[Coronarography-scintigraphy comparison of the effects of trinitrin-spray in 15 patients with coronary disease].

15 patients with coronary disease underwent a dual investigation, angiographic and scintigraphic, first without treatment and after administration of 0.8 mg of sub-lingual trinitrin-spray. The radiocinema angiography enables to explore variations of the coronary and stenosic diameter, the duration of the opacification (inverse of circulatory velocity) and the tonality of the network.

[Diastolic coronary prolapse in partial left pericardial agenesis].

A few rare cases of coronary artery stenosis and occlusion have been reported in partial left pericardial agenesis. The authors report a privileged observation of partial left pericardial agenesis associated with an atrial septal defect in which diastolic collapse of the left marginal artery was demonstrated; this chronology was confirmed by synchronous analysis. The peroperative findings may explain the pathogenesis of the coronary disease encountered in this type of malformation, providing a new diagnostic sign of partial left pericardial agenesis.

[Course and prognosis of primary hypertrophic cardiomyopathies].

33 patients with hypertrophic cardiomyopathy were followed for a mean duration of 48 months. 29 of them were reviewed; 6 had died, including 4 with a familial form belonging to two different families. No cases of sudden death were observed.
