Real-time 3D trans-esophageal echo (TEE) is being integrated into routine clinical practice for minimally invasive cardiac therapy. Electromagnetically (EM) tracking of the TEE probe inside the body may facilitate intraprocedural heart surgery and therapy on a beating heart. This requires an accurate calibration between the 3D TEE and the EM tracking system. The objective of calibration is to find...
Pre-surgical planning of mitral valve (MV) repair in patients with Barlow's disease (BD) and fibroelastic deficiency (FED) is challenging due to inability to accurately assess the complexity of MV prolapse. We hypothesized that the etiology of degenerative MV disease (DMVD) could be objectively and accurately determined using morphologic analysis of MV geometry from real-time 3D echocardiographic...
Mitral valve (MV) repair is the preferred treatment for mitral regurgitation associated with organic MV prolapse (MVP). Our goal was to describe the dynamic changes in mitral annulus (MA) geometry after annuloplasty, using custom software for MA tracking from transthoracic real-time 3D echocardiography (RT3DE). Forty-four MVP patients, divided into 2 subgroups (RIG and FLEX), were studied by RT3DE...
Mitral valve (MV) repair is the preferential treatment for mitral regurgitation (MR) associated with degenerative MV disease, and the functional benefits of early surgery are known. Our goal was to evaluate the changes in LV shape following MV repair, using a new method based on real-time 3D echocardiography (RT3DE). Fifty patients with severe asymptomatic MR were enrolled. Transthoracic RT3DE imaging...
