Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist, Dr. Charles Dotter.A large number of procedures can be performed on the heart by catheterization. This most commonly involves the insertion of a sheath into the femoral artery (but, in practice, any large peripheral artery or vein) and cannulating the heart under X-ray visualization (most commonly fluoroscopy). The radial artery may also be used for cannulation; this approach offers several advantages, including the accessibility of the artery in most patients, the easy control of bleeding even in anticoagulated patients, the enhancement of comfort because patients are capable of sitting up and walking immediately following the procedure, and the near absence of clinically significant sequelae in patients with a normal Allen test.

 

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").

Procedures performed by specialists in interventional cardiology:

Angioplasty

Also called percutaneous transluminal coronary angioplasty (PTCA), angioplasty is an intervention for the treatment of coronary artery disease.

Valvuloplasty

It is the dilation of narrowed cardiac valves (usually mitral, aortic, or pulmonary).

Congenital heart defect correction

Percutaneous approaches can be employed to correct atrial septal and ventricular septal defects, closure of a patent ductus arteriosus, and angioplasty of the great vessels.

Percutaneous valve replacement: An alternative to open heart surgery, percutaneous valve replacement is the replacement of a heart valve using percutaneous methods.

Coronary thrombectomy

Coronary thrombectomy involves the removal of a thrombus (blood clot) from the coronary arteries.[3]
