Insights
Minimally invasive coronary artery fistula (CAF) correction without cardiopulmonary bypass is feasible and safe. This approach offers excellent exposure and a cosmetic alternative to conventional methods, potentially reducing hospital stays.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Techniques
- Congenital Heart Disease
Background:
- Coronary artery fistulas (CAFs) are abnormal connections between a coronary artery and a cardiac chamber or great vessel.
- Minimally invasive cardiac surgery (MICS) is increasingly adopted for various cardiac procedures.
- The feasibility of MICS for CAF correction requires further investigation.
Purpose of the Study:
- To evaluate the feasibility and outcomes of a minimally invasive approach for coronary artery fistula (CAF) correction.
- To assess the safety, efficacy, and potential benefits of MICS for CAF repair compared to traditional methods.
Main Methods:
- A retrospective analysis of 49 patients who underwent minimally invasive CAF correction without cardiopulmonary bypass (CPB) between February 2001 and June 2014.
- Exclusion criteria included patients with cardiac anomalies and those requiring CPB for MICS CAF correction.
- Surgical approaches included subxiphoid and parasternal incisions.
Main Results:
- No in-hospital mortalities or conversions to median sternotomy were reported.
- The mean operative time was 67.45 ± 22.69 minutes, with a mean intubation time of 3.72 ± 1.82 hours.
- A single patient had a trivial residual shunt, which resolved by discharge; intensive care unit (ICU) stay averaged 9.67 ± 5.43 hours.
Conclusions:
- Minimally invasive CAF correction without CPB provides excellent surgical exposure for select patients.
- This approach is a safe and cosmetic alternative to conventional surgery.
- MICS for CAF repair may lead to a minimized length of hospital stay.
Objectives:
Minimally invasive cardiac surgery has recently become widespread. The aim of this study is to analyse the feasibility of a minimally invasive approach for coronary artery fistula (CAF) correction.
Methods:
From February 2001 to June 2014, 49 patients in our centre underwent minimally invasive CAF correction without cardiopulmonary bypass (CPB). The mean age was 21.18 ± 11.24 years (range, 5 months to 64 years). Patients with cardiac anomalies who underwent CAF correction and those who underwent CAF via the minimally invasive approach with CPB were excluded.
Results:
There were no in-hospital mortalities or conversions to median sternotomy. Subxiphoid incisions (22 cases) and parasternal incisions (20 cases) were the most commonly used approaches for the procedure. The operative time was 67.45 ± 22.69 min (30-125 min). The intubation time was 3.72 ± 1.82 h (2-12 h), and the ICU stay was 9.67 ± 5.43 h (4-24 h). A trivial residual shunt was identified in only 1 patient during the procedure; however, this shunt had disappeared by discharge.
Conclusions:
The minimally invasive approach can provide excellent surgical exposure for CAF ligation in select patients. This approach is a safe and cosmetic alternative to conventional treatment and may minimize the length of stay.
