lambl excrescences definition
Lambl's excrescences are filiform fronds that occur at sites of valve closure. They originate as small thrombi on endocardial surfaces (where the valve margins contact) and have the potential to embolize to distant organs. We describe the case of a 61-year-old woman who presented with repeated episodes of stroke. She was found to have Lambl's excrescences on all 3 leaflets of the aortic valve. After all other possible causes of stroke were ruled out, she underwent successful open heart surgery for debridement dÃ©bridement of these. excrescences
