What is a transseptal procedure?

The transseptal puncture is a routine procedure for cardiac electrophysiologists to access the left atrium, predominantly for ablation of atrial fibrillation. An intracardiac catheter should be used as an anatomical marker to avoid puncturing the aortic root.

What is transseptal catheterization?

Transseptal catheterization is used by interventional cardiologists to gain access in the left atrium. This technique was initially introduced for left-sided pressure measurements and has been integrated in a variety of procedures including left atrial ablations and percutaneous mitral valvuloplasties.

What is a Brockenbrough needle?

Brockenbrough™ curved needles are stainless steel and used to make the transseptal puncture. They are sterile, single-use products. Available in adult and pediatric sizes.

When performing a transseptal puncture what anatomy structure is targeted?

Created with Sketch. Transseptal puncture of the atrial septum as a means to access the left atrium for diagnostic purposes was initially described in the late 1950s.

What is a transseptal sheath?

The HeartSpan Fixed Curve Braided Transseptal Sheath is designed with a seamless dilator to sheath transition to assist with ease of femoral insertion as well as trauma reduction when crossing the atrial septum. Our braided sheath construction allows for curve durability and kink resistance during long procedures.

What does TMVR stand for?

TMVR, also known as transcatheter mitral valve replacement is a way of replacing the mitral valve in the heart without the need for conventional open-heart surgery.

What is the ideal transseptal puncture site for Teer?

The ideal site for transseptal puncture should also be >4 cm above the mitral annulus for degenerative MR and 3-4 cm for functional MR. The additional height is necessary in degenerative MR to avoid the leaflets that may prolapse above the annular plane.

What is transseptal puncture used for?

The transseptal puncture (TP) technique was introduced into clinical practice during the late 1950s by Ross et al as a diagnostic tool to properly select patients for cardiac valve surgery.

What is a fossa Ovalis?

The fossa ovalis is a depressed structure, of varying shapes, located in the inferior aspect of the right interatrial septum. [1] A remnant of an interatrial opening, the foramen ovale, which has a significant role in fetal circulation, the fossa ovalis forms by the fusion of the septum primum and septum secundum.

Is TMVR FDA approved?

While a number of technologies are in clinical development, an edge-to-edge leaflet repair device (the MitraClip) is currently the only US Food and Drug Administration (FDA) approved device for TMVR. The MitraClip, as well as the CARILLON mitral annuloplasty device, has CE Mark approval.

What is the difference between fossa ovalis and foramen ovale?

The foramen ovale becomes the fossa ovalis as the foramen closes while edge of the septum secundum in right atrium becomes anulus ovalis, so the depression beneath it becomes the fossa ovalis. This enables respiration and circulation independent from the mother’s placenta.
