Abstract:
Objective:To explore the value of transesophageal echocardiography(TEE) guidance for transcatheter DragonFly? system edge-to-edge tricuspid regurgitation (TR) repair.Methods:Five cases who were chosen in the Second Affiliated Hospital, Zhejiang University School of Medicine from December 2020 to January 2021 with surgical high-risk and severe functional TR underwent transcatheter DragonFly edge-to-edge repair with the guidance of TEE. Preoperative TEE was used to evaluate the tricuspid valve anatomy and the origin and etiology of regurgitation in detail; intra-procedure guidance of TEE was performed during the DragonFly system for tricuspid valve edge-to-edge repair intervention and after release of the DragonFly clip, the effect of surgery was assessed immediately and compared with pre-procedure TEE.Results:A total of 10 DragonFly clips were implanted in 5 patients (3 in each of patients, 2 in 1 patient, and 1 in each of patients). One of the 3 clips in 1 patient fell off unilaterally from the septal valve after release, and the other 9 clips were well positioned and fixed. Immediately post-operation assessment by TEE depicted the TR in 3 patients declined to mild and 2 to moderate. The vena contracta area by using three-dimensional color blood flow quantitative assessment was reduced[(0.93±0.26)cm 2 vs (0.20±0.11)cm 2]. No complications such as serious tricuspid valve injury, pericardial tamponade, thromboembolism occurred in the 5 patients. Conclusions:TEE plays an important role in guiding and monitoring transcatheter DragonFly system edge-to-edge TR repair during the entire procedure.
