CRTD Implant Procedure in Hyderabad

When heart problems affect you, you need care in terms of healthy habits and a medical helpline. The CRTD Implant procedure or cardiac resynchronization therapy device is a great help to save the lives of people by monitoring the heart rhythm, identifying irregularities, and use subtle electric simulations to make corrections.

When your heart shows serious issues like heart failure, Dr. Asif, who is a Best Cardiologist in Hyderabad with over 14 years of experience has expertise in cardiac resynchronization therapy device CRTD Implant procedure and has an excellent track of service in treating critical patients successfully. Dr. Asif ensures to treat his patients with compassion , care and promises a smooth ride throughout the procedure.

What is Cardiac resynchronization therapy (CRT)?

Sometimes the heart does not pump well, the heart beats out of sync. This can be caused by heart disease, ageing, genetics, certain medications, and other factors. CRT assists the heart in pumping normally by assisting the right and left ventricles of the heart in pumping together. To accomplish this, special wires are implanted in the heart to pace the heart muscle in a way that improves pumping function.

What is a CRT-D device?

This device is made up of two parts: the pulse generator (device) and the insulated wires (leads). Through these insulated wires, a cardiac resynchronization therapy defibrillator device delivers small electrical currents to the heart. This device aids in the restoration of normal heartbeats by allowing both ventricles to pump more efficiently together.

How CRT-D Devices Work?

A Cardiac Resynchronization Therapy Defibrillator or CRT-D is a cardiac device that sends electrical impulses through insulated wires placed in the heart to coordinate the contractions of the upper and lower chambers of the heart. In addition, both ventricles are paced to improve heart pumping. A CRT-D can also be used to treat life-threatening rhythms. A CRT-D, unlike a traditional pacemaker, has an extra lead on the left ventricle to help the heart pump more coordinated way.

CRTD Implant procedure in Hyderabad is a treatment for the symptoms and complications of heart failure (HF). HF is a common condition in which the heart's pumping action is impaired due to improper heart contraction. CRT-D treatment by Cardiologist in Hyderabad involves implanting a device in your chest that helps to regulate your heartbeats and monitors your heart's condition, allowing your Top Heart Specialist in Hyderabad to prescribe the best treatment for you. A CRT system is made up of two parts.

  • • The heart device, which is actually a small computer with a battery, is contained in a small titanium metal case the size of a pocket watch.
  • • Insulated wires known as leads are implanted to carry information signals from your heart to the heart device as well as electrical impulses to your heart.

Who needs a CRT-D?

With a CRT-D, many patients' quality of life improves significantly. A cardiologist performs an interventional procedure to implant a CRT-D.

The patient may need the device if:

  • CHF (Congestive Heart Failure)
  • • The patient has a history of, or is at risk of, Ventricular Tachycardia (VT) or Ventricular Fibrillation (VF), both of which cause the heart to beat too quickly.
  • • Cardiomyopathy (weakened and enlarged heart muscle)
  • • There is a significant electrical delay between the lower pumping chambers (bundle branch block)

Causes for Heart Failure:

  • • A prior heart attack
  • • Coronary artery disease (clogged blood vessels)
  • • High blood pressure
  • • A virus
  • • An arrhythmia (irregular heart rhythm)
  • • Diabetes
  • • Diseases of the heart muscle or valves

Symptoms of Heart Failure:

There may not be any symptoms during the early stages. However, as the heart disease progresses, one or more of the following symptoms may begin to appear:

  • • Shortness of breath (dyspnoea)
  • • Fatigue
  • • Chronic coughing or wheezing – Fluid congestion in the lungs is common with heart failure
  • • Fluid retention or swelling
  • • Rapid or irregular heartbeat
  • • Confusion – Confusion, impaired thinking or mental sluggishness due to reduced blood flow to the brain

Diagnosis for CRTD Implantation:

Before the cardiologist decides whether the patient requires CRTD Implant Procedure in Hyderabad, several investigative procedures must be performed to determine the cause of the arrhythmia. These may include:

  • • Electrocardiogram (ECG)
  • • Holter monitoring
  • • Echocardiogram
  • • Stress test

How is CRT-D Implantation Procedure Performed?

  • • A small incision, approximately 2 inches, will be made in the upper chest.
  • • Three leads (thin insulated wires) will be guided through a vein and into the heart.
  • • The doctor will connect the leads to the implanted heart device, test the device, and program the settings.
  • • The device will be inserted beneath the skin and the chest incision will be closed by our Best Cardiologist in Hyderabad.

What happens after the CRT-D Implantation?

After the device is implanted, you will be hospitalised for a day or two. After you leave the hospital, the doctor will give you instructions on how to care for your incision. For a short period of time after the surgery, your arm's range of motion may be limited after surgery until the wound heals completely. Because of the CRT-D, a small bulge is visible underneath the skin in some cases.

How is recovery after CRT-D procedure?

Full recovery can take several days to months. It is best to avoid strenuous activities that put excessive stress on your upper body during this time, such as lifting heavy weights. It is also critical to avoid rough contact because it may cause your implant site to be damaged. Most patients in our MEDS Super speciality hospital, The Best Heart Hospital in Hyderabad can return to normal activities within 2-4 weeks.

What are the advantages of using a CRT-D device?

CRT-D can be a life-saving therapy for patients with heart failure who are at a higher risk of dying from a sudden cardiac arrest. The device detects dangerously rapid heart rhythms, which can result in death in a matter of minutes, and delivers a shock to stop the abnormal rhythm. Chronic heart failure patients benefit from CRT devices that improve their quality of life and shorten their hospital stay. Patients who use CRT devices report significant relief from symptoms such as shortness of breath and fatigue, and feel more energetic.


Some of the risks CRT-D implantation may include,

  • • Bleeding
  • • Formation of a blood clot
  • • Damage to adjacent structures (tendons, muscles, nerves)
  • • Puncture of a lung or vein
  • • Damage to the heart tissue
  • • Arrhythmias
  • • Heart attack
  • • Stroke

Can I have an MRI if I have a CRT-D device implanted?

Yes. There are now MRI-compatible CRT-D devices available that allow the patient to undergo an MRI scan safely. Earlier, ICD implants could have been damaged by magnets used in Magnetic Resonance Imaging (MRI).

Can I use a mobile phone if I have an CRT-D?

If you follow these steps, you can use a mobile phone:
Hold the phone to your ear on the opposite side of your body from your ICD. Keep your phone at least six inches away from the device when it is turned on. For example, don’t carry your phone in your chest pocket over your device.

Does getting A CRTD Require Surgery?

Yes, the CRT-D is implanted under the skin, and one or more wires (referred to as "leads") are inserted into the heart. The procedure takes a few hours. You may be admitted to the hospital for the night.
