Minimal access rapid deployment aortic valve replacement: initial single-center experience and 12-month outcomes

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Heart Valve Disease

Background:

• Minimally invasive aortic valve replacement (AVR) offers potential benefits over traditional sternotomy.
• Rapid deployment valves aim to reduce surgical time and improve patient outcomes.
• The Edwards Intuity valve system is designed for efficient implantation in minimally invasive AVR.

Purpose of the Study:

• To evaluate the feasibility of rapid deployment AVR using the Edwards Intuity valve system.
• To assess short-term clinical and hemodynamic outcomes of this minimally invasive approach.
• To present the 12-month follow-up results for this specific valve system.

Main Methods:

• A single-center observational study involving 60 patients undergoing AVR.
• Utilized a partial sternotomy approach for minimally invasive implantation of the Edwards Intuity valve.
• Clinical and echocardiographic follow-up was conducted at 12 months post-implantation.

Main Results:

• Achieved reproducible short crossclamp (26±7 min) and bypass (56±16 min) times.
• Demonstrated favorable short-term hemodynamics with a mean transprosthetic gradient of 11.7±4.3 mm Hg and effective orifice area of 1.8±0.3 cm(2).
• Reported a 30-day mortality of 1.7% and a 12-month late mortality of 5.1%.

Conclusions:

• The Edwards Intuity valve system is feasible for rapid deployment in minimally invasive AVR.
• The valve exhibits good hemodynamic performance comparable to other rapid deployment options.
• Further long-term follow-up is necessary to confirm durability and safety.
