Abstract: The management of cardiac arrest during coronary angiography and intervention presents substantial challenges. Patients presenting with ST-segment elevation myocardial infarction or following resuscitation from cardiac arrest are at greatest risk and may represent a significant portion of patients in some centers. Timely and effective cardiopulmonary resuscitation (CPR), with manual chest compressions is the primary mode of support though novel circulatory assist devices may have some role.
Rapid Progression of Coronary Aneurysm to Stenosis in a Patient with Kawasaki Disease

Abstract: In Kawasaki disease, coronary aneurysms typically regress slowly, although some may develop stenosis 1-2 decades after the acute illness. This is the first case report describing rapid progression of coronary aneurysm to stenosis within 14 weeks.

False Left Ventricular Apical Aneurysm — A Rare Complication After Transapical Aortic Valve Replacement

Abstract: We report on a case of a false aneurysm at the access site after transapical aortic valve replacement. Although this is not the first case report about this issue, our case emphasizes the importance of follow-up echocardiography after transapical aortic valve replacement that focuses not only on prosthesis function, but also on detecting probable complications of the surgical access site.

A 59-year-old man underwent placement of an intra-aortic balloon pump (IABP) in anticipation of coronary artery bypass graft surgery. While the patient was in the cardiac catheterization laboratory, the IABP malfunctioned. Attempts to advance a 0.025-inch guidewire through the IABP guidewire lumen were unsuccessful (the wire entered the IABP helium chamber, arrow, panel A).
Pulseless Right Groin… Bounding Distal Pulses

Unusual anatomic variants are rare and can sometimes mimic atherosclerotic peripheral vascular disease. In the case described, physical examination revealed a pulseless right groin yet palpable dorsalis pedis and posterior tibial pulses. During peripheral angiography, numerous attempts at gaining right common femoral arterial access were unsuccessful. A persistent sciatic artery was identified.
An Atypical Case of Acute Myocardial Infarction

ABSTRACT: Most ST-elevation myocardial infarctions are related to atherothrombosis and benefit from emergent percutaneous coronary intervention. On the other hand, type-A aortic dissection is a less frequent but deadly disease requiring emergent surgery. In the present case, we aimed to report the case of a patient who presented with aortic dissection responsible for STEMI and cardiogenic shock related to a compressive hematoma of the left main trunk.

ABSTRACT: We present three cases of a single coronary artery that is the anomalous RCA originating from the mid LAD artery. These cases are rare. We discuss how to make accurate diagnosis and select appropriate treatment.

A 59-year-old man with a history of hypertension, family history of premature coronary artery disease and atypical chest heaviness was referred to exercise stress test. After achieving 89% target heart rate at a workload of 9 metabolic equivalents using Bruce protocol, 1–1.5 mm horizontal ST depressions were seen in the lateral leads.
Thrombus Contribution to Very Late Restenosis of Bare-Metal Stent Treated by Excimer Laser Angioplasty: In Vivo Assessment with Optical Coherence Tomography

A 75-year-old, male ex-smoker with hypertension and family history of ischemic heart disease, previous anterior myocardial infarction, and angioplasty with bare-metal stent implantation to the left anterior descending artery 4 years earlier, developed effort angina. A nuclear myocardial scan documented a stress-inducible perfusion defect in the left ventricular anterior wall. The patient was taking 100 mg aspirin daily and a 300 mg loading dose of clopidogrel was administered the day before coronary angiography.
Optical Coherence Tomography-Guided Stenting of a Large Coronary Aneurysm: Images at Implantation and at 6 Months

ABSTRACT: Intravascular imaging with optical coherence tomography (OCT) can produce high-resolution images (10–20 µm) of the coronary vessel wall and is being increasingly used to provide insight into coronary pathology and neointima formation following coronary stenting. Fourier domain OCT (FD-OCT) permits a greater scan diameter than time domain OCT and enables larger-caliber coronary structures to be effectively imaged. We present a case of a large, symptomatic and expanding right coronary artery aneurysm treated with FD-OCT-guided pericardial covered stenting and describe the OCT findings immediately after stent deployment and at 6 months.
