Prognostic Assessment of Fractional Flow Reserve in Different Strata in Patients with Coronary Artery Disease.

Background: There are limited real-world data on the clinical course of untreated coronary lesions according to their functional severity.

Objective: To evaluate the 5-year clinical outcomes of patients with revascularized lesions with fractional flow reserve (FFR) ≤ 0.8 and patients with non-revascularized lesions with FFR > 0.

Emergency Percutaneous Treatment of Saphenous Vein Graft Perforation After Cardiac Surgery.

Immediately post coronary artery bypass graft surgery, a 58-year-old woman developed excessive bleeding through the chest drains and hemodynamic instability, followed by total atrioventricular block requiring use of temporary pacemaker, which precluded electrocardiographic interpretation. She was referred for urgent diagnostic coronary angiography, which demonstrated important contrast leakage from the distal body of the saphenous vein graft to the first marginal branch. Acute saphenous vein graft perforation following coronary artery bypass graft surgery is rare.

Efficacy and safety of drug-eluting stents in the real world: 8-year follow-up.

Background: Drug-eluting stents have been used in daily practice since 2002, with the clear advantages of reducing the risk of target vessel revascularization and an impressive reduction in restenosis rate by 50%-70%. However, the occurrence of a late thrombosis can compromise long-term results, particularly if the risks of this event were sustained. In this context, a registry of clinical cases gains special value.
