Avoid torque and pass through the central portion of valve annulus or chordae tendineae when using multipolar mapping catheters to prevent tricuspid valve and papillary muscle rupture.
When using multipolar mapping catheters, operators should pass through the central portion of the valve annulus and avoid applying torque to prevent entrapment and rupture of valve structures.
