Abstract

Objectives The aim of the present study was to evaluate the prognostic impact and late evolution of associated tricuspid regurgitation (TR) 2/4+ after aortic valve replacement (AVR). Methods We evaluated 61 patients who underwent AVR between 2003 and 2012 (35 for aortic stenosis [AS], 26 for aortic regurgitation [AR]) with associated untreated TR 2/4+. Patients with concomitant mitral disease were excluded. Median follow-up was 3.2 years. Serial echocardiographic and clinical data were collected and analyzed. Results Mean age was 65 ± 13 years; 26% of the patients were in NYHA class III-IV. Left ventricular ejection fraction was 53 ± 11%. Comorbidity included: chronic obstructive pulmonary disease in 5%, chronic renal failure in 13%, coronary artery disease in 20%, history of stroke/TIA in 8%. Thirty-day mortality was 1.6%. Overall actuarial survival was 83 ± 6% at 6.5 years, with a freedom from cardiac death of 90 ± 5%. Freedom from TR ≥3+ was 86 ± 6% at 6.5 years. At last follow-up, 82% of the patients had TR 0-1/4+, 9% had TR 2/4+, 4.5% had TR 3/4+ and 4.5% had TR 4/4+. Occurrence of TR ≥ 3+ at follow-up was associated with increased cardiac mortality (HR 10.5; p = 0.009). Conclusions preoperative untreated TR 2/4+ improves or remains stable in the majority of patients. The poor outcomes associated with TR > 2+ suggest the need for better methods to identify subjects at risk for TR progression. doi: 10.1111/jocs.12656 (J Card Surg 2016;31:9-14)
