ABSTRACT

Clinical benefit of percutaneous coronary intervention (PCI) depends on both angiographic success at lesion site as well as the restoration of adequate macro and microvascular perfusion. The pathophysiology of embolization from coronary lesions during PCI is multifactorial, being more frequently observed in patients with acute coronary syndrome and in those with lesions at saphenous vein graft (SVG). In this population, despite successful epicardial intervention, distal tissue perfusion may still be absent in up to a quarter of all PCI. Multiple devices and pharmacologic regimens have been developed and refined in an attempt to protect the microvascular circulation during PCI. Among them, embolic protection devices have raised as an attractive adjunctive toll due to their ability to retain debris and potentially prevent distal embolization, reducing major adverse cardiac events. Currently, their use has been validated for the treatment of SVG lesions but failed to show effectiveness in the percutaneous approach of acute coronary syndrome patients, including those with ST elevation myocardial infarction.

ABSTRACT

A angina estável, forma mais comum de apresentação clínica da doença aterosclerótica coronária, ainda hoje responde por elevados índices de morbidade e mortalidade na população mundial, fato que continuamente tem estimulado os cardiologistas a pesquisarem novas formas de combatê-los, quer por meio do desenvolvimento de novos fármacos como do aprimoramento das técnicas de revascularização percutânea e cirúrgica. A Cardiologia intervencionista, ao longo de seus 25 anos de existência, vem oferecendo opções de tratamento percutâneo cada vez mais eficientes e menos invasivas para os portadores de doença coronária crônica, desde a era dos balões até os atuais stents eluídos em medicação, sendo hoje capaz de modificar de forma segura e eficaz a história natural dessa afecção.
