The quick aortic turn: a rapid method for reformation of the Simmons sidewinder catheter

The Simmons sidewinder catheter is frequently used, but reforming its unique curve may be a problem. In our original description, we used the left subclavian artery to reform the catheter's curve. We no longer use this as our primary method of reformation. Our current method, which is simpler, quicker, and more reliably successful, is described.
