Coronary angiography is an imaging technique or a radiological test that helps visualize the insides of the coronary arteries. It shows the exact location and severity of any plaque formation and consequent narrowing of the coronary arteries. This helps the doctor to decide on what treatment is needed.
The test is commonly carried out within the Cath lab in a hospital set up. The procedure normally takes around 15 to 20 minutes.
What are the preparations for Coronary angiography?
Patients who are prescribed this test need to be admitted to the hospital on the day of the test. Sometimes admission on the previous evening and a stay overnight may also be advised. A few hours of fasting with nothing taken via mouth (including water) is recommended.
What are the implications of an angiography results?
Normal result of coronary angiography means that there is adequate blood supply to the heart. Abnormal result on the other hand means that one or more coronary arteries may be blocked or narrowed in one or more places. The degree or percentage of each block is also reported. If the narrowing of the arteries is mild, it can be treated with medicines alone. If the arteries and their branches are more severely occluded and narrowed, coronary artery bypass graft or coronary angioplasty may be required.
Angioplasty is a specialised procedure performed in a Cath lab (cardiac catheterisation laboratory). Since the patients are awake and alert through the procedure, they are given medication before and during angioplasty procedure to help relax
Our heart is located in our chest cavity and is a pump made of special muscles known as myocardium. Our heart is divided into four chambers; two upper chambers known as auricles (atria) and two lower chambers are known as ventricles. They are interconnected by a passage and the opening and closing is controlled by valves.
Arteries, veins and lymphatic vessels form the vascular system of our body and vascular surgery is a specialty dealing with diseases affecting the vascular system The diseases affecting our vascular system involve the obstruction in the blood flow due to blockages (aneurysms) in the vessels.
The rhythmicity of the heart beat is based on the electric impulses. These impulses are initiated by the contraction of the cardiac muscles also known as myocardium.
Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD). Symptoms of coronary artery disease include chest pain, fatigue, palpitations, abnormal heart rhythms and shortness of breath.
A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side.
The upper chambers of the heart are divided a wall called “interatrial septum”. The defect in this wall is known as Atrial septal defect (ASD). It is a form of a congenital heart defect, the defect the baby is born with.
