What is the purpose of balloon atrial Septostomy?

What is the purpose of balloon atrial Septostomy?

Balloon atrial septostomy is a procedure to expand an atrial septal defect and improve oxygenation of the blood. It is often performed for children with transposition of the great arteries.

What is an atrial Septostomy procedure?

Atrial septostomy is a procedure where a small hole is made in the wall between the left and right atria of the heart. The hole can be made using a cardiac catheter (a thin flexible tube, which is inserted into the chambers or blood vessels of the heart).

Why is atrial Septostomy done?

Atrial septostomy allows more of the oxygen-rich blood to circulate throughout the body. The procedure is a temporary measure meant to help the patient survive until further corrective surgery can be done.

What is the Rashkind procedure?

In the balloon atrial septostomy (Rashkind procedure), a balloon-tipped catheter is advanced into the left atrium through the patent foramen ovale. The balloon is inflated and abruptly withdrawn to the right atrium thereby enlarging the opening in the atrial septum.

Who performed the first atrial Septostomy procedure?

6. Discussion. Balloon atrial septostomy (BAS) was first described in 1966 by Rashkind and Miller2 as palliation for patients with transposition of the great arteries to improve saturation.

What is a baffle in heart surgery?

A baffle is a surgically-created tunnel or wall within the heart or major blood vessels used to redirect the flow of blood.

What is D transposition of great arteries?

Español (Spanish) Dextro-Transposition (pronounced DECKS-tro trans-poh-ZI-shun) of the Great Arteries or d-TGA is a birth defect of the heart in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta – are switched in position, or “transposed.”

Why is atrial Septostomy used for pulmonary hypertension?

Balloon atrial septostomy increases cardiac index and may reduce mortality among pulmonary hypertension patients awaiting lung transplantation.

What is a catheter in the heart?

What is cardiac catheterization? In cardiac catheterization (often called cardiac cath), your doctor puts a very small, flexible, hollow tube (called a catheter) into a blood vessel in the groin, arm, or neck. Then he or she threads it through the blood vessel into the aorta and into the heart.

What is warden procedure?

The Warden procedure transfers the SVC to the RA appendage, while redirecting an anomalous pulmonary venous flow to the left atrium by using a single patch. This procedure essentially prevents the anatomical obstruction of the intracardiac blood flow. However, stenosis at the SVC-RA junction has been reported.

What is transposition of the great vessels?

What is pulmonary artery denervation?

Pulmonary artery denervation (PADN) is an innovative catheter-based ablation technique targeting the afferent and efferent fibers of a baroreceptor reflex in the main pulmonary artery (PA) trunk and its bifurcation. This reflex is involved in the elevation of the PA pressure seen in PH.

Why is Glenn shunt bidirectional?

The bidirectional Glenn procedure directs the blood flow from the upper body veins directly to the lungs rather than the heart pumping the blood to the lungs first. The bidirectional Glenn shunt redirects blood flow from the upper body veins and is often performed prior to having a Fontan procedure.

Which vein is used for cardiac catheterization?

The majority of right heart catheterization procedures in the cardiac catheterization laboratory are performed via the femoral vein, even when left heart catheterization is performed transradially.

Which wrist is used for heart cath?

The left wrist can be strapped to a soft wrist board, and a pulse oximeter probe is placed on the left index finger or thumb to allow continuous monitoring throughout the procedure.

What is a balloon atrial septostomy?

Balloon atrial septostomy (BAS) is the classic bail out procedure for the deeply cyanosed and acidotic newborn with d-transposition of great arteries (d-TGA) and poor admixture.

How is a balloon catheter placed in the left atrium?

The balloon catheter is advanced into the right atrium. Then the foramen ovale is crossed and the catheter is positioned in the left atrium. Correct position is documented via biplane fluoroscopy or two-dimensional echocardiography.

How do you deflate a balloon in a heart catheter?

The balloon is quickly inflated with 3-4 ml of dilute radiopaque solution, locked, and then sharply withdrawn into the right atrium down to the junction of the inferior caval vein. The catheter is then advanced into the body of the right atrium, so as not to obstruct inferior caval return, and then deflated rapidly.

What size sheath is used for septostomy catheter?

Thereafter, a standard 7F or 8F sheath can be used to introduce the septostomy catheter. When using a sheath in the umbilical vein, it must be borne in mind that the tip of the sheath is often inside the right atrium, and may impede withdrawal of the inflated balloon across the septum.
