4D-transesophageal echocardiography and emerging imaging modalities for guiding mitral valve repair.

摘要: Two-dimensional transesophageal echocardiography (2D-TEE) had a transformative impact on surgical treatment of mitral valve pathology in the 1980s. 2D-TEE provided unprecedented, high-quality views that enabled pre-operative repair strategizing and immediate post-operative assessment efficacy. Several decades later, commercialization four-dimensional (4D-TEE) other emerging imaging modalities such as 4D computed tomography (4DCT) cardiac magnetic resonance (CMRI) potentiate yet another phase practice surgery. Bypassing “mental integration” step required for 2D image interpretation, these higher dimensional provide more intuitive, complete description morphology dynamics can be leveraged tool effective decision support. Current research shows may enhance outcomes four ways: (I) by increasing precision diagnostics order to tailor plan an individual’s pathology; (II) means risk stratification determine which patients might benefit from over replacement; (III) predicting outcome given technique using image-derived models input computational biomechanical analysis; (IV) optimizing annuloplasty ring design. Research highlights each areas are below.
