Surgical Revascularization in Patients with ”Ischemia-related” Ventricular Fibrillation: Is It Sufficient to Prevent Sudden Death?
Acute ischemia is a major contributing factor in sudden cardiac death attributable to ventricular fibrillation [1, 2]. Surgical revascularization is a generally accepted treatment for acute ischemia. However, the role of revascularization in secondary prevention for the survivors of cardiac death is controversial [3, 4]. In the presence of acute ischemia as the only causative factor in the arrhythmia, revascularization has proved very effective in the case of critical narrowing of at least one coronary artery . If narrowing is due to coronary spasm, however, calcium blockers and ICD implantation are the preferred therapies. Polymorphic ventricular tachycardia and ventricular fibrillation are the typical arrhythmias caused by acute ischemia.
