LEFT-VENTRICULAR CONTRACILITY AFTER HYPOTHERMIC PRESERVATION - PREDICTIVE VALUE OF P-31 - NUCLEAR-MAGNETIC-RESONANCE SPECTROSCOPY

International audience; Abstract: Early graft failure accounts for a substantial portion of the mortality after heart transplantation. This factor underscores the need for the development of reliable methods for predicting graft performance and thus ensuring optimal clinical outcome. The aim of this study was to describe the link between myocardial metabolism evaluated throughout preservation with the use of phosphorus 31-nuclear magnetic resonance spectroscopy and ventricular contractility after reperfusion. Thirteen pig hearts were excised and preserved from 3 to 12 hours with clinical techniques. During preservation the hearts underwent, phosphorus 31-nuclear magnetic resonance spectrosc…
