Cardiac Resynchronization Therapy

What is Cardiac Resynchronization Therapy (CRT)?

Cardiac Resynchronization Therapy (CRT) is a specialized treatment designed to improve the heart's rhythm and overall efficiency. It involves the implantation of a small, pacemaker-like device that sends electrical impulses to both ventricles (the heart's lower chambers), helping them contract in a more synchronized manner. This therapy is particularly beneficial for individuals experiencing heart failure due to delayed electrical conduction within the heart.

Who is Cardiac Resynchronization Therapy For?

CRT is commonly recommended for patients who suffer from moderate to severe heart failure and exhibit symptoms such as shortness of breath, fatigue, and reduced physical endurance. Additionally, patients with an electrical disorder known as left bundle branch block (LBBB) often benefit from this treatment. CRT is also an option for those who have not responded adequately to standard heart failure medications.

How Does CRT Work?

The CRT device, once implanted under the skin near the collarbone, sends carefully timed electrical signals to the heart to restore coordination between the ventricles. The device has leads (thin insulated wires) that are placed in different areas of the heart to help synchronize contractions, improving the heart's pumping ability. This enhancement in function can lead to better blood circulation and a significant reduction in heart failure symptoms.

Benefits of CRT

CRT has been shown to improve the quality of life for heart failure patients by alleviating symptoms, increasing exercise capacity, and reducing hospitalizations. Many patients experience a decrease in fluid buildup, which can further relieve swelling and improve breathing. In some cases, CRT may even enhance overall survival rates for patients with chronic heart failure.

Is CRT Safe?

Cardiac Resynchronization Therapy is considered a safe and effective procedure for most eligible patients. Like any surgical intervention, there are potential risks, such as infection at the implantation site or lead-related complications. However, advancements in medical technology have significantly improved the success rate and safety of CRT procedures. After the procedure, patients will undergo follow-up appointments to monitor their device and overall heart health.
