Analysis of surgical treatment of severe valvular heart disease

Abstract

Objective To investigate the effects of surgical treatment of severe valvular heart disease to improve early survival. Methods 100 cases with severe heart valve surgery were opercted,The mitralvalve replacement (MVR) in 50 cases, aortic valve replacement (AVR) in 30 cases, MVR + AVR in 20 cases;tricuspid valvuloplasty (TVP) in 50 cases,dissection of left atrial thrombus in 25 cases,left atrial plication in 12 cases,coronary artery bypass grafting(CABG) in 20 patients; The Ⅲ grade of heart function( n = 60), Ⅳ grade( n = 40). Results A total of 4 cases died(4％ )died of postoperative low cardiac output syndrome in 1 case, sudden ventricular fibrillation in 3 cases died,the other 96 cases discharged;heart function recovered to 10 cases of grade Ⅰ, Ⅱ Grade 29 cases, Ⅲ grade 14 cases. Postoperative cardiothoracic ratio reduced to varying degrees;The 12 cases(40％ ) with aortic valve calcification or hardening,13 cases(26％ ) with mitral valve sclerosis or calcification in patients with severe valvular heart disease by echocardiography; The left ventricular end-diastolic diameter(LVEDD) (53 ± 7.0) mm after 20 months were lower than the discharge ( 64.0 ± 6.2) mm( t = 3.789, P ＜ 0.05 ) ; The left ventricular ejection fraction (LVEF)after 20 months(42.5 ±11.0)％were highter than that at discharge(37.5 +6.2)％ ,(t =3.799,P ＜0.05). Conclusion Improving heart function, keeping the flap tissue to enhance prevention of postoperative complications, could significandy improve the results of valve replacement for the patients with severe valvular heart disease.
