Cardiac Resynchronization Therapy Device (CRT-D)

A Cardiac Resynchronization Therapy Device with Defibrillator (CRT-D) is an advanced medical device implanted in the chest to help manage heart failure and other serious heart conditions. A CRT-D combines cardiac resynchronization therapy and defibrillation to improve heart function, prevent life-threatening arrhythmias, and enhance the quality of life for individuals with weakened heart muscles.

Signs & Symptoms

Symptoms suggesting CRT-D may be necessary often relate to heart failure and arrhythmias:

Persistent shortness of breath.
Fatigue or weakness.
Swelling in the legs, ankles, or abdomen.
Irregular or rapid heartbeat.
Difficulty performing everyday activities due to tiredness.
Dizziness or fainting.

Causes

Conditions that may lead to CRT-D consideration include:

Coronary artery disease (CAD): Blocked arteries can weaken the heart.
Cardiomyopathy: Enlarged or damaged heart muscle.
Congenital heart defects: Heart abnormalities present at birth.
Electrolyte imbalances: Irregular levels of potassium or calcium.
Previous heart attack: Damage from a heart attack can disrupt electrical signals in the heart.

When to seek medical attention?

If you experience any of the following, you should consult a cardiologist:

Persistent chest pain or pressure.
Frequent dizziness or fainting spells.
Difficulty breathing when lying down.
Swelling in the legs or abdomen that worsens.
Irregular heartbeats that feel like flutters or pounding.

Diagnostics & Tests

Several tests help determine if a CRT-D device is appropriate:

Echocardiogram (Echo): Assesses heart muscle function and synchronization.
Electrocardiogram (ECG or EKG): Monitors electrical activity for irregularities.
Stress Test: Evaluates heart performance under stress.
Blood tests: Check for cardiac enzymes and other indicators of heart health.
Cardiac MRI or CT scan: Provides detailed images of the heart's structure.

Do’s & Don’ts

Do’s

Follow-up appointments: Keep regular check-ups to monitor device performance.
Limit arm movement initially: Avoid strenuous arm activities for several weeks.
Take prescribed medications: To support heart health and prevent complications.
Report symptoms: Inform your doctor of any unusual symptoms, like fainting or dizziness.

Don’ts

Avoid strong magnets or electrical fields: These can interfere with the CRT-D.
Refrain from high-impact activities: Avoid sports that could damage the device.
Skip scheduled battery checks: The battery will need periodic monitoring and eventual replacement.
