Prevention of coronary perforation
| Sr. No | Device | Methods to avoid perforation |
|---|---|---|
| 01 | Angioplasty balloon | Low balloon: artery ratio, avoid high-pressure pre-dilatation |
| 02 | Stent | Avoid high-pressure initial inflation and oversizing in heavy calcification Post-dilate the stent |
| 03 | Stiff wires | Careful distal navigation to avoid side branch Maintain tip mobility to avoid subintimal space |
| 04 | Rotational atherectomy | Artery ratio (<0.8) Avoid angulated segments |
