LV VAs.2 The complex relationships between the left ventricular summit (LVS) and surrounding structures under-score the importance of understanding the anatomy of this region and the .
The standard approach for mapping and ablation of LV summit arrhythmias has recently bee.
Premature ventricular contractions originating from the left ventricular (LV) summit pose a serious challenge to catheter ablation, as . Coronary venous ethanol ablation (VEA) can be used as a strategy to treat ventricular arrhythmias arising from the left ventricular summit, but collateral flow and technical . We performed stepwise catheter ablation on the LV-summit PVC origin site adjacent to severe coronary artery stenosis using a 3D electroanatomic mapping system in a .
LV VAs.2 The complex relationships between the left ventricular summit (LVS) and surrounding structures under-score the importance of understanding the anatomy of this region and the value of imaging techniques for detailed mapping and safe ablation. In this article, we review the anatomy of the LVS and our approach to mapping and Premature ventricular contractions originating from the left ventricular (LV) summit pose a serious challenge to catheter ablation, as myocardial thickness, epicardial fat, and coronary vessels impede appropriate radiofrequency (RF) energy delivery to the target areas. Coronary venous ethanol ablation (VEA) can be used as a strategy to treat ventricular arrhythmias arising from the left ventricular summit, but collateral flow and technical challenges cannulating intramural veins in complex venous anatomies can limit its use. We performed stepwise catheter ablation on the LV-summit PVC origin site adjacent to severe coronary artery stenosis using a 3D electroanatomic mapping system in a single case. Special precautions should be taken to avoid coronary artery damage during ablation from distal CVS.
lv annular vein ablation
Mapping using the coronary venous system helps differentiate intramural from epicardial LV summit sources. Early activation in the distal GCV or proximal anterior intraventricular vein (AIV) implicates the LV summit as the site of origin. Ablation of LVS arrhythmias may be performed at the septal right ventricular outflow tract (RVOT), the left coronary cusp, the LV myocardium beneath the left coronary cusp, the distal coronary sinus, and the great cardiac vein, as well as via the epicardial approach. ECG algorithms have also been developed to assist in distinguishing LV summit site that are outside the ablation inaccessible zone and within the more lateral accessible zone . An RBBB, TZ 1.1 and S wave in V 5 or V 6 predicted whether an LV summit OTVA could be ablated in the accessible area. 35
left ventricular summit arrhythmia ablation
The standard approach for mapping and ablation of LV summit arrhythmias has recently been reviewed.2 Here-in, we analyze in detail the anatomy of the LV outflow tract (LVOT), the mechanisms underlying these arrhythmias, and innovative approaches allowing a more detailed and accurate activation as well as pace and entrainment mapping in order to . LVS VAs can be eliminated by ablation from the coronary venous system or from adjacent endocardial structures, including the LCC, basal LV endocardium, or septal RVOT. Ablation from the endocardium is preferred when an intramural origin is suspected or when ablation from the GCV/AIV is unsafe because of close proximity to coronary vessel or not .
The guidewire was connected to an ablation catheter (Tacticath, Abbott) and generator (Ampere RF generator, Abbott) using alligator clips (Supplementary Figure 1). Four VINTAGE RF ablations , guided by impedance, were delivered to the LV summit accompanied by intramyocardial saline irrigation. During the second ablation, there was cessation of .LV VAs.2 The complex relationships between the left ventricular summit (LVS) and surrounding structures under-score the importance of understanding the anatomy of this region and the value of imaging techniques for detailed mapping and safe ablation.
