Description
Balaji Krishnan and three colleagues recount in 2026 how an extra strand of tissue inside the heart nearly cost a patient his life. Ventricular fibrillation with no structural cause explains a slice of cardiac arrest survivors, and stray early beats are often the trigger. In this patient those beats arose where a false cord, a fibrous band, anchored from the tricuspid valve ring to the right ventricular wall.
The authors reason that muscle fibers inside the band either fire spontaneously or grow excitable where mechanical tugging strains the attachment. Because sedatives easily silence right-sided trigger beats during procedures, they used pace mapping, stimulating candidate spots to mimic the guilty beat's signature. Imaging from inside the heart guided the ablation before, during, and after. Freeing the trigger and treating the surrounding substrate, they report, can deliver lasting freedom from arrhythmia.
