Enlarged Main Pulmonary Artery
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
A pulmonary artery that is 31 mm and aortic artery is 3.7 and a borderline enlargement heart is that classified as pulmonary arterial hypertension?
No. Need RVSP.: To diagnose pulmonary arterial hypertension (PAH), you need to have (1) a description of symptoms that you experience that is consistent with PAH, and (2) a measurement or estimate of the pulmonary arterial pressure - either by echocardiogram or by Swan-Ganz (right heart) catheterization. Only after a doctor has obtained this information can you diagnose PAH. Use HealthTap Prime to discuss. ...Read more
Shortness of breath, fatigue & dizziness for a year. My doctor accidentally discovered an enlarged pulmonary artery. What conditions would cause this?
My pulmonary artery was sightly enlarged on chest X-ray & CT (having chest pain, dizziness).Echo showed I do not have pulm htn. Should I be concerned of arteryll? 'm being treated for ctd, likely lupus
No, but follow: It is not a big deal if you do not have plum a. Htn (pah). You may just have a generously sized pulm. A. However, since you are on treatment for a rheumatologic problem, you should follow up every year with a cardiologist for a repeat echo to evaluate for pah and any other problems related to your ctd. Echo is much better than ct as there's no radiation and it's an exam of the heart at work.... ...Read more

Pda: If there is a right sided aortic arch, there could be a PDA to the right pa branch, this would require several simultaneous congenital malformations which would have a very low probability. ...Read more
Length: CVP catheter can not go beyond the right atrium and therefore it is less than 50 cm long. In contrast pulmonary artery catheter can go past the pulmonary artery and into the pulmonary capillaries and it is over 100cm long. In addition it has a balloon tip to facilitate the positioning of the catheter into the pulmonary artery via a peripheral vein. ...Read more
What does this mean Other Anomalies Of Pulmonary Artery And Pulmonary Circulation with collateral flow?
Partial description: That sounds like only part of a larger description? Anomalies usually refers to a congenital or birth defect. Collateral flow means blood is reaching its target tissue by alternate routes. Taken all together, my guess is: there is some congenital obstruction or diversion of blood from the right ventricle thru the lungs that, nonetheless, has found a way to get through. ...Read more
Congenital defect: Tetralogy of fallot is a congenital defect of the heart in which the there is a hole in the ventricular septum (wall that separate the two ventricles) of the heart, overriding of the septal defect by the aorta and atresia of the pulmonary artery, it causes mixing of arterial blood with venous blood, therefore hypoxemia (low level of oxygen) to the general circulation, pulmonary HTN may occur. ...Read more
Artery vs vein: Arteries take blood away from the heart (right ventricle in this case) and veins return blood to the heart (pulmonary veins drain into the left atrium). ...Read more
What are the names of the valves that separate the ventricles from the aorta and the pulmonary artery?
Valves: Those are the aortic valve and the pulmonary valve. ...Read more
Terminology: Pulmonary artery disease is a vague term that may relate to any abnormal process in the pulmonary arterial system, however, pulmonary arterial hypertension is a very specific disorder that is defined by an elevated mean pulmonary arterial pressure, a normal wedge pressure, and an elevated pulmonary vascular resistance. These are measured by doing a right heart catherization. ...Read more
Would my husbands symptoms after a saddle embolism of pulmonary artery have been different if it were treated earlier?
My echo showed normal heart and pulmonary artery pressures normal at 25-30mmoh isn't this too high?
Is it ok if the pulmonic valve and the pulmonary artery were not well visualized in my echocardiogram if I had an abnormal ecg?

PDA: Patent ductus.Get a more detailed answer ›
Is there difference between pulmonary artery hypertension and RVSP? If so, is there difference in severity? My echo showed RVSP42.57 mmHg, why?
Yes. Need expert.: RVSP is a sign- or rather a calculation based on an echocardiogram. By itself, it doesn't mean anything. PAH is a medical condition characterized by high pressures in the pulmonary vessels. While symptom severity correlates with pressr, RVSP is calculated (estimated) & not directly measured. PAH is diagnosed based on symptoms & pressure readings on right heart catheterization. Use HealthTap Prime. ...Read more

PDA: A patent (open) ductus (vessel) arteriosis (between 2arteries). This opening is normal and usually closes with the first breath or two in a newborn. If it doesn't close, sometimes it needs to be tied off surgically. ...Read more
Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?
Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read more
