Abstract 3168: Clinical Outcome Beyond 10 Years in Patients Undergoing the Subcoronary Ross Operation: A Single Centre Experience
Background: Long-term clinical outcome in patients undergoing the Ross operation is still a matter of debate especially in the full root technique. We analysed our long term follow-up data (>10 years) in the subcoronary technique only.
Methods: 105 patients ( mean age 49.8±14 years, range 15.1–70.5 years, 79 male) with at least a mean follow-up of 10 years ( mean: 11.5±1.2 years) were evaluated. Underlying valve disease was aortic regurgitation in 32, stenosis in 19 and combined lesions in 54 patients.
Results: Completeness of FU was 98%. Eight cardiac and 4 non-cardiac deaths were observed. Reoperations were necessary in 9 patients: 5 autograft-explantations and 4 homograft-explantations. At last follow-up, 73% were in NYHA class I and 11% in class II. Last exam aortic regurgitation ( AR) was none or trivial in 58 pts, 1/4 in 17 pts, 2/4 in 6 pts, 3/4 in 3 pts, 4/4 in 0 pts and unknown in 7 pts. Homograft-gradients were: <5 mmHg in 19 pts, 5–10 mmHg in 40 pts, 11–15 mmHg in 12 pts, 16 –20 mmHg in 4 pts, 21–25mmHg in 2 pts, >25 mmHg in 0 pts and unknown in 14 pts. Events were: 1 embolism <30d and 9 >30d, 6 bleedings <30d and 7>30d, no endocarditis <30d and 10 >30d. Mortality probability rate was similar to the general German population.
Conclusions: In this series of patients undergoing the subcoronary Ross procedure, long-term follow-up data revealed sustained clinical benefit with a low valve related reoperation rate, excellent hemodynamics and general population similar survival.
