Why the study?
Does transoesophageal cross sectional echocardiography improve the visualization of left atrial appendage lesions compared to precordial echocardiography in a patient with a mitral valve prosthesis?
Does transoesophageal cross sectional echocardiography improve the visualization of left atrial appendage lesions compared to precordial echocardiography in a patient with a mitral valve prosthesis?
Transoesophageal echocardiography is superior to precordial echocardiography for visualizing left atrial appendage masses in patients with mitral valve prostheses.
Transoesophageal echocardiography may improve left atrial appendage mass detection in mitral prosthesis patients; leaves open confirmation in larger cohorts.
This report describes a patient with a Björk-Shiley mitral valve prosthesis in whom transoesophageal cross sectional echocardiography revealed a large vascularised mass within the left atrial appendage with smoke-like opacification of blood flow in the left atrium. Transoesophageal cross sectional echocardiography gave a detailed image of the lesion which was unobtainable with precordial cross sectional echocardiography.
