ct coronary angiogram

Iain Mactier, Jonathan R Dalzell, David Carrick
CLINICAL INTRODUCTION: A 50-year-old woman presented with an inferoposterior ST-elevation myocardial infarction (STEMI) and underwent emergency percutaneous coronary intervention (PCI). Angiography revealed acute occlusion of the circumflex and right coronary (RCA) arteries. PCI was uncomplicated. Her medical history included asthma, hypertension and chronic sinusitis.Three months later, she presented with a non-STEMI (NSTEMI), and angiogram showed a new focal stenosis in the left anterior descending artery...

OBJECTIVE: Minimally invasive direct coronary artery bypass for the left thoracic artery on the left anterior descending artery is a safe and less traumatic surgical technique. We retrospectively evaluated long-term outcomes in a large series of patients undergoing minimally invasive direct coronary artery bypass. METHODS: From 1997 to 2016, 1060 patients underwent minimally invasive direct coronary artery bypass: 646 patients (61%) with isolated proximal left anterior descending disease and 414 patients (39%) with multivessel disease as a part of hybrid coronary revascularization or in association with medical therapy...

A 8-year-old Irish ethnicity girl presented with 3 days of fever with right-sided neck swelling which was first thought as acute tonsillitis with right-sided lymphadenitis. She was started on intravenous antibiotics. At day 7 of illness, she was diagnosed to have Kawasaki disease with clinical and biochemical evidence. Echocardiogram at day 9 of illness and subsequently CT cardiac angiogram performed revealed giant aneurysm at the right coronary artery with non-obstructing thrombus seen. The patient then commenced on clopidogrel and continued with a regular dose of aspirin...

BACKGROUND: Patients with recent coronary artery bypass graft (CABG) surgery are at risk for early graft failure, which is associated with a risk of myocardial infarction and death. In the COMPASS (Cardiovascular OutcoMes for People Using Anticoagulation StrategieS) trial, rivaroxaban 2.5 mg twice daily plus aspirin 100 mg once daily compared with aspirin 100 mg once daily reduced the primary major adverse cardiovascular events (MACE) outcome of cardiovascular death, stroke, or myocardial infarction...

RATIONALE: Coronary perforation leading to fistula directed to the right ventricle is a rare complication of percutaneous coronary intervention (PCI). The reported outcomes vary from a stable state to rapid deterioration. PATIENT CONCERNS: An 86-year-old man was diagnosed with non-ST elevation myocardial infarction, and arranged to PCI procedure for the chronic total occluded right coronary artery (RCA) after coronary angiography. The guide wire went through the occluded lesion and got to the distal part of the suspected "post lateral artery", which later proved to be in the right ventricle (RV)...

We report a case of a ruptured coronary artery aneurysm associated with coronary artery fistula. A 63-year-old man was suffering from cardiac tamponade due to a ruptured coronary artery aneurysm. An emergency operation was performed to repair the aneurysm. Under cardiopulmonary bypass, all inlet and outlet vessels were sutured and closed. The patient recovered uneventfully. A postoperative coronary computed tomography(CT) angiogram showed extinction of the aneurysm.

We report a 14-year-old boy finally diagnosed with sitosterolemia, presenting with severe aortic valve stenosis. Genetic analysis revealed homozygous null mutation c.1336 C > T (p.R446X) in ABCG5 gene. His cardiac ultrasound presented aortic valve stenosis and moderate aortic regurgitation. His whole aorta computed tomography angiogram scan revealed aortic stenosis superior to the aortic valve, followed by ascending aorta dilation, whereas his coronary and peripheral arteries appeared normal. His maximum total cholesterol and low-density lipoprotein-cholesterol levels dropped dramatically after diet control, and ezetimibe was prescribed for treatment...

The patient was a 60-year-old male fell whose head and left chest hit the ground after falling from a height of 2 m. He complained of the left shoulder and chest pain after regaining consciousness. On arrival, he showed left bloody otorrhea, left chest tenderness, and a limited range of motion due to the left shoulder pain. Emergency chest roentgenography revealed multiple left rib fractures, left clavicular fracture with decreased radiolucency in the left lung field, suggesting lung contusion. When the patient was being transported for computed tomography, he suddenly displayed ventricular tachycardia with pulse and subsequently became VF storm, which required percutaneous cardiopulmonary support...

High-quality cardiopulmonary resuscitation (CPR) is crucial for survival from cardiac arrest. However, various chest compression-associated injuries have been reported. Internal mammary artery (IMA) injury is one of the rare complications after CPR, and most of cases include rib and sternum fractures. In this report, we describe a rare case of IMA injury without chest wall fractures after CPR. An 85-year-old man with a history of acute myocardial infarction 2 weeks prior visited to our hospital for sustained ventricular tachycardia (VT)...

Chest pain can be a challenging complaint to manage in the emergency department. A missed diagnosis can result in significant morbidity or mortality, whereas avoidable testing and hospitalizations can lead to increased health care costs, contribute to hospital crowding, and increase risks to patients. The HEART score is a validated decision aid to identify patients at low risk for acute coronary syndrome who can be safely discharged without admission or objective cardiac testing. In the largest and one of the longest studies to date (N = 31,060; 30 months), we included the HEART score into a larger, newly developed low-risk chest pain decision pathway, using a retrospective observational pre/post study design with the objective of safely lowering admissions...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial ischemia. Identification of intimal flap, true and false lumens in coronary angiogram (CAG) is the standard method to diagnose SCAD. In cases of obscure intimal flap, intravascular ultrasound (IVUS) is a useful method to diagnose, although crossing the wire and IVUS in the dissected lesion is invasive. Multidetector computed tomography (MDCT) provides valuable information in any clinical setting less invasively. We report here a rare case of spontaneous dissecting coronary artery pseudoaneurysm diagnosed by CAG and MDCT, healed by medical treatment, and followed up by MDCT over a 2-year period...

Congenital coronary anomalies are uncommon and are mostly asymptomatic; however, patients may have symptoms depending on the origin and course of anomalous artery. Very rarely, coronary anomalies can also lead to life-threatening complications especially in young athletes. A malignant course of the left main (LM) or left anterior descending (LAD) artery between aorta and pulmonary artery is considered the most significant risk factor for such complications. Various noninvasive tests are available to evaluate myocardial ischemia due to anomalous coronary artery...

BACKGROUND: Various investigations have reported that the internal mammary artery (IMA) is an efficient and functional choice of conduit for vascular graft surgeries, especially for coronary artery bypass grafts; however, the quest to find an ideal vascular substitute remains. We hypothesized that acellular IMA could be an appropriate graft for small-diameter vascular bypasses that could be used in various surgeries including coronary artery bypass grafting. METHODS: We decellularized human IMAs and performed histologic evaluations and scanning electron microscopy to confirm the decellularization process and the preservation of the extracellular matrix...

Anomalous origin of left coronary artery (LCA) from the right coronary cusp with an intramural course is usually managed with unroofing of the intramural segment. Available literature demonstrates an uneventful course following surgery in most patients. Coronary stenosis following the unroofing procedure treated with percutaneous coronary intervention has not been described in the past. We describe a case where an 11-year-old girl with anomalous origin of the LCA from the right coronary cusp presented with near syncope...

Coronary artery anomalies have been reported in Bulldogs and present an increased risk when performing balloon valvuloplasty. Identification of coronary anomalies has been reported using multidetector-row computed tomographic (MDCT) angiography with electrocardiographic gating. However, the utility of non-electrocardiographic-gated 16-row computed tomographic for MDCT for the identification of coronary artery anatomy or anomalies to the authors' knowledge has not been fully investigated. The purpose of this study was to evaluate the feasibility of non-electrocardiographic-gated computed tomographic (CT) angiography to identify coronary anomalies in Bulldogs with pulmonary valve stenosis...

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...
