Coronary artery fistulas are rare congenital anomalies usually discovered incidentally on imaging studies. Coronary artery pseudoaneurysms are unusual complications of coronary artery fistulas, which can be due to atherosclerosis, inflammatory, traumatic or iatrogenic causes. We present a case of a 55 year old female with no known atherosclerotic risk factors, history of trauma or connective tissue disease referred because of recurrent palpitations. Work ups revealed a cardiac mass with an initial assessment of pericardial cyst...

INTRODUCTION & OBJECTIVES: The utility of the Agatston calcium scoring method has been described extensively in the coronary circulation, but to date has not been investigated in the extracranial carotid domain. We sought to evaluate this calcium scoring method in its ability to predict carotid plaque vulnerability. METHODS: We retrospectively reviewed all computed tomography angiogram (CTA) studies of the carotid arteries performed between March 2012 and March 2017 at a single institution...

A 62-year-old Caucasian man with past medical history significant for coronary artery disease, status post drug eluting stent to the left anterior descending artery 10 years prior, was admitted for elective total right knee arthroplasty. His intraoperative course was uneventful, and he was discharged on hospital day 2 on aspirin 325 mg twice daily for 6 weeks for venous thromboembolism (VTE) prophylaxis. Three weeks later the patient developed chest pain shortly after an approximately 1-hour flight and presented to a local emergency department where computed tomography angiogram showed pulmonary emboli involving segmental and subsegmental pulmonary arteries bilaterally...

A 58 year-old man was admitted in our ICU for cardiogenic shock and electrical storm. His medical history was marked by a triple redo valvular surgery complicated by a recurrent aortic pseudoaneurysm of the ascending aorta. Coronary angiogram and heart CT scan diagnosed an extensive anterior myocardial infarction related to an extrinsic compression of the left main stem by this massive and calcified pseudoaneurysm. Angioplasty or new cardiac surgery options were rejected by the heart team. Despite an unusual indication, the patient was registered on the heart transplant list, and underwent it successfully...

We aimed to evaluate the impact of tissue characterization for in-stent restenosis (ISR) with optical computed tomography (OCT) during excimer laser coronary angioplasty (ELCA) in the drug-eluting stent (DES) era. The effect of ELCA for ISR according to differences in tissue characteristics is unclear. Fifty-three ISR lesions (7 bare metal stents and 46 drug-eluting stents) were treated with an ELCA catheter. After ELCA, balloon dilatation with either the scoring or non-compliant balloons was conducted. The procedure was completed by applying a drug-coated balloon...

Although the majority of acute chest pain patients are diagnosed with noncardiac chest pain after noninvasive testing, identifying these low-risk patients before testing is challenging. The objective of this study was to validate the coronary artery disease (CAD) consortium models for predicting obstructive CAD and 30-day major adverse cardiovascular events (MACE) in acute chest pain patients considered for coronary computed tomography angiogram, as well as to determine the pretest probability threshold that identifies low-risk patients with <1% MACE...

BACKGROUND: The aim of this study was to develop and describe percutaneous coronary angiographic techniques to create a porcine model of acute coronary stenosis with methacrylate plugs that can by assessed using fractional flow reserve (FFR), invasive coronary angiography and coronary computed tomographic (CT) perfusion imaging without introducing artefacts associated with surgical models. METHODS: Following animal care and institutional approval and using percutaneous coronary catheterisation techniques within an animal laboratory we introduced precision drilled methacrylate plugs into one of the three main coronary arteries of 10 experimental female pigs...

Congenital Bochdalek diaphragmatic hernia (DH) is often diagnosed incidentally in adulthood. It is recommended that all cases of DH be repaired immediately at diagnosis since acute presentation after the complications have already developed has higher morbidity and mortality. A 47-year-old male presented with Grade III angina and dyspnea. A routine chest radiograph revealed bowel shadows in the right thorax, and subsequent computerized tomography (CT) scan confirmed the same. Coronary angiogram revealed coronary artery disease which needed surgery...

An anomalous aortic origin of coronary artery is a cause of sudden death in young people. We report a surgical case of an anomalous aortic origin of the left coronary artery. A 16-year-old man with chest pain, which occurred while playing football, was taken in an ambulance. Electrocardiogram (ECG) revealed an ST-segment elevation in V1-V5. We performed coronary angiogram (CAG) and detected the anomalous aortic origin of left anterior descending artery. The computer tomography( CT) angiography revealed the intramural pathway of the left coronary artery...

There are many variations of coronary anatomy encountered during coronary angiogram. Anatomy demonstrating a single coronary artery is a rare congenital coronary artery anomaly. The entire heart is supplied solely by a coronary artery with single coronary ostium. We present a rare case of single coronary artery arising from the right sinus of Valsalva. The patient had presented with atypical chest pain and a stress test was performed, which was abnormal. We proceeded with coronary angiography which showed a common ostium of the right and left coronary artery coming from the right coronary cusp...

Although rare, usually asymptomatic, and without concurrent disease, dual left anterior descending arteries (LAD) poses great challenges. We describe a 55-year-old male with no history of coronary disease, who presented with worsening substernal chest pain with exertion, and was ruled out for myocardial infarction. On left heart catheterization and subsequent computed tomography angiogram, he was determined to have a dual LAD with a long LAD emerging from the right coronary artery. Moreover, this long LAD gave collaterals to a native long diagonal that ran parallel to this vessel from the left system and was chronically occluded...

CLINICAL INTRODUCTION: A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0...

OBJECTIVE: Robotically assisted minimally invasive direct coronary artery bypass is an alternative to sternotomy-based surgery in properly selected patients. Identifying the left anterior descending artery when it is deep in the epicardial fat can be particularly challenging through a 5- to 6-cm mini-thoracotomy incision. The objective of this study was to evaluate a technique for predicting conversion to sternotomy or complicated left anterior descending artery anastomosis using preoperative cardiac-gated computed tomography angiograms...

Left-sided inferior vena cava (IVC) is the second most common anatomical anomaly of the IVC. We report a drainage pattern of the left IVC into a left duplicated superior vena cava (SVC) diagnosed during IVC filter placement consultation. The patient was a 66-year-old man with symptomatic hematuria caused by bladder cancer diagnosed with IVC thrombus and a left IVC found on a staging computed tomography urogram. The patient underwent computed tomography pulmonary angiogram, which ruled out pulmonary embolism, but demonstrated hemiazygous continuation of the left IVC above the diaphragm to meet a persistent left SVC (prevalence approximately 0...

A 68-year-old male presented to the emergency department with retrosternal chest pain, presyncope, and then a pulseless electrical activity cardiac arrest. An ECG prior to his arrest revealed ST elevations in leads V1-V3, Q waves in lead V2, and reciprocal ST depressions in the lateral and inferior leads. He received thrombolytic therapy for a presumptive diagnosis of ST elevation myocardial infarction. Return of spontaneous circulation was achieved and he underwent a coronary angiogram. No critical disease was found and his left ventriculogram showed normal contraction...

Objective Transoesophageal echocardiography (TEE) is the gold standard for the detection of cardiac emboli sources in ischaemic stroke patients, but new computed tomography (CT) scanners are able to visualize the heart. This pilot study aimed to compare findings on TEE with combined cardiovascular scan and cerebral CT angiography in cryptogenic ischaemic stroke patients. Methods This pilot study enrolled patients with cryptogenic ischaemic stroke who underwent a combined cardiovascular and cerebral CT angiography scan and a TEE examination, which were interpreted in a blinded manner...

Iatrogenic aortic dissection caused by primary percutaneous coronary intervention (PCI) is a rare but potentially fatal complication; therefore prompt recognition of this life-threatening condition is crucial. We present herein a case of a 70-year-old lady who underwent primary PCI for transmural myocardial infarction of left anterior descending artery territory. Manipulation of the extra backup (EBU) guiding catheter during an attempt to cannulate the left system resulted in an aortic dissection. The patient was managed conservatively with strict monitoring in the coronary care unit (CCU), and underwent serial evaluation with non-invasive imaging studies including a computed tomography angiography (CTA)...
