  • Cardiac Arrhythmias
  • Coronary Artery Disease
  • Atherosclerosis
  • Tachycardia
  • Blocked Arteries
  • Bradycardia
  • Angina

A healthy and long life for a person with structural heart conditions can not happen without interventional procedures. Patients with these heart conditions can be provided with best treatment with the assistance of modern technology and world class equipments. It is essential that when procedures are performed on patients with these conditions, they are followed up with best of post procedural care.

Signs to look for before visiting Dr Pradeep Nayak

We bring to you the various symptoms and signs in patients having structural or non-coronary cardiovascular conditions:

  • Dizziness
  • Chest Pain
  • High Blood Pressure
  • Palpitations
  • Shortness of breathe

Few commonly experienced symptoms are chest pain and fatigue in patients with these heart conditions. A structural heart issue can lead to high blood pressure for prolonged periods of time. Kidneys start getting affected because of structural heart issues and kidney dysfunction could also happen.

Operating Hours of Dr Pradeep Nayak

The doctor's operating hours are 6 days a week, 10 am to 7 pm. It speaks to the efficiency and skill of the interventional cardiologist that less time is taken to complete procedures.

Popular Prcedures Performed by Dr Pradeep Nayak

Dr. Pradeep Nayak performs numerous popular interventional cardiology procedures as mentioned here::

  • Angiography (Including Non-Ionic Contrast)
  • Pacemaker Implantation Surgery
  • Angioplasty
  • EPS & RFA

To open blocked arteries, interventional cardiologists commonly perform procedures such as stent placement, angioplasty and atherectomy. The procedure to insert defibrillators and pacemakers to correct abnormal heart rhythms is also regularly performed.

Angiography (Including Non-Ionic Contrast)

Most physicians advise their patients to undergo the angiogram procedure (also known as angiography and arteriogram) when certain symptoms such as a heart attack or chest pain become a source of worry. A stress test is performed on patients who report chest pain, which is then followed by an angiogram test.

Angiography procedure aims at testing the blockages in the coronary arteries apart from any other cardiovascular-related ailments. Angiography and angiogram procedure can both locate narrowing arteries or blockages that may exist in different parts of the body.

Angiography is recommended for patients with coronary heart diseases (CHD), which can cause the heartbeat to stop suddenly and abruptly. The patient may also suffer from severe chest pain. Angiography can also be performed on patients on an emergency basis when they experience a heart attack. If the blockage is not treated immediately, then healthy tissues around the heart start perishing and turn into scar tissue. It can give rise to several long-lasting problems. Angiography may also be required in the case of a patient with aortic stenosis or those who have had an abnormal heart stress test.


Coronary artery disease (CAD) is one of the most common heart diseases reported across the world. It results due to blood clot formation and plaque accumulation in the major blood vessels of the heart.

Balloon angioplasty is the most common endovascular procedure (procedure performed inside the blood vessel) carried out to treat coronary artery disease. In this procedure, the blood clots in the major arteries of the heart are detected and cleared by inserting a catheter into an artery of the hand (radial artery) or leg (femoral artery). This catheter consists of a balloon at its tip, which dislodges the clot to the periphery of the blood vessel after inflation.

Angioplasty may or may not be followed by coronary stent placement, depending on the angiography findings. This procedure is performed in patients with fewer blood clots in the vessels and those who do not respond to medications. It may also be carried out as an emergency procedure to treat a heart attack.

Signs and symptoms of plaque deposits in the heart

  • Fatigue and dizziness due to insufficient blood supply to the tissues and overall decreased efficacy of the heart
  • Shortness of breath to compensate for inadequate pumping of the blood
  • Compromised blood flow to the heart resulting in heart attack, characterized by pain in the chest, lower jaw, and left arm

Radiofrequency ablation (RFA) is a surgical procedure in which heat generated from medium frequency alternating current is used to ablate a tumour, a part of the electrical conduction system of the heart, or any other dysfunctional areas. The ablation therapy requires local anaesthesia and is done in an outpatient setting.

RFA is a popular treatment for the correction of any abnormality in the electrical system of the heart, which is confirmed during electrophysiology studies (EPS). During this test, the electrophysiology of heart is studied and any abnormalities are noted. The procedure used to correct the identified abnormalities associated with electrophysiology of heart is known as the cardiac ablation procedure.

Pacemaker Implantation Surgery

How does a Pacemaker Implant work?

Pacemaker implantation is a common surgery and it significantly improves the quality of life led by the patient.  The blood-pumping organ, heart, is essentially made of a few groups of muscles. These muscles are controlled by electrical signals to ensure that the heart beats naturally and effectively to circulate blood to all parts of the body. When this electrical signal gets disrupted due to some reason, then an individual may experience tachycardia (where hear beats abnormally slow), heart block, arrhythmia (irregular heartbeat), or a cardiac arrest (abrupt and sudden stopping of the heartbeat).

The contractions happen as a result of triggered electrical pulses generated by sinoatrial node or the SA node. It acts like a pacemaker of the heart. This electrical pulse is then sent to the atrioventricular node or the AV node for relaying the pulse to the ventricles. Pacemaker implantation is suggested when this electrical signaling network is disrupted.The faulty functioning of the natural pacemaker of the heart may lead to the following:

Sick sinus syndrome: It is characterized by a slow heartbeat (bradycardia) or fast heartbeat (tachycardia) or a combination of both. It can happen due to age, a previous history heart attack, and thyroid problem, too much of potassium accumulation in blood, heart surgery, or sleep apnea.

Heart Block

In this case, the impulse is either delayed or absent.

Cardiac arrest

The heart can stop beating. It may result because of the presence of coronary artery disease and muscle problems in the heart, which can happen after the age of 35.


Some of the symptoms observed in patients requiring pacemaker implantation are:

  • Bradycardia
  • Tachycardia
  • Uncontrollable fatigue
  • Dizziness experienced throughout the day
  • Shortness of breath
  • Acute chest pain
  • Palpitation and fluttering of the heart (arrhythmia)

What is a pacemaker implant?

A pacemaker implant is a small device that weighs around 20 g to 50 g and is the size of a matchbox. It has a pulse generator with a battery, a tiny computer circuit and a few wires called pacing leads. This system is attached to the heart and it emits signals through the wires. The pacing rate or the rate of electrical impulses can be adjusted as per the requirement of the body and be accordingly programmed. It can sense if a heartbeat is missed or if the heart is beating too slow. Accordingly, it starts sending a steady signal to normalize the beating of the heart. If the beats are normal, then it simply does not send any signal.

  • Myocardial Perfusion Imaging (MPI)
  • Exercise Stress
  • Cardiac Computed Tomography

The tests tie in with the treatment plan which can be decided upon basis your discussion with the doctor. The health of blood vessels and the heart or any structural defect becomes clear post the results.

When should you go to see a Interventional Cardiologist?

A balanced lifestyle including a healthy diet, exercise, not smoking or drinking helps in keeping your heart healthy. Cardiovascular issues or structural defects in your heart can be treated with interventional cardiology techniques. Interventional cardiologists treat heart conditions with catheter-based treatments which are non surgical. This specialty of doctor can also be consulted if your visit to a cardiologist does give you the solution and additional work needs to be done.
