Authors' conclusion

The vTR2/3 in context of HFrEF was independently associated with the presence of sMR, increased pulsatile loads, and a pronounced RV-PA uncoupling over almost the entire afterload range. Future studies will need to determine under which haemodynamic conditions a mechanical tricuspid regurgitation reduction in HFrEF patients is advisable.

Study context

Population
Heart failure with reduced ejection fraction (HFrEF) patients, with RV pressure-volume loop and Swan-Ganz catheter data integrated with RV/left ventricular (LV) imaging findings
Participants
134 HFrEF patients
Exposure
vTR2/3 compared with vTR0/1

Further findings

RV-PA uncoupling across total afterload range (Ea tertile)

RV-PA uncoupling observed across the entire total afterload range; larger and more dysfunctional RV in vTR2/3 compared with vTR0/1, independent of the afterload

All-cause mortality

RV-PA uncoupling and reduced PA compliance were independently associated with all-cause mortality
