A Rare Case of Coronary Stent Thrombosis in the Modern Era.

In patients with acute coronary syndrome or obstructive coronary artery disease, stents, especially drug-eluting stents (DESs), are used for percutaneous coronary interventions (PCI). DES prevents abrupt closure of the stented artery. Stent thrombosis is an uncommon but serious complication of PCI, especially with the recent advancement of stent technology. We present a case of a 75-year-old male who initially suffered a non-ST segment elevation myocardial infarction (NSTEMI) treated appropriately with PCI and subsequently developed stent thrombosis after 10 days of initial stent placement. He then underwent emergent repeat PCI with successful replacement of stents overlapping previous stents. The patient did well following the procedure. His clopidogrel was changed to a more potent antiplatelet ticagrelor. He remained stable throughout the hospital stay and was discharged home without any further complications following the next 90 days.

Transient Ischemic Attack Secondary to Device-Related Thrombus After Left Atrial Appendage Closure.

The patient is an 84-year-old female with a significant past medical history of traumatic subarachnoid hemorrhage, bleeding peptic ulcer disease, permanent atrial fibrillation status post percutaneous left atrial appendage closure (LAAC) initially admitted to the hospital secondary to expressive aphasia. The patient was found to have a transient ischemic attack (TIA). A transesophageal echocardiogram (TEE) showed a thrombus on the watchman device (WD). The patient was treated with unfractionated heparin infusion and later transitioned to apixaban without any further TIA or stroke over 30 days period. Device-related thrombosis (DRT) with systemic thromboembolism occurred almost after 480 days of putting the WD which is very rare.

Staphylococcus lugdunensis native tricuspid valve endocarditis: a case report and review of literature.

Coagulase negative staphylococci are skin commensals and are generally disregarded as contaminants in clinical specimens. Repeated isolation of coagulase negative staphylococci in blood cultures should warrant a species identification to recognize unusually virulent organisms that demand aggressive treatment, such as Staphylococcus lugdunensis. Staphylococcus lugdunensis is known to cause a wide variety of infections, including a predominant left-sided endocarditis. We report a rare case of native tricuspid valve Staphylococcus lugdunensis endocarditis in a non-intravenous drug user and include a brief literature review.
