Inflammatory Pseudotumor of the Right Ventricle in a 35-Year-Old Woman with Behçet's Disease: A Case Report

Inflammatory pseudotumor is a rare benign neoplasm. It is common in children and has been reported in various locations throughout the body but rarely in the heart. Behçet's disease is a multisystemic, recurrent, inflammatory disorder. We report a 35-year-old Behçet's disease patient with pseudotumor of the right ventricle and multiple pulmonary emboli. Transthoracic echocardiography showed dilation of right atrium, right ventricle, and a mass in the right ventricle. Multislice computed tomography revealed a large, poorly defined mass infiltrating the groove and multiple pulmonary emboli. Surgery was performed with diagnostic and therapeutic intent. Following sternotomy, we identified a mass in the anterior wall of right ventricle, the outflow tract, and the inflow tract of right ventricle. The histopathologic analysis identified an inflammatory infiltrate composed of lymphocytes, plasma cells, and other inflammatory cells, without mitosis. And there were also some thrombus on top of the mass.

Transconduit puncture for catheter ablation of atrial tachycardia in a patient with extracardiac Fontan palliation

Fontan palliation and its variants are the most widely used and accepted approach for regulating pulmonary blood flow and relieving cyanosis in patients with single-ventricle physiology.1 First-generation Fontan procedures involved connection of the right atrium (RA) to the pulmonary artery (PA). However, this frequently caused RA dilation, sluggish RA flow, and atrial fibrosis and was associated with a high incidence of atrial arrhythmias.2,3 Exclusion of most or all of the RA decreases the incidence of atrial arrhythmias; therefore, the Fontan procedure evolved with the establishment of a total cavopulmonary connection by way of either the lateral tunnel (an intra-atrial tunnel) or the extracardiac Fontan.

Descriptive patterns of severe chronic pulmonary hypertension by chest radiography

To find chest roentgenographic (CXR) features to help differentiate two representative diseases with severe chronic pulmonary hypertension (PH). Thirty-six consecutive patients with chronic thromboembolic PH (CTEPH), 38 with primary PH (PPH), and 37 with left heart disease and PH. CXRs were reviewed about 6 features (left 2nd arc protrusion, right descending pulmonary artery diameter (rPAD), cardiothoracic ratio (CTR), right 2nd arc width, avascular area and pleural abnormality). Hemodynamic data and the degree of tricuspid regurgitation (TR) on echocardiography were compared with CXR findings. The diagnostic pattern of CTEPH was the presence of one of two findings, an avascular area or marked rPAD (>20mm) together with pleuritic change. The diagnostic pattern of PPH was one of the two features; without pleuritic abnormality, marked left 2nd arc protrusion (>10mm) or moderate left 2nd arc protrusion (5-10mm) with marked rPAD (<20mm). The sensitivity for the diagnosis of CTEPH among the three diseases was 78% and specificity was 92%. The sensitivity for the diagnosis of PPH was 45% and specificity was 88%. CTR and right 2nd arc width were related to the degree of TR in CTEPH and PPH. Characteristic roentgenographic findings can help differentiate two frequent diseases associated with chronic pulmonary hypertension and reflect the severity of disease.

Pulmonary Embolism as a Consequence of Applying Sequential Compression Device on Legs in a Patient Asymptomatic of Deep Vein Thrombosis

INTRAOPERATIVE pulmonary embolism (PE) is an uncommon complication of emergency intraabdominal surgery. Best practice recommendations for longer surgical cases include the fitting of antithrombotic leg devices such as stockings and pneumatic compression devices. 1,2 Although these devices certainly prevent thrombosis in deep vein thrombosis (DVT)-prone surgical patients, 1,2 we were unable to find reports of any significant complications caused by them (besides minor skin bruising, sores, etc.), namely, dislodgment of a pre-existing thrombus, causing a life-threatening PE. Although PE has been observed after tourniquet deflation in orthopedic surgery cases, 3 we report a case of PE possibly related to pneumatic sequential compression device.
