Abstract:
The Lambl's excrescences(LEs)are elongated valvular fronds with excessive mobility,commonly found at the closure lines of heart valves.These filiform projections are thin and long,exhibiting undulating independent motion.LEs predominantly occur on the ventricular side of the aortic valve and on the atrial side of the mitral valve,although there have been documented cases involving tricuspid,pulmonic,and prosthetic valves.To detect LEs,transesophageal echocardiography is often recommended.The high stress experienced by left-sided valves during closure can lead to tears or lesions in the endocardium that initiate LEs pathogenesis.In this particular case study,we present a patient who presented with acute non-ST-segment elevation myocardial infarction alongside LEs located on the non-coronary cusp of the aortic valve.This specific anatomical location posed significant challenges during percutaneous coronary intervention(PCI),as it required direct contact between the guiding catheter and the aortic valve,thereby increasing the risk of dislodging the LEs.Fortunately,our team successfully performed PCI without encountering any notable complications or embolic events.
