Cardiac hemangioma is a rare benign tumor of the heart. We report here on a case of cardiac hemangioma that originated from the left atrial appendage; this was observed on the CT and coronary angiographic findings and the lesion was pathologically proved.

BACKGROUND: After left atrial appendage (LAA) device closure, peri-device leakage into the LAA persists due to incomplete occlusion. We hypothesized that pre-procedural three-dimensional (3D) geometric analysis of the interatrial septum (IAS) and LAA orifice can predict this leakage. We investigated the predictive parameters of LAA device closure obtained from baseline cardiac computerized tomography (CT) using a novel 3D analysis system. METHODS: We conducted a retrospective study of 22 patients who underwent LAA device closure. We defined peri-device leakage as the presence of a Doppler signal inside the LAA after device deployment (group 2, n = 5) compared with patients without peri-device leakage (group 1, n = 17). Conventional parameters were measured by cardiac CT. Angles theta and phi were defined between the IAS plane and the line, linking the LAA orifice center and foramen ovale. RESULTS: Group 2 exhibited significantly better left atrial (LA) function than group 1 (p = 0.031). Pre-procedural theta was also larger in this group (41.9degrees vs. 52.3degrees, p = 0.019). The LAA cauliflower-type morphology was more common in group 2. Overall, the patients' LA reserve significantly decreased after the procedure (21.7 mm3 vs. 17.8 mm3, p = 0.035). However, we observed no significant interval changes in pre- and post-procedural values of theta and phi in either group (all p > 0.05). CONCLUSION: Angles between the IAS and LAA orifice might be a novel anatomical parameter for predicting peri-device leakage after LAA device closure. In addition, 3D CT analysis of the LA and LAA orifice could be used to identify clinically favorable candidates for LAA device closure.
