The left ventricular summit (LVS) anatomy plays a crucial role in various cardiac procedures, especially in ventricular tachycardia (VT) ablation and mapping. Delineating the LVS venous anatomy is essential for successful procedures and optimal patient outcomes. In this article, we will delve into the intricate details of LV summit anatomy, focusing on selective venography, 3D mapping, and venous-phase coronary computed tomographic angiography (vCTA).
Where is LV Summit Located?
The LV summit refers to the area at the apex of the left ventricle, near the aortic root and mitral valve. It is a critical region for mapping and ablation procedures, as it is often the site of origin for ventricular arrhythmias.
Aorto-Mitral Continuity and LV Summit Anatomy
The aorto-mitral continuity is the region where the aortic valve leaflets merge with the mitral valve leaflets. This area is closely related to the LV summit anatomy, as the proximity of the aortic and mitral valves influences the electrical pathways and arrhythmogenic foci in the left ventricle.
VT Ablation Map and LV Summit Anatomy
During VT ablation procedures, creating a detailed map of the left ventricle is crucial for identifying the origin of the arrhythmia and delivering targeted therapy. The LV summit plays a significant role in VT ablation mapping, as it is often a high-frequency site for VT origins.
LV Summit PVC Morphology
Premature ventricular contractions (PVCs) originating from the LV summit can have distinct morphologies on electrocardiogram (ECG). Understanding the PVC morphology associated with the LV summit can aid in localization and ablation of the arrhythmic focus.
Left Ventricle Ablation and LV Summit
Ablation procedures targeting the left ventricle often involve navigating complex anatomical structures, including the LV summit. Precise mapping and ablation at the LV summit are essential for successful outcomes in patients with refractory ventricular arrhythmias.
Ablated High Point in LV Summit Anatomy
Identifying and ablating the high points in the LV summit can be challenging due to the intricate venous anatomy and proximity to critical structures. Careful mapping and ablation techniques are required to achieve optimal results in VT ablation procedures.
