Immediate Use of Impella CP for High-Risk Percutaneous Coronary Intervention After Repair of Thrombosed Aortic Coarctation.

Aortic coarctation represents up to 7% of congenital heart diseases and is associated with hypertension and coronary artery disease, which continues to be the leading cause of death even after successful surgical repair. However, there is limited knowledge of managing both conditions, especially in the setting of an acute coronary syndrome. We herein present the case of a 53-year-old man with a history of hypertension who initially presented with an ST-elevation myocardial infarction successfully treated with thrombolysis and hemodynamic compromise.

Senescent CD4+ T-Cell Phenotypes and Inflammatory Milieu in the Coronary and Systemic Circulation in ST-Elevation Myocardial Infarction: An Exploratory Study.

Introduction: In ST-elevation myocardial infarction (STEMI), inflammation is pivotal, with early senescent CD4+CD28null cells implicated in its pathogenesis. However, the functional phenotype of these cells within the coronary circulation remains unclear.

Methods: We examined CD4+ cell subpopulations in blood samples from the coronary sinus and vena cava of 24 STEMI patients and the cephalic vein of seven healthy controls.

Selective embolization with autologous fat to treat massive bleeding secondary to percutaneous renal biopsy.

Bleeding following a percutaneous renal biopsy is a complication that can be life-threatening. Embolization of the bleeding artery is a procedure that can limit the damage; however, embolization devices can be costly or not immediately available. This is why we present the case of a 25-year-old man with a history of multiple thromboses who underwent a renal biopsy due to suspected systemic lupus erythematosus.

Thrombocytopenia after transcatheter aortic valve implantation.

Introduction And Objectives: Thrombocytopenia frequently occurs after transcatheter aortic valve implantation (TAVI) but its impact is poorly understood. We aimed to analyze the incidence, clinical impact, and predictors of acquired thrombocytopenia after TAVI.

Methods: This retrospective multicenter registry included 3913 patients undergoing TAVI with a baseline platelet count of ≥ 100 *10/L.

Prevalence and prognostic implications of the no-reflux phenomenon in patients undergoing primary percutaneous coronary intervention at a university center in a middle-income country.

Objective: To analyze the prevalence of no-reflow and the 30-day mortality in a university center in a middle-income country.

Method: We analyzed 2463 patients who underwent primary PCI from January 2006 to December 2021. The outcome measure was 30-day mortality.
