[Silent aortic insufficiency mimicking dilated cardiomyopathy].

The authors report 6 cases of severe and silent aortic insufficiency having simulated in all aspects the picture of a dilated cardiomyopathy at the stage of cardiac insufficiency with primary manifestations. They insist on signs leading to the diagnosis of this clinical entity: past history of rheumatism, signs of electrical left ventricular hypertrophy in the absence of arterial hypertension, aortic calcifications and mostly presence of a discrete mitral diastolic fluttering during echocardiographic examination. Supra-sigmoid aortic angiography confirms the diagnosis of severe aortic regurgitation. In order to explain the non-perception of the murmur, they invoke the alteration of the transmission secondary to an air cushion (3 cases the association of another valvulopathy with murmur (1 case) and mainly the decrease of the leakage by increase of the left ventricular telediastolic pressure and the decrease of the diastolic aortic pressure, with diminution of the turbulences. The advantage of knowing this entity rests on the possibility of valve replacement, even at the stage of myocardial failure, since the satisfactory long-term post-operative evolution in 4 patients stands in contrast with the dangerous nature of a spontaneous evolution.

The ergometrine test: effects on esophageal motility in patients with chest pain and normal coronary arteries.

Ergometrine can evoke coronary spasm in patients with variant angina. The cause of ergometrine-induced chest pain in the absence of coronary spasm is not clear. To determine whether ergometrine produced esophageal dysfunction and chest pain, we evaluated 28 patients by esophageal manometry. Six had chest pain in response to ergometrine during cardiac catheterization (group I) and 22 did not (group II). Results of cardiac catheterization were normal in all patients. Seven volunteers with no history of chest pain formed a control group (group III). Esophageal manometry was performed before and after ergometrine administration (0.4 mg I.V.). Ergometrine provocation during esophageal manometry caused significant deterioration in esophageal motility associated with familiar pain in 5/6 group 1 patients. The motility disorders were characterized by repetitive contracts of high amplitude and long duration in the distal esophagus. No patient from group II or III experienced chest pain after ergometrine and only 2 from group II developed long duration contractions. Thus, we conclude that in patients with normal coronary angiograms, ergometrine-induced chest pain without associated coronary spasm suggests that esophageal motility disorders originate chest pain.

[Congenital agenesis of the inferior vena cava. Apropos of a case presenting as an ilio-femoral phlebitis. Contribution of echography and x-ray computed tomography].

The authors report the case of a young patient, 24 years old, hospitalized for a phlebitis of the right inferior member. The cause determined by venous angiography, echography and computed tomography, was a congenital agenesis of the inferior vena cava. This case allows to remember the embryology of the congenital anomalous inferior vena cava, which are rare and often unknown.

[Evaluation of the severity of coronary disease by thallium 201 myocardial scintigraphy and technetium 99m isotope ventriculography. Comparison of the 2 methods apropos of 30 cases].

The evaluation of the severity of coronary artery disease by non-invasive methods may involve the use of isotope techniques. The authors compared the results of technetium 99m cardiac functional angioscintigraphy and thallium 201 myocardial scintigraphy, performed at rest and on effort, in a group of 30 patients. The 30 patients consisted of 6 normal patients (control group) and 24 patients with coronary artery disease (8 cases of angina; 16 infarcts, including 12 inferior infarcts). Coronary angiography revealed 13 cases of one vessel disease, 8 cases of two vessel disease and 3 cases of three vessel disease. The results of angioscintigraphy revealed that the technique was reliable in terms of the evaluation of the abnormalities of contraction (sensitivity: 96%, compared with the results of haemodynamics) and that the study of the ejection fractions at rest and on effort was particularly valuable. The ejection fractions calculated by the isotope method were not statistically different from the ejection fractions calculated by the haemodynamic method. The patients with one vessel disease and the normal subjects increased their ejection fraction on effort by about 12% (p = 0.03), in contrast with the patients with multiple vessel disease, who increased their ejection fraction on effort by 2% (p greater than 0.05). In contrast, the results of myocardial scintigraphy at rest and on effort were disappointing. The method was specific (100%), but in our series, its sensitivity was only 72% for the group of patients with coronary artery disease. In cases with infarction and multiple vessel disease, the zone of the infarction was always detected, but no other abnormalities were observed in the other territories.(ABSTRACT TRUNCATED AT 250 WORDS)
