Heart synchronization treatment (CRT): Procedure details and healing process

Heart synchronization treatment (CRT): Procedure details and healing process

Cardiac Resynchronization Therapy (CRT), a well-established treatment for eligible patients with heart failure, has been shown to provide significant long-term benefits while carrying certain risks. This advanced therapy, which involves the placement of a specialized device called a biventricular pacemaker or cardiac resynchronization therapy device, aims to synchronize the contractions of the heart's chambers, particularly when there is delayed or abnormal electrical conduction.

The main goals of CRT are to alleviate the symptoms of heart failure, improve cardiac synchronization, enhance quality of life, and improve sleep quality. Before undergoing CRT, individuals undergo various tests such as an electrocardiogram (ECG), echocardiogram, and possibly a cardiac catheterization.

CRT offers durable improvements in cardiac function, symptom relief, and survival for carefully selected heart failure patients. Studies show that patients with stable or improved echocardiographic parameters after CRT have significantly better long-term survival than those with disease progression. CRT reduces hospitalization rates and the risk of death in patients with moderate to severe heart failure who meet criteria such as a reduced ejection fraction and wide QRS complex.

Many patients experience more energy, improved exercise capacity, less shortness of breath, and better mood following CRT implantation. CRT combined with a defibrillator (CRT-D) significantly lowers the incidence of ventricular arrhythmias in heart failure patients with left bundle branch block, reducing sudden cardiac death risk. Exercise programs post-CRT can further enhance ejection fraction, functional capacity, and quality of life.

However, CRT is not without risks. The procedure, which takes 2-5 hours and can be performed using either the endocardial or epicardial technique, carries procedural risks such as infection, lead displacement, pneumothorax, or bleeding. Over time, device malfunction, lead failure, infections, or the need for battery replacement may occur.

CRT is not suitable for all heart failure patients. Optimal benefits are observed in those with specific electrical conduction abnormalities like left bundle branch block and reduced ejection fraction. Patients with significant comorbidities may not derive the same benefit. Not all patients respond equally; while some have marked improvement ("super-responders"), others may be "nonprogressors" with stable disease or "progressors" with worsening heart function, requiring closer monitoring and possible therapy optimization.

In the United States, Medicare and Medicaid cover the cost of CRT, but health insurance plans may require pre-authorization or documentation of medical necessity. The total cost of CRT in an ambulatory surgical center is $8,236, with a patient paying $1,646. In a hospital outpatient department, the cost is $10,840, with a patient paying $1,702. Recovering from CRT may involve follow-up care, medications, device checks, and a recovery timeline that varies depending on individual factors.

After the procedure, individuals are typically kept in the hospital for 24 hours to 5 days for monitoring. CRT can significantly improve the ability to perform daily activities, reduce the need for hospitalizations, and allow individuals to engage in physical activities with less discomfort and improve their exercise tolerance. In some cases, CRT may improve survival rates in certain individuals with severe heart failure symptoms and reduced heart function.

Medical advancements are improving the outcomes of CRT procedures, and with careful patient selection, ongoing clinical follow-up, and optimization, CRT can provide a beacon of hope for those battling heart failure.
