Technical advances both in cardiac surgery and relating to anesthesia,cardiopulmonary bypass and myocardial protection have significantly improved the prognosis for patients combined with coronary heart disease and heart valve disease. In addition to technology, variable factors that affect operative survival following combined operation include the severity of valvular disease, the number of coronary vessels affected, impairment of left ventricular function and both age and gender differences. In this article, we review the outcome of surgical intervention for heart valve disease combined with coronary heart disease and discuss future prospects in this field.
Abstract:Since 1978 the definition of prosthesis-patient mismatch（PPM） was first introduced by Rahimtoola, it has attracted the attention of foreign researchers. The PPM phenomenon is concerned to be an important factor which will affect patients＇ survival rate and quality of life. Till now, a lot of effort should still be put on this problem. But unfortunately, this problem is still being neglected in our country. This paper is a review of PPM from it＇s many aspects, such as definition, current research status, prevention, and it＇s research prospect. We hope this paper will intensify the clinicians＇ knowledge on PPM.
Objective To summarize the experience of surgical treatment for 84 patients with aortic dissection, investigate the surgical technique and perioperative treatment, and to improve surgical results. Methods The operations were performed in 50 patients with aortic dissection of Stanford A， Bentall or Cabrol operations were performed in 24 patients, graft replacement of ascending aorta in 8 patients, Trusler operation in 5 patients, Wheat operation in 5patients, operation of ascending aorta and aortic arch in 8 patients.Stentgraft were used in 34 patients with aortic dissection of Stanford B. Results There were 11 hospital death,the hospital mortality was 13.1%.There were 3 operative deaths.One patient with ascending aortic and hemiarch grafting died of aortic root bleeding;one patient with replacement of ascending aorta died of failure to restart heart beating；one patient with ascending aortic and hemiarch grafting died of rapture of aortic dissection. There were 8 postoperative deaths, including low cardiac output syndrome in 2 patients, lung infection in 2 patients, renal failure in 2 patients， respiratory failure in 1 patient and permanent mental anomaly in 1 patient. The complications were occurred in 16 patients. The followup period was 3 months to 10 years, and carried out in 62 patients（84.9%，62/73).One died of endocarditis, another one died of sudden death. Conclusion The surgicaltreatment of aortic dissection could be carried out safely based on the accurate diagnosis， specific surgical strategy and fine surgical technique.
