Aortic valve replacement can mask chronic coronary artery occlusion. Stenting a collateral artery can lead to cardiac arrest, emphasizing the need to identify coronary collaterals and the Bezold-Jarisch reflex.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Cardiac Surgery
Background:
- Aortic valve replacement (AVR) is a common procedure for aortic valve disease.
- Coronary artery disease (CAD) can coexist with aortic valve disease.
- Late complications after AVR require careful consideration.
Observation:
- A 69-year-old woman experienced cardiac arrest post-circumflex artery stenting after AVR.
- Symptoms included hypotension, bradycardia, and cardiogenic shock.
- Postmortem examination revealed chronic right coronary artery occlusion.
Findings:
- The circumflex artery, acting as a collateral vessel, was jailed by stenting.
- This compromised collateral flow led to ischemic events.
- The Bezold-Jarisch reflex may have contributed to the hemodynamic instability.
Implications:
- Accurate definition of coronary collaterals is crucial before coronary interventions.
- Suspect late coronary occlusion following AVR, especially with atypical presentations.
- Recognize the Bezold-Jarisch reflex in patients with hemodynamic compromise after cardiac procedures.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
