title: A new technique for measuring aortic root pressure during infusion of cardioplegic solution.
abstract: Aortic root pressure is an important factor in determining the distribution of cardioplegic solutions. Previously, in order to measure this parameter, it was necessary to insert a separate catheter into the aortic root during cardioplegic infusion. An alternative method for measuring aortic root pressure is described that is both simple and accurate and obviates the need for a second aortic root catheter.
