“…Avoiding complete decalcification and oversizing may also reduce the PPI incidence rate. 71 Fabre et al 72 discontinued ballooning at the time of deployment based on the assumption that ballooning could cause compression of conduction by the prosthesis due to postoperative edema, resulting in a significant reduction in the PPI incidence from 16% to 5%. The recent meta-analysis also demonstrated a decline in the PPI incidence rate since 2016.…”

Sutureless or rapid deployment valves in the setting of aortic valve replacement (AVR) is an emerging surgical technique using the transcatheter valve technology, which may lead to reduction in cross-clamp time and potentially better hemodynamics compared to a stented bioprosthetic valve. The absence of subannular pledgets results to excellent hemodynamic performance with reduced turbulent flow and larger effective orifice area. However, complications from both surgical and transcatheter AVR may still occur and impact survival. The incidence of paravalvular leakage and permanent pacemaker implantation are not low. Although technical modifications can improve these outcomes, there is a learning curve effect. Therefore, technical and anatomical considerations as well as better patient selection are paramount for better outcomes. In this review, we discuss the use of sutureless or rapid deployment valves in setting of (1) complex procedures, (2) minimally invasive AVR, and (3) small aortic annulus. The advantage of sutureless or rapid deployment valves in terms of mortality remains to be clarified; therefore, it is necessary to accumulate long-term outcomes in an appropriate patient cohort.

“…1), this will result in single-digit gradients even in the small-size valve. [8][9][10] If the Perceval valve is correctly sized (Fig. 1), one should see a symmetric and linear coaptation line of the 3 leaflets in the shape of a "Mercedes star sign."…”

“…Even when using the small Perceval valve, the resulting transvalvular gradients are as low as single digits, and the hemodynamics are excellent. 1,[6][7][8][9][10]14 This is because the low profile of the valve frame is such that when the leaflets open, they are essentially opening to the dimensions of the aortic root.…”
