Interventional percutaneous repair of tricuspid and mitral regurgitation is an alternative to surgery in fragile patients. Since reliable methods documenting the procedural benefit are lacking, we assessed innovative monitoring strategies using activity tracking devices (ATDs).
We analyzed 15 patients with percutaneous repair of severe tricuspid and/or mitral regurgitation (grade 3 or 4). Procedural benefit was prospectively monitored by the Minnesota Living With Heart Failure Questionnaire (MLHFQ), 6-minute walk test (6MWT) and utilization of ATDs (Fitbit, San Francisco, USA). ATDs recorded steps over a mean of 6.3 (baseline) and 7.3 days (follow-up after a mean of 68 days).
Procedural results were categorized in moderate (< 2 grades) and good (≥ 2 grades) improvement of echocardiographic regurgitation (see figure). 6MWT failed to detect physical improvement in the moderate group (Δ1,1%) and MLHFQ increased slightly. ATD demonstrated reliable identification of enhanced physical activity after echocardiographic improvement. ATD showed higher correlation to pro-BNP (Pearsons correlation coefficient 0.61) than the correlation of MLHFQ to pro-BNP (0.43) or 6MWT to pro-BNP (0.52).
ATD monitoring of one-week physical activity appears to be more representative and less influenced by co-factors for the measurement of clinical improvement after percutaneous tricuspid/mitral valve repair compared to MLHFQ or snapshot evaluation by 6MWT.
