Hardware entrapment during percutaneous coronary intervention is a significant complication necessitating proactive anticipation by interventionists. Here we present a case of a 59-year-old man with a history of stent placement in LAD 1 month back, who now presented with stent thrombosis and acute ST-elevation MI. Percutaneous intervention was done for thrombus aspiration through the previously deployed stent, but the thrombus aspiration device (thrombuster) got stuck in the stent. Despite attempted percutaneous retrieval methods, the device remained inaccessible, leading to emergency surgical device retrieval and simultaneous coronary bypass.

Background: There is a need for additional data to assess procedural efficacy and risks associated with mechanical thrombectomy for treating pulmonary embolism (PE) due to its increased utilization and diversity of patient populations presenting with PE. This study evaluated the safety and efficacy of percutaneous mechanical aspiration thrombectomy with the AlphaVac F18 System (AngioDynamics) in patients with acute intermediate-risk PE.
Methods: Patients with acute intermediate-risk PE and a right ventricular (RV)/left ventricular (LV) diameter ratio of ≥0.

Background: The thrombogenic potential of cells within atherosclerotic plaques is critical in the formation of a coronary thrombus. We hypothesized that a combination of inflammatory and hypoxic stimuli enhances tissue factor (TF) expression and glycolysis in cells in atherosclerotic plaques and contributes to coronary thrombus formation.
Aims: To identify TF- and hexokinase (HK)-II-expressing cells in coronary atherosclerotic plaques and thrombi and determine the effects of combined inflammatory and hypoxic stimuli and glycolysis on TF expression in peripheral blood mononuclear cell-derived macrophages.

Background: Effective myocardial reperfusion in ST-Elevation Myocardial Infarction (STEMI) remains challenging despite advancements in primary percutaneous coronary intervention (PCI). This study evaluates the impact of thrombus aspiration (TA) and saline autotransfusion (SAT) compared to standard PCI (NOTA) on coronary flow dynamics and myocardial perfusion.
Research Design And Method: This prospective cohort study enrolled 157 STEMI patients who underwent primary PCI.
A 77 year old man with recurrent lower extremity thrombosis presented with acute onset shortness of breath and new onset hypoxemia three days after prostatectomy for adenocarcinoma of the prostate. He had been off anticoagulation during the perioperative period. In addition to his new diagnosis of prostate cancer he also had a remote history of treated non-invasive melanoma.
