    Advance Publication Circulation Journal REVIEW doi: 10.1253/circj.CJ-20-0078 Electrophysiological Procedures in Patients With Coagulation Disorders ― A Systemic Review ― Bartosz Krzowski, MD; Paweł Balsam, MD, PhD; Michał Peller, MD, PhD; Piotr Lodziński, MD, PhD; Marcin Grabowski, MD, PhD; Joanna Drozd-Sokołowska, MD, PhD; Grzegorz Basak, MD, PhD; Monika Gawałko, MD; Grzegorz Opolski, MD, PhD; Jedrzej Kosiuk, MD, PhD Catheter ablation (CA) is considered first-line treatment for many patients with symptomatic arrhythmias. Indications for CA are constantly increasing, as is the number of procedures. Although CA is nowadays regarded a safe procedure, there is a risk of com- plications, including both bleeding- and thrombosis-related events. Several factors contribute to periprocedural risk; of these, patient coagulation status is of considerable clinical relevance. In this context, even a simple procedure poses a considerable challenge in a patient with coagulation disorder. However, the level of evidence regarding CA in patients with coagulation disorders is very low. Neither experts’ recommendations nor clinical guidelines have been presented so far. The aim of this article is to analyze potential procedure-related risks and provide clinicians with useful information and practical suggestions regarding optimization of procedural safety in patients with coagulation disorders. Key Words: Bleeding; Cardiac arrhythmia; Catheter ablation; Coagulation disorders; Thrombosis n recent decades catheter ablation (CA) has become ing CA in patients with coagulation disorders is very low. the treatment of first choice for many patients with The aim of this review was to systematically analyze pos- I symptomatic arrhythmias.

  • Von Willebrand Disease
    Von Willebrand disease Description Von Willebrand disease is a bleeding disorder that slows the blood clotting process, causing prolonged bleeding after an injury. People with this condition often experience easy bruising, long-lasting nosebleeds, and excessive bleeding or oozing following an injury, surgery, or dental work. Mild forms of von Willebrand disease may become apparent only when abnormal bleeding occurs following surgery or a serious injury. Women with this condition typically have heavy or prolonged bleeding during menstruation (menorrhagia), and some may also experience reproductive tract bleeding during pregnancy and childbirth. In severe cases of von Willebrand disease, heavy bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding). Symptoms of von Willebrand disease may change over time. Increased age, pregnancy, exercise, and stress may cause bleeding symptoms to become less frequent. Von Willebrand disease is divided into three types, with type 2 being further divided into four subtypes. Type 1 is the mildest and most common of the three types, accounting for 75 percent of affected individuals. Type 3 is the most severe and rarest form of the condition. The four subtypes of type 2 von Willebrand disease are intermediate in severity. Another form of the disorder, acquired von Willebrand syndrome, is not caused by inherited gene mutations. Acquired von Willebrand syndrome is typically seen along with other disorders, such as diseases that affect bone marrow or immune cell function. This rare form of the condition is characterized by abnormal bleeding into the skin and other soft tissues, usually beginning in adulthood. Frequency Von Willebrand disease is estimated to affect 1 in 100 to 10,000 individuals.

Abstract: Platelets are active key players in haemostasis. Qualitative platelet dysfunctions result in thrombocytopathies variously characterized by defects of their adhesive and procoagulant activation endpoints. In this review, we summarize the traditional platelet defects in adhesion, secretion, and aggregation. In addition, we review the current knowledge about procoagulant platelets, focusing on their role in bleeding or thrombotic pathologies and their pharmaceutical modulation. Procoagulant activity is an important feature of platelet activation, which should be specifically evaluated during the investigation of a suspected thrombocytopathy.

  • Von Willebrand's Disease
    Coagulopathy Case – 5 Andy Nguyen, M.D. 2009 CLINICAL HISTORY PATIENT: 45 year-old woman CLINICAL HISTORY This patient was admitted with massive hemoptysis. At the time of admission, she was receiving Coumadin (sodium warfarin) for superficial thrombophlebitis. The patient’s prothrombin time was 21 seconds, although she had not taken Coumadin since the day preceding admission MEDICAL HISTORY: The patient had an episode of deep vein thrombosis after the birth of her second daughter when she was 30 years old. The patient was placed on heparin, which was then followed by oral anticoagulants for 6 months. After a spontaneous abortion at the age of 32, the patient was placed on oral contraceptives. She subsequently experienced superficial left calf vein thrombophlebitis, and the oral contraceptives were discontinued. Two months prior to this admission, patient developed superficial thrombophlebitis of the legs that were not associated with trauma. Patient was started on Coumadin at that time. FAMILY HISTORY: The paternal grandfather, who died at 32 years of age, had a history of “swollen legs”.
