Retrograde ilioaortic dissection: A complication of common femoral artery perfusion during open heart surgery

Summary Retrograde ilioaortic dissection was recognized at surgery in 3 per cent of 378 patients forty years old or more undergoing open heart procedures with femoral arterial perfusion. Treatment of this complication was inadequate. Therefore, to prevent this complication of open heart surgery, the site of arterial cannulation was changed from the femoral artery to the ascending aorta. Subsequently 197 patients, of whom eighty-eight were forty years old or more, have been operated upon without occurrence of this complication.

The electrical impedance cardiogram in health and disease

Abstract 1. 1. The electrical impedance cardiogram (ICG) records continuous changes in heart shape throughout the cardiac cycle. It can be recorded on any direct writing electrocardiograph. 2. 2. Certain electrical impedance cardiograms closely resembled mechanical displacement recordings of heart motion (apexcardiograms), indicating a related origin. 3. 3. Tracings from normal subjects resembled each other, but tracings from patients with known cardiac deformities differed from the normal. 4. 4. Atrial activity was recorded selectively. 5. 5. Paradoxical bulges of the left ventricle produced characteristic abnormalities in impedance cardiograms. 6. 6. The impedance cardiogram can be used to analyze dynamic dysfunctions of the heart.

Surgical Treatment of High Pressure Patent Ductus Arteriosus

Thirteen patients with high pressure patent ductus arteriosus were operated upon. There was no operative mortality in this group. Twelve patients have shown remarkable clinical improvement, and there was a decrease in the pulmonary arterial pressure at the time of recatheterization in 11 of these patients restudied. One patient developed severe pulmonary hypertension and died six and one-half years after operation.The pulmonary arterial systolic pressure dropped minimally in two patients, despite marked clinical improvement. Both patients had associated lesions: a large ventricular septal defect in one and severe congenital aortic stenosis in the other. Both patients are to be operated upon.All patients with a predominant left-to-right shunt and a patent ductus arteriosus should have division of the patent ductus arteriosus. If a concomitant lesion requiring open-heart operation, such as a ventricular septal defect or aortic stenosis, is present, it should be corrected at a later date.

The Surgical Treatment of Mitral Insufficiency Associated with Torn Chordae Tendineae

In 1963 Kay and Egerton 1 and in 1965 Kay, Tsuji, and Redington2 reported on the surgical treatment of mitral insufficiency associated with torn chordae tendineae.
