Abstract:
Objective The early causes of death were analyze in 2349 patients who had undergone heart valve replacement.Methods Methods From January 1995 to December 2007,2349 patients with heart valve diseases received heart valve replacement.1109 cases were male and 1240 were female.The mean age of the patients was(41±19)years old.1962 cases had rheumatic heart valve disease,308 had congenital heart valve disease,39 had infective endocarditis,29 underwent reintervention by heart valve replacement,11 had Marfan syndrome.34 cases with coronary heart disease underwent heart valve prosthesis implantation and coronary artery bypass grafting.Mitral valve replacement(MVR)was performed in 1333 patients,aortic valve replacement(AVR)in 271,double valves replacement(DVR)in 736 and tricuspid valve replacement(TVR)in 9.There were 3075 mechanical valves and 10 bioprosthetic valves.Results From 1995 to 1999,death occurred in 16 of the 235 cases,early mortality rate was 6.81%.From 2000 to 2004,death occurred in 35 of the 1087 cases,early mortality rate was 3.22%.From 2005 to 2007,there were 29 deaths among 1027 cases,with an early mortality rate of 2.82%.Overall early mortality rate was 3.40%.The early mortality rate was 2.32%(31 in 1333 cases)in patients who underwent MVR,3.32% (9 in 271)in patients who underwent AVR,5.24%(40 in 736)in patients who underwent DVR,5.50%(7 in 127)with LVEDD≥70 mm,4.60%(14 in 304)with LVEF<0.40,2.14%(9 in 419)with NYHA class II,2.42%(37 in 1529)with NYHA class Ⅲ,and 8.48%(34 in 401)with NYHA class IV.The causes of 80 deaths were low cardiac output syndrome in 31 cases(38.8%),renal failure in 14 cases(17.5%),arrhythmia in 10 cases(12.5%),pulmonary infections in 8 cases (10.0%).cerebrovascular accidentin 5(6.3%),left ventricular rupture in 5(6.3%),multisystem and organ failure in 5(6.3%),and other cause in 2 cases(2.5%).Conclusion The causes of early death after heart valve replacement are low cardiac output syndrome,renal failure,arrhythmia,pulmonary infection,cerebrovascular accident,left ventricular rupture and multisystem and organ failure.
