Cardiac Intervention

Cardiac Resynchronization Therapy (CRT)

A specialised pacemaker-based therapy that resynchronises the heart's pumping chambers to improve function in patients with heart failure.

Overview

Understanding Cardiac Resynchronization Therapy (CRT)

What is Cardiac Resynchronization Therapy?

In some patients with heart failure, the electrical signal that triggers the heart's contraction becomes delayed or uncoordinated, causing the two lower pumping chambers (ventricles) to beat out of sync. This reduces the heart's overall pumping efficiency and worsens heart failure symptoms. Cardiac Resynchronization Therapy (CRT) uses a specialised pacemaker device with an additional lead placed to stimulate both ventricles simultaneously, restoring coordinated contraction and improving the heart's pumping efficiency.

Who Needs CRT?

Patients with moderate to severe heart failure symptoms despite optimal medical therapy
Patients with reduced ejection fraction and evidence of electrical dyssynchrony (wide QRS/left bundle branch block on ECG)
Patients who may also require defibrillator protection (CRT-D) alongside resynchronisation

How is CRT Implantation Performed?

The procedure is similar to standard pacemaker implantation, performed under local anaesthesia. In addition to leads placed in the right heart chambers, a specialised lead is guided through the coronary sinus vein to stimulate the left ventricle. All leads are connected to the CRT device, which is placed in a small pocket under the skin below the collarbone.

Benefits of CRT

Improves heart pumping efficiency by restoring coordinated ventricular contraction
Reduces heart failure symptoms such as breathlessness and fatigue
Lowers the risk of hospitalisation for worsening heart failure
Can be combined with defibrillator protection in appropriate patients

Recovery After CRT

Most patients are discharged within one to two days. Benefits often become apparent gradually over weeks to months, with device settings optimised at follow-up visits to maximise therapeutic effect.

Why Choose Dr. Prashant Dwivedi for CRT in Jaipur?

Dr. Prashant Dwivedi provides comprehensive heart failure device therapy, including careful patient selection and precise CRT implantation, to help eligible patients in Jaipur achieve meaningful symptom relief and improved quality of life.

Treatment suitability is confirmed only after clinical examination, cardiac imaging and detailed assessment by the specialist.

Treatment Journey

How the intervention is planned

Every procedure is planned according to the patient’s heart anatomy, symptoms and overall medical condition.

Detailed Evaluation

ECG and echocardiography confirm heart failure severity and electrical dyssynchrony.

Procedure Planning

CRT device type (with or without defibrillator) is selected based on individual risk.

Device Implantation

Leads, including one placed via the coronary sinus, are guided into the heart and connected to the CRT device.

Testing and Recovery

Device function is confirmed before discharge, usually within one to two days.

Optimisation and Follow-up

Device settings are fine-tuned at follow-up visits to maximise symptom improvement.

Frequently Asked Questions

Questions about Cardiac Resynchronization Therapy (CRT)

General information to help patients understand the intervention and treatment process.

Patients with moderate to severe heart failure, reduced ejection fraction and evidence of electrical dyssynchrony on ECG (such as left bundle branch block) tend to benefit most from CRT.

Unlike a standard pacemaker that paces one or two heart chambers mainly to prevent slow heart rates, CRT includes an additional lead to stimulate both ventricles together, specifically improving the heart's pumping coordination in heart failure.

Some patients notice improvement within weeks, while for others the full benefit develops gradually over a few months as the device settings are optimised and the heart's pumping pattern improves.

In many patients, CRT is combined with defibrillator protection (CRT-D) to both resynchronise the heart's contraction and guard against dangerous heart rhythms, based on individual risk assessment.
