Triple valve surgery: long-term follow-up from a single centre

Abstract

Aims: The aims of this study were to analyze early and late outcomes of TVS and identify predictors of short and long- term poor prognosis.

Methods: Single centre retrospective study with 130 patients who underwent TVS between 2007 and 2020. Most of the patients were female (72.3%), mean age of 64.4 years; 61.1% were in New York Heart Association class III/IV, with a EuroSCORE II of 7.5%. Univariable and Multivariable analyses were undertaken to identify predictors of perioperative mortality and morbidity and long-term mortality.

Results: In-hospital mortality was 10.8%, of which 7.6% were due to a cardiac cause. Diabetes Mellitus was an in- dependent predictor of increased perioperative mortality. This group had 27.7% rate of major perioperative complications. Elevated systolic pulmonary pressure and obesity were predictors of early morbidity. All-cause mortality was 43.1% for 14 years. The survival at 1, 5 and 10 years was 83%, 60% and 43%, respectively. Diabetes Mellitus was a risk factor for long-term mortality.

Conclusions: Patients undergoing TVS have a high surgical risk making TVS an operation associated with high mor- tality and morbidity. This research suggests Diabetes Mellitus, pulmonary hypertension and obesity as risk factors for mortality in TVS.
