Severe Aortic Regurgitation After Transradial Percutaneous Coronary Intervention

Abstract

A 60-year-old man presented to a community hospital with new-onset shortness of breath after a 2-hour episode of typical chest pain. The ECG showed anteroseptal and inferior wall Q-waves. Serum troponin T levels were negative. An echocardiogram revealed anterior wall hypokinesia with left ventricular ejection fraction of 40% and no signs of valvular disease. The patient was transferred to our center for coronary angiography. Arterial access was obtained from the right radial artery. The angiogram showed mild disease of the left coronary artery and a right coronary artery (RCA) arising from the left coronary sinus. The RCA was extremely difficult to cannulate; nonselective injections revealed a long and severe stenosis of the mid segment (Figure 1 and Movie 1). After many unsuccessful attempts to cannulate the RCA with different guiding catheters, the operator decided to engage first the left coronary artery with an Amplatz 2 guiding catheter. A BMW Universal II guide wire was advanced into the left anterior descending artery (LAD) for better stability. This approach …
