Isolated left atrial appendage ostial stenosis

Isolated left atrial appendage ostial stenosis.

A patient with atrial tachycardia presented with dyspnoea on exertion. Transoesophageal echocardiography revealed idiopathic left atrial appendage stenosis. The mouth of the atrial appendage was narrowed, and there was a high velocity to and fro jet between the left atrial body and the left atrial appendage. The study, therefore, suggested isolated left atrial appendage orifice stenosis.

Left atrial appendage ostial stenosis associated with rheumatic mitral stenosis \

Isolated left atrial appendage (LAA) stenosis is a very rare entity that is almost always detected coincidentally with transesophageal echocardiography (TEE). The clinical consequences of this condition are still unknown, but thrombus formation is likely to occur in the narrowed area. A 51-year-old female was admitted to an outpatient clinic due to the complaint of dizziness. Physical examinati...

Left Atrial Appendage Ostial Stenosis in a Patient with Atrial Flutter and Asymmetric Septal Hypertrophy

Left atrial appendage ostial stenosis with or without previous surgicalor catheter-based intervention has been previously described [1-5]. The clinical implications of this anomaly are uncertain because it’s a very rare condition given the small number of cases reported. Herein, we report a case of left atrial appendage ostial stenosis with typical atrial flutter (AFL) and asymmetric septal hyp...

Case images: Left atrial appendage ostial stenosis in a patient with rheumatic mitral valve disease.

A 45-year-old female was admitted to the outpatient clinic with complaint of dyspnea on exertion. Cardiac examination revealed a diastolic murmur best heard at apex, but was otherwise unremarkable. Transthoracic echocardiography and transesophageal echocardiography (TEE) revealed moderate mitral and aortic regurgitation with severe rheumatic mitral stenosis (Video 1*). TEE revealed left atrial ...
