Cardiac resynchronization therapy (CRT) is a specialized treatment designed to improve the heart's efficiency in patients suffering from heart failure, particularly those with abnormal electrical conduction. Heart failure affects millions of people globally, and many struggle with symptoms that reduce their quality of life. CRT is a life-changing intervention that addresses these issues and helps patients regain control over their heart function.
In this blog, we will delve into the meaning of CRT, its importance, the procedure itself, precautions to take before and after the therapy, and the role of providers like TheHeart.ae in ensuring successful outcomes.
Understanding Cardiac Resynchronization Therapy (CRT)
CRT is a treatment aimed at coordinating the contractions of the heart’s chambers—specifically, the left and right ventricles. For patients with heart failure, the two ventricles often fail to pump in sync, leading to inefficient blood flow and worsening heart function.
Heart failure often occurs when the electrical impulses that regulate heartbeat are irregular. These electrical issues lead to dyssynchrony between the heart's ventricles, meaning they are no longer working in harmony. This not only weakens the heart's ability to pump blood but also exacerbates symptoms such as fatigue, shortness of breath, and fluid retention.
CRT involves implanting a small pacemaker-like device near the heart to help resynchronize the ventricles. The device sends electrical impulses to the ventricles, prompting them to beat in a more coordinated and efficient manner, improving blood flow and overall heart function.
Why is CRT Important?
1. Improving Heart Efficiency: Heart failure patients with electrical conduction disorders often experience severe symptoms due to poor heart efficiency. CRT ensures the ventricles work in sync, significantly improving the heart's ability to pump blood throughout the body.
2. Enhanced Quality of Life: Many heart failure patients experience a noticeable improvement in symptoms after CRT. The treatment reduces breathlessness, increases exercise capacity, and improves energy levels. As a result, patients can resume many of their daily activities, improving their overall quality of life.
3. Reduced Hospitalizations: CRT has been shown to reduce hospital admissions due to heart failure-related complications. By improving heart function, it stabilizes the patient’s condition and reduces the risk of emergencies and severe health declines.
4. Longevity: Studies have indicated that CRT can reduce mortality rates in certain heart failure patients. By improving heart function and reducing complications, CRT can extend patients' lifespans and enhance their long-term prognosis.
How is CRT Performed?
The Procedure:
CRT is a minimally invasive procedure performed under local anesthesia and mild sedation. Here’s an overview of the steps involved:
1. Preparing for the Procedure: Before the procedure begins, the patient will receive local anesthesia to numb the area. The physician will also administer a mild sedative to keep the patient relaxed but awake.
2. Implanting the Device: The doctor makes a small incision, typically near the shoulder, and inserts leads (thin, insulated wires) into the heart’s ventricles through the veins. These leads are carefully positioned to ensure they reach the appropriate areas of the heart.
3. Attaching the CRT Device: Once the leads are properly placed, they are connected to the CRT device, which is implanted under the skin near the collarbone. The device is programmed to send electrical impulses to the heart, helping synchronize the contractions of the ventricles.
4. Testing and Fine-Tuning: After implantation, the doctor tests the device to ensure it’s working properly. Adjustments are made as necessary to ensure the heart responds correctly to the electrical impulses.
5. Post-Procedure Care: The incision is closed, and the patient is monitored for a few hours to ensure no immediate complications arise. Most patients are able to return home the same day or the day after the procedure.
Precautions Before and After CRT
While CRT is a relatively low-risk procedure, there are important precautions that patients should follow both before and after the treatment to ensure the best outcomes:
Before CRT:
1. Medical History: Inform your healthcare provider of your full medical history, including any allergies, past surgeries, or ongoing conditions, to ensure the CRT procedure is safe for you.
2. Medication Management: Patients may need to adjust their medications leading up to the procedure, particularly blood thinners, as these can increase the risk of bleeding during surgery. Your doctor will provide specific instructions on how to manage your medications in the days leading up to CRT.
3. Pre-procedure Testing: Patients will likely undergo a series of diagnostic tests, including electrocardiograms (ECGs), echocardiograms, and blood tests, to evaluate the heart's condition before the procedure. These tests are crucial for identifying the optimal settings for the CRT device.
After CRT:
1. Wound Care: After the procedure, patients must keep the incision site clean and dry to prevent infection. It’s also important to avoid heavy lifting or strenuous activities for a few weeks to allow the area to heal properly.
2. Device Monitoring: After implantation, the CRT device will need to be periodically monitored and adjusted. Follow-up appointments with your cardiologist are critical to ensure the device is functioning correctly.
3. Symptom Monitoring: If any unusual symptoms occur, such as dizziness, fainting, or chest pain, patients should seek medical attention immediately. These could indicate that the device is not functioning as intended or that the heart condition has worsened.
4. Lifestyle Adjustments: While CRT can significantly improve heart function, patients must still follow a heart-healthy lifestyle. This includes regular exercise (as advised by a healthcare professional), a balanced diet low in sodium and fats, and avoiding smoking and excessive alcohol consumption.
