Low-Flow Aortic Stenosis

ULTRASOUND SOLUTIONS CORP. is pleased to welcome back Ian Crandall, MS, RCS, FASE, HVC Quality and Safety Education Coordinator, from Yale New Haven’s Heart and Vascular Center Echocardiography Laboratory for an exciting discussion on how to recognize and evaluate Low-Flow Aortic Stenosis.

Course Description:

Aortic Stenosis (AS) is routinely diagnosed by echocardiography. Hemodynamic severity can be defined by Doppler echocardiographic measurements of maximum transvalvular velocity and the mean transaortic gradient, as well as with the calculation of valve area by using the continuity equation. Severe AS is defined by an aortic valve area (AVA) <1.0 cm², a peak aortic valve velocity >4 m/s, and/or a mean aortic valve gradient >40 mm Hg. Nevertheless, severe AS can be present in patients with low forward flow, resulting in a peak valve velocity <4 m/s and a mean aortic valve gradient <40 mm Hg. This entity is the so‐called low‐flow/low‐gradient AS (LF/LGAS). (Approved for 1 SDMS CME credit, provided one is present for the entire event)

Course Objectives: Upon completion of this educational activity, the participant will be able to:

• Define low-gradient aortic stenosis.
• Differentiate between the different types of low-gradient aortic stenosis.
• Review hemodynamic terms associated with each subtype of low-gradient aortic stenosis.
• Review the algorithm for diagnosis and work-up of low-gradient aortic stenosis.

About Our Speaker:

Ian Crandall, MS, RCS, FASE, is the HVC Quality/Safety Education Coordinator at Yale New Haven Health System. His main responsibilities are to develop, organize, implement, and evaluate site-based/service line education and programs to ensure competencies of Sonographer personnel across the health system.

With over 10 years of experience in the field, Ian is known for performing a wide variety of technical and professional duties at the highest level for all procedures and equipment across all platforms. As a Sonographer, he took on additional responsibilities in research and education within the healthcare system. Ian now works with Administrators, Physicians, Sonographers, and associated staff to support performance and quality improvement. He does this by identifying Sonographer learning needs and facilitating the process for learners to assume responsibility for maintaining competency in practice. Ian is known for developing effective formal and informal educational programs that meet learning needs and achieve desired outcomes.

Ian holds a Master of Science degree in Exercise Science, along with a Bachelor of Science degree, both from Southern Connecticut State University. He completed his training in Adult Cardiac Ultrasound at the Hoffman Heart and Vascular Institute at St. Francis Hospital.

This activity is an approved SDMS CME activity – approved for 1.0 SDMS CME credit.

Please note that partial credit will not be issued.

The CME participant roster will be reported by Ultrasound Solutions Corp. to the

SDMS CME Tracker System.

Important update from the SDMS:

SDMS no longer allows its CME providers to issue Partial Credit for attendance. If you join late or leave early, the SDMS will no longer permit us to award partial pro-rated credit.

Therefore, from now on, in order to receive CME credit, you must be in attendance for the ENTIRE event via your own unique Zoom link that Zoom emailed to you when you registered. Then, and only then, will USC be able to award you any credit. So, please be prompt and attentive to the time schedule. We apologize for any inconvenience, but again, this is a new SDMS policy we must abide by. Thank you for understanding.
