Mechanical Discordance between Left Atrium and Left Atrial Appendage
نویسندگان
چکیده
During standard transesophageal echocardiographic examinations in sinus rhythm (SR) patients, the left atrial appendage (LAA) is not routinely assessed with Doppler. Despite having a SR, it is still possible to have irregular activity in the LAA. This situation is even more important for SR patients where assessment of the left atrium is often foregone. We describe a case where we encountered this situation and briefly review how to assess the left atrium and its appendage in such a case scenario.

Mechanical discordance of the left atrium and appendage: a novel mechanism of stroke in paroxysmal atrial fibrillation.
BACKGROUND AND PURPOSE Thromboembolism in paroxysmal atrial fibrillation (AF) has often been attributed to occult AF. We hypothesized that the surface ECG may not always reflect left atrial appendage (LAA) mechanical function. METHODS Transesophageal echocardiographic images from 201 consecutive patients undergoing transesophageal echocardiography by a single operator were reviewed. LAA pulse...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

Myxoma is the most common type of primary tumors of heart. Recurrence of nonfamilial myxoma is unusual and recurrence in left atrial appendage is not reported. We present a case of sporadic myxoma in the left atrium who had a successful resection. However, the patient’s constitutional symptoms caused confusion and difficulty in diagnosis. Final diagnosis was recurrent Myxoma in the left atri...

96 A 54-year-old man was referred to our center for assessment after an episode of syncope and progressive dyspnea. Clinical examination and echocardiography revealed dextrocardia with situs inversus, and bilateral basal crepitations without bruits. Plain chest films disclosed only an increased cardiothoracic index. Transthoracic echocardiography provided incomplete information on cardiac anato...

OBJECTIVE Facing the hypothesis of participation of mechanical stress as a cause of mitral bioprosthesis dysfunction, we decided to assess the relation of preservation of the texture of the mitral bioprosthesis leaflets with left ventricular function, in addition to the casual formation of thrombus in left atrium in patients with left ventricular dysfunction from the implant of mitral bioprosth...
