Key result
A 62-year-old woman developed marked hemodynamic and electrical instability due to right coronary artery spasm, apparently caused by compression from a chest drain tube following aortic valve replacement.
Case Report (n=1)
No
This case highlights that chest drain tubes can mechanically compress the right coronary artery, causing severe coronary spasm and hemodynamic instability after cardiac surgery.
Raises possibility of drain-induced coronary spasm in unstable post-AVR patients; leaves open optimal prevention strategies.
The authors present a clinical case of coronary artery spasm in a 62-year-old woman undergoing elective aortic valve replacement surgery for aortic regurgitation. On admission at ICU, the patient developed marked hemodynamic and electrical instability. Emergent coronary angiography demonstrated a pronounced spasm of the distal portion of the right coronary artery, apparently related to compression of this vessel by a chest drain tube.

Pinho et al. (2007) conducted a case report in Coronary artery spasm following aortic valve replacement (n=1). Chest drain tube compression was evaluated on Coronary artery spasm. A 62-year-old woman developed marked hemodynamic and electrical instability due to right coronary artery spasm, apparently caused by compression from a chest drain tube following aortic valve replacement.
