Best Cardiac Resynchronization Therapy (CRT) for Heart
Cardiac Resynchronization Therapy (CRT), also known as biventricular pacing, is a medical treatment designed to improve the synchronization of the heart's chambers and enhance its pumping efficiency. CRT is primarily used to treat certain heart conditions, particularly heart failure patients with a specific type of electrical conduction abnormality known as left bundle branch block (LBBB).
Indications of Cardiac Resynchronization Therapy
CRT is indicated for individuals who have advanced heart failure and meet specific criteria, including:
- Reduced Ejection Fraction: Heart failure patients with a reduced ejection fraction (weakened pumping ability of the heart).
- Electrical Conduction Abnormalities: Individuals with heart failure and left bundle branch block (LBBB) who continue to experience symptoms despite optimal medical therapy.
Steps Involved in Cardiac Resynchronization Therapy
Cardiac Resynchronization Therapy (CRT) is a specialized treatment for heart failure and certain heart rhythm disorders. It involves the implantation of a device, often called a CRT pacemaker or CRT defibrillator, to improve the synchronization of the heart's chambers and enhance its pumping efficiency. Here are the general steps involved in a Cardiac Resynchronization Therapy procedure:
- Preoperative Evaluation: The patient undergoes a thorough medical evaluation, including reviewing medical history, medications, and heart function tests such as echocardiography and electrocardiography (ECG).
- Consent and Anesthesia:
- The patient meets with the healthcare provider to discuss the procedure, its risks, benefits, and alternatives. Informed consent is obtained.
- Anesthesia is administered to ensure the patient is comfortable and pain-free during the surgery. Local anesthesia with sedation or general anesthesia may be used.
- Implant Site Preparation: The implant site is typically on the chest, near the collarbone. The area is cleansed and sterilized to prevent infection.
- Incision and Pocket Creation: An incision is made near the collarbone, and a small pocket is created under the skin for the CRT device.
- Lead Placement: Leads (thin wires) are inserted through the incision and guided into the heart's chambers. These leads are positioned in the right atrium, right ventricle, and coronary sinus vein on the left side of the heart.
- Lead Connection to CRT Device: The leads are connected to the CRT device, which is placed in the pocket under the skin. The device monitors the heart's rhythm and delivers electrical impulses to synchronize the heart's contractions.
- Testing and Optimization: The healthcare team tests the CRT device's effectiveness by pacing the heart at different settings and assessing its response. They aim to achieve optimal synchronization of the heart's chambers.
- Closure and Dressing: The leads and device are secured in place, and the incision is closed with sutures or stitches. A sterile dressing is applied to protect the site and promote healing.
- Recovery and Observation: The patient is taken to a recovery area as they wake up from anesthesia. Vital signs are monitored, and any potential complications are addressed.
- Hospital Stay: CRT implantation is typically performed on an outpatient basis, allowing patients to return home the same day. In some cases, an overnight stay may be required for observation.
- Postoperative Care and Follow-Up:
- Patients receive instructions for recovery, including wound care, activity restrictions, and medication management.
- Follow-up appointments are scheduled to review device settings, assess heart function, and address any concerns.
Who will Treat for Cardiac Resynchronization Therapy
Cardiac Resynchronization Therapy (CRT) is typically performed by a specialized team of healthcare professionals, including cardiac electrophysiologists, interventional cardiologists, and cardiac surgeons.
- Cardiac Electrophysiologist: Cardiac electrophysiologists are specialized cardiologists who focus on diagnosing and treating heart rhythm disorders. They are the primary specialists involved in assessing whether a patient is a suitable candidate for CRT. They evaluate the patient's medical history, heart rhythm, and overall condition to determine if CRT is appropriate.
- Interventional Cardiologist: Interventional cardiologists are experts in performing minimally invasive procedures to treat heart conditions. They are responsible for implanting the leads and CRT device under the skin, usually below the collarbone. They ensure proper placement and synchronization of the device.
- Cardiac Surgeon (if necessary): In some cases, a cardiac surgeon might be involved, especially if additional procedures are required alongside CRT. For example, if there's a need for coronary artery bypass grafting (CABG) or heart valve repair/replacement, a cardiac surgeon might collaborate with the electrophysiologist and interventional cardiologist.
- Nursing Staff: Nurses play a critical role in pre-procedure preparation, patient monitoring, and post-procedure care. They assist the medical team and ensure that the patient's needs are met throughout the procedure.
- Anesthesiologist (if necessary): If sedation or anesthesia is required, an anesthesiologist will administer and monitor the sedation or anesthesia during the procedure.
- Imaging Specialists: Imaging specialists, such as echocardiographers and radiologic technologists, assist in guiding the leads and device placement using X-ray or other imaging technologies.
- Rehabilitation Team (post-procedure): After CRT, a rehabilitation team, including physical therapists and dietitians, may help with your recovery and provide guidance for resuming activities and adopting a heart-healthy lifestyle.
