The Nawaloka Heart Centre is the keystone of the hospital; the very first private Healthcare Service Provider to offer Sri Lankans the opportunity to undergo Cardio-Thoracic surgery in the country, our Heart Centre performed its 10,000th open heart surgery in August 2013. This was a milestone in Sri Lanka’s private sector‘s history. Today, thanks to the advance in technology, a person can have an angiographic procedure and walk out within 24 hours. This is available right here, right now, at Nawaloka. As the pioneer in the field, our list of firsts’ is the envy of all who followed. The Heart Centre at Nawaloka has pioneered new technology such as the beating heart surgery, and continues to do so by always offering the people of Sri Lanka the best in heart care.
Cardiac Catheterization is used in heart failure patients because it's one of the most useful and accurate test for diagnosing heart problems. It can detect
Where arteries are narrowed or blocked
The blood pressure inside the heart
The amount of oxygen in the blood
How it is done.
First the patient will consult by the Cardiologist who will perform the procedure. The doctor will explain in detail about the procedures how it is done and its risks.
Cardiac Catheterization is relatively safe. Still there are small risks (less than one person in 250 procedures) like bleeding, infection , allergic reaction to the dye, damage to blood vessels, or kidney failure associated with the procedure. In an average patients, the risks are severe complications such as stroke, heart attack and a death on one person in 1,000 procedures.
Hospital stay is limited to 24 hours.
Most of the patients are conscious during the procedure.
Once inside the Cardiac Catheterization Laboratory, you will be transferred to the Cardiac Catheterization table. Cardiac Catheterizations are done through the artery in the groin area or wrist. (Elbow area) Your groin area and or arm will be cleansed and shaved. You will then be covered with sterile drapes. Next the doctor will anesthetize the area with one or two injections. After that, a small straw sixed tube ( called a sheath) will be inserted into the artery in your groin or arm. A special iodine based X-ray dye is injected into the left main coronary artery and its branches. As the dye is injected, X-rays take pictures of the arteries. The X-ray camera is rotated or moved around the patients to give different views of the coronary arteries. Most patients do not feel anything as due is injected into the coronary arteries.
After pictures of the coronary arteries are obtained ( or sometimes before) , another special catheter is threaded into the heart's left ventricle. Then dye is injected into the left ventricle, allowing the doctors to assess how well it's pumping blood. This picture ( a ventriculogram) also can show if one of the heart valves has become "leaky".
The entire catheterization can take as little as 20 minutes or sometimes more than an hour. The time it takes depends on what measurements are needed during the catheterization and other factors related to your heart's particular anatomy.
After the Cardiac Catheterization
After the procedure, the sheaths that have been placed in your groin or arm will be removed. A nurse or other cath lab team member will compress the puncture area for a time to help the small hole in the artery to close ( form a clot). Then you will have to rest for a few hours to ensure the small hole stays sealed. A special dressing will be done on the groin area or arm at the same time.
Most of the patients can go home next day after the procedure. Because of the invasive procedure and may have been given medicine to relax you, plan on having someone else drive you home.
Following the procedure, the puncture area in your groin may be a little tender. There may be a small, swollen area for a day or two. This may be normal, but if there is a tenderness , pain, swelling or bleeding talk to your cardiologist. It is important to make sure that nothing needs further evaluation. In rare cases the artery does not completely seal or an infection may develop.
PDA - Patent Ductus Arteriosus
There is a communication between the aorta and pulmonary artery in a child at birth which supplies oxygen to the brain when the child is inside the mother. Normally at birth this duct ( communication) closes automatically, but in some babies this does not happen. So an operation is needed to close this duct. It is done through the chest wall ( Thoracotomy).
BT Shunt - Blalock Taussig Shunt
Some children do not have a fully developed pulmonary artery ( this supplies blood to the lungs for oxygenation) so the baby does not have enough oxygen in the blood and the blood is blue ( blue baby). The surgeon can sew a tube into the arteries of the heart to supply blood to the lungs and the baby becomes pink.
CABG - Coronary Artery Bypass Grafts.
Veins from leg, internal mammary artery from the inside of the chest ( mainly from left and sometimes from right) and radial artery from the forearm used to bypass the blocked areas of the coronary arteries of the heart. This can be done using the heart-lung machine ( on pump - heart stopped) or on the beating heart ( off-pump) using an immobilization device called the octopus device.
AVR - Aortic stenosis
The aortic valve, which is the main valve through which blood goes out of the heart to the body, can get narrowed ( Aortic Stenosis) or does not close fully ( Aortic Incompetence / regurgitation). The defective valve is removed and replaced with an artificial valve.
MVR - Mitral Valve Replacement
The mitral valve is another valve in the heart that can undergo the same problems like the aortic valve and needs to be replaced just like mentioned in the AVR.
DVR- Double Valve Replacement
In some patients both the Aortic and Mitral valves are diseased and needs replacement at the same time. This patient will need 2 valves
TVR - Triple Valve Replacement
Very rarely three valves needs to be replaced, In addition to the Aortic and Mitral, the Tricuspid valves needs replacing.There are two types of artificial valves. The Mechanical (metal) valve and the Tissue ( made from animals) valve. The choice of valve depends on the patient's and surgeon's preference.
The conditions below are called congenital defects as they are present at birth
ASD - Atrial Septal Defect
The was between the right and left side of the heart at the atrial level is defective. Commonly called hole-in-heart. An artificial patch or a piece of patient%u2019s, own tissue is used to close this hole.
VSD-Ventricular Septal Defect.
As the ASD but this defect is in the ventricular part of the heart, with a hole between the left and right sides. It is closed in the same way.
This condition has four defects; small pulmonary artery, VSD, large aorta and right ventricular thickening. Surgery is complex and corrects all these defects in one operation.
Admissions will be carried out by the Heart Centre Office for the patients who are coming for Catheterization Procedures and for Open Heart Surgeries.
Emergency admission can be done to the Emergency Treatment Unit through the main Admission Counter of the Hospital. All the information regarding Interventional Procedures and Surgeries are being issued from the Cardiac Office.
