Doppler echocardiography in elderly patients with ejection systolic murmurs

Area of Science:

• Cardiology
• Geriatric Medicine
• Diagnostic Imaging

Background:

• Ejection systolic murmurs are common in elderly patients.
• The functional significance of these murmurs requires careful evaluation to rule out significant valvular heart disease.
• Aortic stenosis is a critical condition that can be underdiagnosed in this population.

Purpose of the Study:

• To evaluate the functional significance of ejection systolic murmurs in elderly patients.
• To determine the prevalence of significant aortic stenosis in this demographic.
• To assess the diagnostic accuracy of clinical evaluation and 2-D echocardiography compared to Doppler echocardiography.

Main Methods:

• Study included 39 elderly patients (mean age 77 years) with ejection systolic murmurs.
• Comprehensive evaluation included clinical assessment, 2-D echocardiography, and Doppler echocardiography.
• Doppler echocardiography was used to measure transvalvular gradients and assess valvular lesions.

Main Results:

• Significant aortic stenosis (Doppler gradient >30 mmHg) was found in 7 subjects (20%).
• Mitral regurgitation was the only significant valvular lesion in 6 patients (17%).
• Clinical assessment had 44% sensitivity and 81% specificity for detecting significant aortic stenosis.

Conclusions:

• A substantial proportion of elderly patients with ejection systolic murmurs have significant aortic stenosis.
• Clinical assessment and 2-D echocardiography are insufficient to exclude significant aortic stenosis.
• Doppler echocardiography is essential for accurate diagnosis and management of valvular heart disease in the elderly.
