We report a rare case of dense mitral annular calcification in a 26-year-old male presenting with recurrent palpitation for the last year with a plethora of mitral annular premature ventricular complexes (PVCs). PVCs had right bundle branch block morphology, were notched in inferior leads with negative QRS complexes in aVL suggestive of likely origin from the lateral mitral annulus. Patients with PVCs from mitral annulus are usually advised to undergo cardiac magnetic resonance imaging to localize the site of subtle mitral annular calcification and plan subsequent delivery of radiofrequency lesions at the same site during radiofrequency ablation. Dense calcification of the lateral mitral annulus is extremely rare to encounter in such a young age of below 30 years without the presence of any predisposing risk factors for calcification. Our case is the first illustration of dense mitral annular calcification secondary to the plethora of mitral annular PVCs in a symptomatic young person below the age of 30 years. PVCs-induced excessive local excursion with wear and tear phenomenon and secondary dystrophic calcification may be the plausible explanation behind this interesting presentation.
