Abstract
|
|
|
From Jan 1982 through Dec 1991, thirty-three De Vega's tricuspid annuloplasties were performed in association with mitral and combine mitral and aortic valve disease. Preoperatively, all of the patients were in MYHA functional class III or IV.
There
were one early death and 4 patients died during follow up period of 18 to 138 months(mean follow up: 67.3 months). Nine patients required reoperation because of biological mitral valve failure at 4.7 to 11 years after tricuspid annuloplasty(TAP).
Among these patents, 2 cases needed for reoperation of TAP due to loosening of suture material. Twenty four(86%) of the survivors were in NYJA functional class I or II after TAP. The actuarial survival rate for the TAP was 74% at 138 months. Rt
atrial
pressure of 9 reoperation cases were significantly decreased(P<0.05) compared with initial Rt. Atrial pressure(Mean period; 93.6 months).
Doppler echocardiographic studies for tricuspid regurgitation were performed in 15 cases after TAP (Mean period: 42.3 months). These results showed significantly reduced(P<0.01) tricuspid annulus diameter and tricuspid regurgitation
distance(P<0.05).
Our surgical experience that the DeVega's TAP is a simple, safe, effective procedure and resulted in good hemodynamic improvement with moderate to severe functional tricuspid regurgitation. (Korean J Thoracic Cardiovas Surg 1993;26:827-32)
