Delayed spontaneous recanalization of chronic total occlusion of left anterior descending artery after attempted but failed revascularization during percutaneous coronary intervention

Abstract

Chronic total occlusion (CTO) of coronary artery remains the Achilles heel of the interventional cardiologist and is present in a significant proportion of referrals for coronary artery bypass graft surgery (CABG); however, with the development and standardization of modern CTO recanalization techniques, it has been able to achieve excellent success while coping with lesions of increasing complexity. Nevertheless, failure to recanalize despite the development of new techniques still remains one of the challenges in the field of interventional cardiology. Spontaneous recanalization has been described in nonocclusive coronary artery dissections in detail; none has addressed the possibility of spontaneous recanalization after failed percutaneous coronary intervention (PCI). We report a case of spontaneous but delayed recanalization of CTO of left anterior descending artery 3 years after attempted but failed revascularization during PCI.

Evaluation of Oxidative Status in Elderly Patients with Multiple Cerebral Infarctions and Multiple Chronic Total Coronary Occlusions

“…The numbers of patients with MCI+OVCL, MCI+TVCL, and MCI+MVCL were 230, 222, and 213, respectively. The patients with MCI+chronic total coronary occlusions defined as 100% obstruction of a coronary artery [ 12 ] were included in MCI+one-vessel coronary occlusion (OVCO) group ( n = 59), MCI+two-vessel coronary occlusion (TVCO) group ( n = 57), MCI+multiple-vessel coronary occlusion (MVCO) defined as three-vessel coronary occlusions [ 13 ] group ( n = 54), unilateral multiple cerebral infarcts (UMCI)+OVCO group ( n = 57), bilateral multiple cerebral infarcts (BMCI)+TVCO group ( n = 55), BMCI+MVCO group ( n = 53), multiple lacunar cerebral infarcts (MLCI)+OVCO group ( n = 57), multiple cerebellum infarcts (MCBI)+TVCO group ( n = 55), MCBI+MVCO group ( n = 53), multiple cerebral microinfarcts (MCMI) (≤4 mm)+OVCO group ( n = 57), multiple small cerebral infarcts (MSCI) (diameter < 15 mm)+TVCO group ( n = 55), and multiple large cerebral infarcts (MLCI) (diameter ≥ 15 mm)+MVCO group ( n = 53).…”
