported cases in the literature. The association may be the result of chronic increased catecholamine secretion which induces intra-ventricular obstruction in a hypertrophied ventricle due to hypertension. The authors report a new case in which the intraventricular gradient on Doppler echocardiography was particularly high at 120 mmHg.

[Spontaneous regression of a false aneurysm of the ascending aorta following surgery for dissection].

We report the case of a 50-year-old man admitted to hospital for a type A aortic dissection. After conventional surgical repair, he was asymptomatic and underwent computed tomography imaging at 15 days, 3 and 6 months. The first CT scan showed a small perigraft circulating false aneurysm which totally disappeared on the last exam.

[Value of the early determination of plasma myoglobin level in the diagnosis of acute myocardial infarction].

Serum myoglobin (Mb) was assayed by immuno-nephelemetry or immuno-turbidimetry together with creatinine kinase activity (CK) by spectrophotometry in 290 consecutive patients admitted to hospital between January 1st and September 30th 1992 in three cardiology departments for chest pain suggesting myocardial infarction (MI). The measurements were made at admission (T0) and 90 minutes later (T90). On admission, patients were classified as certain MI (N = 62), possible MI (N = 107) or definitely not MI (N = 121) and, on discharge, as certain MI (N = 144) or definitely not MI (N = 146).

[Left ventricular dilatation after primary transmural anterior myocardial infarction. Influence of the percentage of akinesia on echocardiography].

The aim of this study was to determine whether the percentage of akinesia on echocardiography during the acute phase of transmural anterior myocardial infarction could predict secondary left ventricular dilatation. The study group comprised 24 patients (18 men and 6 women) with an average age of 59 years. The patients underwent two echocardiographic examinations, the first during the acute (< 72 hours) phase and the second, 6 months later.
