Comparison of myocardial tissue reperfusion of inferior wall and a right ventricle among patients after primary angioplasty for an inferior myocardial infarction with right ventricular infarction.

Background: Impaired myocardial tissue reperfusion affects prognosis of patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) and can be identified by ST-segment analysis. To date, evaluation of the myocardial tissue reperfusion of the right ventricle (RV) among the patients treated with PCI for inferior STEMI with right ventricular infarction (RVI) has not been made yet.

Methods: Patients with inferior STEMI were screened for RVI.

Importance of Right Marginal Branch Protection During Primary Angioplasty in Inferior STEMI With Right Ventricular Involvement.

We document the high effectiveness of an extra guidewire insertion aimed at mechanical lumen protection of the right marginal branch from displaced thrombus, which frequently occurs during proximal right coronary artery stenting.
