Summary
Rapid deployment aortic valve replacement (RDAVR) using the Intuity Elite and Perceval S valves showed comparable safety outcomes. Both valves demonstrated good hemodynamic performance, with the Intuity Elite offering a larger effective orifice area.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Interventional Cardiology
Background:
- Rapid deployment aortic valve replacement (RDAVR) offers an alternative to traditional methods.
- This study compares two specific RDVs: Perceval S and Intuity Elite.
Purpose of the Study:
- To retrospectively analyze clinical outcomes and hemodynamic performance of Perceval S and Intuity Elite RDVs.
- To compare these valves in a propensity score-matched patient cohort.
Main Methods:
- Retrospective analysis of 372 patients undergoing RDAVR (2012-2018).
- 1:1 propensity score matching created 107 patient pairs for comparison.
- Evaluated perioperative data, hemodynamics, pacemaker implantation, and 30-day mortality.
Main Results:
- No significant differences in cardiopulmonary bypass or cross-clamp times.
- Comparable 30-day mortality and permanent pacemaker implantation rates.
- Intuity Elite showed a higher indexed effective orifice area and lower pressure gradients.
Conclusions:
- Both Perceval S and Intuity Elite RDVs exhibit favorable hemodynamic characteristics.
- Comparable safety profiles regarding 30-day mortality and complication rates were observed.
- RDAVR is a viable option with good outcomes for aortic valve stenosis.
