With the development of next-generation sequencing (NGS) technologies it became possible to simultaneously analyze millions variants. Despite quality improvement, is generally still required confirm variants before reporting. However, in recent years dominant idea that one could define thresholds for "high quality" which do not require orthogonal validation. that, no works date report concordance between from whole genome and their gold-standard Sanger In this study we analyzed 1756 WGS...

Background ― Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare life-threatening form of artery hypertension. CTEPH potentially curable by performing surgical operation – thrombendarteriectomy. Unfortunately, about 36% patients with are considered as inoperable because different conditions including left main coronary compression syndrome (LMCS), caused delated artery. Appropriate management and LMCS remains unknown. Case report We for the first time case successful hybrid...
