Defining Coronary Artery Perforation with Ultrasound Contrast Agent

Triphasic Contrast Agent Injection in 64-MDCT Coronary Artery Angiography

Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...

Mass Confusion: Defining Aortic Pathology With Ultrasound Contrast.

coronary artery perforation after guidewire removal

coronary artery perforation is a rare, but potentially serious, complication of percutaneous coronary intervention and is associated with a high incidence of death, q-wave myocardial infarction, and emergency coronary bypass surgery. management is different but requires prompt recognition and treatment. we describe a case of coronary perforation only after guidewire removal and also review the ...

Coronary artery perforation treated with multiple bare metal stent implantation

Although coronary artery perforations are quite rare, when they occur, the consequences are devastating. Treatment options differ according to the type, location and severity of the perforation. As a general rule severe perforations are treated with covered stents. However, when implanting a covered stent is not an option as in our case due to various reasons, multiple bare metal stent implanta...

Fatal Delayed Coronary Artery Perforation After Coronary Stent Implantation

Most type I and II perforations are predominately caused by hydrophilic and stiff wires, often presented in the delayed form, and do not require pericardial drainage or surgical interventions. However, we report a type III delayed coronary artery perforation at the site of stent implantation after intervention without any evidence of immediate perforations. To the best of our knowledge, this is...
