Abstract

I read with interest the study entitled “Effect of Pulmonary Hypertension Hemodynamic Presentation on Clinical Outcomes in Patients With Severe Symptomatic Aortic Valve Stenosis Undergoing Transcatheter Aortic Valve Implantation: Insights From the New Proposed Pulmonary Hypertension Classification.”1 The authors are to be congratulated on an admirably executed study. Multiple studies have shown that severe pulmonary hypertension (PH) is associated with worse outcomes after transcatheter aortic valve replacement (TAVR) for aortic stenosis.2,3 O’Sullivan et al1 classified patients with severe aortic stenosis undergoing TAVR according to the PH hemodynamics into those with …
