Insights
Dextrocardia with situs inversus totalis is rare. Minimally invasive off-pump coronary artery bypass grafting was successfully performed in a patient with triple-vessel disease, achieving three grafts.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Conditions
- Minimally Invasive Cardiac Surgery
Background:
- Dextrocardia with situs inversus totalis is a rare congenital condition.
- Surgical revascularization for coronary artery disease in these patients is infrequently reported.
- Previous minimally invasive approaches were limited to single-vessel disease with one graft.
Observation:
- A 65-year-old female patient presented with triple-vessel obstructive coronary artery disease.
- The patient had dextrocardia and situs inversus totalis.
- A minimally invasive surgical approach was considered due to the patient's complex anatomy.
Findings:
- The patient successfully underwent off-pump coronary artery bypass grafting (OPCABG) via a partial sternotomy.
- Three coronary artery bypass grafts were successfully constructed.
- This represents a novel application of minimally invasive cardiac surgery for complex coronary disease in a patient with dextrocardia and situs inversus totalis.
Implications:
- Minimally invasive OPCABG is a feasible and effective treatment option for patients with dextrocardia and situs inversus totalis presenting with multi-vessel coronary disease.
- This approach may offer advantages over traditional sternotomy in select patient populations.
- Further research and case series are warranted to establish the long-term outcomes and expand the application of this technique.
Abstract:
Dextrocardia associated with situs inversus totalis is a rare congenital condition. A small number of cases with these conditions have been reported who underwent myocardial revascularization via the on-pump or off-pump techniques. Among them, only 1 patient with dextrocardia and situs inversus totalis was reported to have the procedure performed with minimally invasive coronary surgery via a right anterior small thoracotomy. However, the case was a single-vessel disease and only one graft was achieved. We describe the case of a 65-year old female patient with triple-vessel obstructive coronary diseases who was successfully revascularized with three grafts using a minimally invasive technique. This was achieved via partial sternotomy and employing off-pump coronary artery bypass grafting.
