Coronary angioplasty through Radial approach, Rotablation
Coronary angioplasty is a minimally invasive, non-surgical procedure. It is performed to open the blocked coronary (heart) arteries and restore blood flow to the heart muscle. The procedure involves the removal of waxy substance called plaque which accumulates inside the coronary arteries over the years. The condition is called coronary heart disease (CHD) or coronary artery disease. Over the years, Coronary Angioplasty has become an increasingly popular and effective alternative to bypass surgery for being safer and cost-effective. Typically, a coronary angiogram involves placing catheters into the femoral artery, directing them into the blood vessels supplying the heart, and injecting contrast dye to visualize the vessels. When the groin is used for arterial access, patients might be required to lie down for six hours to complete the procedure.
The Radial method is one of the latest approaches being used to perform Coronary Angioplasty. One of the great advantages of the procedure is that after 10 minutes, the patients have a greater amount of freedom of movement than they had previously with the femoral technique. Prior to the procedure, the patient usually receives some sedation. This helps in keeping the patient relaxed. After numbing the wrist, the physician inserts a micropuncture needle inserts a guidewire, targeting the brachial artery under fluoroscopy. Next in is the sheath, through which the doctor places the catheters. Angiograms normally require at least two catheters to track the right-sided and left-sided vessels to the heart. Once finished, the doctor removes the catheter and places a band on the radial artery to compress the blood vessel. The patient is then left to take proper rest.
The procedure involves a very small device called a Rotablator. It is the shape of a tiny football and comes in many sizes to suit various arteries. It is threaded over a guidewire through the catheter that is used to inject dye at the blockage site.
