Intracardiac Devices Implantation

CTD, commonly referred to as CRT-D (Cardiac Resynchronization Therapy with Defibrillator), is an advanced cardiac device that combines the functions of a pacemaker and an ICD. It is specially designed for patients with advanced heart failure and poor heart pumping function. CRT-D helps coordinate the contractions of the heart’s ventricles while also protecting against life-threatening arrhythmias.

This therapy improves heart efficiency, reduces heart failure symptoms, lowers hospitalization rates, and significantly enhances quality of life. CRT-D is particularly beneficial in patients whose heart chambers do not beat in a synchronized manner.

Why Is CRT-D Needed?

• Advanced heart failure

• Poor left ventricular function

• Electrical dyssynchrony of the heart

• High risk of sudden cardiac death

• Symptoms despite optimal medications

Procedure

CRT-D implantation is performed under local anesthesia or mild sedation. Multiple leads are placed in different chambers of the heart to synchronize heartbeats. The device is implanted under the skin, usually below the collarbone. The procedure may take slightly longer than standard pacemaker implantation. Patients are monitored closely post-procedure and usually discharged within a few days.

FAQs

Q1. How is CRT-D different from a pacemaker?
It improves heart pumping and prevents dangerous arrhythmias.

Q2. Can CRT-D improve heart failure symptoms?
Yes, it significantly improves symptoms and quality of life.

Q3. Is CRT-D safe?
Yes, when implanted by an experienced cardiologist.

Q4. Will I need lifelong follow-up?
Yes, regular device check-ups are essential.
