Sutureless Valve Implantation via Mini J-Sternotomy: A Single Center Experience with 2 Years Mean Follow-up
Key result
Minimally invasive sutureless AVR is linked to ~2% 30-day mortality in aortic stenosis.
- n=145
Why the study?
Minimally invasive cardiac surgery reduces morbidity but increases operative time; sutureless aortic bioprostheses may simplify implantation by reducing ischemic time.
Population
145 patients with aortic valve stenosis undergoing surgical AVR via mini J-sternotomy
Comparison
Sutureless bioprosthesis implantation via mini J-sternotomy (no comparator)
Design
Single-center observational cohort study
Follow-up
23.5 ± 14.4 months

Population
145 patients (mean age 77.8 years, 55.2% female) with aortic valve stenosis undergoing sutureless aortic valve replacement via mini J-sternotomy, followed for a mean of 23.5 months.
E
Exposure
Sutureless bioprosthesis (Perceval) implantation via mini J-sternotomy.
O
Outcome
Clinical and echocardiographic outcomes (including mortality, pacemaker implantation, and transprosthetic gradients).
Sutureless aortic valve replacement via mini J-sternotomy demonstrates satisfactory clinical and hemodynamic outcomes at 2 years follow-up.
Cite This Study
Fischlein et al. (2015) conducted an observational in Aortic valve stenosis (n=145). Sutureless aortic valve replacement via mini J-sternotomy was evaluated on 30-day mortality. Sutureless aortic valve replacement via mini J-sternotomy in patients with aortic stenosis resulted in a 30-day mortality of 2.1% and a 7.6% rate of pacemaker implantation.
