RESUMEN
BACKGROUND: Right-sided heart failure (HF) due to severe tricuspid regurgitation (TR) is associated with reduced quality of life (QoL). Here, we analyzed the impact of TR on specific QoL dimensions and the effect of transcatheter tricuspid valve intervention (TTVI) on individual QoL items. METHODS AND RESULTS: In this study, we included 174 patients with HF (49% women; median age, 79 years; 97% New York Heart Association ≥3) with baseline QoL assessment undergoing TTVI by transcatheter edge-to-edge-repair at our center between April 2016 and March 2022. QoL was assessed by the standardized Minnesota Living With HF Questionnaire. QoL change after TTVI and correlation to functional end points were analyzed. In addition, all QoL domains and the 21 individual items of the Minnesota Living With HF Questionnaire were analyzed. TTVI significantly reduced TR (TR ≥3: baseline 95%, 1-year-follow-up 7%; P<0.001). Total Minnesota Living with HF Questionnaire score improved from 37 (interquartile range, 26-50) points to 31 (interquartile range, 17-42) points (median follow-up-interval, 355 days; P<0.001). QoL improvement was associated with positive New York Heart Association class, 6-minute walking distance, and actigraphy changes (all P<0.05). The detailed analysis revealed that all items of the physical-related QoL dimension were impaired at baseline and strongly improved after TTVI. In contrast, the emotional and "social" Minnesota Living With HF Questionnaire dimensions were largely unaffected at baseline, yet specific items improved with TTVI. CONCLUSIONS: In this single-center study, we delineate the QoL-associated disease burden of TR and identify specific QoL items that improved after TTVI. Our findings support TTVI in patients with reduced QoL and may add to the development of specific tools assessing the functional status of an increasing patient population undergoing TTVI.

AIMS: Tricuspid regurgitation (TR) is associated with high mortality, morbidity and reduced physical capacity. This study was designed to examine the long-term impact of transcatheter tricuspid valve intervention (TTVI) on physical activity by using the method of actigraphy. METHODS AND RESULTS: Overall, we prospectively included 128 heart failure patients with severe TR (median age 79 years, 48% female) who were scheduled for TTVI. Patients were equipped with activity tracking devices for 1 week before TTVI, and again at 1-6 months and 1 year after TTVI. We compared continuous physical activity (CPA), defined as the mean number of steps/day with New York Heart Association class, quality of life assessments, and 6-min walk distance (all p <0.01). TTVI reduced TR to grade ≤2+ in 94% of patients. Median (interquartile range [IQR]) CPA at baseline was 3108 (1350-4959) steps/day, which increased by 31.4% to 3958 (1823-5657) steps/day at 1-6 months and 4080 (2293-6514) steps/day at 1 year after TTVI (p <0.001 for both comparisons). The impact of TTVI was significantly higher in advanced heart failure patients with low baseline activity (baseline CPA <1350 steps/day; 1-year CPA increase: +121.3%; p <0.001), when compared to moderate activity patients (baseline CPA 1350-4959 steps/day; 1-year CPA increase: +27.5%; p <0.01) or high activity patients (baseline CPA >4959 steps/day; 1-year CPA change: +2.6%; p = 0.39). CONCLUSION: One-week actigraphy demonstrates durable improvement of physical activity after TTVI. Fragile chronic heart failure patients with very low baseline activity, as determined by actigraphy in this study, significantly benefit from transcatheter intervention and should not be excluded from TTVI.
