Aortic valve type and calcification as assessed by transthoracic and transoesophageal echocardiography

Introduction Aortic valve calcification (AVC) may predict poor outcome. Bicuspid aortic valve (BAV) leads to several haemodynamic changes accelerating the progress of aortic valve (AV) disease. Aims To compare the diagnostic accuracy of transoesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in the assessment of aortic valve phenotype and degree of AVC, with intra-operative evaluation as a reference. Methods We examined...
