Severe Coronary Vasospasm with Extensive Myocardial Necrosis and Refractory Ventricular Fibrillation

Key Result

Multimodality imaging confirmed severe coronary vasospasm as the primary mechanism underlying acute coronary occlusion in a patient with refractory ventricular fibrillation and cardiac arrest.

Key Points

• This case explores the relationship between severe coronary vasospasm and its consequences, including myocardial injury and ventricular fibrillation.
• Used angiography to assess coronary arteries for stenosis and occlusion.
• Examined clinical features associated with severe coronary events.
• Detected moderate stenosis in the right coronary artery (RCA) and left anterior descending artery (LAD).
• Observed sudden occlusion of the LAD leading to myocardial damage.
• Documented refractory ventricular fibrillation in the patient.
