Insights

Complications after stenting for congenital heart disease are common, with stent malpositioning being frequent. Combining operator experience and using premounted stents may reduce risks in these complex pediatric cardiology procedures.

Area of Science:

  • Interventional Cardiology
  • Congenital Heart Disease
  • Pediatric Cardiology

Background:

  • Stenting is a key intervention for congenital heart disease.
  • While generally successful, stenting procedures carry risks of complications.

Purpose of the Study:

  • To evaluate early complications following stenting in congenital heart disease patients.
  • To identify potential risk factors associated with these complications.

Main Methods:

  • Retrospective study of 309 patients undergoing 366 catheterizations with 464 stents across 13 anatomical positions.
  • Data collected from a combined Dutch-Belgian cohort.

Main Results:

  • 19% of stenting procedures (72/366) resulted in complications, with 5.7% (24/366) being major.
  • Procedure-related deaths occurred in 2.3% (7/309) of patients.
  • Stent malpositioning/embolization (7.7%) was the most common complication; non-premounted stents and center inexperience were linked to higher complication rates.

Conclusions:

  • Complications are frequent in congenital heart disease stenting due to anatomical diversity and small patient groups.
  • Consolidating operator experience can mitigate stenting risks.
  • Premounted stents may decrease stent migration and embolization.

Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

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.
