Why the study?

Does an extended vertical transeptal approach provide good exposure and safety compared to a conventional left atrial approach in patients undergoing mitral valve surgery?

Key Points

To assess the surgical exposure, procedural safety, and clinical outcomes associated with an extended vertical transeptal approach across the left atrial roof in mitral valve surgery.
Evaluated 111 consecutive patients undergoing mitral valve surgery via a vertical transeptal incision extended into the roof of the left atrium.
Compared cardiopulmonary bypass and aortic occlusion durations against a historical comparison cohort operated on via the conventional left atrial approach during the preceding year.
Optimal valve exposure was obtained in all 111 patients, including complex anatomies such as small left atria with right ventricular hypertrophy or preexisting aortic prostheses.
No approach-related hospital deaths occurred; two patients required reinstitution of cardiopulmonary bypass due to suture breakage or incomplete septal reconstruction, with both achieving an uneventful recovery.
Bypass and aortic occlusion durations did not differ significantly from conventional left atrial surgery, and only 3 of 52 patients (5.8%) with preoperative sinus rhythm were discharged in atrial fibrillation.

Structured PICO

Does an extended vertical transeptal approach provide good exposure and safety compared to a conventional left atrial approach in patients undergoing mitral valve surgery?

Population

111 patients undergoing mitral valve surgery, including those with unfavorable situations such as a small left atrium combined with right ventricular hypertrophy or a previously implanted aortic prosthesis.

Intervention

Extended vertical transeptal approach (vertical transeptal incision extended into the roof of the left atrium)

Comparator

Conventional left atrial approach (historical cohort from the preceding year)

Outcome

Surgical exposure quality and procedural complicationssafety

The extended vertical transeptal approach provides excellent surgical exposure for mitral valve surgery with comparable bypass times and a low complication profile.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports extended transeptal approach for mitral exposure in selected cases; leaves open need for randomized confirmation of safety.
