NINO, Santiago et al. Malignant arrhythmia in mitral valve prolapse: is surgical management enough?. Rev. Colomb. Cardiol. [online]. 2024, vol.31, n.3, pp.169-173.  Epub July 29, 2024. ISSN 0120-5633.  https://doi.org/10.24875/rccar.24000006.

Mitral valve prolapse is a well-known condition that is generally benign, but it can be associated with cardiac arrhythmias, particularly malignant ventricular arrhythmias and sudden cardiac death. This association and its outcome have been described in medical literature, but the low incidence leads to a lack of evidence regarding its management and stratification.The case of a young woman is presented, whose initial manifestation was syncope, with subsequent development of severe mitral insufficiency, followed by severe mitral regurgitation and the discovery of frequent ventricular extrasystoles. She underwent surgical repair with mitral valve plasty and cryoablation of the anterior papillary muscle. The clinical outcome was favorable, as evidenced by an improvement in symptoms and control of arrhythmia burden.
