BACKGROUND: Transthyretin (TTR) is the transporter protein (55 kDA) that carries retinol binding protein and thyroxin (T4) in its functional tetramer form. Presence of mutation in this protein (TTR) may lead to the dissociation of tetramers to monomer which unfolds and self associates to form amyloid aggregates. Aggregation of this protein has been found to be associated with various life threatening disorders such as coronary artery disease (CAD) which is the major cause of mortality and morbidity worldwide...

A 56-year-old man with no previous medical history collapsed and was not able to be resuscitated. The major findings at autopsy were enlargement of the heart (weight = 527 g) which contained an infiltrating firm, homogeneous tumor in an epicardial location adjacent to the left anterior descending and right coronary arteries, with further extension into the right ventricular outflow tract, the interventricular septum and left ventricular free wall. Sections showed sheets of small lymphoid cells with scattered large lymphocytes amounting to a low-grade follicular non-Hodgkin lymphoma, as tumor cells were CD20, CD10, Bcl 2 and LMO 2 positive...

Coronary computed tomography angiography (CCTA) can provide abundant information about the anatomy of the coronary artery. However, this modality is limited in evaluation of myocardial function. Four-dimensional speckle tracking echocardiography (4DSTE) is a novel and sensitive technique for quantitative evaluation of myocardial deformation. We estimated the value of these imaging modalities to predict the risk of MACE in 209 patients with suspected coronary artery disease(CAD) after a median follow-up of 727 days...

Background: A growing population of young adults is presenting to cardiologists with late manifestations of Kawasaki disease (KD) that include cardiomyopathy, ischemia, and infarction. The management of these conditions differs in important ways from atherosclerotic heart disease, and yet there is little awareness in the adult cardiology community regarding the special challenges posed by the cardiovascular sequelae of KD. Methods: Observations were made on a population of 140 adult KD patients enrolled in the San Diego Adult KD Collaborative Study...

Kawasaki disease (KD) is an acute idiopathic vasculitis affecting infants and children. Coronary artery abnormalities and myocarditis are the major cardiovascular complications of KD. Coronary artery abnormalities develop in 15-25% of untreated KD. Two-dimensional transthoracic echocardiography has hitherto been considered the modality of choice for evaluation of children with KD. There are, however, several limitations inherent to echocardiography - including limited evaluation of distal vessels, left circumflex artery and poor acoustic window in growing children...

Background: Echocardiographic features of acute Kawasaki disease (KD) have not been well characterized in Egyptian children. This study aimed to provide insight into the pattern of cardiac involvement in Egyptian children with Kawasaki disease, focusing on echocardiographic coronary abnormalities and their associated risk predictors. Methods and Results: Medical records of 64 KD patients from 2012 to 2016 were retrospectively analyzed with recalculation of coronary artery z-scores during the first eight weeks after fever onset...

Aneurysmal coronary artery disease (ACAD) comprises both coronary artery aneurysms (CAA) and coronary artery ectasia (CAE). The reported prevalence of ACAD varies widely from 0.2 to 10%, with male predominance and a predilection for the right coronary artery (RCA). Atherosclerosis is the commonest cause of ACAD in adults, while Kawasaki disease is the commonest cause in children and adolescents, as well as in the Far East. Most patients are asymptomatic, but when symptoms do exist, they are usually related to myocardial ischemia...

Kawasaki disease is an acute vasculitis of early childhood. Its incidence varies among different ethnic groups with higher rates among Asians. In this case series, we presented four cases of Kawasaki disease with incomplete or atypical presentations in Egyptian children. Two cases presented with meningitis, which is not a criteria for the diagnosis of Kawasaki disease. The other two cases presented with pharyngitis and fever, which did not respond to antibiotics. The clinical criteria for diagnosis of Kawasaki disease were either incomplete or appeared sequentially...

Background: Awareness of Kawasaki disease (KD) is emerging in Russia but the diagnosis is still often missed. Methods: This is a retrospective study of 303 children with KD who received care at a single center in Moscow over the period from 2004 to 2016. Results: Overall, coronary artery aneurysms were documented in 91 (30,0%) of 303 patients and transient ectasia in 40 (13,2%). Intracoronary thrombi were found in 12 of 15 patients with giant aneurysms and in 3 patients with medium-sized aneurysms. Conclusion: The patients with KD in the Moscow region had typical features of the disease described in the literature but the proportion of patients with coronary artery aneurysms was higher than reported from other countries...

Kawasaki disease (KD) is one of the most common childhood vasculitides and may lead to coronary arterial complications. KD has been reported in more than 60 countries over five continents. Previous publications have provided a comprehensive description of the epidemiologic features of KD including incidence, age of onset, seasonal trends, and rates of cardiac lesions. However, the interactions among the KD patients, time (seasons) and place have been less well studied. We review the current global epidemiology of KD and focus on the longitudinal changes in incidence, seasonality and response to intravenous immunoglobulin (IVIG) therapy...

Background: The purpose of this paper is to provide technology trends and information regarding market and prospects in stents used for human blood vessels in Korea and the world.A stent is a medical device in the form of a cylindrical metal net used to normalize flow when blood or other bodily fluids such as biliary fluids are obstructed in blood vessels, gastrointestinal tracts, etc. by inserting the stent into a narrowed or clogged area. Stents are classified into vascular and non-vascular stents...

We report a case of Tangier disease with Leriche syndrome and bleeding tendency. In this male patient, nasal hemorrhage had been observed frequently throughout childhood. At 46 years old, he experienced effort angina, and coronary angiography demonstrated 75% stenosis in the right coronary artery. Orange-colored tonsils, mild hepatosplenomegaly and very low levels of serum high-density lipoprotein cholesterol (HDL-C) were observed, and the patient was diagnosed with Tangier disease. At 52 years old, effort angina recurred...

Percutaneous coronary intervention (PCI) has emerged as an alternative treatment to coronary artery bypass grafting (CABG) in patients with unprotected left main coronary artery disease (ULMCAD). However, the optimal treatment for ULMCAD concomitant with chronic kidney disease (CKD) was rarely addressed. Herein, we compare the long-term outcomes of these patients treated with CABG or PCI.From January 2004 to December 2010, 185 patients with ULMCAD and CKD undergoing PCI (n = 84) or CABG (n = 101) were matched for the selection criteria...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and little is known about characteristics, treatment, and follow-up of patients with SCAD. Computed tomography angiography (CTA) plays an important role in the diagnosis and management of SCAD. Herein, we describe a case of a patient with SCAD who underwent successful conservative management, and in whom CTA was able to detect rapid healing of the dissection, 4.5 hours post-dissection.

BACKGROUND: Compared with global cardiac adiposity, the local accumulation of fat surrounding coronary arteries might have a more direct impact on coronary artery disease (CAD). Here, we compared the local epicardial adipose tissue (EAT) thickness and global cardiac adiposity volumes for predicting CAD.Methods and Results:A total of 197 consecutive subjects underwent 320-slice multi-detector computed tomography coronary angiography and were segregated into CAD (≥1 coronary artery branch stenosis ≥50%) and non-CAD groups...
