Double-orifice mitral valve: report of two cases

Summary
This study reports two rare cases of double-orifice mitral valve, a congenital heart anomaly. Echocardiography clearly identified the valve morphology and associated cardiac defects.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Echocardiography
Background:
- Double-orifice mitral valve (DOMV) is a rare congenital cardiac anomaly.
- DOMV can be associated with other significant cardiac malformations.
Observation:
- Case 1 presented with DOMV, coarctation of the aorta, and a perimembranous ventricular septal defect.
- Case 2 involved DOMV, a patent ductus arteriosus, and a unique accessory mitral valve opening.
- A bridge-type defect created two equal mitral valve orifices in Case 1.
Findings:
- The precise morphology of DOMV was clearly visualized using 2-D echocardiography in both cases.
- DOMV demonstrates variable anatomical presentations, as evidenced by the two distinct cases.
Implications:
- Early and accurate diagnosis of DOMV is crucial for managing associated congenital heart defects.
- 2-D echocardiography is an effective tool for delineating DOMV morphology and guiding clinical management.
- Understanding the spectrum of DOMV presentations aids in surgical planning and prognosis assessment.
