Primary Percutaneous Coronary Intervention of Acute Thrombotic Occlusion of a Low-Lying Tortuous Right Coronary Artery With a Multipurpose Catheter in an Octogenarian.

Right coronary artery intervention is usually accomplished with a Judkins right (JR) coronary guide catheter. Abnormal right coronary artery take-off from the right coronary sinus poses difficulty in engaging the right coronary artery with a conventional JR guide catheter. We report a rare case of primary percutaneous intervention of the right coronary artery which was performed with a multipurpose catheter as the patient had an extremely low-lying coronary artery from the coronary sinus where conventional catheters could not engage the right coronary artery in an octogenarian with acute inferior wall ST-elevation myocardial infarction in cardiogenic shock.
