AI Article Synopsis
- Impairment of left ventricular ejection is a rare but recognized complication following mitral valve replacement, especially with ball prostheses or standard bioprostheses in patients with small ventricles.
- Two recent cases highlighted this issue, where patients faced complications but were successfully re-operated on, one five weeks later and the other immediately after the initial surgery.
- A literature review supports the use of Doppler-sonocardiography for diagnosing this condition, emphasizing that prompt re-operation can reduce the risk of mortality linked to post-operative myocardial dysfunction.
Article Abstract
Impairment of the left ventricular ejection induced by a mitral prosthesis remains an infrequent complication, perhaps because it often is unrecognized. This complication would mainly be seen with ball prostheses or standard bioprosthesis used in mitral valve replacements with a small ventricle. Two cases have been recently reported during mitral valve replacement. The two patients were successfully re-operated upon, one after five weeks and the second immediately after the first procedure. A review of the literature enable to specify the etiology and diagnostic criteria with the assistance of Doppler-sonocardiography. Early re-operation may prevent death, often due to a post-operative myocardial dysfunction.
