Coronary angioplasty also called percutaneous coronary intervention or Percutaneous transluminal coronary angioplasty (PTCA), is a process to open blocked heart vessels. Angioplasty includes temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery.
Angioplasty is combined with the stent (permanent placement of a small wire mesh tube) to help & support the artery open and also to decrease the chances of getting narrow again. Few stents are coated with medicines called drug-eluting stents to help keep your vessels open, and few are not, called ‘bare-metal stents’.
You can see improvement in symptoms related to jammed arteries, like chest pain and breathlessness. Angioplasty can also be used during a heart attack to quickly open a blocked artery and reduce the amount of damage to your heart.
