摘要：In the early years of coronary interventions,when a single lesion was found,the question then was asked whether it was feasible and safe to dilate right away the lesion with plain old balloon angioplasty (ad hoc POBA) or to call in a senior interventional cardiologist to do POBA on a later *** lesions were found in more than one coronary artery territories,then the interventional cardiologists had to pull his or her hair and asked whether it was feasible and safe to dilate right away the other lesion(s) at the same *** than 20 years later,at this present time,with nearly perfect outcomes due to stent availability and high level of experiences from operators,the question of multiple coronary stenting in one session is neither problematic nor ***,if not all lesions are taken care immediately or in near future sessions,the question would be whether the patient receives standard of care as there is no complete revascularization.
