Description
Junyi Chen and colleagues describe in 2026 a fully camera-guided way to redo mitral valve surgery on a beating heart, using high potassium to slow the heart rather than stop it. Repeat valve surgery usually means reopening the breastbone, a hazardous route through scar tissue. Their retrospective review compared 43 patients treated through a small right chest incision with 68 treated by conventional reopening, in cases from 2020 into 2026.
The camera group finished bypass and surgery faster, lost far less blood, and needed much less transfused blood and plasma. Drainage, ventilation time, intensive care stay, hospital stay, and total cost all fell, and pneumonia occurred less often. No deaths, strokes, or reoperations for bleeding occurred in the camera group, supporting the technique as safe in experienced hands.
