Successful Percutaneous Coronary Intervention through a Severely Bent Artificial Ascending Aorta Using the DIO Thrombus Aspiration Catheter

Abstract EN

A 66-year-old man was admitted to our institute because of chest pain.

He had undergone replacement of the ascending aorta due to aortic dissection 9 years previously.

We made a diagnosis of acute coronary syndrome, and coronary artery angiography was performed.

Although the right coronary artery was successfully cannulated, a severe bend of the artificial aorta made it very difficult to advance the catheter into the left coronary artery.

Ultimately, a DIO thrombus aspiration catheter was used to enter the left coronary artery, and a stent was implanted successfully.

The DIO catheter is very useful when the selection of a guiding catheter is complicated, such as in the case of severe vessel tortuosity or a bend of the ascending aorta.
