BACKGROUND

Transcatheter treatment techniques for tricuspid regurgitation (TR) have evolved in recent years, with leaflet repair being the most commonly used, but thus far evidence on the PASCAL and PASCAL Ace system is based mainly on compassionate use data.

OBJECTIVES

This is the first report on commercial use in a multicenter study with a large patient cohort investigating the safety and efficacy of the PASCAL and PASCAL Ace system in the treatment of TR.

METHODS

In a retrospective, multicenter, observational setting, data from all consecutive patients undergoing leaflet repair for TR at 8 centers was collected, including a centralized analysis of echocardiographic data.

RESULTS

A total of 235 high-risk patients (mean age 78 ± 8 years, 49% women, mean Society of Thoracic Surgeons Predicted Risk of Mortality score 8.6% ± 6.8%) were included. TR was functional in 87% of patients and graded severe or higher in 91%. TR was successfully reduced to moderate or less in 78% of patients (P < 0.001). Procedural success was 78% (n = 153). At the latest available follow-up (median 173 days), TR reduction was sustained (78% with TR moderate or less; P < 0.001), and echocardiography showed indications of right ventricular remodeling (mean right ventricular end-diastolic diameter 56 ± 9 mm vs 53 ± 9 mm; P < 0.001). Patients' symptoms diminished significantly (63% were in New York Heart Association functional class I or II at follow-up; P < 0.001). In a device-specific analysis, the PASCAL and PASCAL Ace showed no difference in TR reduction (postprocedural TR moderate or less in 77% vs 78%; P = 0.82).

CONCLUSIONS

In early clinical experience, the PASCAL (Ace) leaflet repair system has high technical and procedural success rates with efficient TR reduction and significant clinical and echocardiographic improvement at follow-up.
