Consensus recommendations

Use of 3D mapping in ventricular tachycardia: Idiopathic outflow tract tachycardia
Recommendation	Class	LOE	References
In pediatric or pregnant patients, 3D mapping systems are recommended to avoid or minimize radiation exposure.	I	C‐LD	249, 251
Due to the complex anatomy of the outflow tract, the primary use of a 3D mapping system is recommended in all OT‐VT that do not stem from the RVOT.	I	C‐LD	256, 260
In case of recurrent RVOT‐VT the use of a 3D mapping system is reasonable.	IIa	C‐EO

3D, three‐dimensional; OT, outflow tract; RVOT, right ventricular outflow tract; VT, ventricular tachycardia.
