Mid-term and Long-term Outcomes of Posterior Plication Annuloplasty (Modified Davila Annuloplasty) for Functional Tricuspid Regurgitation / 대한흉부외과학회지

ABSTRACT

BACKGROUND: Many types of tricuspid annuloplasty are used in surgical correction of functional tricuspid regurgitation (FTR). We evaluated the mid-term and long-term outcomes in patients treated with a posterior annular plication technique (a modified Davila technique) for FTR. MATERIAL AND METHOD: Between January 1991 and August 2006, 58 adult patients (male, 22; female, 36) with FTR of grade 2/4 or more or with tricuspid annular dilatation of more than 5.0 cm in diameter, even with an FTR of less than grade 2, had received a posterior annular placation. Preoperatively, 26 patients (44.8%) had a grade 3 or more FTR. All patients had received a mitral valve replacement, and 20 (34.5%) had concomitant aortic valve replacement. RESULT: During the mean follow-up period of 101.4+/-51.6 months, FTR disappeared or remained trivial in 28 patients (49.1%), was grade 2~3 (> or =grade 2 and patients (14.0%), and grade 3 in 2 (3.5%). Postoperative FTR was significantly improved compared with preoperative scores (2.66+/-0.73 vs. 0.82+/-0.89; p<0.0001). Patients did not require a second surgery for FTR and did not show further FTR aggravation.

CONCLUSION:

The modified Davila posterior annular plication technique for FTR has reasonable mid-term and long-term results and is a useful surgical procedure.
