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.

[Acute myocardial infarction patients without COVID-19 manifestations in the pandemic may have high thrombus burden].

Objective: The objective of the study is to identify clinical and angiographic characteristics of patients with ST-segment elevation myocardial infarction (STEMI) but without clinical manifestations of COVID-19 infection during the pandemic, compared with patients 1 year before the pandemic.

Methods: Observational study that included 138 consecutive patients hospitalized with STEMI who underwent primary percutaneous coronary intervention (PCI) without COVID-19 infection during the 2020 pandemic. A group of 175 STEMI patients treated with PCI in the year before the pandemic served as the control group.

Left atrial veno-arterial extracorporeal membrane oxygenation in post-myocardial infarction ventricular septal defect with cardiogenic shock: a case report.

Background: Ventricular septal defect (VSD) complicating acute myocardial infarction (MI) represents a life-threatening condition and has a mortality of >90% if left untreated.

Case Summary: A 53-year-old man with a prior medical history of diabetes and hypertension presented with cardiogenic shock secondary to VSD as a mechanical complication of non-reperfused inferior MI.

Discussion: The choice of mechanical support can be difficult in this type of patient.

Left circumflex artery injury occurring during mitral valve surgery treated successfully with percutaneous intervention in a high surgical and bleeding risk patient.

Unlabelled: Perioperative myocardial infarction is a complication of cardiac surgery, and the cause can be multifactorial. Injury of the left circumflex coronary artery has been described, particularly after mitral valve replacement. We present the case of a 72-year-old woman who underwent mitral valve replacement but developed a lesion in the proximal circumflex coronary artery related to partial mechanical kinking caused by a suture.

Dynamic Invasive Hemodynamic Congestion Profile Impacts Acute Myocardial Infarction Complicated by Cardiogenic Shock Outcomes: A Real-World Single-Center Study.

Background: Cardiogenic shock (CS) commonly complicates the management of acute myocardial infarction (AMI), and it results in high mortality rates. Pulmonary artery catheter (PAC) monitoring can be valuable for personalizing critical-care interventions. We hypothesized that patients with AMI-CS experiencing persistent congestion measures during the first 24 hours of the PAC installment would exhibit worse in-hospital survival rates.

Aortic Perforation and Ascending Dissection Due to Intra-Aortic Balloon Counterpulsation Implantation in Cardiac Surgery.

The intra-aortic balloon pump continues to be a useful ventricular assist device in cardiac surgery. Complications are estimated to be 7% to 40%, significantly high to catastrophic. We describe an aortic injury associated with the use of the device and an interdisciplinary management for the diagnostic and therapeutic approach.

Cardiothoracic surgery and peripheral endovascular intervention in cardiovascular damage from a cohort of orphan rheumatological diseases-epidemiological and survival analysis.

Background: Aortic diseases in some orphan rheumatological diseases require medical, surgical or peripheral endovascular intervention because they can be catastrophic. Objectives: to analyze the main clinical and epidemiological characteristics of patients with Takayasu arteritis (TA), Marfan syndrome (MS) and similar conditions that were treated with cardiothoracic surgery and peripheral endovascular intervention.

Methods: Retrospective and descriptive cohort study that included patients of any age and gender with TA (as per the criteria of the American College of Rheumatology and EULAR/PRINTO), MS (according to Ghent criteria), and similar conditions who underwent cardiothoracic surgery or peripheral endovascular intervention.

Prevention of Radial Artery Occlusion of 3 Hemostatic Methods in Transradial Intervention for Coronary Angiography.

Objectives: The main objective of this study was to compare the efficacy of 3 hemostatic methods for the prevention of early radial artery occlusion (RAO): standard patent hemostasis, patent hemostasis with ulnar compression or the ulnar artery transient compression facilitating radial artery patent hemostasis (ULTRA) method, and facilitated hemostasis with a hemostatic disc.

Background: There are no prospective randomized studies that compare early RAO rates with the 3 most used nonocclusive hemostatic methods.

Methods: This was a prospective, longitudinal, comparative, and randomized study.

Cardiogenic Shock Among Patients with and without Acute Myocardial Infarction in a Latin American Country: A Single-Institution Study.

Background: Latin America has limited information about the full spectrum cardiogenic shock (CS) and its hospital outcome. This study sought to examine the temporal trends, clinical features and outcomes of patients with CS in a coronary care unit of single Mexican institution.

Methods: This was a retrospective study of consecutive patients hospitalized with CS in a Mexican teaching hospital between 2006-2019.

Acute Aortic Syndrome of Ascending Thoracic Aorta: Transcarotid Percutaneous Exclusion of a Ruptured Pseudoaneurysm.

Treatment of ascending aorta disease is surgical; however, some series have evaluated the effectiveness of endovascular treatment. We report the case of a patient with a ruptured pseudoaneurysm who underwent endovascular repair via the left common carotid artery. The clinical and neurological evolution was satisfactory during the in-hospital follow-up.

Pharmacoinvasive Strategy vs Primary Percutaneous Coronary Intervention in Patients With ST-Elevation Myocardial Infarction: Results From a Study in Mexico City.

Background: A low proportion of patients with ST-elevation myocardial infarction (STEMI) in low- to middle-income countries receive reperfusion therapy. Although primary percutaneous coronary intervention (PCI) is the method of choice, a pharmacoinvasive strategy (PIs) is reasonable when primary PCI cannot be delivered on a timely basis. The aim of our study was to assess the efficacy and safety of a PIs compared with primary PCI in a real-world setting.

Distal Radial Artery Approach to Prevent Radial Artery Occlusion Trial.

Objectives: The aim of this study was to compare the rate of proximal radial artery occlusion (RAO) with Doppler ultrasound between distal and conventional radial access 24 h and 30 days after a transradial coronary procedure.

Background: The use of distal radial access to prevent proximal RAO (PRAO) in the proximal segment at 24 h and 30 days after a procedure, compared with conventional radial access, is unknown.

Methods: This was a prospective, comparative, longitudinal, randomized study.
