Dr. Nadir Ali's Treatments and Specialties

Dr Ali has been providing consultation and treatment for a wide range of heart conditions ranging from minor ectopics to critical surgical procedures. Some of his core specialization include:

Congenital Heart Defects

Congenital Heart Defects

Conditions related to the with the structure of the heart are classified together under Congenital Heart Defects. It typically involves the walls of the heart, the cardiac valves and the arteries and veins connected to the heart. In the majority of cases, these are the most common type of birth defects. Early diagnosis and prevention can prove to be significant in expanding the life span of the suffering patients.

Coronary Artery Disease

Coronary Artery Disease

Coronary Artery Disease (CAD) is one of the most wide-spread cardiac conditions, both in adults as well as pediatric patients. Narrowing or blockage of the coronary arteries due to atherosclerosis is the most common cause. Early detection can prevent plaques buildup and fatty deposits chocking the inner walls of the artery. Surgical procedures can also be effective in dealing with CAD conditions.

Heart Rhythm Disorders

Heart Rhythm Disorders

Commonly known as Ectopics, skipped heart beats can be pretty dangerous if left unattended for an extended period. It can lead to a wide range of heart rhythm disorders, including causing serious damage to the sinus node, also known as the heart's pacemaker. Atrial Fibrillation, or AFib/AF, is one such chaotic condition, which can cause blood to stagnate and form clots - resulting in cardiac stroke even in young patients.



Angioplasty, also called percutaneous coronary intervention, is a procedure to cure Coronary Artery Diseases. It uses a tiny balloon catheter that is inserted in a blocked blood vessel to help widen it, thus helping to restore normal blood flow through the blocked/clogged artery. In some cases, a stent may also be placed inside the blocked vessel during angioplasty to prevent the inner walls from getting clogged repeatedly.

Cardiac Catheterization

Cardiac Catheterization

Cardiac catheterization is a procedure used to diagnose and treat certain cardiovascular conditions. As part of the procedure, a long thin tube (catheter) is inserted in an artery or vein from the groin, neck or arm and it is threaded through the blood vessels connected to the heart. It's not a curative procedure, but rather a dignostic one to find out if the patient has disease of the heart muscle, valves or coronary arteries.

Cardiac Stress Test

Cardiac Stress Tests

Cardiopulmonary exercise test (CPX) is used to measure the heart's ability to respond to external stress in a controlled clinical environment. Because physical activity makes the heart pump harder and faster, a stress test can reveal problems with blood flow within the heart. This test is prescribed to patients with the symptoms of coronary artery disease or an irregular heart rhythm to find out what extent of stress the heart is capable of tolerating.


Supraventricular Tachycardia

Commonly known as SVT, Supraventricular Tachycardia means fast heartbeat that originates from somewhere above the ventricles or the top chambers of the heart. SVTs are common in young people, especially in children and adolescents. It is typically caused by a single abnormal electrical short circuit within the heart and in most cases curable upon proper treatment.


Pacemakers & IDCs

A pacemaker or ICD (Implantable Cardioverter Defibrillator) is used to counter slow heart rhythms. With increasing age coupled with other cardiac conditions, the sinus node in the heart can sometimes become weaker and unable to take the regular work-load. This condition is clinically known as bradycardia. Pacemaker implantation can be the most effective measure to prevent bradycardia as it uses electrical pulses to prompt the heart to beat at a normal rate.



Cardioversion is a procedure done to get back a fast heart rate (commonly known as tachycardia) to its normal state using electricity. While it is also possible to do this using drugs it is commonly done by sending electricity to your heart through electrodes placed on the chest. This procedure is necessitated as sometimes the electrical signals which make your heart beat at its normal rate do not travel properly through the heart chambers.
