Intraaortic balloon counterpulsation.

The physiologic principle of hemodynamic circulatory support for the failing left ventricle must be directed toward reducing left ventricular work and myocardial oxygen demand and increasing myocardial oxygen supply. This support can best be accomplished with the use of intraaortic balloon counterpulsation. Support of the failing heart after cardiopulmonary bypass was the most frequent indication for counterpulsation treatment in our reported series. This type of assist was required in 5.2 percent of my patients. I reviewed the reports from three medical centers and added our own results in patients who required intraaortic balloon counterpulsation for weaning from cardiopulmonary bypass. Of a total of 399 patients, 255 or 73 percent were weaned off the balloon assist device and of this group, 239 or 60 percent were subsequently discharged from the hospital. Among patients who required intraaortic balloon counterpulsation for postoperative pump failure, 43 (70 percent) of 66 patients were weaned off the intraaortic balloon device, and 35 (53 percent) were later discharged from the hospital. A 24 percent survival rate occurred in patients with cardiogenic shock treated solely with counterpulsation; however, the survival rate increased to 52 percent when those patients subsequently received cardiac catheterization and appropriate surgical intervention.

Single right coronary artery: clinical and angiographic findings with surgical management.

Sudden death, myocardial infarction, and anginal syndrome have occurred in patients with single right coronary artery even in the absence of occlusive arteriosclerotic disease. We are reporting the case of a patient with this anomaly without concomitant arteriosclerotic involvement who was managed surgically. A 46-year-old woman was seen with disabling angina of 8 months' duration. Coronary arteriography established the diagnosis of a single right coronary artery. An aorta-anterior descending saphenous vein bypass graft was performed, and the patient remains asymptomatic 29 months postoperatively. Single right coronary artery is a rare anomaly, and its recognition as a potentially dangerous lesion is essential for the prompt and proper care of patients.

Technique for using soft, flexible catheter stents in aortocoronary vein bypass operations.

A technique using soft, flexible catheter stents in performing coronary vein bypass surgery is presented which makes small vessel anastomoses easy and assures accuracy of suture placement with clear identification of the vessel lumen and an anastomosis without stenosis. It provides an essentially bloodless field without having to cross-clamp the aorta. The technique has been used to our complete satisfaction in all patients since we first started vein bypass operations in 1970. A review of the last 205 elective aortocoronary bypass grafts in 100 consecutive patients using this technique reveals a mortality of only 1% and an operative and postoperative myocardial infarction rate of 5%. About half the patients had left ventricular dysfunction with elevated end-distolic pressures, and 68% had had previous myocardial infarctions. Seventy percent of the patients are at present asymptomatic, 24% are improved, and only 4% show no improvement over their preoperative status during follow-up of one to three and one-half years.

Aldosteronoma in a child with localization by adrenal vein aldosterone: collective review of the literature.

Hyperaldosteronism due to aldosteronoma is a rare but potentially curable form of pediatric hypertension. We have presented a patient who had symptoms of enuresis and fatigue, and in whom the diagnosis was suggested by low serum potassium and persistent hypertension. Diagnosis was confirmed by increased plasma and urinary aldosterone and decreased plasma renin. The tumor was localized with the aid of adrenal venography and catheterization, which showed greatly increased plasma aldosterone levels in the right adrenal vein. The pathologic findings were totally reversed by right adrenalectomy. The clinical picture and results following surgical removal of aldosterone-producing tumors in six children are reviewed.
