Rapid Deployment of Aortic Bioprosthesis in Elderly Patients With Small Aortic Annulus

Abstract

Regarding the low rate of severe PPM and the early regression of left ventricular mass, these preliminary studies indicate the potential benefit of the Intuity bioprosthesis in patients with a small aortic annulus. Midterm results should be evaluated.

Direct Comparison of the Edwards Intuity Elite and Sorin Perceval S Rapid Deployment Aortic Valves

“…Interestingly, this potential benefit of the Perceval over the Intuity RDV did not result in a significantly improved valve performance at discharge echocardiography. Mean pressure gradients of both RDV were comparable in our series and closely reflect data from previous reports showing mean pressure gradients ranging from 10 to 14 mm Hg for the Intuity [8,15,17] and 10 to 16 mm Hg for the Perceval RDV [4,10,19]. Subgroup analysis with respect to implanted RDV sizes revealed that peak pressure gradients were superior for the Intuity size 23 mm compared with the Perceval M. Indexed EOA was greater for all Intuity sizes except in small aortic annuli (21 mm), where the iEOA was significantly higher with the Perceval S size (iEOA Intuity 0.74 AE 0.08 versus Perceval 0.86 AE 0.12 cm 2 /m 2 ).…”

“…The indexed effective orifice area (iEOA; cm 2 /m 2 ) was determined using the effective orifice area (EOA) [4,5] divided by the patient body surface area. Severe patient-prosthesis mismatch was defined as an iEOA of less than 0.65 cm 2 /m 2 [15]. Rapid deployment valve-related complications were defined as those directly attributed to the implantation of the RDV.…”

Comparison of hemodynamic and clinical outcomes of transcatheter and sutureless aortic bioprostheses: how to make the right choice in intermediate risk patients

“…The authors confirmed higher gradients in the SUAVR group, but similar postoperative indexed effective orifice area in both SUAVR and TAVI groups (14). It has been shown that the incidence of severe PPM after Perceval implantation approximately ranges from 0 to 11% (15), after Intuity from 6% to 15% (16,17), and 8% after TAVI (up to 27% if a moderate degree of PPM is considered) (18). There are no data about the impact of PPM after SUAVR on survival, but it has been shown that PPM after TAVI does not have an impact on late-term survival (18).…”

Permanent Pacemaker Implantation After Rapid Deployment Aortic Valve Replacement

“…Although higher than expected, our series compares favorably with a contemporary multicenter study by Mazine and colleagues [9] of the Perceval rapid deployment valve, in which the incidence of PPI after AVR ranged from 12% to 21%. Published European studies report PPI rates between 1.7% and 9% [2,[10][11][12][13][14] after implantation of the Intuity valve.…”
