Percutaneous versus open surgical cannulation for minimal invasive cardiac surgery; immediate postprocedural outcome analysis.

Abstract

Open surgical cannulation (SC) is traditionally used for cardiopulmonary bypass cannulation in minimally invasive cardiac surgery (MICS). The percutaneous cannulation (PC) technique using arterial closure devices has also been used in select centers. The aim of this study was to compare outcomes between patients undergoing the PC or SC approach, with a particular focus on cannulation-related groin complications. A retrospective analysis of patients undergoing MICS at our institution between January 2018 and April 2022 was performed. Starting from June 2020, 3 surgeons at our institution started using the PC approach. For patients in the PC group, a primary suture-based technique (ProGlide) complemented by a small-sized plug-based closure device (AngioSeal) was used. The primary end point of the study was groin complications following the procedures. A total of 524 patients underwent MICS through a right lateral minithoracotomy during the study time period. Of these, 88 patients (17%) were cannulated using PC approach and 436 (83%) using SC approach. The total number of cannulation-related groin complications was greater in the SC group (4% vs 0%, P=.05). Propensity score matching resulted in 2 comparable groups, with 172 patients in the SC group and 86 patients in the PC group. The number of groin complications remained greater in the SC group (P=.05). In-hospital mortality was comparable between groups (1% PC vs 0% SC, P=.3). The PC approach is a safe cannulation technique for patients undergoing MICS. It minimizes postoperative groin complications with no obvious negative impact on outcomes.
