Double transseptal catheterization guided by real-time 3-dimensional transesophageal echocardiography

Monitoring and guiding cardiac interventions and surgery

“…Fig. 12.16) [109][110] [111]. Recently, RT3D TEE has been demonstrated in several clinical studies to provide superior 3D visualization of all pulmonary vein ostia and neighboring left atrial structures during ablation and to provide the operator successful guidance to position an ablation c atheter or cryoballoon in the pulmonary veins [112] [113] [114].…”

Three-dimensional Echocardiography

“…Pirat et al [111] performed an in vitro validation study of 3D reconstruction of the PISA surface based on manual tracing of the isovelocity surface contour in eight radial planes and found more accurate estimates of aortic regurgitant volume when compared to 2D methods which was most pronounced in noncircular orifices.

A Comparison of Echocardiographic Modalities to Guide Structural Heart Disease Interventions

“…44 While there are no case series using RT3D-TEE for percutaneous MVBV, reports of RT3D-TEE for transseptal puncture procedures in electrophysiology highlight the potential utility of RT3D-TEE in percutaneous MVBV in completing the transseptal puncture as well as navigating catheters within the left atrium. 13,14 Conversely, RT3D-TEE has reduced spatial and temporal resolution compared to 2D ultrasound with occasional loss of the sharp delineation of target structures. Furthermore, visualization of the interatrial septum using RT3D-TEE during transseptal catheterization can often be disorienting and it is common to revert to the adjustable 2D biplane imaging to guide puncture.…”

“…In addition, RT3D‐TEE is capable of immediate identification of complications, such as differentiating between leaflet tears and commissural splitting as the mechanism of increased mitral leaflet mobility postballoon dilation 44 .
