Clinical analysis of 1435 eases of cardiac valve replacement

Abstract

Objective To summarize the clinic experience of patients with heart valve disease underwent cardiac valve replacement.Methods The clinic data of 1435 patients underwent cardiac valve replacement from March 2005 to September 2012 were retrospectively analyzed.Among them,there were 1219 cases of rheumatic heart disease,216 cases of other etiological factor.According to New York Heart Association,58 cases were in heart function first class,322 cases were in second class,993 cases were in third class,62 cases were in fourth class.Respectively,there were 867 cases of mitral valve replacement,253 cases of aortic valve replacement,315 cases of mitral valve combining aortic valve replacement,2 cases of tricuspid valve replacement.Simultaneously,there were 329 caes of tricuspid valve shaping,28 cases of coronary artery bypass grafting,63 cases of left atrial thrombectomy,14 cases complicating other operation.Results There were 24 cases (1.67％) of earlier death,the cause of death was mainly low heart output syndrome and cardiac dysrhythmia,accounting for 50％.Earlier operation complications including 142 cases of various cardiac dysrhythmia,53 cases of lung complication,43 cases of low heart output syndrome and water-electrolyte disturbances.Later complication mainly including chronic congestive heart failure and cardiac dysrhythmia.Conclusions Cardiac valve replacement is a good method to cure valvular disease of the heart.Sufficiently preoperative preparation,suitable operation opportunity,perfectly surgical technic and surgical idea,timely and precisely perioperative disposal all are capital measurement to reduce complication and improve curative effect.After operation,positively prevent and cure chronic heart failure,moderate anticoagulation are important factors to guarantee patients long-term survival.
