Background:
Transcatheter tricuspid edge-to-edge repair (T-TEER) is an emerging technology used to treat severe tricuspid regurgitation (TR). The pivotal trials demonstrating the safety and efficacy of T-TEER exclude patients with severely reduced left ventricular function (≤20%).
Case Summary:
We demonstrate the use of T-TEER in a patient with end-stage hypertrophic cardiomyopathy who suffered acute, torrential TR and subsequently developed cardiogenic shock as a complication of high-risk transvenous lead extraction.
Why Beyond The Guidelines:
Currently, there are no guidelines addressing the nonsurgical emergent management of acute TR.
Discussion:
The TriClip system (Abbott) may have certain advantages when used in managing acute primary TR compared with other valve repair and/or replacement approaches.
Take-Home Message:
TriClip can be considered for urgent use to correct severe TR in hemodynamically unstable patients who are not surgical candidates.
