Spontaneous left atrial haematoma

Life‐Threatening Left Atrial Wall Hematoma Secondary to a Pulmonary Vein Laceration: An Unusual Complication of Catheter Ablation for Atrial Fibrillation

“…Left atrial wall hematomas are rare. Only few studies reported their occurrence either spontaneously 2–4 or complicating a myocardial infarction 5 . To date, only three cases related to catheter ablation, including the present case, have been reported 6,7 .…”

Spontaneous dissecting aneurysm of the left atrium complicated by cerebral embolism: A report of two cases with review of literature

“…It can be caused by any cardiac interventions, including both surgical and catheter-based that involve manipulation of the LA. LA dissection is related to mitral valve surgery as well as coronary artery disease, arrhythmia, trauma, tumor, and spontaneous occurrence 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. Reported incidence rate following mitral valve surgery is 0.16% 1 .…”

“…In review of literature, 9 cases of spontaneous LA dissection without any intra-cardiac manipulations have been reported 4, 13, 14, 15, 16, 17, 18, 19, 20. Some of these spontaneous cases were attributed to underlying pathology including 3 cases of amyloid light-chain amyloidosis,15, 16, 19 2 cases of severe mitral annular calcification,4, 6 one case of infective endocarditis 20 and three were truly spontaneous without any known etiology.…”

“…Presentation may be early or delayed. Spontaneous dissection of the LA has been rarely reported in the literature 13, 14, 15, 16, 17, 18, 19, 20. We herein describe two patients, who presented with stroke and were found to have LA dissection with pseudo-aneurysm formation.…”

Left Atrial Intramural Hematoma after Removal of Atrial Myxoma: Cardiac Magnetic Resonance in the Differential Diagnosis of Intra-Cardiac Mass

“…We here present one rare case of LA dissection following removal of LA myxoma attached to the atrial septum. Even though LA dissection assessed by cardiac magnetic resonance imaging (CMR) has been previously reported, 11) 12) 13) this case report is unique in that 1) LA dissection with hematoma occurred after LA myxoma excision, and 2) CMR changed the diagnosis and finally guided management decision.…”
