Figure 4 Pullback Tracing From LV to LA Obtained With the Small Plastic Catheter

The patient had mitral stenosis with atrial fibrillation, and the left atrial (LA) tracing shows a pattern typical of mitral stenosis, with a delayed downslope of the V-wave and a large pressure gradient across the mitral valve. Reprinted with permission from Ross et al. (5). LV = left ventricle.
