Insights
This study details two rare cases of combined double-chambered right and left ventricles, highlighting imaging findings and the rarity of this congenital heart anomaly. Further research is needed to understand its prognosis and inheritance.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Double-chambered right ventricle (DCRV) and double-chambered left ventricle (DCLV) are individually rare congenital cardiac anomalies.
- While DCRV has established management guidelines, information on combined DCRV and DCLV, including prognosis and inheritance, is scarce.
- Existing literature lacks detailed reports on the combined presentation of these conditions.
Observation:
- Presents two unique cases of combined double-chambered right and left ventricles in female patients of different ages (adult and infant).
- Utilizes computed tomography (CT) and magnetic resonance imaging (MRI) to illustrate the morphological similarities and differing patient demographics.
- Highlights the rarity of this combined condition, with only three similar cases previously reported in medical literature.
Findings:
- Demonstrates the diagnostic utility of advanced imaging techniques like CT and MRI in characterizing complex congenital heart defects.
- Confirms the extreme rarity of the combined DCRV and DCLV, with this report adding significantly to the existing case series.
- Underscores the need for further investigation into the specific clinical presentation and outcomes associated with this dual ventricular anomaly.
Implications:
- Suggests a need for enhanced awareness among clinicians regarding the combined DCRV and DCLV due to its rarity and potential diagnostic challenges.
- Emphasizes the importance of advanced cardiac imaging in the accurate diagnosis and characterization of complex congenital heart malformations.
- Calls for future research to establish clear management protocols and understand the long-term prognosis and potential genetic factors of combined DCRV and DCLV.
Abstract:
Double-chambered right ventricles (DCRV) and left ventricles are rare entities on their own. We present two cases with an unusual combination of double-chambered right as well as left ventricles. One was discovered in a 28-year-old female, while the other was found at birth in a female child. The differing nature of both the patient demographics as well as the presentation with a common morphological background is shown on both computed tomography and magnetic resonance imaging. The oldest description of an obstructive muscular band within the right ventricle was given in 1867. In the literature, there is ample description of the long-term prognosis and management guidelines for DCRV, but no inheritance patterns or risk factors have been identified except for associations with septal defects, tetralogy of Fallot and transposition of the great arteries. A combination of both double-sided left as well as right ventricles has been published in literature a few times with little details about management and prognosis. SIMILAR CASES PUBLISHED: Although many cases of DCRV and DCLV have been published, to our knowledge only 3 cases of combined DCRV and DCLV have been published in literature.

Anatomy of the Heart
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
