Invasive & Non-Invasive Cardiology

INVASIVE CARDIOLOGY

Coronary Angiography:

Coronary Angiography is a diagnostic procedure which is done to detect blockage in the vessels supplying the heart. It is a procedure done under light sedation. Angiography can be done through the arm vessel (Radial) or leg (Femoral).
The procedure is indicated in patients who have Angina (chest pain) to direct further therapy which may be medical treatment, angioplasty or bypass surgery.

Percutaneous Transluminal Coronary Angioplasty (PTCA)

PTCA is a Cardiovascular interventional procedure where blocked vessels of the heart are opened by minimal access invasive technique. The blood vessels of the heart are usually accessed through an arm vessel (Radial route) or leg vessel (femoral route) and a guide wire is passed through the blockage and the narrowed segment is dilated with a balloon which is passed over the wire. This can be done in an emergency when a patient comes in with a heart attack (Primary Angioplasty) or as an elective case in a stable patient. Following angioplasty usually a medicated (drug eluting) stent or a drug eluting balloon is implanted in the vessel. Thereafter, patient is observed in the hospital for a day or two and discharged.

Balloon Mitral Valvuloplasty (BMV)

This is a Cardiac Interventional procedure in which the left sided valve (mitral valve) is dilated by means of a balloon which releases the obstruction of the valve (mitral valve). This mitral valve obstruction is usually seen in Rheumatic heart disease which is fairly common in India and mitral stenosis is its common sequelae. This procedure is carried under light sedation and a balloon to passed over the wire through the groin to the left side and the mitral valve is dilated. Similarly, other valves of the heart such an aortic and pulmonary valve can also be opened by means of a minimal access procedure which are known as Aortic Valvuloplasty and Pulmonary Valvuloplasty respectively. The procedure is done under light sedation.

Peripheral Angioplasty

Obstruction of the blood vessel of the thighs, legs, or arms can cause pain while walking (claudication) or during exertion and can also cause gangrene of the limbs. Intervention can open leg or arm vessels with balloons and  stents. The procedure is simple and easily amenable to intervention.

Carotid Angioplasty

Obstruction of the blood vessels of the neck can give rise to stroke. This obstruction, commonly encountered is the carotid artery stenosis which is usually relieved by wire, balloon and stent.  However such opening can lead to stroke due to embolisation of plaque in the brain during procedure. Therefore,  a filter  device  ( umbrella device) is used to trap the plaque and is necessary during carotid stenting.

NON-INVASIVE CARDIOLOGY

ECHOCARDIOGRAM

Echocardiograpy is the most frequently used initial cardiac imaging test to evaluate all cardiovascular diseases related to a structural, functional or haemodynamic abnormality of heart or great vessels.

It is used for diagnosis of valve related congenital and acquired disease of heart.

In special cases, trans-esophageal Echo is also done where in an endoscope like instrument is passed in the food pipe (through the mouth) to evaluate the structure of heart.

TMT

The Treadmill Test (TMT) is an exercise test which is designed to put gradually increasing stress on the heart and circulatory system to evaluate the response of heart to stress. This helps in determining the functional capacity of the heart and aids in diagnosis of coronary artery disease. 

A number of times rhythm disorder of heart can also be evaluated by treadmill test.

STRESS TEST

Two types of Stress Testing :

  • Exercise using Treadmill
  • Pharmacological (by giving I/V medication)

 Exercise Stress Testing

Exercise Electrocardiography is one of the most frequent non-invasive modalities used to assess patients with suspected or proven coronary artery disease.

Echocardiogram is done before exercise (at rest) and after exercise to see the effects of stress on heart.

Pharmacological Stress Test

In this dobutamine is given in the form of infusion in incremental doses, at regular intervals as mentioned in the protocol till the target heart rate (calculated according to the age of patient) is reached. Echocardiogram is done at basal level and after peak dose of dobutamine infusion to see the effect of stress on heart.

HEAD-UP TILT TEST

The tilt table test is a standard and widely accepted test for evaluating patients with syncope. It provides diagnostic evidence indicating susceptibility to neurally mediatd syncope.

This test is performed by tilting the table at 70º angle and observing the patient for 20 min of 70º angle tilt with and without provocation with medicine.

24 HOURS ABPM

24 hours Ambulatory BP monitoring checks the blood pressure of patient multiple times in a day (typically more than 30 readings are taken). The instrument is like a normal BP Apparatus and is worn by patient for 24 hours at home. It gives much better idea about blood pressure of patient and effectiveness of medicines and also aids in diagnosing patients with masked hypertension and white coat hypertension.

TAVI/TAVR (Transcatheter Aortic Valve Implantation/Replacement)

A minimally invasive solution for severe aortic valve stenosis

TAVI/TAVR is an advanced, minimally invasive heart procedure used to replace a narrowed aortic valve that fails to open properly (aortic stenosis). It is an excellent option for patients who are at intermediate or high risk for traditional open-heart surgery.

Why TAVI/TAVR?

  • No open-heart surgery required
    The valve is replaced through a small puncture in the leg artery.
  • Faster recovery
    Most patients walk within a day and return home within 2–3 days.
  • Reduced risk of complications
    Less blood loss, less pain, and lower infection risk compared to surgery.
  • Improved quality of life
    Patients experience better breathing, more energy, and enhanced daily functioning.

Who is it for?

TAVI/TAVR is recommended for patients with:

  • Severe symptomatic aortic stenosis
  • High or intermediate surgical risk
  • Older age or other health conditions that make surgery risky

A detailed evaluation by our Heart Team (Cardiologists, Cardiac Surgeons, Imaging Specialists) determines your suitability.

How the Procedure Works

  1. A small catheter is inserted through a blood vessel in the groin.
  2. A new artificial valve is guided to the heart.
  3. The new valve is expanded inside the old, diseased valve.
  4. The new valve immediately starts functioning effectively.
