Description
Kunaraj Perumalu and three colleagues describe, in a 2026 case, ablating a troublesome extra heartbeat buried deep inside the heart muscle wall, a location catheters struggle to reach. The origin was the posterior superior process of the left ventricle, an anatomically awkward corner.
Their patient, a 22-year-old woman with stimulant use disorder and methamphetamine-linked heart muscle disease, suffered disabling palpitations with extra beats making up nearly half of all heartbeats. Ultrasound imaging from inside the heart, fused with three-dimensional electrical mapping, guided precise burns and watched lesion depth in real time. No recurrence appeared during follow-up. The authors credit the imaging for safe contact and for spotting anatomical barriers.
