Does Intraoperative Myocardial Biopsy Have Any Prognostic Value in Predicting Myocardial Protection After Congenital Cardiac Surgery
Does Intraoperative Myocardial Biopsy Have Any Prognostic Value in Predicting Myocardial Protection After Congenital Cardiac Surgery
Despite major advances in the technical aspects of surgical repair of congenital heart diseases, perioperative myocardial damage with low cardiac output remains the most common cause of morbidity and death after repair of congenital heart lesions.
Myocardial sample was obtained from the endocardial surface of the right ventricle and placed in formalin until examination under light microscopy for detection of myocyte cellular edema as a marker of ischemic changes.
