Local deep hypothermia for combined valvular and coronary heart disease
DF Pupello, RH Blank, LN Bessone, RG Connar and LM Carlton Jr
Local deep hypothermia was utilized as the sole method of myocardial
protection in 113 consecutive aortic valve replacements. Thirty-six
patients had simultaneous revascularization, mitral valve replacement,
tricuspid valve replacement, or a combination of these. In follow-up for as
long as 36 months there have been 3 hospital deaths (2.6%), all occurring
in the group having isolated aortic valve replacement. No hospital deaths
occurred among patients undergoing a combined procedure.
