Thrombosis on a heart valve without any accompanying
cardiac or vascular pathology in coagulation disorders is
a rare occasion. A 43-year-old female patient who was
under follow-up for deep vein thrombosis was admitted
to our clinic with dyspnea. On echocardiography, a freefloating
thrombus of 70 to 80 mm in size attached to the
non-coronary sinus of the aorta via a pedicle was detected.
Fibrinolytic therapy was not performed due to its poor
prognosis of possible complications. The thrombus was
removed under cardiopulmonary bypass. Neither a pathology
nor an additional thrombus was detected on the valve and
within the heart. No postoperative complication was observed.
Histopathological examination result was reported as a nonbacterial
thrombus. Life-long warfarin sodium treatment was
prescribed for recurrent thromboembolism. In this article, we
describe the type and duration of the treatment, and follow-up
of hereditary coagulation disorders and thromboembolism in
other family members in the light of literature data.
