Description

Yosuke Nakatani and colleagues describe a 2026 technique paper on heart ablation in patients with a small left atrium. The Varipulse system uses a ring catheter to isolate the pulmonary veins, which can trigger irregular heartbeats. Keeping that ring steady against the back wall of the right veins is hard in a small chamber.

The authors lay out a four-step method that combines sheath bending, full ring expansion, partial withdrawal, and a clockwise turn. These moves set the ring nearly parallel to the sheath shaft. A smaller turning radius follows, so the ring sits flat and stable against its target. Clinicians facing tight anatomy gain a simple, repeatable workaround.
