First derivative of intraventricular pressures in complete transposition of great vessels.

First derivative of intraventricular pressures in complete transposition of great vessels.

The first derivative of intraventricular pressure (dp/dt) reflects the rate of development of tension in the myocardium and has been employed as an index of contractility. The peak dp/dt of left ventricular (LV) pressure in the normal heart is higher than the right ventricular (RV) peak dp/dt. It is not known whether this is related to the basic difference in the architecture of the ventricular...

Acid-base balance in complete transposition of the great vessels.

In complete transposition of the great vessels the pulmonary and systemic circulations exist as two separate circuits. Although the pulmonary and the systemic blood flows may vary widely, the effective pulmonary blood flow is often small (Shaher, 1964). While the acid-base balance in the systemic circuit has been studied by several workers (Sunico, Harned, and Ordway, 1960; Gootman, Scarpelli, ...

The Coronary Circulation in Complete Transposition of the Great Vessels.

While the anatomy of the coronary arteries in complete transposition of the great vessels has been studied by several authors, the overall problem of adequacy of the coronary blood supply in this condition has received less attention. Spitzer (1923) described the probable embryological basis for partial or complete transposition of the coronary arteries. Astley and Parsons (1952) thought that m...
