title: [De-novo reversible stenoses in tortuous arteries during coronary angioplasty due to the accordion effect. A clinical case and review of the literature].
abstract: During the performance of PTCA, the operator must be able to differentiate true complications from pseudocomplications. Mechanical coronary shortening and vessel wall invagination due to accordion effect, "pseudo-transection", dissection, coronary spasm, and localized thrombosis are sources of iatrogenic obstruction during angioplasty. We report a case in which straightening of a right tortuous coronary artery during angioplasty produced an iatrogenic lesion that has a typical invaginate appearance. Conservative management is indicated in the absence of definitive angiographic aspect of vessel trauma, because they disappear after withdrawal of angioplasty equipment or adequate management of the guidewire.
