%X Hemostatic system abnormalities have been previously associated with congestive heart failure (CHF). Here, we report a rare case of disseminated intravascular coagulopathy (DIC) in the setting of non-ischemic cardiomyopathy with right atrial and biventricular thrombus. We present a 55-year-old female with a past medical history of bronchial asthma who presented with a six-day history of bilateral leg swelling and dry cough. Her physical examination on admission was significant for signs of biventricular heart failure. Initial workup was significant for elevated pro-brain natriuretic peptide (ProBNP), elevated transaminases, marked thrombocytopenia (19,000/mcL), and coagulopathy with international normalized ratio (INR) of 2.5 and D-dimer of 15,585 ng/mL. Transthoracic echocardiogram (TTE) showed a large mobile right atrial thrombus protruding into the right ventricle and a more adherent left ventricular (LV) thrombus with severely reduced biventricular contractility. Pan CT was done and was significant for multifocal multilobar pulmonary emboli. A lower limb venous duplex was done and revealed extensive bilateral lower limb deep venous thrombosis (DVT). This rare case demonstrates an unusual association between DIC with non-ischemic cardiomyopathy, biventricular thrombus, extensive deep vein thrombosis, and pulmonary embolism (PE). In comparison, there are multiple prior reports for DIC with CHF and LV thrombus. However, our case differs from prior reports in terms of the presence of right atrial and biventricular thrombus. The patient received antibiotics, diuretics, and cryoprecipitate in the setting of persistent low fibrinogen levels. The patient underwent Interventional radiology-guided thrombectomy for extensive pulmonary emboli followed by inferior vena cava (IVC) filter insertion, resulting in the resolution of the right atrial thrombus and extensive decrease of the pulmonary emboli burden. The patient was then given apixaban after normalization of the platelet count and fibrinogen level. Hypercoagulability workup was inconclusive. The patient was then discharged after improvement of symptoms. Early recognition of DIC and cardiac thrombi in patients with new-onset heart failure is crucial for the implementation of the correct management by thrombectomy, optimizing heart failure medications, and anticoagulation to achieve better outcomes.
