Trends and results in tricuspid valve surgery

Kratz, J. M.; Crawford, F. A.; Stroud, M. R.; Appleby, D. C.; Hanger, K. H.

Forty-six tricuspid valve operations were performed over 12 years. Operations were conservative (two valvotomies, eight DeVega annuloplasties, seven Carpentier rings) in 17 and valve replacement (17 mechanicals, 12 tissues) in 29. Operative mortality rate was improved with better preoperative functional class, use of cardioplegia, or use of annuloplasty. Heart block occurred less with annuloplasty (6 vs 24 percent). Long-term survival was similar with annuloplasty or porcine valve replacement, but was poorer with mechanical valve replacement. Four of eight DeVega annuloplasties failed during the operative (two) or late (two) period. When the anatomy is suitable, we believe the Carpentier ring annuloplasty to be safe and effective. When valve replacement cannot be avoided, we believe replacement with a tissue valve is preferable.
