Single-Center Outcomes with Rapid Deployment Aortic Valve Replacement.

Objectives:  Rapid-deployment valves can reduce procedural times and may facilitate minimally invasive surgery. In our institution, more than 500 patients underwent rapid deployment aortic valve replacement (AVR).

Methods:  A total of 510 patients underwent rapid deployment AVR between March 2012 and September 2017, of whom 270 patients underwent isolated AVR and 240 underwent AVR with concomitant procedures. The cumulative follow-up time was 1,444 patient-years, the median follow-up time 2.8 years, respectively RESULTS:  An early all-cause mortality of 3.5% ( = 18) was seen with a cumulative survival of 91.9 ± 2.2% after 12 months. Mean cross-clamp times were 37 ± 19 minutes for isolated AVR and 93 ± 29 minutes for AVR with concomitant procedures. The rate of new pacemaker implantation was 7.8% ( = 40). No case of structural degeneration occurred in the follow-up. Three (0.6%) cases of endocarditis were registered.

Conclusions:  Rapid deployment AVR can be performed safely with low complication rates and good hemodynamic results. Therefore, the relevance in aortic valve surgery can be stressed.
