Popis: | Severe mitral annular calcification (MAC) increases surgical complexity and is independently associated with increased operative mortality for mitral valve replacement (MVR). Recently we adopted ultrasonic emulsification/aspiration for annular decalcification to address these risks and describe our early experience with this new technology.Excluding previous mitral valve surgery or endocarditis, 179 patients with MAC underwent MVR at a single institution between January 2015 and March 2020. Of these, 15 consecutive patients with severe MAC (≥50% of the annulus) underwent annular decalcification with ultrasonic emulsification/aspiration as an adjunct treatment during MVR from April 2019 to March 2020.Mean patient age was 68 ± 12 years, and 72% (n = 128) were female. Mean preoperative left ventricular ejection fraction was 60% ± 11%, and mean mitral valve gradient was 9.1 ± 4.4 mm Hg. Concomitant procedures included antiarrhythmia (n = 52), aortic valve replacement (n = 32), and coronary artery bypass grafting (n = 20). There were no operative deaths or strokes in the group undergoing ultrasonic emulsification and aspiration.The use of ultrasonic emulsification and aspiration in severe MAC patients may help mitigate the risks of MVR and facilitate operative success in this challenging, high-risk population. |
