Treating Severe Cardiac Issues through Implantable Devices

4 min read
severe cardiac issues

Cardiovascular disease can become life-threatening if symptoms persist after less intrusive therapies such as medication, lifestyle modifications, or minor surgery have been tried. When alternative therapies fail, implanted medical devices may be considered. Heart disease has been treated using implantable devices for decades. Over 40 years ago, the first pacemaker was implanted, and implantable defibrillators were first utilized in the early 1980s. However, in recent years, both the sorts of devices being tried for heart failure treatment and specialists’ optimism about their efficacy have increased. Long-term, the choices may be successful in treating some heart diseases. They can also serve as a bridge to more intrusive treatments like a heart transplant.

Different variety of cardiac devices 


The most well-known implantable medical device for cardiac patients is a pacemaker. It’s surgically implanted into the abdomen or chest cavities. They’re given to those who have arrhythmia, or an erratic heartbeat. This indicates that the heart is beating too quickly, too slowly, or unevenly.

Biventricular pacemakers:

A biventricular pacemaker functions similarly to a traditional pacemaker, except it sends electrical impulses to the heart through a third wire to resynchronize the contractions of the heart’s left lower chambers or ventricles.

Implantable cardioverter-defibrillator (ICD):

A small battery-powered device called an implantable cardioverter-defibrillator (ICD) is implanted in the chest to detect and stop abnormal heartbeats (arrhythmias). An ICD constantly monitors the heartbeat and, if necessary, administers electric shocks to re-establish a normal cardiac rhythm.

Cardiac loop recorders:

A loop recorder is a cordless cardiac monitor that constantly captures information about your heart’s rhythm for up to three years.

With advancements in technology, the choice of implantable cardiac pacing devices has grown. Pacemakers, implanted cardioverter defibrillators (ICDs), and cardiac resynchronization therapy devices (CRTs) have broadened their indications for the treatment, diagnosis, and monitoring of bradycardia, tachycardia, and heart failure. These devices are used to help persons with certain heart rhythm problems and heart failure control or detect irregular heartbeats. Because heart failure is not a distinct disease in and of itself, but rather a complication of other disorders, several treatment options have been devised. Some are derived from the well-known pacemaker, while others are from devices used as a stopgap before a heart transplant.

Are Implants Right for You?

Many people believe that the most significant barrier to the broad use of implants in heart failure treatment is their cost. Drug treatment is unquestionably less expensive, and most persons with heart failure are likely to be treated using drugs rather than devices in the short term. Many specialists have noticed that medical discoveries are always accompanied by cost issues. Currently, expenses are a significant hurdle, and much depends on the type of coverage provided by insurance providers. Experts are striving to develop better techniques of determining who will benefit the most from new technology when they are produced.

Before getting a heart implant, you should visit the proper doctor and get the entire knowledge about the procedure. To find the Best Cardiac Surgeons in India, visit the following site.

What makes pacemakers different from ICD?

A pacemaker sends electrical impulses to your heart to regulate its rhythm, but it can’t give you a shock to fix an arrhythmia. The majority of modern implantable cardioverter defibrillators (ICDs) can act as a pacemaker and detect hazardous heart rhythms. The ICD can give a shock to restore your heart’s regular rhythm if these are recognized.

Pacemakers and ICDs can survive anywhere from 5 to 7 years, relying on usage and device type. With an ICD, you can usually live a normal life. Find some of the Best Heart Surgery Hospitals in India

Precautions to be taken after getting a heart implant

  • Avoid equipment that uses magnetic resonance imaging (MRI) or other significant magnetic fields. These factors may have an impact on the pacemaker’s programming or performance. Additionally, the rapidly shifting magnetic field within the MRI scanner may cause the pacemaker leads to heat up. There are frequently better alternatives available with pacemakers than an MRI scan, but if your doctor deems that you need one, talk to your cardiologist first.
  • Avoid radio or television transmitters, arc welders, high-tension conductors, radar stations, and smelting furnaces, as well as other high-voltage or radar machinery.
  • Diathermy should be avoided at all costs. This is when heat is used to treat muscles in physical therapy.
  • The circuits in your gadget can be damaged by therapeutic radiation, such as those utilized in cancer treatments. Increased radiation doses increase the danger.
  • Without proper preparation, shock wave lithotripsy, which is used to remove kidney stones, may cause your equipment to malfunction. Before arranging any operation, make sure your doctor is informed of your pacemaker or ICD.

Success rate of heart implant surgery

Despite a rise in older and higher-risk heart transplant recipients, survival rates continue to improve. After one year, the rate of survival for adults is over 85 percent, and after five years, it is around 69 percent. The majority of heart transplant recipients have an excellent quality of life. You may be able to continue many of your daily routines, such as going back to work, engaging in hobbies and sports, and exercising, depending on your condition.

Heart transplantation has been used nearly completely on the basis of doctors’ judgment in a non-experimental clinical environment. Its effectiveness has not been examined in any prospective comparison research. As a result, almost all data used to guide prognosis comes from case reports and registries. The International Society for Heart and Lung Transplantation’s registry, which has collected data on over 60 000 heart transplants performed around the world over the last two decades, is the most comprehensive source of such information. Get to know more about the heart transplant dataset through the link provided below.
