Insights
Dextroversion, a rare heart condition, typically involves other cardiac abnormalities. This report details the first coronary artery bypass graft surgery in a patient with isolated dextroversion, highlighting surgical techniques.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Dextrocardia is a rare cardiac abnormality involving rightward cardiac axis deviation.
- Dextroversion, a specific type of dextrocardia with situs solitus, modifies the spatial relationships of cardiac chambers and adjacent organs.
- Associated cardiac anomalies are present in 95% of dextroversion cases, making isolated dextroversion exceedingly uncommon.
Observation:
- This case report presents the first instance of coronary artery bypass graft (CABG) surgery in a patient with isolated dextroversion.
- The patient had an isolated dextroversion, a condition where the heart's position is mirrored but without other congenital heart defects.
- The surgical procedure and its technical considerations in this unique anatomical context were meticulously documented.
Findings:
- Coronary artery bypass graft surgery was successfully performed on a patient with isolated dextroversion.
- The surgical team navigated the anatomical challenges posed by the dextroversion.
- This demonstrates the feasibility of complex cardiac interventions in rare congenital heart conditions.
Implications:
- This case expands the understanding of surgical possibilities for patients with rare cardiac malpositions.
- It provides valuable insights for surgeons planning interventions in patients with dextroversion.
- Further research into managing acquired heart disease in isolated dextroversion is warranted.
Abstract:
Despite several controversies, the term "dextrocardia" usually defines a rare type of intrinsic cardiac abnormality due to a rotation disorder and resulting in a right-sided direction of the cardiac axis. According to the majority of experts, the extent of a dextrocardia associated with a situs solitus is termed "dextroversion". In such a rare condition, therefore, the relationships between the cardiac chambers and the other structures (that is superior and inferior venae cavae, liver, stomach) are modified whereas in case of dextrocardia with situs inversus, the relationships between the cardiac chambers and neighboring structures are preserved and the classical "mirror image" is shown. In 95% of cases with dextroversion, an associated cardiac abnormality has been described and, therefore, acquired heart diseases in patients with isolated dextroversion are extremely rare. To our knowledge, the present is the first case report describing a coronary artery bypass graft performed in a patient with isolated dextroversion. The technical aspects of the surgical procedure are also discussed.
