A new technique for measuring aortic root pressure during infusion of cardioplegic solution
WA Sievertsen, TD Hankins, HL Lazar, RF Davis and AJ Roberts
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.
