A 3-month-old infant with perimembranous ventricular septal defect (VSD) and pulmonary hypertension presented at our center. Cardiac catheterization showed a systolic pulmonary-to-systemic arterial pressure ratio of 0.99 and a pulmonary vascular resistance of 9.32 μm(2). Pulmonary angiography showed focal orifice stenosis in the right lower and left lower and upper pulmonary veins, whereas the right upper pulmonary vein was atretic. Sutureless pericardial marsupialization concomitant with VSD patch closure was used to repair the three stenotic veins. Administration of home oxygen therapy and sildenafil citrate was continued after surgical repair. Postoperative catheterization 1.5 years after surgery showed patency of the three repaired veins and normalization of pulmonary vascular resistance.

The Fontan operation results in a circulation that is dependent on low pulmonary vascular resistance to maintain an adequate cardiac output. Medical therapies that lower pulmonary vascular resistance ...
There has been suggestion that a greater "pulmonary vascular reserve" defined by a low pulmonary vascular resistance (PVR) and a high lung diffusing capacity (DL) allows for a superior aerobic exercis...
Pulmonary hypertension (PH) exists when mean pulmonary artery pressure (mPAP) is 25 mm Hg or greater. mPAP of 35 mm Hg or greater, with increased pulmonary vascular resistance from portopulmonary hype...
To evaluate the effects of endothelin inhibitors (ERAs) on hemodynamic and functional parameters in patients post-Fontan procedure with high pulmonary vascular resistance (PVR).
Persistent pulmonary hypertension of the newborn (PPHN) is characterized by elevated pulmonary vascular resistance. Endogenous nitric oxide is critical for regulation of pulmonary vascular resistance....
Clinical evidence reveals that some patients who undergo cardiac transplantation exhibit problems with pulmonary vascular resistance as well. In some studies, an increase in pulmonary vas...
Pulmonary arterial hypertension (PAH) in patients with congenital heart disease usually develops secondary to chronic volume overload of the pulmonary circulation following left to right s...
Pulmonary hypertension (PH) is a consequence of an increase in pulmonary vascular resistance (PVR), pulmonary blood flow, pulmonary venous pressure, or a combination of these elements. Pul...
In summary, the investigators propose to integrate fMRI assessments within a clinical trial of quetiapine XR in patients with melancholic depression in order to test the predictions that: ...
Pulmonary embolism (PE) is a serious disease with frequent intra hospital mortality remains high. If anticoagulation is perfectly codified, the remainder of the initial management has been...
The active alterations of vascular wall structures, often leading to elevated VASCULAR RESISTANCE. It is associated with AGING; ATHEROSCLEROSIS; DIABETES MELLITUS; HYPERTENSION; PREGNANCY; PULMONARY HYPERTENSION; and STROKE, but is also a normal part of EMBRYOGENESIS.
Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.
The vascular resistance to the flow of BLOOD through the CAPILLARIES portions of the peripheral vascular bed.
A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
Pathological process resulting in the fibrous obstruction of the small- and medium-sized PULMONARY VEINS and PULMONARY HYPERTENSION. Veno-occlusion can arise from fibrous proliferation of the VASCULAR INTIMA and VASCULAR MEDIA; THROMBOSIS; or a combination of both.

Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Pulmonary arterial hypertension (PAH) is a chronic, life-threatening disorder characterized by abnormally high blood pressure in the arteries between the heart and lungs of affected individuals. Symptoms can range from mild breathles...
