76828 Doppler echocardiography, fetal, pulsed wave and/or continuous wave with spectral display; follow-up or repeat study

Name of the Procedure:

Doppler Echocardiography, Fetal, Pulsed Wave and/or Continuous Wave with Spectral Display; Follow-up or Repeat Study

Summary

Doppler echocardiography for fetus is a non-invasive imaging test that uses ultrasound waves to evaluate the heart and blood flow in a developing baby. This follow-up or repeat study ensures ongoing monitoring of fetal heart health by using pulsed wave and/or continuous wave techniques to create detailed images and measure blood flow.

Purpose

Doppler echocardiography is used to assess the heart and blood vessels of a fetus. It helps in diagnosing congenital heart defects, abnormal blood flow patterns, and other cardiac conditions. The follow-up or repeat study aims to track any changes or developments since the initial examination, ensuring the health and proper development of the fetal heart.

Indications

• Suspected congenital heart defects.
• Abnormal results from initial fetal echocardiography.
• Family history of heart disease.
• Abnormal findings from other pregnancy ultrasounds.
• Maternal conditions like diabetes or lupus impacting the fetus.

Preparation

• No fasting required.
• Continue any medications as prescribed unless advised otherwise by the doctor.

• Inform the healthcare provider about any relevant medical history or complications.

  Procedure Description

  1. The pregnant mother lies down on an examination table.
  2. A water-based gel is applied to the abdomen to improve sound wave transmission.
  3. A transducer (ultrasound wand) is moved over the abdomen to capture images.
  4. Pulsed wave and/or continuous wave techniques are used to measure blood flow.
  5. Spectral display graphs show how blood moves through the fetal heart and vessels.
  6. The procedure typically does not require sedation or anesthesia and is painless.

  Duration

  The procedure typically takes about 30 minutes to an hour.

Setting

Performed in a hospital, outpatient clinic, or specialized imaging center.

Personnel

• Perinatologist or Pediatric Cardiologist: Physicians specialized in fetal and pediatric heart conditions.
• Sonographer: Trained to operate the ultrasound equipment and capture images.
• Nurses: Assist with the procedure and provide patient care.

Risks and Complications

• Very low risk, as it is a non-invasive procedure.
• Rarely, mild discomfort due to the pressure of the transducer.
• No known risks of ultrasound exposure to the fetus.

Benefits

• Early and accurate detection of fetal heart anomalies.
• Allows for better planning and management of birth and possible interventions.
• Increased peace of mind for expecting parents with detailed information on fetal heart health.

Recovery

• No recovery period needed.
• Patients can resume normal activities immediately after the procedure.
• Follow-up appointments as scheduled based on the findings.

Alternatives

• Standard prenatal ultrasounds: Less detailed for cardiac-specific concerns.
• MRI: Occasionally used but not as detailed for dynamic blood flow analyses in the fetus.
• Wait until birth for detailed echocardiography if no urgent concerns present.

Patient Experience

• The patient may feel slight pressure as the transducer is moved over the abdomen.
• Generally painless and does not require any recovery time.
• Ultrasound gel might feel cold, but this is temporary.
• Communication with the healthcare provider throughout ensures comfort and understanding of the process.
