Key result
Extended vertical transseptal approach yields similar postoperative AF rates versus standard approach in mitral surgery.
Why the study?
Does the extended vertical transseptal approach improve surgical outcomes or maintain sinus node function compared to the transseptal approach in patients undergoing mitral valve operations?
Cohort (n=72)
Does the extended vertical transseptal approach improve surgical outcomes or maintain sinus node function compared to the transseptal approach in patients undergoing mitral valve operations?
Absolute Event Rate: 15.4% vs 15.4%
The extended vertical transseptal approach provides adequate mitral valve exposure and is as safe as the standard transseptal approach for maintaining sinus node function.
No takes yet. Share an insight, caveat, or question.
Similar postoperative AF rates support safety of extended approach; leaves open need for randomized trials on exposure and sinus node function.
Wang et al. (2014) conducted a cohort in Mitral valve disease requiring surgery (n=72). Extended vertical transseptal approach vs. Right atrium transseptal approach was evaluated on Postoperative atrial fibrillation in patients with normal preoperative sinus rhythm. The extended vertical transseptal approach for mitral valve operations resulted in similar rates of postoperative atrial fibrillation (15.4% vs 15.4%) compared to the standard transseptal approach.
