A prospective, randomized multi-center trial explored the clinical outcomes in 100 patients undergoing either conventional AVR or minimally invasive rapid deployment AVR (RDAVR). RDAVR consists of positioning the valve with a precrimped subannular skirt frame into the annulus, and then balloon deploying the frame. Implanted valve sizes were similar. RDAVR was associated with shorter X-clamp times. Early outcomes were similar. RDAVR patients had less patient-prosthesis mismatch at 3 months post-op.
