Intervention Cardiology

Interventional cardiology conducted at the advanced cardiac catheterization laboratory includes:

  • Coronary angiography
  • Radial angiography
  • Coronary angioplasty or primary angioplasty
  • Valvuloplasty
  • Peripheral angioplasty
  • Permanent pacing
  • ICD implantation
  • Rotablation

Two cardiac catheterisation laboratories handle an array of diagnostic and therapeutic procedures. A skilled team of cardiologists and technicians have ensured that the success rate is on par with international standards and the mortality rate is as low as 0.0001%. To date, BMBHRC has performed over 19,000 cardiac interventions.

Least Invasive Angiography (Radial)

Earlier, coronary intervention hadto be performed via the femoral artery. Following this procedure, the patient needed to lie flat, without bending their leg for 2 to 6 hours, or sometimes longer, to allow the artery to heal. In some cases, even if immobile, severe internal bleeding could occur requiring blood transfusions or surgery to repair the femoral artery. Today though, these procedures are being performed via the radial artery. Most patients find radial catheterisation comfortable compared to femoral catheterization, as it allows patients to immediately to sit up, walk and eat normally. Radial catheterisation also reduces bleeding complications, and allows the patients go home the same day.


Coronary Angiography, also know as a Coronary Arteriography or Coronary Angiogram, is a test that produces pictures of the blood vessels and chambers of the heart through X-rays. A Coronary Angiogram tells Cardiologists how well the chambers of your heart and your heart valves are working. This test can also provide other essential information, like the blood pressure inside your heart. Coronary arteries are those blood vessels that carry blood from your heart to the rest of your body. The blood then returns to the heart through veins. A Coronary Angiogram can also show narrow or blocked blood vessels that surround the heart. If blockages are detected, the patient may need further treatment.


There is a constant supply of blood to the heart through two large blood vessels called the left and right coronary arteries. When these arteries are blocked or have narrowed down, a surgical procedure called Coronary Angioplasty is performed. Hardening of these coronary arteries can result in Angina, a syndrome that is caused due to less supply or oxygen or rich blood to the heart. While many cases of angina can be treated with medication, severe cases may require a Coronary Angioplasty to restore the blood supply to the heart. Coronary Angioplasties are also used as a treatment following a heart attack, and are one of the most common and non-invasive types of heart surgery.

Other Procedures (Pacemaker, Valvuloplasty, EP Study)

A pacemaker is a small device that is placed in the chest wall, just below the collarbone, to help control abnormal heart rhythms. A pacemaker gives electrical pulses to stimulate the heart and help it beat at a normal rate. It is used to treat slow heart rate.

Biventricular Pacemaker or Cardiac Resynchronisation Therapy (CRT) is a treatment for patients with severe heart failures. These patients generally have an abnormal electrical system of the heart. This treatment can restore the coordinated contraction of the left ventricle and improve the functioning of the heart. Scientific evidence has shown that CRT implantation reduces the number of heart failures.

An Implantable Cardioverter Defibrillator (ICD) is a small battery-powered electrical pulse generator that is approximately twice the size of a pacemaker, but is implanted the same way. An ICD is implanted in patients who have the risk of sudden cardiac death due to abnormally fast heart rates (ventricularfibrillation and ventricular tachycardia). The device is programmed to detect abnormal heart rhythms and correct it by delivering an electrical shock to the heart.

EP Study
An Electrophysiology study (EP study) is performed in a cardiac catheterisation laboratory with the help of a technology known as the EP system. An EP study and the procedure of ablation are done to analyse and monitor heart activity. This study is done to patients with a heart rate much below normal, resulting in dizziness, blackouts and an underlying rhythm disorder.
