BACKGROUND: Pulmonary hypertension (PH) is a common and morbid complication of left heart disease with 2 subtypes: isolated post-capillary pulmonary hypertension (Ipc-PH) and combined post-capillary and pre-capillary pulmonary hypertension (Cpc-PH). Little is known about the clinical or physiological characteristics that distinguish these 2 subphenotypes or if Cpc-PH shares molecular similarities to pulmonary arterial hypertension (PAH). OBJECTIVES: The goal of this study was to test the hypothesis that the hemodynamic and genetic profile of Cpc-PH would more closely resemble PAH than Ipc-PH...

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation)...

BACKGROUND: Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH). We evaluated the characteristics of cardiac dysfunction in patients with PAH complicated by PAA. METHODS: Echocardiography and right-heart catheterization were performed in 130 PAH patients to measure the maximum dimensions of the main pulmonary artery (MPA) trunk and evaluate right ventricular (RV) and left ventricular (LV) function. RESULTS: A diameter of >40mm was defined as PAA in the MPA trunk...

BACKGROUND: In patients with mitral stenosis (MS), pulmonary hypertension (PH) is a significant contributor to the associated morbidity. We aimed to study factors associated with the presence of significant PH (sPH) and whether incorporating body surface area (BSA) in the mitral valve area (MVA) would improve the predictive value of the latter. METHODS: The medical records of 558 patients with severe MS undergoing percutaneous balloon mitral commissurotomy were evaluated over a period of 8 years...

BACKGROUND: Constrictive pericarditis (CP) is characterized by impaired diastolic cardiac function leading to heart failure. Pericardiectomy is considered effective treatment for CP, but data on long-term clinical outcomes after pericardiectomy are limited.Methods and Results:We retrospectively investigated 45 consecutive patients (mean age, 59±14 years) who underwent pericardiectomy for CP. Preoperative clinical factors, parameters of cardiac catheterization, and cardiac events were examined...

AIMS: Pulmonary hypertension (PH) patients have high mortality due to right ventricular failure. Predictors of poor prognostic outcome are increased right atrial volume (RAV) and elevated mean right atrial pressure (mRAP). Our aim was to determine whether RAV measured with 2D echocardiography (2DE) and 3D echocardiography (3DE) can detect elevated mRAP in patients evaluated for PH. METHODS: Of 85 patients prospectively evaluated for PH, 44 patients (63 ± 15 years, 57% female) had 2DE, 3DE and right heart catheterization within 48 h and were in sinus rhythm...

BACKGROUND: Cardiac magnetic resonance (CMR) has promise of being able to provide frequent cardiac morphology and function evaluations noninvasively for repeated follow-ups of pulmonary arterial hypertension (PAH) patients after the initial right heart catheterization (RHC) diagnosis. By using the noninvasive CMR indices, the present study aimed to formulate and validate a prediction model of mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR). METHODS: Both Derivation Cohort (N=25) and Validation Cohort (N=25) of PAH patients underwent CMR and RHC within one week...

BACKGROUND: RV dyssynchrony has been described in patients with pulmonary hypertension (PH) and is an independent predictor of clinical worsening; however, the optimal method for measuring RV dyssynchrony has not been fully established. This study aimed to investigate whether RV dyssynchrony is correlated with hemodynamics and prognosis in PH patients and to identify the best parameter for evaluating RV dyssynchrony. METHODS: This study assessed 100 PH patients, measuring mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), and cardiac index (CI) by right heart catheterization (RHC)...

BACKGROUND: Accurate assessment of cardiac output (CO) is essential for the hemodynamic assessment of aortic valve area (AVA). Estimation of oxygen consumption (VO2) and Thermodilution (TD) is employed in many cardiac catheterization laboratories (CCL) given the historically cumbersome nature of direct continuous VO2 measurement, the "gold standard" for this technique. A portable facemask device simplifies the direct continuous measurement of VO2, allowing for relatively rapid and continuous assessment of CO and AVA...

BACKGROUND: Accurate assessment of Cardiac Output (CO) is a critical measurement in the calculation of aortic valve area (AVA). Due to the known inaccuracy of estimated Fick calculations, many measure thermodilution (TD) CO as well due to previous studies showing better correlation with the gold standard direct CO. Previous studies showed suboptimal correlation between both methods. Most physicians assume that the TD CO is chosen by catheterization laboratory software for AVA evaluation...

BACKGROUND: Right ventricular (RV) function is an independent predictor of clinical outcomes in patients with pulmonary arterial hypertension (PAH). However, it remains controversial which RV parameter should be measured as an appropriate index for the treatment of PAH. The aim of this study was to identify the most useful parameter that correlates with hemodynamics and predicts clinical outcomes in PAH. RESULTS: Most of the clinical and echocardiographic RV parameters were significantly correlated with pulmonary vascular resistance (PVR) as well as mean pulmonary arterial pressure (mPAP)...

In patients with systemic sclerosis, a ratio between forced vital capacity (FVC) and diffusing capacity of carbon monoxide (DLCO, FCV%/DLCO%) >1.5 might be a predictor of pulmonary hypertension (PH). The aim of this study is, therefore, to evaluate whether this index can be used in patients with PH, regardless of etiology. 83 consecutive outpatients with suspected PH at non-invasive work-up underwent spirometry and DLCO test before right heart catheterization (RHC); FVC%/DLCO% ratio was then calculated and compared with mean pulmonary-artery-pressure (mPAP) and mortality at 5-year follow-up...

Patients with pulmonary arterial hypertension (PAH) who do not have an adequate response to therapy with phosphodiesterase-5 inhibitors (PDE-5i) may have insufficient synthesis of cyclic guanosine monophosphate (cGMP). These patients may respond to a direct soluble guanylate cyclase (sGC) stimulator such as riociguat. RESPITE (NCT02007629) was an open-label, multicenter, uncontrolled, single-arm phase 3b study of riociguat in patients with PAH who demonstrated an insufficient response to treatment with PDE-5i...

AIMS: Impaired left ventricular (LV) deformation despite preserved LV ejection fraction (LVEF) is common and predicts outcomes in heart failure with preserved LVEF. We hypothesized that impaired LV deformation at rest is a marker of impaired cardiac systolic and diastolic reserve, and aimed to determine whether resting longitudinal (LS) and circumferential strain (CS) are associated with invasively measured haemodynamic response to exercise in patients with dyspnoea and a normal LVEF...

BACKGROUND: Although pulmonary hypertension due to left heart disease (LHD-PH) accounts for the largest proportion of pulmonary hypertension, few reports on the epidemiological analysis of LHD-PH exist. Recently, pulmonary arterial capacitance (PAC) has attracted attention as a possible factor of right ventricular afterload along with pulmonary vascular resistance. We therefore investigated the clinical significance of PAC in LHD-PH. METHODS: The subject consisted of 252 LHD-PH patients (145 men, mean age 63...

The new percutaneous Impella CP (Cardiac Power; Abiomed, Inc., Danvers, MA) was designed to provide a higher level of support than Impella 2.5 (Abiomed, Inc.). We present the first documented case of a patient that was transitioned from the Impella 2.5 to Impella CP. A 48-year-old male patient with no medical history was transferred to our institution with a one day history of worsening shortness of breath. The patient was unstable and found to have monomorphic ventricular tachycardia at 220 beats/min that was cardioverted to normal sinus rhythm...

Inadvertent complications of jugular vein catheterization are not uncommon, however, a persistent symptomatic carotid-jugular fistula has been rarely reported. A 72-year-old male with infected surgical wound after coxofemoral disarticulation for sarcoma presented with symptoms of acute right heart failure. A fistula between the right common carotid artery (CCA) and the internal jugular vein was demonstrated on Doppler ultrasound and confirmed on computed tomography angiogram. Catheterization of the right CCA seemed not possible using a conventional femoral approach due to the tortuosity and elongation of the brachiocephalic artery...
