Accurate resting blood pressure plays an important role in the accurate calculation of flow-dependent valvular indices used to grade the severity of valvular disease using echocardiograph images. If resting blood pressure is over-estimated there is a potential for error in the diagnosis of valvulopathies and by extension, an over or under treatment of valvular disease. Therefore, there is a need to improve concordance between various non-flow dependent indices, such as AVA and Dimensionless Index (DI), and flow dependent indices by using the patient’s average resting BP or trough BP. It is still not known at what time point during the course of the study the patient achieves their resting BP. This research study hopes to investigate that.

Exclusion Criteria

  • Adults unable to consent (cognitively impaired adults)
