[Atresia of the aortic arch. A rare cause of asymmetrical arterial hypertension in adulthood].

History And Clinical Findings: A 58-year-old man, previously resident in Russia, was known since the age of 18 years to have arterial hypertension of unknown cause in only the right arm. A single syncope was the only previous symptom. On examination the pressure was 230/110 mmHg in the right arm, 150/100 mmHg in the left one.

[Coronary angiography with a 5F catheter after percutaneous puncture of the right brachial artery. Technique and experience in 70 patients].

Out of a total of 1640 consecutive left heart catheterizations, 70 (58 males and 12 females; mean age 56 +/- 8 years) were performed via the right brachial artery, in most instances because of occlusive disease of the arteries in the pelvic region. 5F catheters were then successfully used for both the coronary and left-ventricular angiographies. Noninvasive examinations after two days (Doppler ultrasound, oscillography at rest and on exercise, acral plethysmography and colour-coded duplex sonography) revealed small haematomas in the region of the arterial puncture in four and a haemodynamically insignificant fistula between brachial artery and vein in one patient but no aneurysm, stenosis or thrombosis at the puncture site.

Acute and long-term haemodynamic and neurohumoral response to nisoldipine vs captopril in patients with heart failure: a randomized double-blind study.

To study the haemodynamic and neurohumoral effects of nisoldipine (2 X 10 mg) vs captopril (3 X 25 mg), 24 patients with heart failure (New York Heart Association class II and III) due to coronary artery disease were treated in a randomized double-blind trial over 3 months. Both drugs were well tolerated. Clinical status was similarly improved in both groups, nisoldipine exerted an additional antiischaemic effect.

Role of transmitral blood flow velocity by Doppler echocardiography in the evaluation of coronary artery disease.

To determine the relation between presence and severity of coronary artery disease and diastolic filling abnormalities by Doppler echocardiography, recordings of transmitral inflow velocity were made at rest in 90 patients with coronary artery disease and 28 normals. At the time of the Doppler examination, 81 patients with coronary artery disease (90%) and 10 normals (36%) were treated with antianginal medications. No difference was found in the ratio between early (E) and late (A) diastolic filling velocity (E/A ratio) when comparing patients with greater than 70% obstruction of at least one coronary artery to age-matched normals, regardless of the presence or absence of wall motion abnormalities.
