The majority of sudden cardiac deaths, which are predominantly due to acute coronary events, occur out of hospital. Rarely, resistant ventricular fibrillation, pulseless electrical activity (PEA) or asystole occur during cardiac catheterization. In such cases, the underlying coronary event should be immediately defined by coronary angiography and percutaneous coronary intervention performed as appropriate (PCI). Lethal ventricular<unk> s have been reported to occur in 1.5-4% of patients undergoing PCI. In the Primary Angioplasty in Myocardial Infarction (PAMI) trial, ventricular<unk> s occurred in 4.3% of patients.
PCI in the patient with refractory ventricular arrhythmia

PCI in the patient at risk of bleeding
PCI in the angulated or tortuous lesion
PCI in the patient with in stent restenosis
Intervention in left main coronary artery disease
