Effect of Milrinone Infusion on Pulmonary Vasculature and Stroke Work Indices: A Single-Center Retrospective Analysis in 69 Patients Awaiting Cardiac Transplantation
ConclusionMilrinone improved left ventricular stroke work indices to a greater extent than right ventricular stroke work indices and had beneficial effects on right ventricular net input impedance, predominantly via augmentation of left ventricular stroke volume and passive unloading of the pulmonary circuit. Patients who had the worst biventricular performance benefited the most from chronic milrinone infusion.

RV stroke work in children with pulmonary arterial hypertension: estimation based on invasive haemodynamic assessment and correlation with outcomes
Conclusions RVSW can be estimated in children with PAH, and is significantly associated with abnormal WHO class, the need for septostomy, as well as mortality. Indices accounting for RV performance as well as ventricular-vascular coupling may be useful in the prognosis and, hence, management of children with PAH.

Systemic blood pressure in severe aortic stenosis: Haemodynamic correlates and long ‐term prognostic impact
ConclusionsIn severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.

Acute absolute vasodilatation is associated with a lower vascular wall stiffness in pulmonary arterial hypertension
Abstract: Background: Acute vasoreactivity testing (VT) is considered mandatory in the diagnostic work-up of patients with pulmonary arterial hypertension (PAH). We studied the relation between the acute absolute arterial vasodilatation and the severity of vascular remodeling estimated by intravascular ultrasound (IVUS) in patients with idiopathic PAH.Methods: Simultaneous right heart catheterization and IVUS of the pulmonary artery (PA) were performed both in basal conditions and during short-term intravenous epoprostenol infusion in nineteen idiopathic PAH patients. Pulmonary vascular resistance (PVRi) and capacitance in...

Relationship of Right- to Left-Sided Ventricular Filling Pressures in Advanced Heart Failure: Insights From the ESCAPE Trial Original Articles
Conclusions— Increased RAP/PCWP ratio was associated with higher pulmonary vascular resistance, reduced RV function (manifest as a larger right atrium and ventricle and lower RV stroke work index), and an increased risk of adverse outcomes in patients with advanced heart failure.

Abstract P104: Oxygen Drastically Increases Cardiac Output Without Changing Mean Pulmonary Arterial Pressure in a Patient With Severe, Progressive Pulmonary Hypertension Session Title: Onsite Poster Competition I With Reception
Conclusion: Our patient had no significant change in mPAP facing oxygen-induced decrease in PVR. Instead, there was a marked increase in RV CO explainable only by an increase in RV SV facing decreased RV afterload, as HR decreased with oxygen. These findings are consistent with the patient’s class 1 exercise capacity despite having severe PH, indicating an ability to increase CO with activity and suggesting a positive response to medications and better prognosis. Our case shows the importance of assessing hemodynamic data in the workup and management of PH. We propose using TTE assessment of CO coupled with 100% oxygen a...

Vascular plugging for the enlarging pulmonary arteriovenous malformation in a patient with idiopathic pulmonary artery hypertension
Publication date: Available online 2 March 2018 Source:Canadian Journal of Cardiology Author(s): Kae-Woei Liang, Chi-Yao Huang, Sheng-Ling Jan, Kuo-Yang Wang The coexistence of idiopathic pulmonary artery hypertension (IPAH) with pulmonary arteriovenous malformation (PAVM) is challenging because while the PAVM causes hypoxia and polycythemia with potential thrombotic complications, closing the PAVM increases pulmonary-artery pressure. Here, we report on a lady with PAVM and IPAH who, within two years of diagnosis, had an ischemic stroke, PAVM enlargement from 20x20x30 mm to 30x40x40 mm and oximetry decrease to 90%. Trans-...

Clinical Correlates and Prognostic Value of Elevated Right Atrial Pressure in Patients With Hypertrophic Cardiomyopathy.
CONCLUSIONS: Elevated RAP in patients with HCM is associated with left-sided heart failure and is an independent predictor of all-cause mortality and new-onset AF. PMID: 29526913 [PubMed - as supplied by publisher]

Effects of Riociguat on Right Ventricular Remodelling in Chronic Thromboembolic Pulmonary Hypertension Patients: A Prospective Study
ConclusionsRiociguat treatment was associated with increased RV stroke volume index and trends for improvement in myocardial remodelling in patients with CTEPH. A larger clinical study is warranted to observe the therapeutic benefits of riociguat on RV remodelling.RésuméContexteLes effets du traitement par le riociguat sur le métabolisme, la perfusion et le débit du ventricule droit (VD) chez les patients atteints d’hypertension pulmonaire thromboembolique chronique (HPTC) sont inconnus. Dans la présente étude, nous analysons les changements aux ventriculaires droits associés au traitement par le riociguat.Méthod...

Initiation of ivabradine in cardiogenic shock
ConclusionsIn our small non ‐randomized series of patients in cardiogenic shock, ivabradine was safely used to reduce HR in patients previously intolerant of beta‐blockade. There are limited data surrounding the use of ivabradine in cardiogenic shock, and future studies should be undertaken to determine the optimal HR in h umans with cardiogenic shock and whether systematic limitation of peak HR may improve outcomes.

Healthy Aging and Cardiovascular Function: Invasive Hemodynamics During Rest and Exercise in 104 Healthy Volunteers
ConclusionsThe age-related decline in exercise capacity among healthy persons is due predominantly to cardiac mechanisms, including reduced chronotropic and inotropic reserve and possibly reduced Frank-Starling reserve. Peak exercise left ventricular filling pressure and arteriovenous oxygen difference are unchanged with healthy aging.Central Illustration

Concomitant latent pulmonary vascular disease leads to impaired global cardiac performance in HFpEF
ConclusionsLatent PVD is a feature of HFpEF and is associated with impaired RV functional reserve, global diastolic filling and LV-CI. This can be quantified by CMR and used to identify patients likely to benefit from IASD implantation.

Systemic Hypertension in Low Gradient Severe Aortic Stenosis with Preserved Ejection Fraction.
CONCLUSIONS: Systemic hypertension in LG severe AS with preserved EF is associated with elevated LV filling pressures and pulmonary hypertension. Treatment of hypertension with vasodilator therapy results in a lowering of the total LV afterload, with a decrease in LV filling pressures and pulmonary artery pressures. These findings have important implications for the management of patients with LG severe AS with preserved EF and hypertension. PMID: 23956211 [PubMed - as supplied by publisher]
