OBJECTIVE: This study aims to analyze the success of the ultrasonic aspirator to excise calcification during mitral valve replacement while also investigating variables which alter the success rate of these procedures.
METHODS: A retrospective chart review was completed on 19 patients with severe mitral calcification requiring ultrasonic aspirator use prior to mitral valve replacement. Survival rates were determined by utilizing Kaplan-Meier curve. Multivariate regression will be used to determine factors conferring to higher success and significant associations leading to complications. This study reflects an interim analysis of a larger database.
RESULTS: Mortality was determined to be highest within first seven post-operative days and patients were not likely to experience complications outside of this window. Of the complications reported, none were related to debris from mitral valve. Factors which conferred to a higher rate of post-operative mortality were concurrent aortic stenosis and peri-operative complications. Severity of mitral calcification, severity of mitral valve stenosis, and degree of mitral regurgitation did not correlate with a higher risk of complication post-operatively.
CONCLUSIONS: Calcified valves pose a difficult challenge during valve replacement and can lead to various complications. Identifying techniques to successfully excise calcifications would confer a higher success rate for valve replacement.
