Purpose:
The aim of this study was to investigate the primary echocardiographic results of aortic valve replacement using 21- and 19-mm Carpentier-Edwards Perimount Magna bioprosthesis aortic xenografts in patients with small aortic annulus.
Methods:
Twenty patients (mean body surface area 1.63 ± 0.16 m(2)) underwent aortic valve replacement between June 2008 and December 2009. Eight and 12 patients received 21- and 19-mm Magna bioprostheses, respectively. After 12 months, hemodynamic data were obtained by echocardiography to estimate the prosthesis-patient mismatch.
Results:
At follow-up, significant decreases in peak and mean left ventricular aortic pressure gradients were observed in the 12 patients with aortic stenosis (P < 0.05). Regression of the left ventricular mass was observed in all the patients (P < 0.05). The mean measured effective orifice area (EOA) and EOA index (EOAI) were 1.61 ± 0.28 cm(2) and 0.99 ± 0.16 cm(2)/m(2), respectively. Prosthesis-patient mismatch (EOAI ≤0.85) was documented in three patients.
Conclusion:
The primary echocardiographic findings suggested that the hemodynamic performance of the 19- and 21-mm Carpentier-Edwards Perimount Magna bioprostheses was satisfactory in the patients with a small aortic annulus.
