The operation is performed under general anesthesia. The four pulmonary veins are reconnected to the left atrium, and any associated heart defects such as atrial septal defect, ventricular septal defect, patent foramen ovale, and/or patent ductus arteriosus are surgically closed. With obstruction, surgery should be undertaken urgently.
The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. The pulmonary veins are part of the pulmonary circulation.
Pulmonary vein stenosis can be congenital or acquired. [6]A rare abnormality that accounts for 0.4% of congenital heart diseases, congenital pulmonary vein stenosis results from the common right or left pulmonary vein failing to integrate into the left atrium (LA) during the vessel's embryonic development, obliterating the pulmonary veins partially or completely on one or both sides.
The left atrial appendage can serve as an approach for mitral valve surgery. [16] The body of the left atrial appendage is anterior to the left atrium and parallel to the left pulmonary veins. The left pulmonary artery passes posterosuperiorly and is separated from the atrial appendage by the transverse sinus. [17]
When the blood returns to the heart from the lungs via the pulmonary vein, it goes to the left side of the heart, entering the upper left atrium. Blood is then pumped to the lower left ventricle and from there out of the heart to the body via the aorta. This is called the systemic circulation. A cardiac shunt is when blood follows a pattern ...
Oxygenated blood leaves the lungs through pulmonary veins, which return it to the left part of the heart, completing the pulmonary cycle. [3] [6] This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. [3] [6] From the left ventricle, the blood passes through the aortic valve to the aorta.
In one case study a 40-year-old female was given a pericardial patch to close the atrial septal defect and then anastomosed the PSLVC directly to the left pulmonary artery. [1] Thus, getting rid of the leakage of blood to the left atrium and ensuring the blood from the PSLVC is directed into the right side of the heart and pumped to the lungs. [1]
This improves the drainage from the pulmonary veins, and signs and symptoms of pulmonary congestion will decrease. [citation needed] These changes in the left ventricle and left atrium improve the low forward cardiac output state and the pulmonary congestion that occur in the acute phase of the disease.
