  2. Persistent fetal circulation - Wikipedia

    en.wikipedia.org/wiki/Persistent_fetal_circulation

    The failure of the circulatory system of the newborn to adapt to these changes by lowering PVR leads to persistent fetal circulation. [2] The newborn is therefore born with elevated PVR, which leads to pulmonary hypertension. Because of this, the condition is also widely known as persistent pulmonary hypertension of the newborn (PPHN). [3]

  3. Pulmonary hypertension - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_hypertension

    In terms of the diagnosis of pulmonary hypertension, it has five major types, and a series of tests must be performed to distinguish pulmonary arterial hypertension from venous, hypoxic, thromboembolic, or unclear multifactorial varieties. PAH is diagnosed after exclusion of other possible causes of pulmonary hypertension. [15]

  4. Pulmonary arterial hypertension - Wikipedia

    en.wikipedia.org/.../Pulmonary_arterial_hypertension

    A pulmonary artery wedge pressure being less than 15 mmHg (also measured by right heart catheterization) excludes post-capillary bed (in the veins distal to the capillary bed) pulmonary hypertension. Pulmonary arterial hypertension is a subgroup of pulmonary hypertension and is categorized as World Health Organization as group 1. [3]

  5. Persistent truncus arteriosus - Wikipedia

    en.wikipedia.org/wiki/Persistent_Truncus_Arteriosus

    Persistent truncus arteriosus (PTA), [1] often referred to simply as truncus arteriosus, [2] is a rare form of congenital heart disease that presents at birth. In this condition, the embryological structure known as the truncus arteriosus fails to properly divide into the pulmonary trunk and aorta.

  6. Respiratory disease - Wikipedia

    en.wikipedia.org/wiki/Respiratory_disease

    Persistent Pulmonary Hypertension of the Newborn (PPHN) is a syndrome that occurs from an abnormal transition to extra-uterine life. It is marked by an elevated pulmonary vascular resistance and vasoconstriction causing a right-to-left shunt of the blood through the foramen ovale or ductus arteriosus. [9]

  7. Right ventricular hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Right_ventricular_hypertrophy

    Since the main causes of right ventricular hypertrophy is tricuspid regurgitation or pulmonary hypertension (discussed above), management involves treatment of these conditions. [3] Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [ 12 ]
