Initial Clinical Experience with the New Irrigated Tip Magnetic Catheter for Ablation of Scar‐Related Sustained Ventricular Tachycardia: A Small Case Series
Key result
Radiofrequency ablation using a new irrigated tip magnetic catheter achieved acute success in 3 of 4 patients with electrical storm due to scar-related ventricular tachycardia.
Why the study?
Does radiofrequency ablation using a new irrigated tip magnetic catheter achieve acute success in patients with electrical storm due to scar-related VT?

Implication
May support feasibility in refractory VT storm; hypothesis-generating and should not change practice.

Structured PICO
Does radiofrequency ablation using a new irrigated tip magnetic catheter achieve acute success in patients with electrical storm due to scar-related VT?
P
Population
4 men (mean age 67.7 years) with ischemic heart disease, electrical storm, and an implantable cardioverter defibrillator, followed for a mean of 4.2 months.
I
Intervention
Radiofrequency ablation using a remote magnetic navigation system (MNS) and a new irrigated tip magnetic catheter.
O
Outcome
Acute success, defined as noninducibility of any monomorphic VT.surrogate
Irrigated ablation of scar-related VT guided by remote MNS appears feasible and effective for managing electrical storm in ischemic cardiomyopathy with minimal radiation exposure.
Cite This Study
Haghjoo et al. (2009) conducted a case report in Electrical storm due to scar-related ventricular tachycardia (n=4). Radiofrequency ablation using a remote magnetic navigation system and new irrigated tip magnetic catheter was evaluated on Acute success (noninducibility of any monomorphic VT). Radiofrequency ablation using a new irrigated tip magnetic catheter achieved acute success in 3 of 4 patients with electrical storm due to scar-related ventricular tachycardia.
