FOLLOW UP : 

Instilling insight into the problems of chemoprophylaxis In preventing recurrent attacks of rheumatic fever ( penicillin inj once in every 3 weeks remains necessary until the age of 40 years ) Advice regarding prevention of bacterial endocarditis , particularly in relation to dental problems . Education and counseling regarding anticoagulation. FOLLOW UP

Slide 30: 

30 days Hospital mortality 9.2% cardiac output refractory arrhythmias endocarditis anticoagulant related bleeding air embolism sepsis respiratory insufficiency

Slide 31: 

Late deaths 10.1% CCF Arrhythmias Acute MI Valve thrombosis Anticoagulation related hemorrhage Prosthetic valve thrombosis Paravalvular leak Renal failure pneumonia

Slide 32: 

30 day hospital death rate was 9.2% Late death occurred in 10.1% Actuarial survival- at 5, 10 ,20 and 24 years was 90.4%, 85.6%,84.4%,82.45 per year respectively All the cause of valvular dis was rheumatic 4.6% - calcific MS, 82.7% - severe MR 24.7% - calcific AS, 84.6% - severe AR Stanley john,CMC Vellore, ATS 2000,69:1167-1172

Slide 33: 

15 year follow up after DVR Late survival 5 ,10 and 15 yrs, 92%,78%, 45% Mean survival 154 months Panda,CMC Vellore,J of Heart Valve Dis,March 2009

Slide 34: 

Rheumatic multivalvular disease unless aggressive and timely intervention in the form of replacement /repair is pursued the condition progresses rapidly to disability and death . Combined mitral and aortic replacement represents a major technical challenge and carries high early and late mortality rates .
