Parameters of Right Ventricular Function Reveal Ventricular-Vascular Mismatch as Determined by Right Ventricular Stroke Work versus Pulmonary Vascular Resistance in Children with Pulmonary Hypertension

Right ventricular (RV) failure, a determinant of outcomes in pulmonary hypertension (PH), occurs when the right ventricle cannot compensate for increased afterload. The authors showed that RV stroke work (RVSW) can be estimated in children with PH as the product of stroke volume and RV pressure and is related to adverse outcomes. The aim of this study was to test the hypothesis that ventricular-vascular (VV) mismatch (high afterload and low RVSW) is associated with echocardiographic measures of RV performance and adverse outcomes.

Authors: Toroghi HM, Lo KB, Ziccardi MR, Horn B, Kanjanahattakij N, Malik E, Penalver J, Rangaswami J, Gupta S, Amanullah A Abstract Worsening renal function in patients with heart failure with preserved ejection fraction is associated with poor outcomes. Pulmonary arterial capacitance is a novel right heart catheterization derived hemodynamic metric representing pulmonary arterial tree distensibility and right ventricle afterload. Given the strong association between heart failure, pulmonary hypertension, and kidney function, the goal of this study is to investigate the correlation between Pulmonary arterial capac...

KhanAbstractBackgroundIn-hospital respiratory outcomes of non-surgical patients with undiagnosed obstructive sleep apnea (OSA), particularly those with significant comorbidities are not well defined. Undiagnosed and untreated OSA may be associated with increased cardiopulmonary morbidity.Study objectivesEvaluate respiratory failure outcomes in patients identified as at-risk for OSA by the Berlin Questionnaire (BQ).MethodsThis was a retros...

AbstractAimsRemodelling of the extracellular matrix (ECM) is a key mechanism involved in the development and progression of heart failure (HF) but also functional in associated pulmonary hypertension (PH). Our aim was to identify plasma ECM proteins associated to end ‐stage HF and secondary PH in relation to haemodynamics, before and after heart transplantation (HT).Methods and resultsTwenty ECM plasma proteins were analysed with proximity extension assay in 20 controls and 26 HF patients pre ‐HT and 1 year post‐HT. Right heart catherization haemodynamics were assessed in the patients during the preoperative evaluati...

We thank Wang et al. for their comments and for bringing forward the challenges in managing care of patients with pulmonary hypertension (PH) and stroke. We acknowledge multiple possible mechanisms of stroke in patients with PH, and we highlighted them in our work, including paradoxical emboli and atrial fibrillation [1]. However, polycythemia (increased red cells) or other myeloproliferative disorders are considered to be a cause and not a consequence of PH [2,3]. In mice models, Sala et al. have showed that chronic hypoxia could lead to both PH and polycythemia [4].

Abstract Pulmonary endarterectomy is a curative procedure for chronic thromboembolic Pulmonary Hypertension. As usual, cardiopulmonary bypass circuit is required. However, there are several complications attributed to extracorporeal circulation. Hemodilution, systemic inflammatory response syndrome and leukocyte sequestration are circulation related complications. The severe forms include Acute Respiratory Distress Syndrome, Acute Lung Injury, myocardial stunning, dysfunction of the right ventricle, coagulopathy, postoperative stroke or renal dysfunction. In this case report, we aimed to give information about perioperativ...
