Natural history of severe tricuspid regurgitation: Outcomes after transcatheter tricuspid valve intervention compared to medical therapy

We aimed to identify the clinical characteristics and examine outcomes in patients with significant tricuspid regurgitation (TR) who received transcatheter tricuspid valve intervention (TTVI) compared with guideline directed medical therapy (GDMT). Between 2015 and 2019, 124 patients with symptomati...

description We aimed to identify the clinical characteristics and examine outcomes in patients with significant tricuspid regurgitation (TR) who received transcatheter tricuspid valve intervention (TTVI) compared with guideline directed medical therapy (GDMT). Between 2015 and 2019, 124 patients with symptomatic severe TR were assessed at St. Michael's Hospital. Seventy-one patients were ineligible and received GDMT only while 53 patients received TTVI and GDMT. During follow-up, TTVI was associated with significant improvements in NYHA functional class and 6-min walk distance (p
