Insights

Catheter ablation for adult congenital heart disease (ACHD) increased significantly over 15 years. Growing experience and technology improved procedural success and mid-term outcomes in ACHD patients.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Congenital Heart Disease

Background:

  • The adult congenital heart disease (ACHD) population is growing, leading to an anticipated rise in catheter ablation procedures.
  • Limited data exists on the experience and evolution of catheter ablation in ACHD patients over extended periods.

Purpose of the Study:

  • To analyze temporal trends in the volume of catheter ablation procedures performed in ACHD patients.
  • To evaluate the outcomes of catheter ablation in ACHD patients over a 15-year period.

Main Methods:

  • Retrospective observational study of consecutive ACHD patients undergoing attempted catheter ablation.
  • Analysis of acute procedural success and freedom from recurrence at 12 and 24 months.
  • Data collected over a 15-year period at a tertiary referral center.

Main Results:

  • The annual number of ablations increased from 4 to 60 cases (P<0.001).
  • Acute procedural success rose from 45.0% to 93.4% (P<0.001).
  • Freedom from recurrence at 12 months improved from 29.4% to 66.2% (P=0.001).

Conclusions:

  • Catheter ablation procedures in ACHD patients have markedly increased over 15 years.
  • Increased operator experience and technological advancements correlate with improved acute and mid-term outcomes.
  • The study highlights a positive trend in managing arrhythmias in the growing ACHD population.

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...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

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...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
