Background: precapillary pulmonary hypertension (PH, PcPH) is now defined as a mean pulmonary artery pressure (mPAP) > 20 mmHg, a pulmonary artery wedge pressure (PAWP) ≤ 15 mmHg and a pulmonary vascular resistance (PVR) > 2 WU. For PVR calculation, the measurement of cardiac output (CO) is necessar...
Pulmonary tumor embolism is characterized by the occlusion of pulmonary vessels by tumor clots, which can be found in the proximal arteries (macro-embolism) or the small vessels (micro-embolism). The clinical presentation is mainly a progressive dyspnea associated with pulmonary hypertension and sub...
The contribution of exercise echocardiography in primary asymptomatic mitral regurgitation (MR) remains debated. The aim of this study was to gain evidence regarding its usefulness in this setting and to investigate the prognostic value of peak exercise systolic pulmonary artery pressure (SPAP). One...
Doppler echocardiography is widely used in everyday clinical practice for the detection of pulmonary hypertension (PH) in symptomatic patients and in populations particularly at risk of pulmonary arterial hypertension (PAH). It allows accurate estimation of systolic pulmonary arterial pressure but m...
Subclinical hypothyroidism has been associated with heart failure, but only small trials assessed whether treatment with levothyroxine has an impact on cardiac function. In a randomized, double-blind, placebo-controlled, trial nested within the TRUST trial, Swiss participants ages ≥65 years with sub...
The aim of this study was to evaluate the pathophysiological role and the prognostic significance of pulmonary artery compliance (C PA ), a measure of right ventricular pulsatile afterload, in cardiogenic shock. We retrospectively included 91 consecutive patients with cardiogenic shock due to primar...
A 5-year-old girl presented with acute nocturnal episodes of loss of consciousness following abdominal pain and crying. Epilepsy was primarily diagnosed but the course of the disease was suggestive of pulmonary hypertension. An adapted invasive assessment of pulmonary pressure and pharmacological ch...
Complications following lung transplantation may impede allograft function and threaten patient survival. The five main complications after lung transplantation are primary graft dysfunction, post-surgical complications, alloimmune responses, infections, and malignancy. Primary graft dysfunction, a...
Μελετήθηκαν οι αλλοιώσεις δέκα σκύλων με βαριάς μορφής χρόνια διροφιλαρίωση. Στον πνεύμονα, οι εντονότερες αλλοιώσεις παρατηρήθηκαν στο ενδαρτήριο των κλάδων της πνευμονικής αρτηρίας. Επίσης, σημαντικές ήταν οι αγγειακές θρομβώσεις, αλλά και η κοκκιωματώδης αντίδραση του πνευμονικού παρεγχύματος. Η...
Electrical impedance tomography (EIT) shows potential for radiation-free and noninvasive hemodynamic monitoring. However, many factors degrade the accuracy and repeatability of these measurements. Our goal is to estimate the impact of this variability on the EIT-based monitoring of two important cen...
javax.xml.bind.JAXBElement@6f8948ff Hypoxia represents both an outcome of cardiopulmonary diseases and a trigger for severe pulmonary complications as pulmonary hypertension. Because nitric oxide (NO) is a critical mediator in the development of pulmonary hypertension, the modulators of its downstre...
Introduction : Dès la fin du 20e siècle, un nombre grandissant de pathologies cardiaques sont traitées par voie endovasculaire. En effet, cette nouvelle technique comporte une efficacité similaire à la chirurgie avec un taux de complications moindre. Malgré tout, cette approche présente des complica...
Introduction Quelles soient congénitales ou post-chirurgicales, les sténoses de l’artère pulmonaire font partie des pathologies qui, de nos jours, profitent le plus du traitement par cathétérisme cardiaque. L’évolution technique et l’expérience médicale acquises ces dernières années en font aujourd’...
Pulmonary artery sling (PAS) is a rare congenital condition in which the left pulmonary artery (LPA) arises from the right pulmonary artery, and then passes between the trachea and the esophagus to reach the left lung, thereby forming a sling around the airway. It is often associated with intrinsic...
Pulmonary hypertension (PH) is diagnosed using cardiac catheterization and is defined as an elevation of mean pulmonary artery pressure (PAP) greater than 25 mmHg. Although invasive hemodynamics remains the gold standard and is mandatory for disease confirmation, transthoracic echocardiography (TTE)...
The heart is a dual pump. The right side receives blood from the body into the right atrium. From this chamber it passes to the right ventricle, a muscular pump capable of driving the de-oxygenated blood through the lungs via the pulmonary artery. Freshly-oxygenated blood returns to the left side of...
Objectives: To evaluate the use of non-ECG-gated computed tomography ă (CT) angiography to describe pulmonary and coronary defects in patients ă with tetralogy of Fallot (TOF). ă Patients and methods: This retrospective study was carried out on TOF ă patients having undergone pre-operative non-ECG-g...
