The Mortality Burden of Untreated Aortic Stenosis.

Background: The American College of Cardiology/American Heart Association guidelines recommend the assessment and grading of severity of aortic stenosis (AS) as mild, moderate, or severe, per echocardiogram, and recommend aortic valve replacement (AVR) when the AS is severe.

Objectives: The authors sought to describe mortality rates across the entire spectrum of untreated AS from a contemporary, large, real-world database.

Methods: We analyzed a deidentified real-world data set including 1,669,536 echocardiographic reports (1,085,850 patients) from 24 U.

Structural Valve Deterioration in Transcatheter Aortic Bioprostheses: Diagnosis, Pathogenesis, and Treatment.

Transcatheter aortic valve replacement has emerged as the preferred treatment modality in most patients with severe aortic stenosis. With its global adoption and broader application in younger and healthier patients, the issue of transcatheter bioprosthetic valve degeneration and its impact on valve durability continues to earn clinical relevance. Differences in the pathophysiologic processes that separate native from transcatheter heart valve deterioration remain poorly understood.

Characteristics and immediate outcomes of patients who underwent percutaneous balloon mitral valvuloplasty at the Jakaya Kikwete Cardiac Institute, Tanzania.

Background: For rheumatic mitral stenosis (MS), a multidisciplinary evaluation is mandatory to determine the optimal treatment: medical, percutaneous balloon mitral valvuloplasty (PBMV) or valve surgery. Clinical and imaging evaluations are essential for procedural risk assessment and outcomes. PBMV interventions are increasingly available in Africa and are feasible options for selected candidates.

Association of ACEI/ARB and statin prescribing patterns with mortality after Transcatheter Aortic Valve Replacement (TAVR): Findings from real-world claims data.

Background: Transcatheter aortic valve replacement (TAVR) has become the standard of care for most patients with severe aortic stenosis (AS), but the impact of medical therapy prescribing patterns on post-TAVR patients has not been thoroughly investigated.

Methods: We analyzed Optum claims data from 9,012 adults who received TAVR for AS (January 2014-December 2018). Pharmacy claims data were used to identify patients who filled ACEI/ARB and/or statin prescriptions during the study's 90-day landmark period post-TAVR.

Contemporary Management of Concomitant Cardiac Arrest and Cardiogenic Shock Complicating Myocardial Infarction.

Cardiogenic shock (CS) and cardiac arrest (CA) are the most life-threatening complications of acute myocardial infarction. Although there is a significant overlap in the pathophysiology with approximately half the patients with CS experiencing a CA and approximately two-thirds of patients with CA developing CS, comprehensive guideline recommendations for management of CA + CS are lacking. This paper summarizes the current evidence on the incidence, pathophysiology, and short- and long-term outcomes of patients with acute myocardial infarction complicated by concomitant CA + CS.

Prosthetic valve leaflet perforation resulting in critical aortic insufficiency: A rare late complication after use of Cor-knot®.

The implementation of automatic fasteners such as the Cor-knot® device (LSI Solutions, Inc.) has revolutionized the field of minimally invasive valvular surgery. Nonetheless, paravalvular regurgitation, valvular embolization, and early leaflet perforation are all potential complications which may occur.
