Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. The main advantages of using the interventional cardiology or radiology approach are the avoidance of the scars and pain, and long post-operative recovery.
Additionally, interventional cardiology procedure of primary angioplasty is now the gold standard of care for an acute myocardial infarction. It involves the extraction of clots from occluded coronary arteries and deployment of stents and balloons through a small hole made in a major artery, which has given it the name "pin-hole surgery" (as opposed to "key-hole surgery").
Intervention Radiology / Peripheral Vascular
Interventional radiology is a medical sub-specialty of radiology which utilizes minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system. The concept behind interventional radiology is to diagnose and treat patients using the least invasive techniques currently available in order to minimize risk to the patient and improve health outcomes.
As the inventors of angioplasty and the catheter-delivered stent, interventional radiologists pioneered modern minimally-invasive medicine. Using X-rays, CT, ultrasound, MRI, and other imaging modalities, interventional radiologists obtain images which are then used to direct interventional instruments throughout the body. These procedures are usually performed using needles and narrow tubes called catheters, rather than by making large incisions into the body as in traditional surgery.
Interventional Non Vascular
Non-vascular interventions are minimally invasive interventional radiology procedures that do not involve blood vessels. The physician uses imaging technology to guide instruments inside the body without open surgery.
Interventional radiologists often use ultrasound and CT scans to guide catheter (tube) placement to drain abscesses and other fluid collections. Imaging technology is also used for biopsies of deep tumors in the chest, abdomen and pelvis.
