Getting AR patients the care they need
Aortic regurgitation (AR) is the third most common valvular pathology found in the general population, with a lifetime risk of 13% in men and 8.5% in women.1
It is critical to diagnose and treat AR early, as progression is associated with increased mortality risk. Within ten years of diagnosis of severe AR, 75% of patients die or require aortic valve replacement.1-4
Cardiologists play a key role in identifying AR and getting patients the care they need before it's too late.
AR prevalence increases with age
The Framingham Heart Study (1999) was a prospective epidemiological study that included the evaluation of the prevalence and severity of AR by color Doppler examination performed between 1991 and 1995.5
Progression of AR can be variable and exponentially increases mortality risk.2,3
Rates of progression are determined by a complicated interaction of several variables, including AR severity, aortic root pathology, and the adaptive response of the left ventricle (LV).6
Intervention is key to patient outcomes
According to guidelines from the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS), surgery is indicated in symptomatic severe AR regardless of left ventricle function. 10
Relying on symptoms alone may result in an intervention with poorer outcomes3,8
Even in asymptomatic severe AR, mortality can be as high as 19% within 6.6 years of diagnosis.
Echocardiography is the initial method of AR evaluation9-11
Multiple echocardiographic parameters are required to precisely quantify AR.11 Transthoracic echocardiography (TTE) is an essential first diagnostic test, and measurements obtained are frequently sufficient to evaluate the presence and severity of AR.9, 11
Echocardiography allows for the:
- Assessment of the motion of aortic leaflets and anatomy of the aortic root
- Detection of the presence and severity of AR
- Characterization of LV size and function11
An analysis of severe symptomatic AR (ssAR) patients and mortality
In an analysis of the Optum database from 2008-2016:
- Despite the class 1 indication for SAVR, most patients with ssAR do not receive treatment within one year12
- A patient’s primary cardiologist was a strong determinant of likelihood of receiving SAVR, particularly for patients with reduced LVEF12
An adjusted analysis showed patients who underwent SAVR had a 62% reduction in risk of 1-year mortality compared to patients who did not undergo surgery.12
The Heart Team builds on the foundation of the care you provide
All patients with severe valvular heart disease being considered for valve intervention should be evaluated by a multidisciplinary team with either referral to or consultation with a primary or comprehensive valve center.9
