Vorticity for the assessment of pulmonary vascular hemodynamics in pulmonary arterial hypertension
نویسندگان
چکیده
Background 4D flow CMR analysis of main pulmonary artery (MPA) flow in pulmonary arterial hypertension (PAH) has demonstrated vortical formations whose existence time correlates with mean pulmonary arterial pressure (MPAP). Vorticity can quantitate the rotation of these vortices and may represent a novel way to assess pulmonary arterial hemodynamics. We aimed to determine if MPA vorticity correlates with pulmonary vascular hemodynamics in PAH subjects when compared to controls using 4D flow CMR.

Effect of thoracic epidural blockade on hypoxia-induced pulmonary arterial hypertension in rats
Objective(s): The present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. Materials and Methods: Forty eight Wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. Animals were placed in a hypoxia chamber and instrumented with epidural catheters at the t...
متن کاملArrhythmias in Patients With Pulmonary Hypertension; A Narrative Review of the Current Literature
Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

Background: Pulmonary Arterial Hypertension (PAH), a fatal orphan disease, is defined as increased mean Pulmonary Arterial Pressure (mPAP) above 25 mm/Hg, Pulmonary Capillary Wedge Pressure (PCWP) below 15 mm/Hg, and pulmonary vascular Resistance over 3 Wood Unit (WU). Although Pulmonary Hypertension (PH) is a relatively prevalent disease, the idiopathic form (iPAH) is a rare disease with a pre...

The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
متن کاملA case of severe pulmonary hypertension associated with common arterial trunk and VSD in a 9 years old child
Background: Common arterial trunk (CAT) is a rare congenital heart disease, and often leads to the early development of pulmonary hypertension and disability. Among the critical structural heart defects, the frequency of CAT is 3%, which reflects the severe hemodynamic disturbances. The natural course of the disease is characterized by a high mortality rate up to 88% during the first year of li...
