Aortic valve

aorticaortic valvesaortic semilunar valve
Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery.
It is one of the two semilunar valves of the heart, the other being the pulmonary valve.

Ventricle (heart)

ventricleleft ventricleright ventricle
The pulmonary valve (sometimes referred to as the pulmonic valve) is the semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps.
The right ventricle receives deoxygenated blood from the right atrium via the tricuspid valve and pumps it into the pulmonary artery via the pulmonary valve, into the pulmonary circulation.

Heart valve

The pulmonary valve (sometimes referred to as the pulmonic valve) is the semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps.
The two semilunar (SL) valves, the aortic valve and the pulmonary valve, which are in the arteries leaving the heart.

Infundibulum (heart)

*At the apex of the infundibulum, the pulmonary orifice is guarded by three semilunar cusps - two in front and one behind, with free edges projecting upward into the lumen of pulmonary trunk.

Valvular heart disease

heart valve diseasecardiac valve diseasevalve disease
Valvular heart disease is any disease process involving one or more of the four valves of the heart (the aortic and bicuspid valves on the left side of heart and the pulmonary and tricuspid valves on the right side of heart).

Pulmonary insufficiency

pulmonary regurgitationpulmonary valve insufficiencyPulmonary valve regurgitation
Pulmonary insufficiency (or incompetence, or regurgitation) is a condition in which the pulmonary valve is incompetent and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole.

Pulmonary atresia

failure to from the pulmonary artery valve
Pulmonary atresia is a congenital malformation of the pulmonary valve in which the valve orifice fails to develop.

Cardiac physiology

cardiac function cardiacArmy Cardiac Center
The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation where carbon dioxide can be exchanged for oxygen in the lungs.

Pulmonary valve stenosis

pulmonic stenosisCongenital Pulmonary Stenosispulmonary valvular stenosis
Blood going from the heart to the lungs goes through the pulmonary valve, whose purpose is to prevent blood from flowing back to the heart.

Systole

systolicsystolic pressureventricular systole
The second stage proceeds immediately, pumping oxygenated blood from the left ventricle through the aortic valve and aorta to all body systems, and simultaneously pumping oxygen-poor blood from the right ventricle through the pulmonic valve and pulmonary artery to the lungs.

Cardiac fibrosis

myocardial fibrosiscardiac valvulopathycardiac
When over-activated this process causes thickening and fibrosis of the valve, with white tissue building up primarily on the tricuspid valve, but also occurring on the pulmonary valve.

Tetralogy of Fallot

The procedure involves increasing the size of the pulmonary valve and pulmonary arteries and repairing the ventricular septal defect.

Ross procedure

The Ross procedure (or pulmonary autograft) is a cardiac surgery operation where a diseased aortic valve is replaced with the person's own pulmonary valve.

Absent pulmonary valve syndrome

Absent pulmonary valve syndrome (also called congenital absence of the pulmonary valve) is a congenital heart defect that occurs when the flaps of the pulmonary valve do not develop or are severely underdeveloped (hypoplasia) resulting in aneurysms (dilation) of the pulmonary arteries and softening of the trachea and bronchi (tracheobronchomalacia).

A right ventricular outflow tract obstruction (RVOTO) may be due to a defect in the pulmonic valve, the supravalvar region, the infundibulum, or the pulmonary artery.

The pressure in the ventricles must be greater than the systemic and pulmonary pressure to open the aortic and pulmonic valves, respectively.
