Background:
Leadless cardiac pacemaker (LCP) requires large-caliber venous sheaths for device placement. Sheath sizes for these procedures vary from 18- to 23-French (F). The most common complications are hematomas, pseudoaneurysms, and arteriovenous fistulas. Complete and secure closure of the venous access is an important step at the end of such a procedure.
Methods:
We performed a retrospective analysis of all patients who had undergone LCP implantation at our institution. Patients and procedural characteristics as well as groin complications at 30 days and 3 months were evaluated. After sheath removal venous access sites were closed performing a so-called "purse-string" suture (PSS).
Results:
Seventy-seven patients received an LCP at our institution. In 27 (35%) of these patients a heparin bolus was given at the beginning of the procedure. Anticoagulation therapy with phenprocoumon was present in 32 (40%) of patients. In 76 (98.7%) patients, the LCP was implanted without complications. In one (1.3%) patient a perforation occurred during implantation, which required surgical intervention. Access site complications occurred in three (3.9%) patients, two (2.6%) groin hematomas, and one (1.3%) arteriovenous fistula. The hematomas disappeared completely after 3 weeks, and the fistula was not detectable by ultrasound anymore after 4 weeks.
Conclusion:
Use of subcutaneous absorbable double PSS closure after removal of large-caliber venous sheaths is a safe technique to achieve immediate postprocedural hemostasis. Especially for sheath sizes with an inner diameter of 23F, this technique creates a very secure and also cosmetically appealing closure.
