“…13 CUSA technique employs ultrasonic waves to disintegrate calcium and the resulting debris can be extracted without causing damage to adjacent structures. 21,22,23 In conclusion, CCMA are entities that are rare and underrecognized variants of MAC, which need to be distinguished from common differentials such as intra-cardiac tumors, myocardial abscesses, thrombus 9 or cyst. 20…”

Caseous calcification of the mitral annulus (CCMA) is a rare form of periannular calcification, occurring in 0.06% of all echocardiographic studies and in 0.63% of all patients with mitral annular calcification. Here, we report a case of CCMA manifesting as a left atrial mass. The patient is a 78-year-old African American female with multiple co-morbidities, who presented with symptomatic coronary artery disease and chest pain. A pre-operative echocardiogram revealed a mass in the posterior wall of the left atrium, which did not appear to affect the mitral valve or protrude into the left atrial chamber. Intra-operatively, white toothpaste-like material was removed from the mass lesion. Gross examination revealed multiple fragments of grey-white friable caseous material, measuring 3 x 2.5 x 1 cm in aggregate. Bacterial and fungal cultures from this material were both negative. Microscopic examination showed this material to be amorphous, non-viable, basophilic, and acellular, with foci of calcification. These morphological features were diagnostic for CCMA. Review of the literature indicated that CCMA is a very rare benign lesion, presenting as a round, tumor-like mass with central echolucencies on echocardiography. We believe our case report will further raise the awareness of CCMA so that pathologists and radiologists can get familiar with this rare disease to avoid potential misdiagnosis.

“…Surgical treatment in such a case is technically difficult. There is need for adequate debridement and annular reconstruction prior to mitral valve repair or replacement [8,9] . Mitral valve repair may not be technically feasible in such cases because of severe calcification and the difficulty of suturing at the calcified site, mandating a prosthetic valve replacement.…”

Severe mitral annular calcification (MAC) is frequently seen in patients with advanced age and chronic kidney disease, but it is rare in rheumatic heart disease (RHD). We hereby report a case of 45�year�old female with chronic RHD, who had severe MAC and mitral regur� gitation�� luoroscopy revealed a "crown"�like severe calcification of the mitral annulus. Autopsy of the heart revealed a calcified posterior mitral annulus, fused commissures, and calcified nodules at the atrial aspect of the mitral valve��

“…Alternative techniques using the non-excised remnants of the posterior leaflet, in cases where the calcification and the abscess are outside the leaflet attachment, are not applicable to all situations. 10 Nomura and colleagues 11 have recently described an alternative technique using ultrasonic surgical aspiration in the debridement of calcium, before annulus reconstruction with equine pericardium.…”

Abscess resection and prosthesis reimplantation is the only effective treatment for mitral prosthesis endocarditis with extensive annular abscess, but it has high morbidity and mortality when associated with severe mitral annular calcification in the atrial and ventricular walls. We describe a technique that allows repair of the abscess cavity, reconstruction of the annulus, and implantation of a new mitral prosthesis when there is severe adjacent myocardial calcification, so decreasing the reoperation risk.
