Key result
TTVr can precipitate acute afterload mismatch and RV dysfunction.
Why the study?
The impact of transcatheter tricuspid valve repair on right ventricular function is less clearly defined, with no prior reports of acute RV dysfunction after the procedure.
Case Report (n=1)
This is the first reported case of acute afterload mismatch and right ventricular dysfunction occurring after transcatheter tricuspid valve repair.
Clinicians should monitor for acute RV dysfunction after transcatheter tricuspid valve repair; first report leaves open incidence and predictors.
Acute afterload mismatch and left ventricular dysfunction after mitral valve repair are well established. The impact of transcatheter tricuspid valve repair (TTVr) on right ventricular (RV) function is less clearly defined. To our knowledge, there are no reports of acute RV dysfunction after TTVr. Here we report a case of acute afterload mismatch after successful TTVr. (Level of Difficulty: Advanced.)

Hagemeyer et al. (2022) conducted a case report in Acute afterload mismatch (n=1). Transcatheter tricuspid valve repair (TTVr) was evaluated. Transcatheter tricuspid valve repair can be followed by acute afterload mismatch and right ventricular dysfunction, as demonstrated in this case report.
