[Open mitral commissurotomy. Indications and results].

We have reviewed the clinical history of 106 patients that were done an open mitral commissurotomy from june 1971 to march 1974. Hospital mortality was less than 1% and morbility was low. The patients average age was 40 years. Fifteen patients had suffered a previous closed mitral commissurotomy, and systemic embolism occurred in 62.2% of them. Ninety eight of the surviving patients have been followed; 80.6% of them had improved by at least one degree of the N.Y.H.A. functional scale. According to these results we have widened the indications for open mitral commissurotomy. However, we still use the closed technique in young patients without previous mitrol commissurotomy or past history of system embolism, which no fluoroscopic evidence of mitral valve calcifications and without associated valvular lesions.

Anoxic cardiac arrest: Its effect on myocardial mitochondrial metabolism.

Forty eight healthy dogs are subjects to cardiopulmonary bypass and divide into two groups according to whether the perfusion is performed in normothermia or moderate hypothermia (30 degrees C). The effects on oxidative phosphorylation and mitochondrial respiration, produced by increasing periods of myocardial anoxia from aortic cross clamping, are studied. A clear correlation is found between the disturbances of mitochondrial metabolism and the future cardiac recovery. Hypothermia shows a protective effect on the anoxic myocardium. It is concluded that the period of absolute safety in cardiac anoxia, as far as mitochondrial function is concerned, is 15 minutes in normal thermic perfusion and 90 minutes in moderately hypothermic ones.

Counterpulsation in experimental cardiogenic shock with ventricular arrhythmias. The antiarrhythmic effect of morphine.

In two groups of dogs a cardiogenic shock was induced and their circulation assisted by counterpulsation. In the second group aside from the counterpulsation, 4 mgrs/Kg of morphine was administered when stable ventricular arrhythmias appeared. Morphine showed to eliminate the ventricular arrhythmias in three cases and lessened them considerably in one, permitting better assistance with a counterpulsator.

Traumatic ventricular septal defect: a case of early repair and review of the literature.

We present a case of traumatic ventricular septal defect following a stab wound of the heart. The patient was operated on within the first 24 hours after being injured, because the hemodynamic situation had deteriorated; he is well 31 months postoperatively. From the literature reviewed, it is apparent that most of such lesions should be corrected early, since these patients are exposed to the continued risk of symptomatic cardiac dysfunction, and repair offers an excellent prognosis with minimal morbidity.

Combined transplantation of heart and liver from two different donors in a patient with familial type IIa hypercholesterolemia.

A 12-year-old child with terminal ischemic heart disease as a result of homozygotous familial type IIa hypercholesterolemia received an orthotopic heart transplant and, 21 days later, an orthotopic liver transplant. Six months after heart transplantation, the patient is asymptomatic and evidences normal liver function and cholesterol levels; there are no signs of heart rejection. To our knowledge, this is the first instance of two-step heart-liver transplantation with organs from different donors.
