Insights
This study presents a rare case of double inlet left ventricle with aortic hypoplasia originating from the main ventricular chamber. We discuss diagnostic electrocardiographic findings and surgical considerations for this complex congenital heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Morphology
Background:
- Double inlet left ventricle (DILV) typically involves hypoplastic great arteries arising from the accessory right ventricular chamber.
- Restrictive bulbo-ventricular foramen is a common cause of great artery hypoplasia in DILV.
- Understanding variations in great artery origin is crucial for diagnosis and management.
Observation:
- A unique case of DILV is presented where the hypoplastic aorta originated from the main ventricular chamber.
- This anatomical variation differs from the typical presentation of DILV with hypoplastic great arteries.
Findings:
- Electrocardiographic findings are analyzed for differential diagnosis, particularly distinguishing from isolated aortic coarctation.
- Associated intraventricular anatomical malformations contributing to hypoplastic vessels are reviewed.
- The study highlights the unusual origin of the hypoplastic aorta in the presented case.
Implications:
- Accurate diagnosis through electrocardiography and imaging is vital for appropriate management of such complex DILV cases.
- Review of surgical procedures offers insights for potential interventions in similar rare anatomical presentations.
- This case expands the understanding of anatomical variations within DILV, informing future clinical practice and research.
Abstract:
In cases with double inlet left ventricle when there exists a hypoplasia of one of the great arteries, the affected vessel arises from the accessory right ventricular chamber. This is due in general to the presence of a restrictive bulbo-ventricular foramen that results in hypoplasic vessel. The case we present in this paper has unusual anatomic morphology: the hypoplasic vessel (the aorta) arises from the main ventricular chamber. We analyse the electrocardiographic findings useful for the differential diagnosis from cases of isolated aortic coarctation of hypoplasia. We review also the intraventricular anatomic malformations that may cause the presence of a hypoplasic vessel. Even if, our patient died in the neonatal period, the adequate surgical procedure for this case is reviewed.
