2004年2月5日 · The advantages of the Potts procedure are the immediate decrease in the right ventricular afterload and the absence of cyanosis of the upper part of the body in the absence of intracardiac...

The Potts shunt is a novel alternative technique for decompressing the right ventricle without significant upper body cyanosis. It is a surgical technique in which a side-to-side anastomosis is created from the left pulmonary artery to the descending aorta, resulting in a right-to-left shunt.

A surgical procedure known as a Potts shunt is an old technique that is showing promise as an alternative therapy for treating children with severe, drug-resistant PH, possibly delaying or even negating the need for lung transplantation.

Reversed Potts shunt was shown to improve WHO functional class, 6-minute walk distance, NTpro-BNP level, and hemodynamic parameters including tricuspid annular plane systolic excursion, interventricular septal curvature, and end-diastolic right ventricle/left ventricle ratio.

Potts shunt is feasible in patients with PAH without significant intra or extracardiac shunts. It can be done safely with an acceptable success rate. Patient selection, preoperative stabilization, and meticulous postoperative management are essential.

2021年8月1日 · In connection with an increased pulmonary arterial pressure, which exceeds that of the systemic circulation, the resulting right-to-left shunt is summarized as reverse Potts shunt (rPS).

The reverse Potts shunt was introduced in the early 2000s as a therapy to reduce the pressure load on the right ventricle in patients with suprasystemic pulmonary artery pressure and preserve the function of the right ventricle.2

A Potts shunt has been proposed as effective palliative therapy in children with severe pulmonary hypertension (PH) who have suprasystemic right ventricular pressures.

The most common technique for shunt creation in this study was a traditional Potts shunt with direct anastomosis of the left pulmonary artery and descending aorta via a left thoracotomy. However, in a number of children, a tube graft was used to complete the connection.

The Potts shunt is a palliative procedure designed to improve pulmonary blood flow in those with cyanotic heart disease; in its reversed form, it is now used to palliate patients with refractory pulmonary hypertension.
