Acute oxygenator occlusion in two cases of polycythemia vera: Bailout strategies

Polycytemia vera (PV) is a rare myeloproliferative neoplasm associated with microcirculatory disturbances, thrombosis and bleeding. Patients suffering from PV have a high risk of perioperative adverse events, but the literature regarding on-pump procedures in PV patients is scarce. We report two cases of acute and severe oxygenator failure during cardiopulmonary bypass and present valid exit scenarios.     

The impact of COVID-19 on the provision of cardiac surgical services

The global pandemic caused by COVID-19 has had a significant global impact on healthcare systems. One implication of this pandemic is the cancellation of elective cardiac surgeries and the centralization of services. As a result, hospitals in Europe, North America, and the United Kingdom have had to alter the services offered to patients to be able to cope with service provision for COVID infected patients. Data should be collected during this period to provide a good insight following the lockdown period to understand the implication of such service alteration. Future research should also focus on the effects on long-term mortality and morbidity as well as financial implications on hospitals as a result of these changes.     

Congenital left ventricular diverticulum repair in an adult with dual patch technique

Rupture of a congenital left ventricular diverticulum (CLVD), a rare anatomical anomaly, is a catastrophic event, with potential fatal consequences. Repair techniques documented in the literature include primary closure and single patch closure. We describe a case of a 57-year-old woman with symptomatic anterolateral CLVD. Our approach involves a linear incision through the epicardial surface of the diverticulum with exclusion of the cavity, and restoration of normal ventricular geometry via a two-patch technique.
