Overview
Coronary angiography is used in the diagnostic evaluation of ventricular tachycardia in survivors of sudden cardiac death and life threatening ventricular tachycardia. Coronary angiography is used to rule out the presence of coronary artery disease in these patients.
Coronary Angiography
- Coronary angiography has an important role in diagnosis and treatment of myocardial ischemia-induced life-threatening VT, VF.
- Myocardial ischemia may induce recurrent polymorphic VT, or VF and is treatable by coronary revascularization.
- Evidence of ST segment elevation or early post resuscitated ECG changes suggestive of ischemia may lead to ventricular arrhythmia and sudden cardiac arrest and
required urgent revascularization.
- ST elevation can be present early after resuscitation due to DC shock and also coronary vasospasm.
- In the absence of ST elevation or other ECG changes, the obstruction of coronary arteries or thrombosis can not be excluded.[1]
- In patients with low evidence of myocardial ischemia, coronary angiography is not recommended.
- For patients suspected anomalous origin of the coronary arteries the may cause SCD , coronary angiography is warranted.
