Successful Bailout of Catheter-Induced Dissection in Acute Myocardial Infarction Resulting From a Nondominant Right Coronary Artery Occlusion.

ABSTRACT: A 48-year-old male with a history of hyperlipidemia presented to the emergency department with chest pain. Electrocardiographic abnormalities indicated an acute coronary syndrome. Urgent coronary angiography revealed nondominant right coronary artery (RCA) occlusion. During primary percutaneous coronary intervention (PCI), a 0.014-inch floppy guidewire could not be easily advanced into the middle RCA due to poor backup support from the guiding catheter and the patient's breathing. The pressure was monitored several times after reinserting the guiding catheter. Nevertheless, the guidewire was inadvertently inserted into the false lumen from the ostium, leading to subsequent dissection during contrast injection. Intravascular ultrasound (IVUS) imaging confirmed dissection from the ostium to
