title: Cardiac calcified amorphous tumor in a patient presenting for ventricular tachycardia ablation: intracardiac echocardiogram diagnosis and management.
abstract: Calcified amorphous tumors (CAT) of the heart are rare primary cardiac tumors characterized by heavy myocardial and valve apparatus calcification. The relationship of the entity with ventricular arrhythmia, if any, is unknown. We describe a case of cardiac CAT in a 58-year-old woman with prior cardiac arrest and recurrent ventricular tachycardia who presented for radiofrequency ablation. Pre-ablation intracardiac echocardiogram revealed the characteristic endomyocardial calcific pattern associated with this tumor that precluded catheter manipulation in the left ventricle. The imaging characteristics and management are described.
