Dissecting Aneurysm of Left Atrium Following External Cardiac Massage

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

“…It is postulated that this anatomical difference accounts for the tendency of occurrence of LA dissection on the posterior wall in patients undergoing mitral valve surgery Aside from mitral procedures, aortic valve replacement, 5 coronary artery bypass grafting, 6 left ventricular aneurysmectomy, 7 pulmonary vein cannulation 8 and cardiac mass excision 9 have been associated with LA dissection. There have been non-cardiac surgical aetiologies described in the literature, including myocardial infarction, percutaneous coronary intervention 11 ], radiofrequency ablation, 12 infective endocarditis, 20 and blunt cardiac trauma 21, 22. LA dissection due to radiofrequency ablation may be caused by creation of an endocardial flap of the LA wall due to a stiff wire manipulation.…”

Atrial Dissection‐Like Appearance Caused by Ileus Due to Metastatic Renal Cell Carcinoma

“…1 It is generally associated with mitral valve surgery; 2 however, blunt chest trauma, 3 acute myocardial infarction 4 and infective endocarditis 5 have been also reported as etiology. An intimal flap of the atrial wall has been accepted as a diagnostic criterion of atrial dissection.…”

“…Atrial dissection is an uncommon entity, defined as a gap from the mitral or tricuspid annular area to the interatrial septum or left atrial wall, creating a new chamber with or without communications into the true left or right atrium. 1 It is generally associated with mitral valve surgery; 2 however, blunt chest trauma, 3 acute myocardial infarction 4 and infective endocarditis 5 have been also reported as etiology. An intimal flap of the atrial wall has been accepted as a diagnostic criterion of atrial dissection.…”
