Utility of the long DrySeal sheath in facilitating transcatheter pulmonary valve implantation with the Edwards Sapien 3 valve.

OBJECTIVE: To assess the utility of the 65-cm-long Gore DrySeal sheath when compared to the standard 36-cm-long Edwards expandable sheath (e-sheath) for transcatheter pulmonary valve implantation (TPVI) with the Edwards Sapien 3 valve. METHODS: All patients who underwent TPVI with the Sapien 3 valve, excluding those performed via hybrid approach, at our center between September 2015 and November 2019 were retrospectively reviewed and compared between two groups. RESULTS: A total of 94 patients were enrolled; 29 patients underwent TPVI with the Sapien valve using the DrySeal sheath and 65 underwent TPVI using the e-sheath. The height and body weight of patients implanted using the DrySeal sheath ranged from 137 to 193 cm and from 33 to 129 kg, respectively. Valve delivery time was significantly shorter in the DrySeal group (median time 4 min 33 s vs. 9 min 6 s, p = .002). There were no complications in the DrySeal group (0/27). Nine procedural complications occurred in the e-sheath group (9/65), five of which were potentially directly related to sheath choice, including tricuspid valve injury in four and embolization of the tip of the e-sheath during retrieval of a ruptured balloon in one patient. CONCLUSIONS: TPVI with the Sapien 3 valve using the 65-cm-long DrySeal sheath facilitates faster and safer valve implantation when compared to the e-sheath.
