Concomitant heart failure (HF) and mitral valve disease (MVD) portend significant morbidity and mortality. Although associated Tricuspid regurgitation (TR) is a common occurrence in this scenario, it is not well known whether there are additional prognostic implications. We sought to assess whether coexistent TR is associated with higher readmission rates or increased mortality in patients with HF and MVD. We identified 1,520,871 encounters with a primary diagnosis of HF in the 2013 to 2014 Nationwide Readmission Database. We excluded patients without MVD, patients <18 years old, those with rheumatic heart disease and infective endocarditis. We also excluded patients who were discharged in December, hospital transfers, and cases where follow-up or outcomes were missing. Logistic regression was used to evaluate the association between baseline characteristics (including the presence of tricuspid valve disease), mortality as well as 30-day readmission rates. A total of 221,127 admissions with HF and MVD were identified. Median age was 79 years (IQR, 67 to 87), 55% were female, 2.7% died during hospitalization, and the 30-day readmission rate was 20.3%. Nearly 1/3 had concomitant TR (n = 78,356, 35%). The presence of TR was neither associated with elevated risk of mortality (hazard ratio 0.98, 95% confidence interval 0.93 to 1.04) nor 30-day readmission rate (odds ratio 1.01, 95% confidence interval 0.98 to 1.03). HF accounted for 33% of 30-day readmissions, while combined cardiac causes accounted for 54%. In conclusion concomitant TR in patients with HF and MVD was not associated with worse short-term outcomes in terms of inpatient hospital mortality and 30-day readmission rates.
