Congenital hypodysfibrinogenemia associated with a novel deletion of three residues (γAla289_Asp291del) in fibrinogen.
Hypodysfibrinogenemia is the least frequently reported congenital fibrinogen disorder, characterized by both quantity and quality defects of fibrinogen. In this study, we investigated the molecular basis of hypodysfibrinogenemia in a Chinese family. Functional fibrinogen was measured by Clauss method, and the antigenic fibrinogen was measured by immunoturbidimetry assay. ⋯ While the clot lysis showed normal. Scanning electron microscopy revealed that the fibers of the propositus were thicker than normal, with larger pores and curlier meshworks. We conclude that γAla289_Asp291del is responsible for the hypodysfibrinogenemia in this case.

A pulmonary embolism response team (PERT) approach: initial experience from the Cleveland Clinic.
Management of intermediate and high risk acute pulmonary embolism (PE) is challenging. The role of multidisciplinary teams for the care of these patients is emerging. Herein, we report our experience with a pulmonary embolism response team (PERT). ⋯ There were no bleeding events among patients who received systemic low dose or full dose rtPA. A multidisciplinary approach to cases of intermediate risk and high risk PE can be implemented successfully. We saw a relatively low rate of bleeding events with use of rtPA.

Cangrelor use prior to left ventricular assist device surgery: a case series.
Bleeding frequently occurs in patients undergoing placement of a left ventricular assist device (LVAD). Clinical factors that have been identified as contributing to peri-procedural bleeding include LVAD implantation after an acute myocardial infarction and preoperative use of antiplatelet agents. In this report, we describe the use of cangrelor for preoperative antiplatelet bridging to LVAD in five post myocardial infarction patients with cardiogenic shock that had recently undergone percutaneous coronary intervention. ⋯ During the first week following LVAD implantation, two patients experienced a major bleeding (each case required chest exploration for suspected hemorrhage). To our knowledge, this is the first series describing cangrelor use for antiplatelet bridging in patients undergoing LVAD implantation. While this series suggest cangrelor could possibly be a safe and effective antiplatelet bridging strategy, further research is needed to identify the optimal antithrombotic strategy in cardiogenic shock patients undergoing LVAD implantation who have recently undergoing percutaneous coronary intervention.
