Abstract

Expanding the Role of TAVR to Subaortic Membrane and LVOT Obstruction: A Commentary

Salem Assiri*

Subaortic Membrane (SAM) is a rare cause of fixed Left Ventricular Outflow Tract (LVOT) obstruction or Subaortic Stenosis (SAS). Surgical membrane resection has long been the mainstay of treatment. However, in elderly, inoperable or high-risk patients, this approach is often not feasible. Transcatheter Aortic Valve Replacement (TAVR), though not designed to address subvalvular pathology, has been explored in select cases with coexisting Aortic Stenosis (AS) and Subaortic Stenosis (SAS). This commentary discusses the emerging application of TAVR in managing Subaortic Stenosis (SAS), focusing on clinical rationale, procedural challenges, available evidence and the need for further research.
