[Surgical results of postinfarction ventricular septal rupture].

Between 1981 and 1991, 17 consecutive patients underwent surgical repair of postinfarction ventricular septal rupture (VSR). 15 patients were operated upon during acute phase after the onset of VSR. Two patients were operated upon six weeks or more after the onset. Overall hospital mortality was 43% in the reviewed group. Our experience suggested that the number of the patients over 70 years of age increased and prevalence in VSR associated with the multivessel coronary artery disease was recognized. Despite improved surgical techniques and enhanced myocardial protection, our experience with surgical treatment of VSR was not as successful as we had hoped. Delay of operation is likely to produce hemodynamic instability and may increase operative mortality. In conclusion, the preoperative mechanical and pharmacological support should be performed, even if the patient is not so critically ill, and the earlier operation might lead to more favourable results in the surgery of the postmyocardial infarction ventricular septal rupture. In addition, preoperative coronary angiography for the precise evaluation of the coronary artery lesions might contribute to better results in the late phase of postoperative period.

[Spontaneous coronary artery dissection: a case report and a review of literature].

Operative cases of spontaneous coronary artery dissection have rarely been reported. We report an operative case of spontaneous right coronary artery dissection. The patient was a 60-year-old man with a history of angina pectoris. A selective coronary angiography demonstrated the dissection of right coronary artery #2-#3 and the stenosis in both 4 postero-lateral branch and left anterior descending artery. He was successfully managed with aorta-coronary bypass. Postoperative coronary angiography revealed the existence of dissecting lesion, however the native RCA flow was improved.

[Clinical application of total body retrograde perfusion to aortic dissection operation].

Open distal anastomosis technique proposed by Cooley facilitates operative management of aortic dissection. Usually this procedure is performed under circulatory arrest, therefore, prolonged management is hazardous to cerebral and visceral organ systems. We have utilized profound hypothermia with total body retrograde perfusion: 1) myocardial protection through coronary sinus, 2) cerebral perfusion through superior vena cava with pretreatment of cerebral protective drugs, 3) abdominal visceral perfusion through inferior vena cava). We have obtained good results with this method in consecutive four patients with aortic dissection.
