What to Expect Before, During, and After CRT Implantation

Cardiac Resynchronization Therapy (CRT) is a revolutionary treatment for individuals suffering from heart failure due to uncoordinated heartbeats. This procedure uses a specialized pacemaker to improve the heart’s efficiency, reducing symptoms like fatigue, breathlessness, and fluid retention. If you or a loved one is scheduled for CRT implantation, understanding what to expect before, during, and after the procedure can help ease any concerns and prepare for a smooth recovery.

Before CRT Implantation

Consultation and Evaluation

Your journey to cardiac resynchronization therapy begins with an in-depth evaluation by your cardiologist. This typically includes:

• Medical History Review – Your doctor will assess your medical background, medications, and previous treatments.

• Diagnostic Tests – These may include an electrocardiogram (ECG), echocardiogram, and stress tests to determine the extent of heart dysfunction and eligibility for CRT.

• Imaging and Additional Assessments – Advanced imaging techniques such as cardiac MRI or CT scans may be used to evaluate heart structure and function.

Preparation Steps

Once your doctor confirms that CRT is the right approach, preparation for the procedure begins. You may be advised to:

• Adjust Medications – Some medications, such as blood thinners, may need to be modified before the procedure.

• Follow Dietary Guidelines – Fasting for several hours before surgery may be required.

• Arrange Support – You will need someone to drive you home after the procedure and assist you for the first few days of recovery.

During CRT Implantation

The Procedure Overview

CRT implantation is a minimally invasive procedure that generally takes two to four hours. It is typically performed under local anesthesia with sedation to keep you comfortable.

1. Incision and Lead Placement

   • A small incision is made near the collarbone to access a major vein.

   • Three leads (thin insulated wires) are guided through the veins to different chambers of the heart.

   • These leads send electrical impulses to synchronize the heart's contractions.

2. CRT Device Placement

   • The CRT device, also called a biventricular pacemaker, is placed under the skin, usually below the collarbone.

   • The device is connected to the leads, ensuring proper electrical stimulation.

3. Testing and Closure

   • The cardiologist tests the device to confirm correct functionality.

   • Once satisfied, the incision is closed with sutures, and a bandage is applied.

Throughout the procedure, doctors closely monitor heart activity using fluoroscopy (a type of real-time X-ray) to ensure precise lead placement.

After CRT Implantation

Immediate Recovery

Post-procedure, you will be taken to a recovery room for observation. You may experience mild discomfort or swelling at the incision site. Most patients are discharged within 24 to 48 hours, depending on their overall health.

First Few Weeks

• Activity Restrictions – Avoid heavy lifting, strenuous activities, and excessive arm movements for the first four to six weeks to allow the leads to settle in place.

• Medication Management – Continue prescribed heart failure medications as directed by your doctor.

• Incision Care – Keep the area clean and dry to prevent infections. Contact your doctor if you notice redness, swelling, or unusual pain.

Follow-Up and Monitoring

• Regular Check-Ups – Your cardiologist will schedule follow-up visits to assess device function and make necessary adjustments.

• Device Optimization – Over time, doctors may fine-tune the CRT settings to maximize heart function.

• Remote Monitoring – Some CRT devices allow for remote tracking, helping physicians monitor your condition without frequent hospital visits.

Long-Term Benefits and Lifestyle Changes

How CRT Improves Quality of Life

Patients who undergo cardiac resynchronization therapy often experience:

• Better heart efficiency – Improved blood flow and oxygen supply.

• Reduced symptoms – Less fatigue, swelling, and breathlessness.

• Lower risk of hospitalization – CRT can prevent complications related to heart failure.

Lifestyle Adjustments for Heart Health

To enhance the benefits of CRT, consider:

• Heart-Healthy Diet – Focus on low-sodium, nutrient-rich foods.

• Regular Exercise – Engage in doctor-approved physical activities.

• Stress Management – Practice relaxation techniques like meditation and deep breathing.

• Consistent Medical Follow-Ups – Stay proactive with regular health check-ups.
