Insights

Cardiac implantable electronic device (CIED) implantation is more common and occurs earlier after transcatheter aortic valve replacement (TAVR) than surgical aortic valve replacement (SAVR). Mitral valve interventions showed similar CIED implantation rates between surgical and transcatheter approaches within 180 days.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Health Services Research

Background:

  • Valvular heart disease interventions frequently necessitate cardiac implantable electronic device (CIED) implantation due to conduction disturbances.
  • Limited data exist on delayed CIED implantation, surgical comparisons, and outcomes after mitral valve interventions.

Purpose of the Study:

  • To compare the incidence and timing of CIED implantation within 180 days following surgical and transcatheter aortic and mitral valve interventions.

Main Methods:

  • Analysis of the Nationwide Readmissions Database (2016-2021).
  • Identification of patients undergoing transcatheter aortic valve replacement (TAVR), surgical AVR (SAVR), transcatheter mitral valve replacement/repair (TMVR/TEER), or surgical MVR (SMVR).
  • Evaluation of 180-day readmissions for CIED implantation using weighted analyses and Cox proportional-hazards models.

Main Results:

  • Transcatheter patients were older with higher comorbidity burden.
  • 180-day CIED implantation readmission rates were higher after TAVR vs. SAVR (2.33% vs. 0.88%; aHR 2.05), occurring earlier post-TAVR (median 10 vs. 49 days).
  • TMVR/TEER and SMVR showed similar 180-day CIED implantation rates (1.66% vs. 1.71%). Aortic interventions had early CIED clusters, while mitral interventions showed a more even distribution.

Conclusions:

  • CIED implantation readmissions occur earlier after aortic valve interventions compared to mitral valve interventions.
  • TAVR had a higher incidence of CIED implantation readmissions than SAVR, but mitral interventions had comparable rates between surgical and percutaneous approaches.
  • Findings inform rhythm monitoring strategies post-discharge following valve interventions.

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
