A 43-year-old woman underwent radiofrequency pulmonary vein ablation for symptomatic paroxysmal atrial fibrillation. At 3 months, she developed worsening dyspnea and exercise intolerance; tests revealed severe stenosis in her right pulmonary veins at…
Angiography at 60 mo. post implantation of an Absorb bioresorbable vascular scaffold (Abbott Vascular) revealed a total occlusion at the distal scaffold. Within the proximal edge, OCT showed complete absorption of stent struts with a decreased mean s…
A 24-year-old male presented to hospital following syncope with electrocardiographic changes and was found to have left main coronary artery occlusion requiring emergent coronary artery bypass grafting.
Accordion effect or concertina effect — also known as “crumpled coronary” — is an uncommon occurrence during coronary angioplasty. It usually has no major clinical sequelae and should be differentiated from spasm, dissection, and thrombosis, which re…
After a series of tests, an 86-year-old patient was shown to have an infected thrombus on a TAVI valve and was referred to urgent surgery. The valve with the infected thrombus was removed and a biological prosthetic valve was implanted in its place.
The Absorb bioresorbable vascular scaffold (Abbott Vascular) does not have an artifact on computed tomography coronary angiography (CTCA); the extent/location of the stent in situ can only be assessed by localizing its radiopaque platinum markers in…
Intra-arterial injection of recreational substances and drugs is less well described in the literature. It carries a risk for hand ischemia and embolization to the hand digits and ultimately amputation.
This study examined the accuracy of machine learning in predicting bleeding outcomes post percutaneous coronary intervention (PCI) in comparison with the American College of Cardiology CathPCI bleeding risk model. Mayo Clinic CathPCI registry data we…
