TI  - Comparison of the effects of aortic valve replacement using 19-mm 
      Carpentier-Edwards Perimount bioprosthesis and 19-mm Medtronic Mosaic 
      bioprosthesis.
PG  - 81-7
AB  - OBJECTIVE: Short (< or =3 months)- and middle (> or =4 months)-term results of 
      aortic valve replacement (AVR) using 19-mm Carpentier-Edwards Perimount (CEP) 
      bioprosthetic valves and 19-mm Medtronic Mosaic (MM) bioprosthetic valves in 
      patients with small aortic annulus were compared. PATIENTS AND METHODS: At our 
      facility, AVR was performed using bioprostheses in 110 patients from April 1999 
      to March 2006. Of these patients, 40 were treated using 19-mm CEP (Group C), and 
      9 using 19-mm MM (Group M). Evaluation by inquiry, physical examination, and 
      echocardiography was performed before, a short term after, and a middle term 
      after surgery, and the effects of AVR were compared. RESULTS: The New York Heart 
      Association (NYHA) functional class grade showed improvements in both groups. The 
      aortic valve peak pressure gradient was 29.8 +/- 10.1 mmHg in Group C and 53.8 
      +/- 17.3 mmHg in Group M, being higher in Group M, a middle term after surgery. 
      However, the left ventricular mass index (LVMI) showed improvements in both 
      groups compared with the values before surgery, and the left ventricular ejection 
      fraction (LVEF) was maintained. During the middle term after surgery, the 
      frequency of cardiac events showed no significant difference between the two 
      groups. CONCLUSIONS: In the patients treated with 19-mm MM, the aortic valve peak 
      pressure gradient was higher than in those treated with 19-mm CEP, but acceptable 
      improvements in the LVMI, maintenance of the LVEF, and avoidance of cardiac 
      events were observed in both groups.
