What is CRT-D Implantation?
CRT-D (Cardiac Resynchronization Therapy with Defibrillator) is a specialized implantable cardiac device used to treat patients with heart failure and abnormal electrical conduction, particularly those with ventricular dyssynchrony such as Left Bundle Branch Block (LBBB).
The device performs two important functions: Cardiac Resynchronization Therapy (CRT), which synchronizes the contraction of both ventricles to improve the heart's pumping efficiency, and Implantable Cardioverter Defibrillator (ICD), which detects dangerous ventricular arrhythmias and delivers pacing or electrical shocks when needed to prevent sudden cardiac death.
India has become one of the preferred destinations for CRT-D implantation due to its experienced cardiac electrophysiologists, advanced electrophysiology (EP) laboratories, internationally accredited hospitals, high procedural success rates, and affordable treatment costs.
Who Needs CRT-D Implantation?
Your orthopedic surgeon may recommend this procedure if you have:
- Heart Failure with Reduced Ejection Fraction (HFrEF)
- Left Ventricular Ejection Fraction (LVEF) ≤35%
- Left Bundle Branch Block (LBBB)
- Wide QRS Complex (typically ≥130–150 ms)
- Dilated Cardiomyopathy
- Ischemic Cardiomyopathy
- Non-Ischemic Cardiomyopathy
- NYHA Class II, III, or selected Class IV heart failure despite optimal medical therapy
- High risk of sudden cardiac death
- Previous ventricular tachycardia or ventricular fibrillation

Types of CRT-D Implantation
CRT-D (Cardiac Resynchronization Therapy with Defibrillator)
Provides synchronized ventricular pacing and protects against sudden cardiac death by delivering anti-tachycardia pacing or defibrillation shocks when required.
CRT-P (Cardiac Resynchronization Therapy Pacemaker)
Provides synchronized pacing but does not include a defibrillator.
Upgrade to CRT-D
Some patients with an existing pacemaker or ICD may require an upgrade to CRT-D if heart failure progresses or new conduction abnormalities develop.
Benefits
- Improves heart pumping efficiency
- Synchronizes ventricular contractions
- Reduces heart failure symptoms
- Lowers the risk of sudden cardiac death
- Decreases hospital admissions
- Improves exercise tolerance
- Enhances quality of life
- Continuously monitors heart rhythm
- Delivers life-saving therapy during dangerous arrhythmias
The Procedure
- Pre-procedure evaluation and device planning
- Administration of local anesthesia with conscious sedation
- Small incision below the collarbone
- Insertion of pacing and defibrillator leads through a vein
- Placement of leads in the right atrium, right ventricle, and coronary sinus for left ventricular pacing
- Connection of the leads to the CRT-D generator
- Device testing and programming
- Closure of the incision
- Observation and recovery
Duration: The surgery usually takes 2–4 hours, depending on the patient's anatomy and procedural complexity.
Recovery Timeline
Success Rate
CRT-D implantation is a well-established therapy that improves symptoms, reduces heart failure hospitalizations, and lowers the risk of sudden cardiac death in appropriately selected patients, with overall outcomes depending on patient selection, heart failure severity, left ventricular function, presence of LBBB, underlying heart disease, the electrophysiologist's expertise, and device optimization after implantation; many appropriately selected patients experience significant improvement in heart function and quality of life following CRT-D implantation.
Risks
Although crt-d implantation is generally safe, possible risks include:

Frequently Asked Questions
CRT-D is a cardiac device that combines cardiac resynchronization therapy (CRT) with an implantable cardioverter-defibrillator (ICD) to improve heart function and prevent sudden cardiac death.
Patients with symptomatic heart failure, reduced ejection fraction, electrical conduction abnormalities such as LBBB, and an increased risk of ventricular arrhythmias may benefit from CRT-D.
A standard pacemaker treats slow heart rhythms, while CRT-D synchronizes both ventricles and can also detect and treat life-threatening fast heart rhythms by delivering pacing or a shock.
The procedure usually takes 2–4 hours, depending on the patient's anatomy and procedural complexity.
No. It is a minimally invasive procedure performed through a small incision under local anesthesia with sedation.
Most patients stay in the hospital for 1–3 days.
International patients are generally advised to remain in India for 7–10 days after implantation for device programming and follow-up.
Most CRT-D batteries last approximately 5–10 years, depending on device usage, pacing requirements, and delivered therapies.
Yes. Most patients experience improved symptoms and quality of life. Regular follow-up and device checks are important, and your cardiologist will advise you about physical activity and lifestyle.
Medicare Spots assists international patients with expert electrophysiology opinions, hospital and specialist selection, treatment planning, medical visa support, travel arrangements, accommodation, dedicated patient coordination, and post-treatment follow-up to ensure a smooth treatment journey in India.
