In our long survival cases of total artificial heart (TAH) experiment, three cases survived more than 7 months lately, and the longest survivor lived 288 days. The artificial heart system was total both heart bypass, and the ascending aorta and pulmonary artery were ligated and occluded completely. The natural heart was kept beating to perfuse coronary arteries. Pulmonary and systemic circulation was maintained by the artificial heart.
In post operative cource, the goats have lived well, and the value of hematocrit and total protein has been maintained normal, and anemia and ascites which usually accompanied in the long survivals did not occure. The beating of the remained natural heart was continued until death or the timeof forcedly fibrillating. No specific change was observed on ECG follow up.
This method of TAH cannot only be a resolution to a problem of bypass type TAH, but also with some modifications be applicable to temporally assisted circulation for failing heart.
