Percutaneous approaches to structural heart disease have become increasingly available and have supplanted many traditional surgical approaches. Cardiac CT has evolved into a critical, standard-of-care imaging modality for both pre-procedural planning and post-procedural assessment.
It provides exceptional 3D spatial resolution that is frequently superior to traditional 2D echocardiography for evaluating complex, non-circular geometries — the aortic annulus, the LAA, the pulmonary vein ostia.
The articles in this group cover the four procedures where CT is mandated up front:
- TAVR planning — annulus sizing, coronary ostia heights, iliofemoral access, co-planar angles
- LAA occlusion planning — Watchman / Amplatzer / Lariat sizing and post-procedure surveillance
- Pulmonary vein mapping — pre-ablation roadmap for atrial fibrillation
- Congenital heart disease overview — when CT is the preferred advanced modality
