Another Complication of Peroral Endoscopic Myotomy

Peroral endoscopic myotomy is a safe and effective palliative procedure with acceptable known complications for achalasia. With its continuous practice, cardiac arrest secondary to tension pneumopericardium-induced tamponade is another adverse event coming to light. The authors present the case of a 72-year-old gentleman who suddenly went into pulseless electrical activity during the procedure with no other warning signs. Hemodynamic stability was achieved with urgent pericardiocentesis.
