Conclusion:
The incidence of THV thrombosis after TMVR remains largely unknown.
Until unless systemic echocardiographic follow-up is not performed, this
complication may remain undiagnosed.
Mild raised trans mitral gradients on trans thoracic gradients usually
overlook the post TMVR thrombus that’s why systemic TEE may be necessary
during follow-up of these patients and must be mandatory in patients
with elevated trans mitral gradients.
Early or late subclinical prosthetic valve thrombosis may occur
frequently after TMVR, and long-term anticoagulant therapy may therefore
be necessary in combination with antiplatelet therapy despite the
increased bleeding risk.
