Total anomalous pulmonary venous connection (TAPVC) is a rare congenital anomaly of the pulmonary veins drainage. In this entity, the pulmonary veins, instead of draining to left atrium, connect abnormally to the systemic venous circulation. A right-to-left shunt is obligatory for survival. Based on its type and degree of pulmonary venous obstruction, TAPVC may result in pulmonary hypertension and congestive heart failure. In severe cases, urgent diagnosis and surgical correction is essential to reduce morbidity and mortality. Echocardiography as the first and safest imaging modality for cardiovascular abnormalities may fail in complete depiction of some complex feature of TAPVC. Computed tomography angiography is then a noninvasive and sensitive choice for mapping the pulmonary veins without the need for invasive cardiac catheterization. Contrast-enhanced MR angiography can be a radiation-free alternative. Authors present a computed tomography-detected supracardiac TAPVC with small patent ductus arteriosus in a 2 months cyanotic infant.

Background Obesity is postulated to be a high-risk factor for thrombosis along with the inherent hypercoagulability of pregnancy. The Confidential Review of Maternal Deaths (CRMD) found that thrombosis was one of the major causes of maternal deaths in Kerala. This study investigates the major risk factor - obesity and its association with thrombosis in our study setting, along with other risk factors.

Background: Atrial fibrillation (AF) has been associated with thoracic radiotherapy, but the specific risk with irradiating different cardiac substructures remains unknown.
Objectives: This study sought to examine the relationship between irradiation of cardiac substructures and the risk of clinically significant (grade ≥3) AF.
Methods: We analyzed data from patients who underwent definitive radiotherapy for localized cancers (non-small cell lung, breast, Hodgkin lymphoma, or esophageal) at our institution between 2004 and 2022.
Early Change in C-Reactive Protein and Venous Thromboembolism in Patients Treated With Immune Checkpoint Inhibitors.

Medical University of Vienna, Department of Medicine I, Division of Hematology and Hemostaseology; Comprehensive Cancer Center Vienna, Vienna, Austria.
Background: Patients with cancer treated with immune-checkpoint inhibitors (ICIs) have a substantial risk of venous thromboembolism (VTE). The association between ICI-induced inflammation and hypercoagulability is unclear, and no biomarkers currently exist to stratify VTE risk.
Objectives: The authors sought to determine the association between the early changes in C-reactive protein (CRP) after ICI initiation and the risk of VTE.

Pulmonary atresia with ventricular septal defect (PA-VSD) is usually diagnosed by transthoracic or fetal echocardiography, with the prenatal diagnosis being feasible and accurate if fetal cardiology services are available. The limitations of transthoracic echocardiography (TTE) in the evaluation of PA-VSD include the complete evaluation of the pulmonary arteries and patent ductus arteriosus, quantitative evaluation of the right ventricle size and function, and delineation of associated cardiac anomalies such as coronary artery anomalies, anomalies of systemic or pulmonary venous return, and complex arch anomalies. Echocardiography also has limitations in evaluating hemodynamics such as flow volumes, shunts, and regurgitant fraction.

Background: COVID-19 is associated with intense systemic inflammation and abnormal coagulation profile leading to an increased incidence of pulmonary embolism (PE). This study investigates whether PE in COVID-19 patients has different clinical, laboratory and radiological characteristics when compared to traditional PE in COVID negative patients.
Methods: We conducted an observational, multicentric, cross-sectional study on consecutive patients diagnosed with PE at admission or during hospital stay from February 21 2019 to February 20 2021.
