Intraoperative determination of the aortic valve area (Gorlin) by flowmetry.
The aortic area (Torlin) for diseased stenotic aortic valves was calculated in 10 patients using two different methods; data obtained in preoperative cardiac catheterization and by intraoperative flowmetric and aortic and left ventricular pressure-recording measurements, and their mutual correlation was tested. The correlation between the aortic valve areas obtained by these methods was very good (r = 0.992), confirming the valve and reliability of the intraoperative flowmetric and pressure recording measurements in clinical work.
