1.1.1.2 Percutaneous trans-luminal coronary angioplasty
The accumulation of lipid in blood vessel wall is called arteriosclerosis;
when it occurs, the blood low through the vessel reduces producing
ischemia. Myocardial ischemia produces a chest pain called angina.
Percutaneous trans-luminal coronary angioplasty aims improving
