Isolated right atrial rupture because of external cardiac massage after coronary artery bypass grafting

Background: Isolated right atrial rupture is a very rare catastrophic complication of cardiopulmonary resuscitation. Objective: We described a rare case of right atrial rupture after external cardiac massage. Methods: We reported the case of a 62-year-old male patient who developed excessive bleeding following external cardiac massage for sudden cardiac arrest in the intensive care unit after coronary artery bypass grafting. Results: This man underwent successful emergency repair of the tear of the right atrium without using cardiopulmonary bypass. Conclusion: Right atrial rupture can occur after external cardiac massage. An emergency repair is needed.
