ABSTRACT
A primary cardiac angiosarcoma is a rare type of soft-tissue sarcoma with a high mortality rate. This report describes a young woman who presented with chest pain and worsening shortness of breath over the course of a year. She was diagnosed with and treated for latent tuberculosis and autoimmune pericarditis over the last year, however, her condition kept worsening. Further workup revealed a large pericardial and right atrial mass associated with multiple lung nodules. The biopsy from the lung mass showed angiosarcoma, and she was diagnosed with primary metastatic angiosarcoma of the pericardium. She was treated with doxorubicin and Ifosfamide (AIM-75 regimen), which led to a partial response. However, soon after completion of six cycles, the tumour progressed rapidly, leading to cardio-respiratory failure. In this report, we will discuss the clinical challenges and treatment options (surgical and medical) that are available for treating patients with angiosarcoma of the heart.

Risk factors for pediatric cerebral sinovenous thrombosis: A case-control study with case validation
Sellers A, et al. Thromb Res 2020.
ABSTRACT
INTRODUCTION: Cerebral sinovenous thrombosis (CSVT) represents the second most common type of venous thromboembolism (VTE) in children. Current literature includes limited evidence on risk factors for CSVT, particularly in the pediatric population. We sought to determine risk factors for CSVT in pediatric patients through a single-institutional case-control study. In addition, we evaluated thrombophilias, treatments and outcomes in CSVT among cases.
METHODS: A case-control study was performed at Johns Hopkins All Children's Hospital on patients admitted from March 31, 2006 through April 1, 2018. Cases were identified using diagnostic codes and confirmed based on electronic health record (EHR) and neuroimaging review. Controls were matched in a 2:1 fashion accounting for the month and year of admission.
RESULTS: A total of 60 CSVT cases and 120 controls were identified. Median (range) age was 4.8 years (0-21.3 years) for cases and 5.6 years (0-20.0 years) for controls. Factors putatively associated with CSVT in unadjusted analyses were: corticosteroid use, presence of a central venous catheter, mechanical ventilation, systemic infection, head/neck infection, head/neck trauma, and chronic inflammatory disease. In the multivariable model, head/neck infection (OR: 13.8, 95% CI: 4.87-38.7; P < 0.01), head/neck trauma (OR: 12.7, 95% CI: 2.88-56.2; P < 0.01), and mechanical ventilation (OR: 9.32, 95% CI: 2.35-36.9; P = 0.01) remained independent, statistically-significant risk factors. 61% of patients were subacutely treated with anticoagulants and of those, only two developed relevant bleeding after initiation of therapy.
CONCLUSIONS: This single-institutional case-control study reveals that head/neck infection, head/neck trauma, and mechanical ventilation are independent risk factors for pediatric CSVT. These findings will be further investigated via a cooperative registry of pediatric hospital-acquired VTE, by which a risk model for pediatric CSVT will be developed and validated, in order to inform future preventive strategies in at-risk pediatric patients.

Quality Improvement at an Academic Cancer Center: Venous Thromboembolism Prophylaxis in Patients With Multiple Myeloma
Baz R, et al. Cancer Control 2020.
ABSTRACT
Patients with multiple myeloma are at elevated risk of venous thromboembolism (VTE), the second leading cause of death in patients with cancer, but physician adherence to VTE prevention guidelines is low. Several organizations partnered in designing and implementing a 2-year quality improvement (QI) program in a tertiary care/academic cancer center, to increase awareness of VTE prophylaxis for patients with multiple myeloma and thus improve adherence to prophylaxis guidelines and protocols. The QI arm included 2 chart audits, conducted 2 years apart, of unmatched cohorts of 100 patients with multiple myeloma. An Education arm included 2 grand rounds presentations, 3 web-based case discussions, and a patient education module. Twenty providers took part in the continuous QI arm. More than 1100 learners participated in the online cases; the patient education curriculum reached 112 multiple myeloma patients. The initiative proved helpful in defining barriers to guideline adherence and identifying data-driven practice improvement strategies for VTE prophylaxis. It also increased learner awareness of VTE guidelines, patient risk stratification, and optimal thromboprophylaxis strategies. There was a reduction in VTE events (primary clinical outcome) from 10% at baseline to 4% in the follow-up cohort, although this was not statistically significant. Higher rates of guideline-based prophylaxis were observed in low-risk patients, and a lower incidence of VTE was observed in multiple myeloma patients with a prior history of VTE. Additional research is needed to refine prophylaxis guidelines. With appropriate institutional support, this type of QI program can be readily adopted by other organizations to address practice improvement needs.

Dissolution of metastatic thymic carcinoma-associated right atrial thrombus with rivaroxaban
Nimblette C, et al. SAGE Open Med Case Rep 2020.
ABSTRACT
Thymic carcinoma typically exhibits more clinically aggressive behavior and portends a worse prognosis as compared to thymoma. Venous thromboembolism is a significant cause of morbidity and mortality in oncologic patients. Traditionally, the standard-of-care management of cancer-associated venous thromboembolism has been therapeutic anticoagulation with low molecular weight heparins; however, with the advent of direct oral anticoagulants, there is an ongoing paradigm shift to transition to these novel agents in an attempt to attenuate cancer-associated venous thromboembolism events. We describe an exceedingly rare case of metastatic thymic carcinoma-associated right atrial thrombus with high-risk embolic features, which subsequently underwent near-complete dissolution with rivaroxaban after 3 months.

Vascular Damage - Coronary Artery Disease
Cadeddu Dessalvi C, et al. J Cardiovasc Echogr 2020 - Review.
ABSTRACT
Cardiovascular complications during chemotherapy and radiotherapy are becoming an increasing problem because many patients with cancer are treated with agents that exert significant vascular toxicity. Coronary heart disease in patients with cancer presents particular challenges, which directly impact the management of both the coronary disease and malignancy. Several chemotherapeutic agents have been shown to trigger ischemic heart disease, and as it has happened for myocardial cardiotoxicity, more attention should be dedicated to improving early recognition and prevention of cardiac vascular toxicity. Cardiac imaging could facilitate early detection of vascular toxicity, but a thorough risk stratification should always be performed to identify patients at higher risk of vascular impairment.

INSPIRE: A European training network to Foster research and training in cardiovascular safety pharmacology
Guns PD, et al. J Pharmacol Toxicol Methods 2020.
ABSTRACT
Safety pharmacology is an essential part of drug development aiming to identify, evaluate and investigate undesirable pharmacodynamic properties of a drug primarily prior to clinical trials. In particular, cardiovascular adverse drug reactions (ADR) have halted many drug development programs. Safety pharmacology has successfully implemented a screening strategy to detect cardiovascular liabilities, but there is room for further refinement. In this setting, we present the INSPIRE project, a European Training Network in safety pharmacology for Early Stage Researchers (ESRs), funded by the European Commission's H2020-MSCA-ITN programme. INSPIRE has recruited 15 ESR fellows that will conduct an individual PhD-research project for a period of 36 months. INSPIRE aims to be complementary to ongoing research initiatives. With this as a goal, an inventory of collaborative research initiatives in safety pharmacology was created and the ESR projects have been designed to be complementary to this roadmap. Overall, INSPIRE aims to improve cardiovascular safety evaluation, either by investigating technological innovations or by adding mechanistic insight in emerging safety concerns, as observed in the field of cardio-oncology. Finally, in addition to its hands-on research pillar, INSPIRE will organize a number of summer schools and workshops that will be open to the wider community as well. In summary, INSPIRE aims to foster both research and training in safety pharmacology and hopes to inspire the future generation of safety scientists.
