Abstract:

Although in the last decade transcatheter valves emerged as a new alternative in high risk patients, surgical valve replacement remains the gold standard for treatment of valvular heart disease in patients with low to intermediate surgical risk. Mechanic heart valve thrombosis is one of the most serious and deadly complications in patients submitted to valve replacement. Patients can be asymptomatic or present with severe heart failure and cardiogenic shock. Urgent surgery or fibrinolysis is currently the only options available when approaching symptomatic patients. However, there is scarce information regarding asymptomatic persistent disc obstruction after fibrinolytic therapy. We report a case of a young woman presenting with heart failure symptoms due to mechanic mitral valve thrombosis occurring after pregnancy with suboptimal anticoagulation. After fibrinolysis, symptomatic relief and hemodynamic stability were obtained, maintaining, however, valve disc obstruction. Adding antiplatelet therapy could be a viable option.
