Pathological anatomy of pulmonary vascular lesions plays a key role in understanding the patho-genesis and morphogenesis COVID-19. This review focuses on morphological features injury The virus is known to be capable causing not only cytopathic cell damage various organs tissues (type II pneumocytes, cardiomyocytes, neurons, epithelial cells gas-trointestinal tract) but also endotheliotropic th...

INTRODUCTION The purpose of this study was to perform a quantitative fluoroscopic analysis of the coronary sinus ostium and its relationship to the His bundle in patients with and without AV nodal reentrant tachycardia. Sites of slow pathway ablation are often near the coronary sinus ostium, which can be located within a few millimeters of the His bundle. Whether such close proximity of the cor...

OBJECTIVES To determine if coronary computed tomographic angiography enhances prediction of perioperative risk in patients before non-cardiac surgery and to assess the preoperative coronary anatomy in patients who experience a myocardial infarction after non-cardiac surgery. DESIGN Prospective cohort study. SETTING 12 centers in eight countries. PARTICIPANTS 955 patients with, or at risk ...

We report a rare case of atrial tachycardia originating from the non-coronary aortic sinus. After failed radiofrequency (RF) energy applications at right His-bundle region, the complete elimination of atrial tachycardia was achieved with an RF energy application in the non-coronary aortic sinus. With the review of other papers, this report emphasizes the importance of mapping in the non-coronar...

Direct effects of adrenergic stimuli on coronary vessels in dogs were compared with effects on vessels to skin (hind paw) and skeletal muscle (gracilis muscle) after intravenous administration of practolol (2 mg/kg), a selective myocardial beta receptor blocker which minimized indirect effects of myocardial stimulation on coronary vascular resistance. The left circumflex coronary, cranial tibia...

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, ho...

Aim. To describe new data and to complement the existing information about anatomic features of hepatic vein structure in donor right lobe, formulate principles selection proceeding from vascular anatomy. Materials methods. 306 liver transplantations living related donors were performed at A.I. Burnazyan Federal Medical Biophysical Center Biological Agency Russia 2009 2021. The anatomy 518 pote...

Myocardial bridging is recognized as an anatomical variation of the human coronary circulation in which an epicardial artery lies in the myocardium for part of its course. Thus, the vessel is ‘bridged’ by myocardium. The present study is aimed to studying presence of myocardial bridges over coronary arteries and their branches by dissection method. A total of 50 adult human hearts (irrespective...
