ABSTRACT
INTRODUCTION: Rotation thromboelastometry (ROTEM®) can be used for hypercoagulability evaluation. Cushing's syndrome (CS) is associated with hypercoagulability; however, ROTEM® has never been evaluated in this setting. OBJECTIVE: To evaluate hypercoagulability in CS using ROTEM® and to correlate these parameters with coagulation markers and with the presence of deep vein thrombosis. DESIGN AND METHODS: Thirty patients with active CS (26 women) and 30 controls matched for age, sex, body mass index, diabetes mellitus, arterial hypertension, ABO blood group and smoking were included. We measured levels of activated partial thromboplastin time (aPTT), platelets, fibrinogen, D-dimer, factor VIII (FVIII), von Willebrand factor (vWF) and C-reactive protein. ROTEM® was used to evaluate the intrinsic (INTEM), extrinsic (EXTEM) and fibrinogen (FIBTEM) pathways. Doppler ultrasonography was performed to search for lower limbs deep vein thrombosis. RESULTS: INTEM clotting time using ROTEM® was shorter in patients than in controls (P = 0·04). Other ROTEM® parameters were not different. Mean aPTT was shorter in patients than in controls (P = 0·001). The FVIII, vWF and D-dimer levels were higher in patients than in controls (P = 0·001, 0·001 and 0·02, respectively). Obese CS patients presented higher levels of platelets and alterations in maximum clot formation (MCF), alpha angle and maximum speed of clot formation of INTEM (P = 0·03, 0·02 and 0·02, respectively) and an increase in the MCF of FIBTEM (P = 0·02). No deep vein thrombosis was found. CONCLUSIONS: Although FVIII and vWF were abnormal in CS patients, only the initiation clot formation was different in the ROTEM® methodology and no deep vein thrombosis was found.

Cor triatriatum (CT) is a rare congenital cardiac anomaly that usually becomes symptomatic in the first years of life. If the condition is not associated with other cardiac defects, and depending on the degree of communication between the upper chamber and left atrium (LA), patients may reach adulthood. We report a case of an asymptomatic, adult, female patient with CT diagnosed by transthoracic echocardiogram (TTE) and followed-up during pregnancy.

Cor triatriatum (CT) é uma cardiopatia congênita rara que geralmente cursa com sintomas nos primeiros anos de vida. Na ausência de outras malformações cardíacas associadas e na dependência do grau de comunicação entre a câmara superior e o átrio esquerdo (AE), os pacientes podem atingir a idade adulta. Relatamos um caso de uma paciente adulta assintomática portadora de CT diagnosticado pelo ecocardiograma transtorácico (ETT) e acompanhada clinicamente durante a gestação.
