BACKGROUND: Congenital coronary anomalies (CCAs) and coronary artery disease (CAD) arouse intense scientific and clinical interest in sports medicine and sports cardiology medical communities because of their potential to trigger sudden cardiac death (SCD) in athletes. Exercise stress testing represent the first instrumental assessment to evaluate electrocardiographic changes during effort. Coronary computed tomography angiography (CCTA) is an advanced accurate noninvasive imaging modality for excluding CAD and abnormalities of origin and course of coronary vessels...

REVIEW
George Galyfos, Fragiska Sigala, Konstantinos Filis
Transradial (TR) access has been extensively compared to transfemoral (TF) access in patients undergoing percutaneous coronary interventions, with TR method showing a clear benefit over the latter. However, comparative data concerning peripheral artery endovascular interventions has been limited in the literature. Therefore, a systematic review was conducted in order to compare main outcomes between TR and TF access in patients undergoing peripheral artery angioplasty and/or stenting. Main outcomes included technical success, major/minor bleeding risk, access site complications, hospital stay, death, myocardial infarction, neurological events and other procedural parameters...

BACKGROUND: Transthoracic echocardiography (TTE) has been used to assess coronary sinus blood flow (CSBF), which reflects total coronary arterial blood flow. Successful angioplasty is expected to improve coronary arterial blood flow. Changes in CSBF after percutaneous coronary intervention (PCI), as assessed by TTE, have not been systematically evaluated. HYPOTHESIS: TTE can be utilized to reflect increased CSBF after a successful, clinically indicated PCI. METHODS: The study cohort included 31 patients (18 females, 62 ± 11 years old) referred for diagnostic cardiac catheterization for suspected coronary artery disease and possible PCI, when clinically indicated...

Traumatic external iliac artery dissection after renal transplant is a rare complication, but it should be urgently managed due to its devastating effects on graft and lower limb circulation. External iliac artery dissection is seen more in recipients with diabetes mellitus and comorbid disease. Recipients with external iliac artery dissection should be treated immediately by percutaneus angioplasty or surgical reconstruction. In this study, we reported the management of 2 kidney transplant cases with external iliac artery dissection due to vascular clamping of the artery...

Iliac artery occlusive disease can present as a sudden-onset acute thrombotic or thromboembolic event or as a chronic progressive atherosclerotic process that presents as claudication progressing to rest pain. Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease...

More recent immune thrombocytopenia (ITP) treatment strategies enhance platelet production with the use of thrombopoietin receptor agonists (TPO-RA) such as eltrombopag. Patients receiving TPO-RA agents may be at an increased risk of thromboembolism, however the pathophysiology and common underlying risk factors are not well understood. We present the case of a young asplenic woman on eltrombopag for chronic ITP with acute myocardial infarction involving the right coronary artery. Past medical history was significant for remote mediastinal radiation for lymphoma and splenectomy for ITP...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an alternative therapy for patients with chronic thromboembolic pulmonary hypertension who are ineligible for pulmonary endarterectomy-the standard therapy. Currently, most reported results of BPA are from relatively small cohorts treated at single centers. The present study evaluated the safety and efficacy of BPA for chronic thromboembolic pulmonary hypertension based on a multicenter registry. METHODS AND RESULTS: A total of 308 patients (62 men and 246 women; mean age, 61 years) underwent 1408 procedures at 7 institutions in Japan...

The phenotypic switch of vascular smooth muscle cells (VSMCs) is a key event in the pathogenesis of various vascular diseases, such as atherosclerosis and post-angioplasty restenosis. Small non-coding microRNAs (miRNAs) have emerged as critical modulators of VSMC function. In the present study, miR-26a was significantly increased in cultured VSMCs stimulated by platelet-derived growth factor-BB (PDGF-BB) and in arteries with neointimal lesion formation. Moreover, we demonstrated that miR-26a regulates the expression of VSMC differentiation marker genes such as α-smooth muscle actin (α-SMA), calponin and smooth muscle myosin heavy chain (SM-MHC) in PDGF-BB-treated VSMCs...
