Cardiac involvement in cancer is increasingly important in the diagnosis and follow-up of patients. A thorough cardiovascular evaluation using multimodal imaging is crucial to assess any direct cardiac involvement from oncological disease progression and to determine the cardiovascular risk of patients undergoing oncological therapies. Early detection of cardiac dysfunction, particularly due to cardiotoxicity from chemotherapy or radiotherapy, is essential to establish the disease’s overall prognostic impact. Comprehensive cardiovascular imaging should be integral to the clinical management of cancer patients. Echocardiography remains highly effective for assessing cardiac function, including systolic performance and ventricular filling pressures, with speckle-tracking echocardiography offering early insights into chemotoxicity-related myocardial damage. Cardiac computed tomography (CT) provides precise anatomical detail, especially for cardiac involvement due to metastasis or adjacent mediastinal or lung tumors. Coronary assessment is also important for initial risk stratification and monitoring potential coronary artery disease progression after radiotherapy or chemotherapeutic treatment. Finally, cardiac magnetic resonance (CMR) is the gold standard for myocardial tissue characterization, aiding in the differential diagnosis of cardiac masses. CMR’s mapping techniques allow for early detection of myocardial inflammation caused by cardiotoxicity. This review explores the applicability of echocardiography, cardiac CT, and CMR in cancer patients with extracardiac tumors.

Carcinoid heart disease (CHD) affects right-sided valves and causes significant mortality and morbidity. Even though the pathophysiology of the disease is not entirely understood, it is known that chronic exposure to high levels of circulating serotonin is the main factor responsible for developing valvular heart disease. Cardiac imaging plays a critical role in the management of CHD, so the final diagnosis can be performed through multimodal imaging techniques and the measurement of biomarkers. Moreover, in observational studies, surgical treatment of carcinoid-induced valve disease has been found to improve outcomes. Despite advancements in pre-operative preparation in recent years, mortality rates remain high in elderly patients and those with multiple comorbidities due to the risk of intra-operative carcinoid crisis and high post-operative bleeding. In this comprehensive review, we will analyze the causes of carcinoid syndrome and how it can result in severe right heart failure. The role of different imaging modalities in detecting heart valve disease will be discussed together with the therapeutic options at our disposal, such as medical treatment, surgery, and the novel role of transcatheter intervention.

Background/Objectives: Extracorporeal membrane oxygenation (ECMO) has been widely used as a life support technique in COVID-19 acute respiratory distress syndrome (ARDS). The use of anticoagulation during ECMO support remains a topic of debate. The primary aim of this study is to demonstrate the safety and efficacy of using argatroban as an anticoagulant instead of heparin in patients with heparin-associated thrombocytopenia. Methods: 40 patients were enrolled and initially treated with unfractionated heparin for anticoagulation during ECMO, composing the UFH group. Twenty-one of these patients experienced a drop in platelet count to below 100,000 cells/mm³ and, after testing negative for IgG anti-PF4/heparin, the anticoagulation was switched to argatroban, composing the ARG group. Hemorrhagic events were recorded along with blood chemistry parameters. Results: Bleedings were significantly more frequent in the UFH group than in ARG group (58/579 days vs. 21/357 days, p = 0.041). No significant differences were observed in hemorrhagic episodes for each bleeding site, except for tracheal stoma (14 vs. 1, p = 0.011). No differences in activated partial thromboplastin time (aPTT) values were found between the two groups (aPTT 42.65 s vs. 44.70 s, p = 0.443). Linear regression analysis revealed that the platelet count on day 5 was correlated with the initial platelet count but not with the type of anticoagulant used (p = 0.001, CI 0.55, 0.69 and p = 0.078). Linear regression analysis in both groups showed a correlation between the duration of ECMO support and intensive care unit stay for the median aPTT and median platelet count. Furthermore, no major systemic thrombotic events or circuit clotting were observed in this patient cohort. Conclusions: Argatroban seems to be safe in patients with persistent heparin-associated thrombocytopenia undergoing ECMO.
