The number of percutaneous coronary interventions (PCI) performed worldwide is increasing. With the improvement of technology and interventional tools, the number of procedures is expected to further increase. As the range of equipment available to t…
Within a decade of coronary artery bypass graft surgery, 50% of saphenous vein grafts fail, causing recurrent angina and acute coronary syndromes.1 Because of the substantial risk associated with re-operation, percutaneous intervention is often prefe…
Coarctation of the aorta (CoA) accounts for 6–8% of all forms of congenital heart defects. In children and adults, balloon angioplasty has become the preferred treatment for patients with recurrent CoA.1–5,6–18 The application of this technique for t…
The primary goal of therapy for acute myocardial infarction (AMI) is rapid, complete and sustained restoration of infarct-related artery (IRA) blood flow and myocardial perfusion, with a consequent positive impact on the patient’s outcome. Both fibri…
Since Robert Goetz first performed a single mammary artery bypass to the anterior descending artery in 1960, its evolution has been associated with unparalleled clinical benefit in terms of symptom relief and a favorable effect on mortality, particul…
Myocardial injury after percutaneous coronary interventions has been recognized as a frequent and prognostically important event.1 Multiple institutions have now reported follow-up studies of percutaneous revascularization, and the evidence supports…
Transradial coronary percutaneous procedures are associated with reduced entry site complications compared to transfemoral or transbrachial techniques.1–4 However, the transradial approach is technically more challenging and time-consuming,4 which ex…
The no-reflow phenomenon is defined as a severe reduction in antegrade coronary flow in the absence of epicardial vessel obstruction.1 The presence of no-reflow substantially increases the risk of major adverse clinical events (MACE) in percutaneous…
Proximal left anterior descending artery (LAD) stenoses are considered to have special prognostic implications.1 Medically treated patients with isolated proximal LAD stenosis have a significantly worse prognosis than patients with lesions in other l…
Percutaneous intervention of saphenous vein grafts is associated with approximately 20% risk of major adverse cardiovascular events secondary to decreased antegrade flow or “no-reflow” during the procedure.1 The mechanism of this phenomenon is probab…
