Pseudo-lesions of a Tortuous Right Coronary Artery During Percutaneous Coronary Intervention: Accordion Phenomena
نویسندگان
چکیده
Guidewire-induced pseudo-lesions are referred to accordion phenomenon and are infrequent occurrences during percutaneous coronary intervention of tortuous coronary arteries. Their occurrence can be a diagnostic challenge to the interventionist and might lead to unnecessary intervention. Ischemia and hemodynamic compromise are possible complications, if not managed promptly. The differential diagnosis includes coronary dissection, thrombus, and spasm. We describe a patient who developed pseudo-lesions of the tortuous right coronary artery in multiple segments during PCI. The pseudo-lesions were refractory to intracoronary nitrogycerin.

Severe accordion effect: Myocardial ischemia due to wire complication during percutaneous coronary intervention: A case report
A mechanical alteration during manoeuvring of stiff guidewires in tortuous coronary arteries frequently induces vessel wall shortening and coronary psedostenosis, referred as accordion phenomenon. Subtraction of the guidewires normally leads to the entire resolution of the lesions. A case of this transient angiographic finding, during percutaneous coronary intervention in a tortuous right coron...
متن کاملCoronary accordion effect mimicking coronary dissection
The coronary "accordion" effect is a rare pseudo-complication of percutaneous coronary intervention (PCI). It is usually observed due to straightening and shortening of tortuous vessels with stiff guidewires during PCI. In this case report, we present an interesting case of the coronary accordion effect observed in a 52-year-old woman undergoing PCI.

متن کاملPseudo dislodgement of a stent due to crumpling of a coronary artery: a hitherto unreported complication of the "accordion effect".
The "accordion effect" is a mechanical remodeling of the arterial wall produced by endoluminal introduction of stiff guidewires, leading to vessel wall shortening and development of multiple eccentric constrictions. This phenomenon is unresponsive to vasodilators and may lead to unnecessary stenting of the pseudo-lesions. It must be suspected with the development of multiple lesions and when a ...
متن کاملA case with successful retrograde stent delivery via AC branch for tortuous right coronary artery.
The retrograde approach is a novel technique of percutaneous coronary intervention for chronic total occlusion. This technique has improved the success rate of guidewire passage through the occlusion. In the retrograde approach, a microcatheter and balloon are delivered through a retrograde channel. However, it is difficult for a stent to pass through collateral arteries. We report a case of co...
