ABSTRACT

Objective To introduce the technique of mitral v alve replacements in beating heart, and review the clinical experience in 234 ca ses of operation. Methods A total of 234 patients of mitral val ve replacement in beating heart with mild hypothermic extracorporeal circulation (30~32 ℃) were reviewed. Results  The procedures underwe nt fluently and only 2(0.85%) died early postoperatively. No low cardiac output , arrhythmia and cer ebral embolism complications was found. Conclusion Results sugg ested that mitral valve replacement in beating heart is a safe and available method and is good in extenuating myocardial and pulmonary i njury from ischemia-reperfusion and deep hypothermia.

ABSTRACT

Objective To compare the clinical efficiency of intracardiac procedures on traditional cardioplegic arrested-heart and on-pu mp beating-heart for congenital heart disease (CHD) with severe pulmonary hyper tension. Methods Among all 153 cases, 95 cases underwent operat ions on cardioplegic arrested-heart, while 58 on-pump beating-heart. In arres ted-heart group, 79 cases with ventricular septal defect (VSD), 13 with atria l septal defect (ASD) and 3 with patent ductus arteriosus (PDA) were examined whi le in beating-heart group, 43 cases with VSD, 10 with ASD, and 5 with PDA were examined. Results There were 12 cases of operative death (12.6%) and 8 of tracheotomy (8.4%) in heart arrested group. No operative death and tracheotomy in beating-heart group. 141 patients were followed up for 3 months to 10 year s with good recovery. There were 2 cases of right heart function failure six yea rs later in arrested-heart group. Conclusion Results sugges t that on-pump beating-heart technique is superior to traditional cardiopl egic arrested-heart for CHD with severe pulmonary hypertesion. The cause might be t hat on-pump beating-heart intracardiac operation is more effective in cardio pulmon ary protection.
