Ventricular Fibrillation during Optical Coherence Tomography

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Optical Coherence Tomography (OCT) is essential for complex coronary interventions.
• Ventricular arrhythmias are a rare but significant feared complication during OCT procedures.

Observation:

• A patient undergoing OCT experienced ventricular fibrillation (VF) while under continuous electrocardiographic (ECG) monitoring.
• The study details the ECG sequence from contrast administration to the onset of VF.

Findings:

• Analysis of the ECG data identified potential precipitating factors for VF during OCT.
• Observed electrocardiogram alterations were examined in relation to contrast medium administration.

Implications:

• Understanding the mechanism of OCT-induced arrhythmias is crucial for patient safety.
• Developing preventive strategies is essential to mitigate the risk of these adverse events during cardiac procedures.
