Implication
Antiarrhythmic therapy may suffice for inflammatory LV microaneurysm VT; extends observations on idiopathic arrhythmias but leaves open prospective validation.
Structured PICO
P
Population
156 consecutive patients (71 men, 85 women; mean age, 44.1+/-11.8 years) with severe ventricular arrhythmias and normal 2D echo cardiac parameters.
I
Intervention
Diagnostic evaluation including coronary and ventricular angiography, biventricular endomyocardial biopsy, and electrophysiological study, followed by antiarrhythmic therapy.
O
Outcome
Incidence, arrhythmogenic role, treatment, and prognosis of inflammatory left ventricular microaneurysms.
Inflammatory LV microaneurysms, often of viral origin, are a consistent cause of apparently idiopathic ventricular arrhythmias and have a benign prognosis with antiarrhythmic therapy.
