Prevention of coronary perforation

Sr. NoDeviceMethods to avoid perforation
01Angioplasty balloonLow balloon: artery ratio, avoid high-pressure pre-dilatation
02StentAvoid high-pressure initial inflation and oversizing in heavy calcification Post-dilate the stent
03Stiff wiresCareful distal navigation to avoid side branch
Maintain tip mobility to avoid subintimal space
04Rotational atherectomyArtery ratio (<0.8)
Avoid angulated segments
