Valvular disorders can arise from the pulmonary valve Pulmonary valve A valve situated at the entrance to the pulmonary trunk from the right ventricle. Heart: Anatomy, located between the right ventricle (RV) and the pulmonary artery Pulmonary artery The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs. Lungs: Anatomy (PA). Valvular disorders are diagnosed by echocardiography Echocardiography Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic. Tricuspid Valve Atresia (TVA). Pulmonary stenosis Stenosis Hypoplastic Left Heart Syndrome (HLHS) ( PS PS Invasive Mechanical Ventilation) is valvular narrowing causing RV outflow tract obstruction. Patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship are often asymptomatic unless they have other congenital Congenital Chorioretinitis cardiac anomalies or severe PS PS Invasive Mechanical Ventilation. Symptoms (exertional dyspnea Dyspnea Dyspnea is the subjective sensation of breathing discomfort. Dyspnea is a normal manifestation of heavy physical or psychological exertion, but also may be caused by underlying conditions (both pulmonary and extrapulmonary). Dyspnea, chest pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways, and syncope Syncope Syncope is a short-term loss of consciousness and loss of postural stability followed by spontaneous return of consciousness to the previous neurologic baseline without the need for resuscitation. The condition is caused by transient interruption of cerebral blood flow that may be benign or related to a underlying life-threatening condition. Syncope) are due to RV failure. Severe PS PS Invasive Mechanical Ventilation is treated surgically.

Pulmonary (or pulmonic) valve:
|Pulmonary stenosis Stenosis Hypoplastic Left Heart Syndrome (HLHS) ( PS PS Invasive Mechanical Ventilation)||Pulmonary regurgitation Pulmonary regurgitation Backflow of blood from the pulmonary artery into the right ventricle due to imperfect closure of the pulmonary valve. Pulmonary Regurgitation (PR)|
|Etiology||Mostly congenital Congenital Chorioretinitis||Mostly acquired|
|Murmur||Systolic murmur, left upper sternal border (preceded by a systolic click that decreases with inspiration Inspiration Ventilation: Mechanics of Breathing)||Diastolic murmur, left upper sternal border, increases with inspiration Inspiration Ventilation: Mechanics of Breathing|
|S2 S2 Heart Sounds||Split S2 S2 Heart Sounds with soft and delayed P2||Split S2 S2 Heart Sounds with a loud P2|
|Echocardiographic findings||Thick and domed leaflets, with increased systolic velocity across the valve, RVH||Valvular abnormalities (depending on etiology), RV enlargement, and a regurgitant jet in the right ventricular outflow tract|
Pulmonary stenosis Stenosis Hypoplastic Left Heart Syndrome (HLHS) is the narrowing of the pulmonary valve Pulmonary valve A valve situated at the entrance to the pulmonary trunk from the right ventricle. Heart: Anatomy causing:
