Insights
Minimally invasive right heart surgery is complex, especially isolating the vena cava in patients with enlarged atria. A new balloon catheter technique for temporary vessel occlusion simplifies these challenging procedures.
Area of Science:
- Cardiovascular Surgery
- Medical Device Technology
Background:
- Minimally invasive cardiac surgery presents unique challenges for right heart procedures.
- Effective caval isolation is particularly difficult in patients with enlarged and pressurized atria.
Observation:
- A novel technique using a balloon catheter for temporary large vessel occlusion was employed.
- This method facilitated minimally invasive closure of an ostium secundum atrial septal defect.
Findings:
- The new caval occlusion technique provided excellent surgical site visibility.
- The procedure resulted in successful minimally invasive closure of the atrial septal defect using a bovine pericardial patch.
Implications:
- This technique may enhance the feasibility and safety of minimally invasive cardiac procedures.
- It offers a potential solution for caval isolation challenges in various clinical settings.
Abstract:
Right heart surgery is challenging in the minimally invasive cardiac surgery setting, particularly in terms of caval isolation procedures in patients with enlarged and pressurized atria. We describe a novel minimally invasive caval occlusion technique with the use of a balloon catheter designed for temporary large vessel occlusion. A patient with a large ostium secundum atrial septal defect and significant shunt flow underwent a successful minimally invasive closure of the pathological connection between atria with a bovine pericardial patch. The utilized occlusion technique provided excellent visibility of the surgical site and may facilitate minimally invasive procedures in various clinical scenarios.
