A summary of the article is shown below:

A 62-year-old man was referred to our institution for high-density, symptomatic PVCs with resultant decrease in LV function having failed prior ablation attempts. Successful, durable ablation of the patient’s mid-myocardial PVC arising from the LV summit region was achieved through the proximal great cardiac vein with ablation depth augmented by use of half-normal saline irrigant. Though standard ablation of ventricular arrhythmias using normal saline irrigation from the coronary venous system has been well-reported, this may be of limited value in addressing mid-myocardial sites of origin. This novel case describes the safe use of cooled radiofrequency ablation with use of half-normal saline irrigant from the distal coronary sinus as an option to address complex sites of PVC origin such as the LV summit.
