Pulmonary artery

ventricular septal defects, narrowed valves leading to the pulmonary artery, and a thickened right ventricle. The shunt is from right-to-left because blood flow is obstructed due to pulmonary stenosis and right ventricle hypertrophy. This causes decreased venous return to the heart and low pressure from peripheral veins. Poor movement of oxygen in the blood

towards the atrium this helps with pumping the deoxygenated blood to the pulmonary artery. The pulmonary artery is a large blood vessel, the are two veins for each lungs the blood pumping through the pulmonary artery is brought into the lungs where the deoxygenated blood is altered and oxygen is added turning the blood into oxygenated blood, from there it proceeds into the left side of the heart travelling through the pulmonary vein (one of the only veins that carries oxygenated blood) to the mitral

Sildenafil, a phosphodiesterase type 5 inhibitor, is used to treat patients with pulmonary hypertension. The objective of the study was to evaluate the efficacy and tolerability of 3 different doses of sildenafil. The clinical importance of this study was to determine which dose of sildenafil was most effective in patients with pulmonary hypertension. The study was a double blind, placebo-controlled study performed between October 2002 and November 2003. The study was conducted in 53 centers

side of the heart appeared slightly bigger than the right side. The atria looked like flaps and were very flimsy compared to the ventricles. The ventricles appeared light pink in colour and were very big, taking up a lot of space in the heart. The arteries were identified, but the veins were not. A finger could be placed down the aorta. Internal Observation Inside the heart the four chambers were clearly defined and hollow. The wall on the left side of the heart was much thicker and firmer than

Eisenmenger Syndrome is a congenital heart defect that is associated with long-term elevated blood flow through the pulmonary vasculature, which tends to cause pulmonary hypertension and increasing pulmonary vascular resistance (D 'Alto, 2014). Moreover, this is a heart defect that causes a hole to develop between two chambers of the heart (D’Alto, 2014). The hole causes blood to circulate abnormally in the heart and lungs. Increased blood flow returns to your lungs instead of going to the rest of

usually cause none to few problems. Medium and large defects can cause more severe problems. These range from mild to life threatening complications. Pulmonary hypertension can last for years or a lifetime. It is a type of high blood pressure that affects arteries in the lungs and heart. It increases the blood flow to the lungs, affecting the lung arteries, which can cause them to become permanently damaged. This complication can cause the reversal of blood flow through the hole, which is Eisenmenger

The pulmonary valve is one of the semi lunar valve next to aortic valve, lying between the right ventricle and the Pulmonary artery which takes deoxygenated blood from the body and pumps it into the heart. Generally tricuspid, the pulmonary valve is considered simpler in anatomical sense. A semi lunar valve separates a ventricle from a blood vessel which the ventricle leads into in its flow path of blood. The absence of chordae tendinae is prominent in the semilunar valves. The pulmonary leaflets

Compassionate, loving and bright are only some of the words that can describe Stephanie. Born on March 22, 1995 in the small city of El Paso, Texas where her mom and I met, she was the very first-born out of four children. Her along with her younger siblings, became military brats and so we traveled to many places like Europe, Hawaii and all across the U.S. Then we made our last stop in El Paso even though we stopped there, her love for travel never seem to go away. As a result Steph didn’t want

Galie’s et al. compared the six-minute walk distance (6-MWD) in patients twelve years or older with symptomatic pulmonary arterial hypertension (PAH) who took placebo versus 4 doses of oral tadalafil with or without bosentan. This multi-center, double-blind, placebo-controlled, randomized controlled study lasted 16 weeks. The patients were placed into 5 different groups: tadalafil 2.5mg, 10mg, 20mg, 40mg, or placebo once daily, and stratification was based on walking distance of 325m, type of PAH
