National 10-year trends and outcomes of isolated and concomitant tricuspid valve surgery

Structured PICO

What are the trends and comparative in-hospital outcomes of isolated versus concomitant tricuspid valve surgery?

Population

6,868 patients who underwent tricuspid valve repair/replacement (TVR) between 2005-2014 identified from the National Inpatient Sample.

Intervention

Isolated tricuspid valve repair or replacement (n=1,601)

Comparator

Concomitant tricuspid valve repair or replacement

Outcome

In-hospital mortality, permanent pacemaker requirement, blood transfusion rates, and post-procedure length of stayhard clinical

Tricuspid valve surgery volume has increased over a 10-year period but remains associated with high in-hospital mortality and morbidity, with valve replacement carrying significantly higher mortality than repair.

Abstract

BACKGROUND: The data on the trends and comparative outcomes after isolated and concomitant tricuspid valve repair/replacement (TVR) is scarce. METHODS: The International Classification of Diseases - 9th version was used to identify the patients who underwent TVR, using the National Inpatient Sample. Outcomes were evaluated using the analysis of variance and Chi-square test, and trends across the years were tested via Cochran-Armitage Test. RESULTS: Of 6868 patients who underwent TVR between 2005-14, 1601 (23%) were isolated. Over the 10-years period, the number of total and isolated TVR has steadily increased (P50 years, heart failure, cerebrovascular accident, end-stage renal disease, peripheral vascular disease, liver disease, and TV replacement. CONCLUSIONS: Both isolated and concomitant TVR has increased over the last 10 years, however is associated with high mortality, complications, need for skilled facility placement, and longer LOS. The mortality after TV replacement was significantly higher than that after repair.
