What is the prevalence and clinical significance of mitral annular disjunction in patients with mitral valve prolapse?
Mitral annular disjunction is present in over a third of patients with mitral valve prolapse, highlighting the need for standardized multimodality imaging and serial monitoring for ventricular arrhythmias.
MAD was present in more than one-third of MVP patients, with a wide range of variability depending on the specific imaging method used for assessing MAD presence and on a nonunivocal MAD definition, with a possible overestimation due to Pseudo-MAD rather than True-MAD measurement. A multimodality imaging approach comprehensive of noninvasive chest shape assessment might improve MAD detection among MVP individuals. It appears that careful serial monitoring for VAs should be mandatory for MAD patients.
