Patient Risk-Benefit Preferences for Transcatheter Versus Surgical Mitral Valve Repair.

ABSTRACT:

Background

Transcatheter edge-to-edge repair (TEER) of mitral regurgitation is less invasive than surgery but has greater 5-year mortality and reintervention risks, and leads to smaller improvements in physical functioning. The study objective was to quantify patient preferences for risk-benefit trade-offs associated with TEER and surgery.

Methods and results

A discrete choice experiment survey was administered to patients with mitral regurgitation. Attributes included procedure type; 30-day mortality risk; 5-year mortality risk and physical functioning for 5 years; number of hospitalizations in the next 5 years; and risk of additional surgery in the next 5 years. A mixed-logit regression model was fit to estimate preference weights. Two hundred one individuals completed the survey: 63% were female and mean age was 74 years. On average, respondents preferred TEER over surgery. To undergo a less invasive procedure (ie, TEER), respondents would accept up to a 13.3% (95% CI, 8.7%-18.5%) increase in reintervention risk above a baseline of 10%, 4.6 (95% CI, 3.1-6.2) more hospitalizations above a baseline of 1, a 10.7% (95% CI, 6.5%-14.5%) increase in 5-year mortality risk above a baseline of 20%, or more limited physical functioning representing nearly 1 New York Heart Association class (0.7 [95% CI, 0.4-1.1]) over 5 years.

Conclusions

Patients in general preferred TEER over surgery. When holding constant all other factors, a functional improvement from New York Heart Association class III to class I maintained over 5 years would be needed, on average, for patients to prefer surgery over TEER.
