Invasive aortic valve assessment remains an essential cath lab procedure. The most widely used invasive technique for more than a decade has been performed with a Langston® Dual Lumen Catheter (Teleflex – Morrisville, NC), which has a 6Fr outer catheter and a 4Fr inner lumen enabling simultaneous measurement of left ventricular (LV) and aortic (AO) pressures.1 The catheter was recalled in March 2020 due to several instances of separation of the inner catheter during power injection.2, 3 This leaves cardiologists without a straightforward technique for simultaneously measuring LV and AO pressures in the cath lab. This Tip of the Month focuses on the various techniques available to perform an invasive aortic valve study.4–6
