Strict temperature control ≤15°C may protect hypertrophied myocardium across solutions in AVR; leaves open tailored strategies for severe LVH.
Do different cardioplegic solutions adequately protect hypertrophied myocardium when regional temperature is kept ≤15°C in patients undergoing aortic valve replacement?
Maintaining regional myocardial temperature below 15°C during cardioplegic arrest adequately protects hypertrophied hearts regardless of the cardioplegic solution used, though severe hypertrophy may still limit protection.
