Computed tomography (CT)-guided lung biopsy of nodules located near the heart may be associated with potential complications. To understand the influences of cardiac motion on lung parenchyma during biopsy, we processed the cardiac phase images of coronary CT angiography (CCTA) and noticed shifts in mediastinum lung margin (MLM) at different zones.Thirty eight CCTA (27 men and 11 women) were retrospectively evaluated. Image processing was done with Fiji (an open source Java image processing program by Fiji contributors) using 10% to 90% phase images of CCTA; and tissue displacement (MLM shift) was shown on the resulting images...

RATIONALE: High take-off of the coronary arteries is a rare cardiac anatomic anomaly, which may occur independently or with other congenital heart defects. In the clinical setting, it is noteworthy as a cause of sudden cardiac death. Further, it is vital to identify such anomalies to avoid intraoperative catastrophes in surgeries for congenital heart defects. PATIENT CONCERNS: A II/6 systolic heart murmur on physical examination was incidentally found in a 9-year-old boy; he was confirmed to have a secundum-type atrial septal defect on echocardiography...

AIMS: Shift work disrupts the normal circadian rhythm and is associated with risk factors for coronary artery disease (CAD) and a higher incidence of CAD morbidity and mortality. Cardiac computed tomography angiography (CCTA) is a robust noninvasive modality for assessing the presence, extent, and severity of CAD. We sought to investigate whether shift workers are prone to a higher burden of CAD compared to non-shift workers. METHODS: We conducted a historically prospective study in consecutive patients who underwent CCTA and answered a telephonic questionnaire...

Early identification of atherosclerosis and at-risk lesions plays a critical role in reducing the burden of cardiovascular disease. While invasive coronary angiography serves as the gold standard for diagnosing coronary artery disease, non-invasive imaging techniques provide visualization of both anatomical and functional atherosclerotic processes prior to clinical presentation. The development of cardiac positron emission tomography (PET) has greatly enhanced our capability to diagnose and treat patients with early stages of atherosclerosis...

Primary cardiac tumors are a rare entity. The presence of a mass in the left atrium suggests myxoma as a first differential diagnosis. Here we present a rare case of a woman with exertional dyspnea with a large tumor in the left atrium. The patient was extensively studied with echocardiography, cardiac MRI, coronary angiography and computed tomography. Extracardiac neoplastic involvement was ruled out. The patient underwent surgery, the mass was removed, and the final diagnosis was an undifferentiated pleomorphic sarcoma...

Background: The aim of this study was to determine if breast arterial calcification (BAC) on mammography predicts myocardial ischemia (MI) on stress myocardial perfusion single-photon emission computed tomography (MPS). BAC is a type of medial artery calcification that can be seen incidentally on mammography, but the relationship between coronary artery calcification and MI on MPS is yet unknown. Methods: A total of 435 consecutive women underwent mammography and stress MPS within 1 year of each other...

Congenital coronary-pulmonary artery fistulas complicated by continuity to a systemic artery and aneurysm are extremely rare. A 78-year-old woman was admitted to our hospital with a complaint of chest discomfort. Coronary angiography showed a coronary aneurysm and coronary-pulmonary artery fistula arising from the left circumflex artery and entering into the right lower pulmonary artery. Computed tomography angiography revealed a left subclavian artery-pulmonary artery fistula communicating with the coronary-pulmonary artery fistula...

BACKGROUND: Postoperative myocardial injury (PMI) is a strong predictor of mortality after noncardiac surgery. PMI is believed to be attributable to coronary artery disease (CAD), yet its etiology is largely unclear. We aimed to quantify the prevalence of significant CAD in patients with and without PMI using coronary computed tomography angiography (CCTA). METHODS: This prospective cohort study included patients of 60 years or older without a history of cardiac disease and with and without PMI after intermediate- to high-risk noncardiac surgery...

BACKGROUND: Previous studies have demonstrated that statin therapy improves cardiac outcomes, probably by stabilizing thin-cap fibroatheroma in patients with coronary artery disease. However, major adverse cardiac events still occur in some patients, despite statin therapy. The aim of this study is to identify clinical predictors for the lack of a favorable vascular response to statin therapy in patients with coronary artery disease. METHODS AND RESULTS: A total of 140 nonculprit plaques from 84 patients with coronary artery disease who were treated with a statin and had serial optical coherence tomography imaging (median interval, 6...

In 2010, the Asian Society of Cardiovascular Imaging (ASCI) provided recommendations for cardiac CT and MRI, and this document reflects an update of the 2010 ASCI appropriate use criteria (AUC). In 2016, the ASCI formed a new working group for revision of AUC for noninvasive cardiac imaging. A major change that we made in this document is the rating of various noninvasive tests (exercise electrocardiogram, echocardiography, positron emission tomography, single-photon emission computed tomography, radionuclide imaging, cardiac magnetic resonance, and cardiac computed tomography/angiography), compared side by side for their applications in various clinical scenarios...

BACKGROUND: Among women aged 50 to 59 years at baseline in the Women's Health Initiative (WHI) Estrogen-Alone (E-Alone) trial, randomization to conjugated equine estrogen-alone versus placebo was associated with lower risk of myocardial infarction and mortality, and, in an ancillary study, the WHI-CACS (WHI Coronary Artery Calcification Study) with lower CAC, measured by cardiac computed tomography ≈8.7 years after baseline randomization. We hypothesized that higher CAC would be related to post-trial coronary heart disease (CHD), cardiovascular disease (CVD), and total mortality, independent of baseline randomization or risk factors...

BACKGROUND: Aortic dissections can present with a broad spectrum of signs and symptoms, making them difficult to diagnose in the emergency department (ED). Aortic dissections can cause occlusion of the coronary arteries, mimicking an acute ST-elevation myocardial infarction (STEMI). Emergency point-of-care ultrasound (POCUS) may be a useful diagnostic tool to help differentiate aortic dissection from a primary myocardial infarction. CASE REPORT: A 69-year-old man with no medical history presented to our ED complaining of chest pain...
