ventricular arythmia

Pheochromocytoma is a rare tumor potentially life-threatening and associated with non specific and diverse symptomatology. Cardiac symptoms may mislead diagnosis; they could manifest as myocardial sideration concomitant to a hypertensive peak or supraventricular arythmia. We report a case of pheochromocytoma associated with hypokaliemia revealed by a myocardial ischemia with acute cardiac failure and severe left ventricular depression and complete reversal after surgery.

From 1973 to 1977, 93 infants (63 newborns) with d-TGA were treated with Blalock-Hanlon operation. All children had Rashkind atrioseptostomy at birth. 65 infants with isolated TGV were operated upon with two deaths (3%) and without any complication. 18 patients with TGV and VSD were treated with Blalock-Hanlon operation and Pulmonary Artery Banding and resulted in 5 deaths (28%). The other 10 cases had complex lesions. The overall operative mortality is 8.6%. The late mortality is 3.5%. The authors conclude that the Blalock-Hanlon operation is a safe procedure even in complex lesions...

The authors report the case of a 77 year old man suffering from chronic congestive heart failure, who presented a severe hepatic failure. Since 9 days the patient was treated by cibenzoline for serious ventricular arythmias. Hepatic failure was not due to drug hepatotoxicity but to an indirect effect of cibenzoline diminishing cardiac output. Arguments for ischaemic hepatitis and also two mechanisms of hepatic involvement in cardiac diseases are developed. In most cases association of two mechanisms, vascular stasis and low cardiac output is necessary to create hypoxic hepatitis...

Seventeen of 27 patients studied before and after surgical operations for basal meningioma frequently showed forms of cardial sinusal arythmia, sinusal tachycardia and ventricular extrasystolia. These pathological changes in cardiac rhythmics appeared and were aggravated during the postoperational period. Their possible pathophysiological mechanisms, due to the effect of the tumor and operative injury to the hypothalamo-diencephalic apparatus are discussed.

As revealed by a very thorough cardiological study of Steinert's disease in 13 cases, it would appear that the incidence of cardiac involvement observed in this disease is not merely frequent; it is, in fact, usual, systematic, and forms an integral part of the pathological picture in the same way as peripheral muscular dystrophy. One is aware of the diagnostic interest of this fact in the juvenile or abortive forms of the disease. The cardiac involvement is an indication of the complete expression of the gene towards striated muscle tissue, whether skeletal or myocardial...
