RESUMO
Background: The management of anticoagulation for mechanical heart valves during pregnancy poses a unique challenge. Mechanical valve thrombosis is a devastating complication for which surgery is often the treatment of choice. However, cardiac surgery for prosthetic valve dysfunction in pregnant patients confers a high risk of maternofetal morbidity and mortality. Case summary: A 39-year-old woman in her first pregnancy at 30 weeks gestation presented to hospital with a mechanical mitral valve thrombosis despite therapeutic anticoagulation with low-molecular-weight heparin. She underwent an emergent caesarean section followed immediately by a bioprosthetic mitral valve replacement. This occurred after careful planning and organization on the part of a large multidisciplinary team. Discussion: A proactive, rather than reactive, approach to the surgical management of a mechanical valve thrombosis in pregnancy will maximize the chances of successful maternal and fetal outcomes.
RESUMO
This case report describes an initially stabilized transcatheter heart valve that embolized in the ascending aorta, leading to a postprocedural acute type A aortic dissection.

Pump thrombosis can occur in patients with a left ventricular assist device (LVAD). It can be treated medically with thrombolytic agents or surgically. We present a case of a man who successfully underwent an LVAD swap via left anterior thoracotomy due to recurrent thromboses in the inflow cannula.
