Key result
Long-sheath aortic balloon valvuloplasty is associated with ~46% shorter procedure times than conventional approaches.
Why the study?
A technique providing easier and quicker access with increased balloon stability during aortic balloon valvuloplasty was needed to reduce procedural difficulties and duration.
Does the long-sheath technique reduce procedure duration and improve safety/stability compared to a conventional approach in patients undergoing aortic balloon valvuloplasty for severe aortic stenosis?

Does the long-sheath technique reduce procedure duration and improve safety/stability compared to a conventional approach in patients undergoing aortic balloon valvuloplasty for severe aortic stenosis?
The long-sheath technique significantly reduces procedure time and provides increased balloon stability during percutaneous aortic balloon valvuloplasty for severe aortic stenosis.
Long sheath feasible in small aortic valvuloplasty series; leaves open safety and efficacy versus standard approaches.
A new 100 cm long 16.5 French valvuloplasty introducer was used in 12 consecutive patients (mean age 73 years, five males and seven females) undergoing aortic balloon valvuloplasty for severe aortic stenosis. The long‐sheath was introduced into the ascending aorta along the stiff part of an exchange guidewire. The valvuloplasty procedure, which included a complete diagnostic catheterization in three patients, lasted 113 ± 47 min (211 ± 81 min in the previous 18 procedures performed with a conventional approach, P < 0.05). Introduction of balloon catheters (3 × 12 mm trefoil balloon in the 12 cases and 2 × 19 mm bifoil balloon in 2 of these cases) was possible in all patients and an increased stability of the balloon during inflation was observed. No systemic embolization or vascular complications occurred at the puncture site. The long‐sheath technique appears to be a valuable adjunct for aortic valvuloplasty in that it provides easier and quicker access for even the largest balloons and additional support and stability during balloon inflation. In our experience, this reduced the practical difficulties and the duration of the procedure.

Serruys et al. (1988) conducted a cohort in Severe aortic stenosis (n=12). Long-sheath technique (100 cm long 16.5 French valvuloplasty introducer) vs. Conventional approach was evaluated on Procedure duration (p=<0.05). The long-sheath technique for aortic balloon valvuloplasty significantly reduced procedure duration compared to a conventional approach (113 vs 211 minutes; P<0.05).
