My echo showed normal heart and pulmonary artery pressures normal at 25-30mmoh isn't this too high?

My echo showed normal heart and pulmonary artery pressures normal at 25-30mmoh isn't this too high?

Probably ok: The best person to review the echo findings with is the doctor who ordered the test. The diagnostic gold standard for PAH is right heart catherterization.

Artery (Definition)

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

What does this mean Other Anomalies Of Pulmonary Artery And Pulmonary Circulation with collateral flow?

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.

What does this mean: ascending aorta at the level of the pulmonary artery bifurcation measures 2.5 x 2.3cm ap and transverse? Is this too big?

What does this mean: ascending aorta at the level of the pulmonary artery bifurcation measures 2.5 x 2.3cm ap and transverse? Is this too big?

Not too big.: When is the ascending aorta too big? Depends on the aortic valve, how fast it is growing, underlying connective tissue disorder, symptoms, size of the patient, and, of corse, size of the aorta. Two and a half centimeters is not too big though.

Pulmonary artery catheter - what does it mean if it doens't hurt the heart valves?

Pulmonary artery catheter - what does it mean if it doens't hurt the heart valves?

Correct: Catheter floats through the valves and doesn't penetrate the heart or valves think like a floater at the end of a string and float it through a tunnel with running water same effect.

What's a pulmonary artery catheter used for?

What's a pulmonary artery catheter used for?

Cardiac function: The PA catheter is used to measure pressures in the pulmonary circulation and measure cardiac output. Both are critical informations needed to assess cardiac function in critically sick patients and guide therapy.

How does pulmonary artery differ from the vena cava?

How does pulmonary artery differ from the vena cava?

Anatomy lesson: The pulmonary artery is the vessel that carries blood from the right ventricle to the lungs where the blood is oxygenated. The vena cava are veins that drain blood into the right atrium from both the upper and lower halves of the body.

Is it dangerous to have an enlarged pulmonary artery?

Is it dangerous to have an enlarged pulmonary artery?

May be a sign of...: An enlarged pulmonary artery may indicate pulmonary arterial hyper tension. A work up should be done to investigate. A 2d-echo, ct scan, possible sleep study....

How is the pulmonary artery pressure different from other arteries?

How is the pulmonary artery pressure different from other arteries?

Different: The pulmonary and systemic circulations are different & therefore have different bps with pulmonary system being a lower pressure system.

How to differentiate between a central line and a pulmonary artery catheter?

How to differentiate between a central line and a pulmonary artery catheter?

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.

What's the difference between a central line and a pulmonary artery catheter?

Lines: A central line generally ends in the right atrium and a pulmonary artery line ends in the main pulmonary artery

Why does a PDA not occur in the right branch of the pulmonary artery?

Why does a PDA not occur in the right branch of the pulmonary artery?

PDA: It occurs between descending thoracic aorta and PA. The descending thor aorta is well to the left of the right branch of the PA. I couldn't find a variant reported in the literature with involvement of the right PA branch. There may be an embryologic explanation but I didn't find it.

Please explain why PDA does not occur in right branch of pulmonary artery?

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.

Can a pulmonary artery rupture be fatal?

Can a pulmonary artery rupture be fatal?

Rupture PA fatal: The pulmonary artery is large, with pressure lower than systemic pressure. So, yes a rupture, tear, of laceration in the pulmonary artery (or one of its many branches) can be lethal; blood loss, not easy to control, or compress.

Tetrology of fallot with pulmonary artery?

Tetrology of fallot with pulmonary artery?

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.

How does one know if one has a ruptured pulmonary artery?

How does one know if one has a ruptured pulmonary artery?

One is dead: A ruptured pa is one of the fastest ways to die. I wouldn't worry about it. If you're coughing up blood, and it's not from a nosebleed, that's a medical urgency if not emergency, but it's probably not a pa rupture.
