Abstract
Objective:
To compare the safety and effectiveness of video-assisted thoracic surgery (VATS) versus conventional median sternotomy (open) in the repair of secundum atrial septal defect (ASD) or patent foramen ovale (PFO).
Design:
Among 415 consecutive patients undergoing open or VATS ASD/PFO closure between 1993 and October 2012, 153 patients were compared using 2:1 frequency matching (n = 102 open vs 51 VATS). Matching variables include age, gender, body surface area, past medical history of neurologic events, and need of patch closure. Median age was 43 years (3-71 years), and 67% were female.
Results:
There were no early deaths in either group. There were no conversions to open sternotomy. Although mean cross-clamp time (14.5 ± 7.6 vs 26.3 ± 13.2 minutes, P < .001) and bypass time (31.7 ± 13.8 vs 60.9 ± 20.9 minutes, P < .001) were longer in the VATS group, patients who underwent VATS had shorter postoperative ventilation time (7.5 ± 6.4 vs 4.4 ± 2.8 hours, P = .03) with 62.7% extubated in the operating room, along with shorter intensive care unit stay (26.7 ± 10.8 vs 19.1 ± 9.9 hours, P < .001) and hospital stay (5.2 ± 1.9 vs 3.5 ± 0.9 days, P < .001). At early follow-up (mean 1.5 years, maximum 4.2 years), there was no difference in need for reintervention. Of the 27 patients who underwent VATS ASD/PFO closure for a neurologic event, none had a recurrence.
Conclusion:
The use of VATS provides a safe, equally effective alternative to conventional sternotomy for ASD/PFO closure, using a less invasive approach.
