Name of the Procedure:

Common Name(s): Left Ventricular Ejection Fraction (LVEF) Assessment
Medical Term: Documentation of Left Ventricular Systolic Function, Indicator <40% (G8934)

Summary

The left ventricular ejection fraction (LVEF) assessment measures how much blood the left ventricle of the heart pumps out with each contraction. An LVEF of less than 40% or a documented moderately to severely depressed left ventricular systolic function is an indication of heart conditions that need medical attention and management.

Purpose

Medical Conditions Addressed:

• Heart failure
• Cardiomyopathy
• Myocardial infarction (heart attack)

Goals/Outcomes:

• Diagnose or confirm heart conditions
• Assess the severity of heart dysfunction
• Guide treatment plans and interventions

Indications

Symptoms/Conditions:

• Shortness of breath
• Fatigue
• Swelling in legs or ankles
• Irregular heartbeat

Patient Criteria:

• Patients with suspected or known heart disease
• Individuals showing symptoms of heart failure

Preparation

Pre-procedure Instructions:

• No special preparation is needed for most non-invasive tests
• Follow doctor's instructions on medication adjustments if applicable

Diagnostic Tests:

• Echocardiogram (often required to measure LVEF)
• Blood tests
• Electrocardiogram (ECG)

Procedure Description

Steps:

1. Echocardiography: The patient lies on an exam table.
2. A technician applies gel to the chest and uses an ultrasound transducer to capture images of the heart.
3. The images are analyzed to calculate the LVEF.

Tools and Equipment:

• Ultrasound machine with transducer
• Electrodes and ECG machine (if needed for monitoring)

Anesthesia/Sedation:

• Generally not required for non-invasive tests

Duration

• The echocardiogram procedure takes about 30 to 60 minutes.

Setting

• Performed in a hospital, outpatient clinic, or cardiac care center.

Personnel

• Cardiologist or specialized physician
• Ultrasound technician or sonographer
• Nurses or medical assistants

Risks and Complications

Common Risks:

• For non-invasive tests, there are minimal risks.

Possible Complications:

• Rarely, allergic reaction to the gel used in the echocardiogram
• Minor discomfort from the transducer pressure

Management:

• Immediate medical attention for allergic reactions

Benefits

• Accurate assessment of heart function
• Early diagnosis of heart conditions
• Improved management and treatment outcomes

Realization of Benefits:

• Usually immediate after analysis of the test results

Recovery

Post-procedure Care:

• No special care needed for non-invasive tests
• Resume normal activities immediately

Expected Recovery Time:

• Instantaneous for non-invasive tests

Follow-up Appointments:

• Based on findings, patients may need further tests or regular follow-ups with their cardiologist

Alternatives

Other Treatment Options:

• Radionuclide ventriculography
• Magnetic resonance imaging (MRI)
• Cardiac catheterization

Pros and Cons:

• Some alternatives may provide different types of information or be more invasive

Patient Experience

During the Procedure:

• Mild pressure on the chest from the transducer
• Comfortable, generally painless

After the Procedure:

• No significant discomfort
• Regular activities can be resumed immediately

Pain Management and Comfort Measures:

• Distraction techniques like listening to music during the process if anxious
