“…The spectrum of LAtD presentation depends on the extent of atrioventricular junction injury disruption and the direction of the dissecting blood: in the published reports, surgical treatment has been used in majority of patients ( 8 ) because LAtD may evolve in acute exsanguinating hemorrhage, hematoma, or prosthesis leak or may encroach onto the adjacent structures and can progress toward occlusion of LA cavity, pulmonary veins or mitral inflow obstruction, pulmonary artery hypertension, and right heart failure. There are case reports describing acute LAtD after MV replacement surgically treated for their hemodynamic instability, as well as cases of deferred surgery for paravalvular leak with progression to heart failure ( 7 , 9 , 10 ).

Left atrial dissection is a rare entity mostly associated with mitral valve surgery and revealed in early post-operative period. This case report discusses a case of left atrial dissection associated with dislocation of the mechanical mitral prosthesis in the left atrium, which was peculiar in its anatomy and pathophysiology, occurred 12 years after surgery. ( Level of Difficulty: Advanced. )

Non-iatrogenic left atrial wall dissection is a rare lesion defined as a gap from the mitral valve annulus to the interatrial septum or wall of the left atrium. We report the case of a 57-year-old man with symptoms of acute cardiac and renal failure. Transesophageal echocardiography and computed tomography showed significant mitral valve regurgitation and dissection of the posterior wall of the left atrium. On the basis of detailed trans-esophageal echocardiography, the patient underwent mitral valve replacement with closure of the dissection orifice, which appears to be the appropriate therapeutic strategy in cases of spontaneous left atrial wall dissection.

Background: Left atrial dissection is an extremely rare complication of mitral valve replacement. Because of its severity, its prompt diagnosis and treatment is mandatory. The most effective treatment (i.e. surgical vs. nonsurgical) for left atrial dissection has not been fully established yet. Case presentation: Herein, we have reported left atrial dissection after mitral valve replacement in a 68-year-old obese woman. After closing the thorax, transesophageal echocardiography (TEE) revealed an atrial mass of 3 cm × 2 cm, visualized as an oval hypoechoic appearance extending from the posterior annulus of the mitral valve to the posterior wall of the left atrium. Because hemodynamic conditions were stable, surgery was ruled out and conservative treatment with close observation was selected. On postoperative day 2, TEE revealed that the atrial mass had vanished and the broken piece of the endocardium merely remained fluttering in the atrium. On postoperative day 6, the appearance of the left atrium was normalized completely, leaving no traces of left atrial dissection. The patient recovered uneventfully. Serial TEE was a very effective imaging modality during the nonsurgical treatment of left atrial dissection. Conclusions: It is crucial to accurately define diagnosis and optimally consider therapeutic strategies for left atrial dissection based on the hemodynamic conditions of the patient and serial TEE follow-up examinations. In our case study, left atrial dissection was successfully treated with conservative treatment; therefore, we believe that TEE could be a feasible modality for the early diagnosis of this condition.
