clot using anticlotting called clot-busters, such as tissue plasminogen activator
Angioplasty
Any Endovascular procedure that reopens narrowed blood vessels and restores forward blood flow
Percutaneous transluminal coronary angioplasty

Arterial
Removal of a segment of an arterial vessel wall to confirm inflammation of the wall or arteries, a type of vasculitis
Catheter ablation
Treatment for cardiac arrhythmias; Usually performed under fluoroscopic guidance
Commissurotomy
Surgical separation of the leaflets of the mitral valve, which have fused together at their points of contact(commissures)
Coronary artery bypass graft (CABG)
Placement of a vessel graft from another part of the body to bypass the block part of a coronary artery and restore blood supply to the heart muscle
Embolectomy
Removal of an embolus
Endarterectomy
Removal of fatty plaque from the interior of an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
Automatic implantable cardioverter-defibrillator (AICD) insertion
implantation of a battery powered device that monitors and automatically corrects ventricle tachycardia or fibrillation by sending electrical impulses to the heart in patients who are at risk of sudden cardiac death; also Called implantable cardioverter-defibrillator
Laser ablation
Procedure used to remove or treat varicose veins
Open heart surgery
Surgical procedure performed on or within the exposed heart, usually with the assistance of a heart- lung Machine
Stent placement
Placement of a mesh tube inserted into a natural passage or conduit in the body to prevent or counteract a disease- induced, localized flow constriction
Valvotomy
Incision of a valve to increase the size of the opening; used in treating mitral stenosis
Cardiac catheterization(CC)
Passage of a catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart
