Background Understanding complex cardiac anatomy is essential for percutaneous left atrial appendage (LAA) closure. Conventional multi-slice computed tomography (MSCT) and transesophageal echocardiography (TEE) are now supported by advanced 3D printing virtual reality (VR) techniques three-dimensional visualization of volumetric data sets. This study aimed to investigate their added value LAA closure procedures. Methods Ten patients scheduled interventional were evaluated with MSCT TEE. Patient-specific printings VR models fabricated based on data. cardiologists then comparatively assessed its procedure relevant surrounding structures all four imaging modalities rated procedural utility a 5-point Likert scale questionnaire (from 1 = strongly agree 5 disagree). Results Device sizing was highest in (MSCT: 1.9 ± 0.8; TEE: 2.6 0.9; printing: 2.5 1.0; VR: 1.1; p < 0.01); TEE, VR, superior the Fossa ovalis compared 3.3 1.4; 2.2 1.3; 0.01). The major strength depth perception (VR: 1.6 0.5; 1.8 0.4; 2.9 0.7; MSCT: extracardiac less accurate TEE than (TEE: 0.8, However, insufficiently visualized present study. Conclusion A true or provides an additional evaluation planning In particular, seen as visualization. may contribute better overall understanding anatomy. Clinical studies needed evaluate whether more comprehensive through multimodal patient-specific using translate into improved outcomes.
