TI  - Long-term follow-up after aortic valve replacement with a small aortic 
      prosthesis.
PG  - 245-8
AB  - Although aortic valve replacement (AVR) is an effective treatment for patients 
      with aortic valvular disease, the implantation of a small aortic prosthesis may 
      result in residual left ventricular outflow stenosis and transvalvular gradient. 
      In this study, the outcome in the long-term period of patients treated with a 
      small aortic prosthesis was analyzed retrospectively. Twenty-four patients with 
      AVR were divided into two groups, group A and group B. Group A consisted of 16 
      patients with 21 mm-sized prosthetic valves, and group B consisted of 8 patients 
      with 19 or 16 mm-sized prosthetic valves. There were no significant differences 
      in preoperative cardiac function or operative procedure in the two groups. The 
      mean follow-up period (months) was 55.0 in group A and 51.3 in group B. RESULTS: 
      One patient died of cerebral infarction in group A. There were no significant 
      differences in cardiothoracic ratio (CTR), left ventricular ejection fraction 
      (LVEF), and left ventricular mass index (LVMI) between the two groups. 
      Postoperative physical activity according to the New York Heart Association 
      (NYHA) classification showed no significant differences in the two groups. 
      Despite using a small prostheses for AVR, the postoperative course was good in 
      the long-term period, although careful follow-up is necessary.
