This is a difficult question and the answer is uncertain. The authors review the state of the art of the three methods in 1993. Cardiac transplantation seems to have attained its maturity. The annual number of transplant operations is stagnant and the results progress little. Functional rehabilitation is excellent, the essential immunosuppression which has not changed in principle over the last 12 years, remains prejudicial. Cardiomyoplasty is an attractive concept with difficult surgical indications (Stage III, moderately dilated cardiomyopathy with good right ventricular function without arrhythmias, pulmonary hypertension or mitral regurgitation), a delayed efficacy, a hospital mortality comparable with that of transplantation and a similar survival rate. The objective results are not as good as the more subjective functional improvement. This limited experience (about 500 patients in 50 centers throughout the world, 70% of whom are European) should be continued and evaluated in the centers which initiated it. The artificial heart is only a temporary though essential therapeutic option in certain extremely urgent situations. It is a form of circulatory assistance, ranging from the simple univentricular accessory pump to the univentricular (Novacor) or biventricular (Jarvik) heart, in a rapidly evolving technology with problems of energy sources, marketing, cost and also clinical management which is often difficult especially with respect to coagulation. What do the next ten years hold in store for us? A nex immunosuppressor or the xenograft? A more efficient cardiomyoplasty with more precise medications? A totally implantable autonomous artificial heart? Can economic considerations accompany this development? This is undoubtedly the deepest source of concern for the future.
这是一个难题,答案并不确定。作者回顾了1993年这三种方法的发展现状。心脏移植似乎已趋于成熟。每年的移植手术数量停滞不前,结果进展甚微。功能康复效果良好,过去12年基本未变的主要免疫抑制疗法仍然存在弊端。心肌成形术是一个有吸引力的概念,但手术指征严格(Ⅲ期,中度扩张型心肌病,右心室功能良好,无心律失常、肺动脉高压或二尖瓣反流),疗效延迟,医院死亡率与移植相当,生存率也相近。客观结果不如更主观的功能改善情况。这种有限的经验(全球50个中心约500例患者,其中70%为欧洲患者)应在发起该研究的中心继续进行并评估。人工心脏只是在某些极其紧急的情况下一种虽必不可少但只是临时的治疗选择。它是一种循环辅助形式,从简单的单心室辅助泵到单心室(诺瓦科尔)或双心室(贾维克)心脏,技术发展迅速,存在能源、市场推广、成本以及临床管理等问题,尤其是在凝血方面临床管理往往很困难。未来十年我们会面临什么?一种新的免疫抑制剂还是异种移植?一种使用更精确药物、效率更高的心肌成形术?一种完全可植入的自主人工心脏?经济因素能否伴随这一发展?这无疑是对未来最深切的担忧之源。
