Lambl's excrescences are filamentous extensions of cardiac valves, mostly asymptomatic but rarely associated with catastrophic thromboembolic events such as acute ischemic stroke and acute coronary syndromes. Numerous case reports cited in the literature have addressed various spectrum of presentation of these syndromes and their outcomes based on therapies used. We encountered such a patient from our own experience who presented with an acute ischemic stroke with no other identifiable cause other than the Lambl's excrescences. We subsequently carried out an extensive literature search and based on our interpretation of the outcomes we decided to treat the patient to the best of our understanding. In the proceeding section we describe the case and the discussion and our rationale to treat the patient accordingly.
