| ==Overview==
| |
| The [[coronary angiogram]] is fairly insensitive to the presence of [[lesion]] [[calcification]], particularly the presence of deep [[vessel]] wall [[calcification]]. [[Intravascular ultrasound]] is much more sensitive in the assessment of [[vessel]] wall [[calcification]]. Conventional [[coronary angiography]] has limited [[sensitivity]] for the detection of smaller amounts of [[calcium]], and has moderate [[sensitivity]] for the detection of extensive [[lesion]] [[calcium]] ([[sensitivity]] 60% and 85% for three- and four-quadrant [[calcium]], respectively).<ref name="pmid7895353">{{cite journal |author=Mintz GS, Popma JJ, Pichard AD, ''et al.'' |title=Patterns of calcification in coronary artery disease.

Failure to fully expand the [[stent]] may result in [[restenosis]]. [[Stents]] should be deployed only after ensuring that the [[lesion]] can be fully expanded by a conventional balloon [[angioplasty]].
