Summary
A transversal trans-septal biatrial approach offers excellent mitral valve visualization, especially in small left atria. This surgical technique demonstrated no operative mortality and comparable procedure times to traditional methods.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Cardiac Valve Surgery
Background:
- Adequate visualization of mitral valve and subvalvular structures is crucial for successful surgical intervention.
- Traditional surgical approaches may be limited in cases of small left atria, hindering complete mitral valve exposure.
Purpose of the Study:
- To evaluate the efficacy and safety of a transversal trans-septal biatrial approach for mitral valve procedures.
- To assess the technique's utility in improving visualization, particularly when the left atrium is small.
Main Methods:
- A transversal trans-septal biatrial approach was utilized in 11 patients undergoing various mitral valve procedures between January and May 1994.
- Patient demographics, surgical indications (reoperations vs. first operations, specific valve pathologies), and concomitant procedures were recorded.
Main Results:
- No operative mortality was observed in the 11 patients.
- All patients maintained their preoperative cardiac rhythm, with no significant bleeding or supra-ventricular arrhythmias.
- Aortic cross-clamping and extracorporeal circulation times were comparable to the traditional approach.
Conclusions:
- The transversal trans-septal biatrial approach is an easy and effective technique for mitral valve exposure.
- It is particularly beneficial in procedures involving small left atria where traditional methods provide inadequate visualization.
