An artery, by definition, carries blood away from the heart. The pulm. artery (PA) goes from the Right Ventricle to the lungs and has yet to be oxygenated. So the blood there is oxygen low. The blood returns to the Left side of the heart where it is pumped out of the aorta with highly oxygenated blood. It's kind of a matter of semantics. Hope that this helped, mate.

My father in law has just been told he has very high pressure in his pulmonary artery, (he has been treated for pulmonary embolisms for over 7 months with warfrin, with out success) he has just been refered to cardiac specialist who has told him has to under go major chest surgery? why and what are they going to do once they have opened his chest?? He has been told soft tissue is now growing over his embolisms and if he doesnt have surgery soon they may not be able to do any thing for him!

I am 41 and for the past 4 years the diagnosis has been massive pulmonary embolism - I went for an angiogram on the blood clot in preparation for surgery and the doctor and radiologist could not find the artery and now are concluding that I was not born with a pulmonary artery in my left lung - how can years of ct scans not diagnosis the missing artery sooner?

hi Doc, My baby (17 days old, weigh 4kg now - he was born 3,7kg) has Congenital Heart Disease. The Electrocardiograph report done when he was 2days old showed: - Presence of a moderated sized patent arterial duct with bidirectional shunting (mainly left to right) - Small to moderated sized perimembranous inlet VSD with septal aneurysm - Double secundum ASD with left to right shunting. -Mild tricuspid regurgitation and mild mitral regurgitation - Fast flow across right and left pulmonary arteries were noted. - Reassessment in one month age is recommended. He was born healthy just like normal baby. Doctor has found heart murmur on the 2nd day and suggested me to do echo of his heart (and i did as reported above). A ped cardiologist just suggested me to obsenrve and have another scan in a month time. To my observation, he started to develop symptoms such as sweating while nursing as well as hard breathing since day 8 (until now). And I have googled around that his disease is also called AVSD which is strongly associated with Down Syndrome. He, though, looks psychically fine to me (at least his face looks normal to me). Is my assumption of the down syndrome true enough? I have made my own physical examination to my son and found that he has got of the physical symptoms of having DS (small ears, gap between toe and second finger and probably low muscle tone). How can you help me in my uncertainty. I am really stressed of this situation. Thank you Doc

Hello, I would like international heart professionals to give me guidance and opinion on my infant son s heart issue. We experience numerous misdiagnosis and negligence in the healthcare area so any suggestions would be greatly appreciated. I was just told that my newborn son (12 days old) has respiratory problem. My wife had elevated sugar level on the week of the delivery. So she ended up in the hospital and had some insulin doses. She was also in controlled diet. When my son was born we were told that the baby had excessive breathing and we were asked to watch out for signs of blueness or abnormal breathing for a month and see if things will get better on his own. When we brought him home he started to have temperature of 101 so we brought him back to the hospital. They performed echocardiogram and found that baby has hole in his heart and may need surgery because of his issues in his heart. We took him to a heart specialist and did another round of echo. I have attached the results below. We were sent home and asked to monitor the baby. Once other reports are back the doctors will discuss the further actions. I don t know the details on that. Please help me translate below result. I just want to double check with international heart professionals before jumping into conclusion of performing a heart operation on an infant. Any suggestions would be helpful.

My husband passed away a few days ago. He had HBP, congenital heart malformations and CAD. He had heart surgery 3 years ago to replace his pulmonic valve and to resize his pulmonary artery which was more than twice the normal size; also, his LAD was bypassed. When he died, he was experiencing extreme reflux, profuse sweating, had blood coming out of his nose and mouth. No autopsy was performed. Do his symptoms point toward a rupture of the pulmonic artery or something else? I am a very private person and would like for this to remain confidential.
