Abstract

Insights

Early infections after transcatheter aortic valve replacement (TAVR) affect about 1 in 10 patients and are linked to higher mortality rates. Close monitoring of TAVR patients with infections may improve outcomes.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Medical Device Technology

Background:

  • Transcatheter aortic valve replacement (TAVR) is a crucial procedure for aortic stenosis.
  • Understanding early post-TAVR infections is vital for patient management and outcomes.

Purpose of the Study:

  • To investigate the frequency, microbiological characteristics, predictors, and outcomes of early infections following TAVR.
  • To assess the impact of early infections on short- and long-term mortality after TAVR.

Main Methods:

  • A retrospective review of 539 patients who underwent successful TAVR between 2014 and 2019.
  • Definition of early infections as those occurring within 30 days post-TAVR.
  • Multivariable analysis to identify predictors and associations with mortality.

Main Results:

  • Early infections occurred in 11.3% of TAVR patients.
  • Pulmonary infections were most common (42.9%), followed by bloodstream infections (15.9%).
  • Early infections were independently associated with increased 30-day and 1-year mortality.

Conclusions:

  • Approximately 1 in 10 TAVR patients experience early infections, significantly increasing mortality risk.
  • While causality is complex, vigilant surveillance of TAVR patients with infections is recommended.
  • Improved monitoring may enhance TAVR procedure success rates and patient survival.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of 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...

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

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.
