BACKGROUND: Single measurements of left ventricular filling pressure at rest lack sensitivity for identifying heart failure with preserved ejection fraction (HFpEF) in patients with dyspnea on exertion. We hypothesized that exercise hemodynamic measurements (ie, changes in pulmonary capillary wedge pressure [PCWP] indexed to cardiac output [CO]) may more sensitively differentiate HFpEF and non-HFpEF disease states, reflect aerobic capacity, and forecast heart failure outcomes in individuals with normal PCWP at rest...

Introduction: High pulmonary vascular resistance (PVR) in orthotopic heart transplantation (OHT) candidates is a risk factor of right ventricle failure after the procedure. However, the increase of PVR may be a consequence of the life-threatening deterioration of the left ventricle function. The use of mechanical circulatory support (MCS) seems to be the best solution, but it is reimbursed only in active OHT candidates. Aim: We performed a retrospective analysis of MCS effectiveness in maintaining PVR at values accepted for OHT...

BACKGROUND: The pulmonary artery pulsatility index (PAPi) - defined as the ratio of pulmonary artery pulse pressure to right atrial pressure -emerged as a powerful predictor of right ventricular (RV) failure in patients with acute inferior myocardial infarction and those undergoing left ventricular assist device placement, however, its prognostic utility in the advanced heart failure population remains largely unknown. METHODS AND RESULTS: We comparatively analyzed PAPi with traditional indices of RV function including RV stroke work index (RVSWI) and right atrial /pulmonary capillary wedge pressure ratio (RAP/PCWP) in the ESCAPE trial...

BACKGROUND: There is a paucity of data on the utility of right atrial pressure (RAP) for estimating pulmonary capillary wedge pressure (PCWP) in patients with normal ejection fraction (EF), including patients with heart failure with preserved EF. METHODS: Mean RAP was compared with PCWP in 129 patients (mean age, 61 ± 11 years; 45% men) with exertional dyspnea enrolled in a multicenter study. Measurements included left ventricular volumes, EF, and mitral inflow velocities...

Objective: To compare the acute hemodynamic effects of intravenous fasudil with different dosage on patients with congenital heart defects (CHD) and severe pulmonary arterial hypertension (PAH). Methods: Sixty patients (37±17 years old) with CHD and PAH were consecutively enrolled. All patients underwent heart catheterization. The patients were randomly divided into two groups: the regular dosage group and the large dosage group. At initiation and 30 min after intravenous fasudil(30 mg and 60 mg respectively), the following hemodynamic parameters were measured and calculated: right atrial pressure(RAP), pulmonary arterypressure(PAP) , systemic artery pressure (SAP), pulmonary capillary wedge pressure(PCWP) , pulmonary vascular resistance(PVR) and systemic vascular resistance( SVR), cardiac index (CI) and artery oxygen saturation (SaO(2))...

Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is widely used in cardiogenic shock. It provides systemic perfusion, but left ventricular (LV) unloading is suboptimal. Using a closed-loop, real-time computer model of the human cardiovascular system, cardiogenic shock supported by peripheral VA ECMO was simulated, and effects of various adjunct LV unloading interventions were quantified. After VA ECMO initiation (4 L/min) in cardiogenic shock (baseline), hemodynamics improved (increased to 85 mm Hg), while LV overload occurred (10% increase in end-diastolic volume [EDV], and 5 mm Hg increase in pulmonary capillary wedge pressure [PCWP])...

BACKGROUND: Mismatch between right- and left-sided filling pressures is poorly understood in heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: We retrospectively analyzed 170 patients with HFpEF (EF≥40%) who underwent right heart catheterization. Low match (right atrial pressure [RAP]<10mmHg and pulmonary capillary wedge pressure [PCWP]<10mmHg) was 76%, high match (RAP≥10mmHg and PCWP≥22mmHg) was 6.5%, high-R mismatch (RAP≥10mmHg and PCWP<22mmHg) was 12%, and high-L mismatch (RAP<10mmHg and PCWP≥22mmHg) was 5...

The full potential of mechanical circulatory systems in the treatment of cardiogenic shock is impeded by the lack of accurate measures of cardiac function to guide clinicians in determining when to initiate and how to optimally titrate support. The left ventricular end diastolic pressure (LVEDP) is an established metric of cardiac function that refers to the pressure in the left ventricle at the end of ventricular filling and immediately before ventricular contraction. In clinical practice, LVEDP is typically only inferred from, and poorly correlates with, the pulmonary capillary wedge pressure (PCWP)...

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides mechanical circulatory support for patients with advanced cardiogenic shock, facilitating myocardial recovery and limiting multi-organ failure. In patients with severely limited left ventricular ejection, peripheral VA-ECMO can further increase left ventricular and left atrial pressures (LAP). Failure to decompress the left heart under these circumstances can result in pulmonary edema and upper body hypoxemia, that is, myocardial and cerebral ischemia...

Elevated left ventricular (LV) filling pressures are commonly reported in patients with heart failure with preserved ejection fraction (HFpEF) and are associated with impaired relaxation in diastole. Relaxation has been assessed by Doppler, but the methods for doing so are indirect and heavily influenced by loading conditions. The aim of this study is to assess LV volume-time relation in patients with HFpEF, when correcting for left atrial driving pressure and chamber size, using cardiac magnetic resonance imaging (cMRI)...

BACKGROUND: Lower serum chloride (Cl) is associated with mortality in heart failure patients and may be more prognostically relevant than sodium. However, the association of hemodynamics and Cl levels is unknown. METHODS: 438 sequential patients with advanced chronic heart failure (ACHF) underwent invasive hemodynamic assessment with measured serum Cl levels during an evaluation for ACHF. Patients were followed for death, heart transplant (HT), or ventricular assist device placement (VAD)...

OBJECTIVES: This study investigated to define graft dysfunction and to determine its incremental association with long-term outcome after heart transplantation (HT). BACKGROUND: Although graft failure is an established cause of late mortality after HT, few studies have analyzed the prognostic value of graft dysfunction at 1- and 5-year follow-up of HT. METHODS: Patients who underwent HT and completed their first annual evaluation with right heart catheterization and echocardiography at Stanford University between January 1999 and December 2011 were included in the study...

BACKGROUND: In nonrandomized, open-label studies, a transcatheter interatrial shunt device (IASD, Corvia Medical) was associated with lower pulmonary capillary wedge pressure (PCWP), fewer symptoms, and greater quality of life and exercise capacity in patients with heart failure (HF) and midrange or preserved ejection fraction (EF ≥40%). We conducted the first randomized sham-controlled trial to evaluate the IASD in HF with EF ≥40%. METHODS: REDUCE LAP-HF I (Reduce Elevated Left Atrial Pressure in Patients With Heart Failure) was a phase 2, randomized, parallel-group, blinded multicenter trial in patients with New York Heart Association class III or ambulatory class IV HF, EF ≥40%, exercise PCWP ≥25 mm Hg, and PCWP-right atrial pressure gradient ≥5 mm Hg...

BACKGROUND: Several echocardiographic parameters are currently used to evaluate left ventricular (LV) filling pressure. However, these parameters are not always consistent in the clinical setting. We aimed to determine a novel parameter by multiplying log B-type natriuretic peptide (lnBNP) and the ratio of mitral inflow early and late diastolic filling velocities (E/A) for the prediction of pulmonary capillary wedge pressure (PCWP). METHODS AND RESULTS: One hundred ninety-eight patients suspected of chronic heart failure were analyzed...

Aims: Evidence on the impact on clinical outcome of active mechanical circulatory support (MCS) devices in cardiogenic shock (CS) is scarce. This collaborative meta-analysis of randomized trials thus aims to investigate the efficacy and safety of percutanzeous active MCS vs. control in CS. Methods and results: Randomized trials comparing percutaneous active MCS to control in patients with CS were identified through searches of medical literature databases. Risk ratios (RR) and 95% confidence intervals (95% CI) were calculated to analyse the primary endpoint of 30-day mortality and device-related complications including bleeding and leg ischaemia...
