Insights

A rare case of adult left ventricular diverticulum, a congenital heart anomaly, was found in a 63-year-old man presenting with atrial flutter and heart failure. This extremely rare finding highlights the importance of considering congenital heart disease in adult cardiac conditions.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Imaging

Background:

  • Left ventricular diverticulum (LVD) is a rare congenital cardiac anomaly, typically diagnosed in infancy or childhood.
  • Adult presentation of LVD is exceptionally uncommon, often associated with other cardiac abnormalities.

Observation:

  • A 63-year-old male presented with atrial flutter and congestive heart failure.
  • Cardiac catheterization identified an anterobasal left ventricular diverticulum with a narrow ostium.
  • Coronary angiography demonstrated normal coronary arteries.

Findings:

  • The patient was asymptomatic until adulthood, with no other detected thoracoabdominal or cardiac anomalies.
  • This case represents an extremely rare instance of an isolated left ventricular diverticulum presenting in an adult.
  • The diverticulum's location and narrow connection suggest a congenital origin, presenting atypically late in life.

Implications:

  • This case underscores the importance of considering congenital heart anomalies, even in adult patients with seemingly acquired cardiac conditions.
  • Late-presenting LVD may contribute to arrhythmias and heart failure, necessitating accurate diagnosis and management.
  • Further research into the natural history and long-term outcomes of adult-onset LVD is warranted.
