ABSTRACT
Transcatheter edge-to-edge repair (TEER) has emerged to address severe mitral and tricuspid valve regurgitation in patients who are at high perioperative risk for open-heart surgery. No clinical data is available for continuous left and right atrial pressure monitoring using the steerable guiding catheter (SGC) during TEER. In a prospective single-center study, 40 patients with severe mitral (n = 20) or tricuspid (n = 20) regurgitation underwent TEER with the registration of atrial pressure via the SGC. All patients had successful TEER using the PASCAL Ace repair system, while atrial pressure was monitored continuously via the SGC. Simultaneous right or left atrial pressure monitoring via the SGC and a pigtail catheter during mitral and tricuspid TEER showed excellent reliability for SGC pressure registration. While for mitral TEER the beneficial effects of continuous atrial pressure monitoring are well known, we further evaluated the outcome of patients with tricuspid TEER. Echocardiographic and clinical results after tricuspid TEER showed a reduction of quantitative echocardiographic tricuspid regurgitation parameters and improved New York Heart Association classification after 3-month follow-up. Also, qualitative tricuspid valve assessment showed improved tricuspid regurgitation classification postimplantation and at 3-month follow-up. Furthermore, right atrial pressure was reduced by 37.6% and mean right atrial pressure by 30.6% after successful tricuspid TEER using the PASCAL Ace device. Continuous atrial pressure monitoring using the SGC of the PASCAL Ace repair system is reliable during mitral and tricuspid TEER. Furthermore, successful tricuspid TEER leads to reduced right atrial pressure.
