arious new technical approaches have emerged as promising alternatives to conventional aortic valve replacement (AVR) for severe aortic stenosis in the elderly and high-risk patients with multiple comorbidities. Transcatheter aortic valve implantation (TAVI) and rapid deployment or sutureless AVR (SU-AVR) are among the most promising approaches.Several studies on SU-AVR reported that this method could reduce the time of aortic cross-clamp (ACC) and cardiopulmonary bypass (CPB). Moreover, SU-AVR facilitates the use of a minimally invasive approach and concomitant cardiac surgery, and it is associated with excellent hemodynamic and clinical outcomes. 1-6 However, SU-AVR is also associated with a considerably higher rate of permanent pacemaker implantation (PPI) than conventional AVR. Recent studies have proposed several surgical precautions and recommendations, including precise posi-tioning of the guiding sutures or holder angle, evaluation of the extent of annular decalcification required, and reduction in inflation pressure, to avoid conduction disturbance. 7,8 Therefore, our study aimed to assess the early clinical and hemodynamic outcomes in 121 Korean single-institution patients with severe aortic stenosis who underwent Perceval SU-AVR and to introduce a modified guiding suture technique for reducing PPI after SU-AVR.
