Reappraisal of the Transthoracic Echocardiographic Algorithm in Predicting Pulmonary Hypertension Redefined by Updated Pulmonary Artery Mean Pressure Threshold

open access: yesAnatolian Journal of Cardiology, 2023
Background: Although an adopted echocardiography algorithm based on tricuspid regurgitation jet peak velocity and suggestive findings for pulmonary hypertension has been utilized in the non-invasive prediction of pulmonary hypertension probability, the ...

Hidden pulmonary arteries in tetralogy of Fallot and pulmonary artery pressure in patients operated with a pulmonary artery [PDF]

open access: yesBMC Cardiovascular Disorders, 2021
Abstract Introduction The absence of a pulmonary artery is a rare congenital anomaly that occurs isolated or with other congenital cardiac disorders, particularly tetralogy of Fallot (TOF); meanwhile, a hidden pulmonary artery might exist and originate from a closed ductus arteriosus (DA), which can be stented to reach ...

Estimation of Pulmonary Arterial Pressure Using Simulated Non-Invasive Measurements and Gradient-Based Optimization Techniques

open access: yesMathematical and Computational Applications, 2022
Reliable quantification of pulmonary arterial pressure is essential in the diagnostic and prognostic assessment of a range of cardiovascular pathologies, including rheumatic heart disease, yet an accurate and routinely available method for its ...

Hemodynamic trajectories and outcomes in patients with pulmonary arterial hypertension

open access: yesPulmonary Circulation, 2020
The relative pulmonary to systemic pressure ratio (mean pulmonary arterial pressure/mean arterial pressure) has been proven to be valuable in cardiac surgery.

The isobaric pulmonary arterial compliance in pulmonary hypertension

open access: yesERJ Open Research, 2021
Pulmonary hypertension is associated with stiffening of pulmonary arteries which increases right ventricular pulsatile loading. High pulmonary artery wedge pressure (PAWP) in postcapillary pulmonary hypertension (Pc-PH) further decreases pulmonary ...

A multiscale model of vascular function in chronic thromboembolic pulmonary hypertension [PDF]

open access: yes, 2021
Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by recurrent or unresolved pulmonary thromboemboli, leading to perfusion defects and increased arterial wave reflections. CTEPH treatment aims to reduce pulmonary arterial pressure and reestablish adequate lung perfusion, yet patients with distal lesions are inoperable by standard surgical

Pulmonary arterial pulse pressure and mortality in pulmonary arterial hypertension [PDF]

open access: yesRespiratory Medicine, 2007
In the Framingham studies, systemic arterial pulse pressure correlated linearly with morbidity and mortality. Right ventricular (RV) systolic dysfunction and pulmonary circulation stiffening result in abnormalities of pulmonary arterial (PA) pulse pressure in PA hypertension (PAH).

Left atrial unloading with an 8 mm septal cutting balloon to treat postcapillary pulmonary hypertension: a case report

open access: yesESC Heart Failure, 2022
We report the case of a 58‐year‐old female with severe postcapillary pulmonary hypertension (averaged mean pulmonary arterial pressure was 49 mmHg, pulmonary arterial wedge pressure 29 mmHg, and right atrial pressure 8 mmHg) due to heart failure with ...

Impact of the updated hemodynamic definitions on diagnosis rates of pulmonary hypertension

open access: yesPulmonary Circulation, 2020
We evaluated whether updated pulmonary hypertension definitive criteria proposed in sixth World Symposium on Pulmonary Hypertension had an impact on diagnosis of overall pulmonary hypertension and pre-capillary and combined pre- and post-capillary ...

Study of the Relationship between Pulmonary Artery Pressure and Heart Valve Vibration Sound Based on Mock Loop

open access: yesBioengineering, 2023
The vibration of the heart valves’ closure is an important component of the heart sound and contains important information about the mechanical activity of a heart.
