Insights

This study details a rare congenital heart defect, common atrium (CA), in a 57-year-old woman. The case highlights complications including atrial fibrillation and AV block during treatment for this complex cardiac anomaly.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Electrophysiology

Background:

  • Common atrium (CA), a rare congenital anomaly, is characterized by the absence of the atrial septum and potential atrioventricular (AV) valve malformations.
  • This case involves a 57-year-old woman with CA, complicated by Eisenmenger syndrome and inferior vena cava interruption.

Observation:

  • The patient presented with symptomatic persistent atrial fibrillation (AF).
  • An initial pulmonary vein isolation procedure was successful.
  • A subsequent procedure for perivalvular atrial flutter led to inadvertent complete AV block.

Findings:

  • The complete AV block was attributed to an unusual location of the AV node within the complex anatomy of common atrium.
  • This case underscores the challenges in managing arrhythmias in patients with common atrium.

Implications:

  • Understanding the unique anatomical variations in common atrium is crucial for successful electrophysiological interventions.
  • This case highlights the need for careful pre-procedural planning and awareness of potential complications in rare congenital heart diseases.
  • Further research into managing complex cardiac anomalies like CA is warranted to improve patient outcomes.

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
