Suri et al. [] conducted an RCT from 2004 to 2006 examining 76 Edwards Perimount bovine and 76 MM Porcine valves. Despite small differences in haemodynamic performance, both valves had similar LV regression after 1 year follow-up.

The Edwards SAPIEN 3 transcatheter heart valve will be placed on the delivery system and compressed on a balloon. The delivery system carrying the valve will be placed through the sheath and delivered to your aortic valve. The balloon of the delivery system will be inflated, expanding the new valve within your diseased valve.

Dalmau et al. [] performed an RCT in Spain comparing 43 MM porcine valves with 43 Edward Perimount Magna bovine valves in AVR position. Mean pressure gradient, EOA and LV mass regression were examined. Bovine valves showed better haemodynamic function with lower patient–prosthesis mismatch prevalence at 1-year follow-up.

Czer et al. [] conducted a cohort study on 656 patients comparing Hancock standard and CE porcine valves with St Jude Medical bileaflet bovine valves in AVR, MVR or MR positions from 1976–1984. Both porcine and bovine valves had a similar mortality rate. Porcine valves had higher structural failure rates with higher reoperation rates. Bovine valves showed better functional status postoperatively.

Casabona et al. [] completed a cohort study comparing 27 stentless porcine/bovine valves with 30 Omnicarbon mechanical valves/stented porcine Biocor bioprosthesis. They also made comparisons between two stentless valves, which showed no difference in postoperative aortic valve area, maximum velocity across the valve and mortality.

Eichinger et al. [] conducted an RCT comparing 68 MM porcine valve and 70 CE Perimount bovine valves in AVR in the years 2000 to 2002. There was no difference in patient–prosthesis mismatch. The bovine valve had lower mean pressure gradient at rest and during exercise 10 months after operation.

Aortic valve replacement: is porcine or bovine valve better?

Reichenspurner et al. [] compared Carpentier-Edwards (CE), CE Supra-annular, Hancock first and second generation porcine valves in 423 patients and Hancock-Extracorporeal, Ionescu-Shiley, CE, Mitroflow bovine valves in 577 patients in AVR, mitral valve (MVR) or multiple valve (MR) positions from 1978 to 1990. The freedom rate from thromboembolic complications was significantly lower in bovine valves. The long-term results of primary tissue failure and long-term survival rates were significantly better in porcine valves.

In a cardiac surgery clinic, you are consulted by a 70-year old gentleman with aortic stenosis who is referred for AVR. The patient has searched the web and wonders whether a porcine or bovine valve is better. As a consultant cardiac surgeon you decide to review the literature to resolve this question. You specifically want to know the survival, clinical outcomes and complication rates of these valves in AVR.

Heart Valve Replacement Failures & Infections

These valves are intended for use in patients whose aortic valvular disease is sufficiently advanced to warrant replacement of their natural valve with a prosthetic one. It is also intended for use in patients with a previously implanted aortic valve prosthesis which is no longer functioning adequately and requires replacement. Valve replacement can include the following risks:

Borger et al. [] performed a cohort study comparing 57 Medtronic Hancock II porcine valves with 57 CE Perimount Magna bovine valves in AVR and/or concomitant procedures in 2004 to 2005. Bovine valves showed better peak and mean transvalvular gradients with lower patient–prosthesis mismatch.

The Edwards SAPIEN XT transcatheter heart valve and accessories are also indicated for patients with symptomatic heart disease due to failure (stenosed, insufficient, or combined) of a surgical bioprosthetic aortic valve who are judged by a heart team, including a cardiac surgeon, to be at high or greater risk for open surgical therapy (i.e., STS operative risk score ≥8% or at a ≥15% risk of mortality at 30 days).
