Missed diagnosis of severe symptomatic aortic stenosis

Area of Science:

• Cardiology
• Cardiac diagnostics

Background:

• Angina pectoris and congestive heart failure (CHF) are common cardiovascular conditions.
• Systolic murmurs in patients with these conditions can indicate underlying valvular disease.
• Aortic stenosis (AS) is a critical valvular condition that requires timely diagnosis and management.

Purpose of the Study:

• To highlight the importance of suspecting significant aortic stenosis (AS) in patients presenting with angina pectoris and congestive heart failure (CHF).
• To identify specific patient demographics and clinical features associated with AS in this population.
• To recommend appropriate diagnostic imaging for confirming AS.

Main Methods:

• Clinical observation and analysis of patient cohorts presenting with angina and CHF.
• Review of electrocardiogram (ECG) findings, specifically the absence of left ventricular hypertrophy criteria.
• Emphasis on echocardiography for quantitative assessment of aortic valve area.

Main Results:

• Patients with angina and CHF, particularly women with atrial fibrillation and lacking ECG evidence of left ventricular hypertrophy, are frequently found to have significant AS.
• The presence of a systolic murmur is a key indicator for further investigation.
• Echocardiography provides crucial data for diagnosing and assessing the severity of AS.

Conclusions:

• A high index of suspicion for significant AS is warranted in patients with angina and CHF, especially those with specific demographic and clinical profiles.
• Electrocardiogram findings, or lack thereof, can provide clues but are not definitive for ruling out AS.
• Echocardiography, including the calculation of the aortic valve area, is the definitive diagnostic tool and should be performed in all patients suspected of having significant AS.
