  • Title: [Hemolytic anemia due to aortic valve regurgitation after mitral valve replacement].
    Author: Iwaki H, Kuraoka S, Tatebe S.
    Journal: Kyobu Geka; 2003 Feb; 56(2):124-8. PubMed ID: 12635322.
    Abstract:
    A 50-year-old woman was admitted to our hospital because of heart failure (NYHA III) due to mitral valve regurgitation (MR) with pulmonary hypertension (PH) and tricuspid valve regurgitation (TR). She had a history of chronic renal failure undergoing dialysis (peritoneal dialysis, homodialysis) since 1996. Cardiac catheterization and ultrasonic cardiography showed severe MR (Sellers III), severe TR and PH (mean pressure 33 mmHg). So we performed mitral valve replacement and tricuspid annuloplasty (DeVega). Frequent blood transfusion was needed because severe hemolytic anemia appeared after operation. Ultrasonic cardiography demonstrated moderate aortic valve regurgitation (AR) with no paravalvular prosthetic leakage. We diagnosed hemolytic anemia due to AR. We performed aortic valve replacement. Hemolytic anemia improved soon after second operation. We investigated the mechanical process of the AR. She had a very short subaortic curtain (5.9 mm) compared with the average (8.7 +/- 2.1 mm: mean +/- SD) of cardiac patients. We think that we must be very careful with suture to short subaortic curtain. In addition measurement of subaortic curtain before operation is very useful.
