[Contribution of two-dimensional echocardiography to the diagnosis of abnormalities of the left coronary artery originating in the trunk of the pulmonary artery].

The abnormal origin of the left coronary artery from the trunk of the pulmonary artery is rarely encountered, difficult to diagnose and has a severe prognosis because of the major risk of sudden death. The authors report the case of a 63 year-old male patient, presenting this anomaly which creates a true left-to-right shunt with myocardial ischemia secondary to the steal of coronary blood toward the pulmonary artery. The diagnosis is evoked by bidimensional cardiac sonography, pulsated and color Doppler, which permit to confirm the left-to-right shunt while this is confirmed by coronary angiography. The treatment is essentially surgical.

[Thrombopenia caused by pentosan polysulfate].

Two case-reports of thrombopenias induced by pentosane polysulfate (PSP) are reported. PSP may play a direct role in the genesis of the thrombopenia appearing between the 5th and 15th day of treatment, or a sensitizing role where the thrombopenia occurs quite rapidly following heparin treatment. The clinical complications are haematomas, arterial or venous thromboses and haemorrhages. The platelet aggregation test is always positive in the presence of PSP. The immunological origin is probable. Monitoring of the platelet count is recommanded with this treatment.

[Intraoperative evaluation of mitral valve reconstruction using two-dimensional contrast echocardiography].

20 patients who underwent reconstructive surgery for mitral regurgitation were peroperatively investigated by contrasted bidimensional echocardiography using intraventricular injection of 20 ml of physiologic saline. Before the valvuloplasty, the peroperative quantitation of mitral leakage was in all cases closely correlated with the data obtained preoperatively. After the mitral reparation, three groups of patients could be observed: group I (12 cases): absent or minimal regurgitation (0-+); group II (5 cases): moderate mitral regurgitation (++); group III (3 cases): marked regurgitation ( - +) necessitating an immediate ECC. In two cases it was possible to improve successfully the valvular function, in the third case valvular replacement was necessary. The correlation between the data of peroperative contrasted echography at one hand and the clinical examination and the postoperative paraclinical investigations on the other hand was excellent in all cases. Thus the contrasted bidimensional peroperative echocardiography represents a reliable method for predicting the immediate results of mitral reconstructive surgery.
