AbstractTranscatheter aortic valve replacement (TAVR) has become the preferred therapy for treatment of severe aortic stenosis in patients at intermediate to high risk of perioperative mortality following surgical aortic valve replacement. Haemodynamic assessment is an integral part of the procedure, and it is crucial for the operator to have an in-depth understanding of the haemodynamic alterations that occur during balloon aortic valvuloplasty and transcatheter valve deployment. Comprehension of the haemodynamic tracings is also pivotal for early recognition of periprocedural complications. With expanding indications for TAVR, it is imperative for members of the structural heart team to have an in-depth, nuanced understanding of transcatheter haemodynamic waveforms and their correlation with echocardiographic Doppler waveforms that are obtained periprocedurally during TAVR. This review provides a collection of transcatheter haemodynamic tracings and their corresponding Doppler echocardiography correlates that are demonstrative of physiological alterations and pathological lesions (complications) that occur during TAVR.
