Combined Use of Radiofrequency-ablation and Balloon-septostomy in the Creation of a Stable Inter-atrial Communication
Though graded balloon-atrial-septostomy (BAS) has been accepted as an effective palliative therapy for severe pulmonary arterial hypertension, spontaneous closure of septostomy is not uncommon. Radiofrequency-catheter-ablation (RFA), which has the potential to cause irreversible damage around the rim of created inter-atrial communication, might contribute to prevent the spontaneous closure. In patients with severe pulmonary arterial hypertension, the combined use of RFA and BAS (CURB) is investigated to create a stable inter-atrial communication.

Comparison of Different Cardiac Output Measurement Methods in Patients Undergoing Right Heart Catheterization
The objective of this observational study is to compare cardiac output evaluation by the Direct Fick method, Indirect Fick method and Thermodiluition in pulmonary hypertension (PH) patients undergoing right heart catheterization (RHC). The main questions it aims to answer are: - Are these methods interchangeable? - Can possible discrepancies influence risk stratification and therapeutic management of PH patients? All consecutive patients aged ≥18 years, referred for RHC for suspected PH, will be included. Exclusion criteria will be contraindications to RHC, cardiac shunts and failure to obtain...

Comparison of Vasodilator Response of Inhaled Epoprostenol and Inhaled Nitric Oxide
The overarching goal of this study is to examine the acute vasoreactive response to both inhaled nitric oxide and inhaled epoprostenol across both traditionally and non-traditionally interrogated phenotypes in PH, and to further characterize the relationship of vasoreactivity to disease severity and PH phenotype.

COMPERA / COMPERA-KIDS
In view of the manifold options for mono- and combination therapy that have now emerged for patients with pulmonary (arterial) hypertension (PH/PAH), controlled clinical trials can only provide part of the information needed for optimal management. In order to gather adequate data on PAH/PH treatment in routine clinical care, the ongoing COMPERA registry prospectively documents consecutive patients with newly initiated treatment of PAH/PAH since May 2007. The internet-based registry fulfills high quality standards through several measures (planned minimum centre contribution of at least 10 patients per year, automated plausibility checks ...

COMPression of Left Main coRonary artEry in patientS With Pulmonary Arterial Hypertension aSymptomatIc fOr aNgina
The prevalence of critical ab extrinsic compression of left main coronary artery (LMCA) is very high in patients with pulmonary arterial hypertension (PAH) symptomatic for angina (up to 40% according to a recent study of 121 patients with PAH). The element that most of all correlates with the degree of coronary stenosis is the diameter of the pulmonary artery (PA). In particular, a diameter ≥ 40 mm has a sensitivity of 83% and a specificity of 70% in patients with angina. Critical stenosis of LMCA is a risk factor for sudden death and in these condition percutaneous coronary angioplasty with stent implantation has proven to be a safe...

Consistency of Electrical Cardiometry and Pulmonary Artery Catheter
Currently, the gold standard method to estimate CO in patients with PAH or RV dysfunction is pulmonary artery catheter (PAC), however, the invasiveness and complexity of PAC has limited its usefulness in many clinical scenarios. By measuring the thoracic electrical bioimpedance, electrical cardiometry (EC) technique has been reported to noninvasively estimate cardiac output (CO) and other parameters related to cardiac contractility and fluid status in various cardiovascular disorders. However, in patients with pulmonary arterial hypertension (PAH) and/or right ventricular (RV) dysfunction, few study has been reported. The aim of this...

Correlation of Right Atrial Strain With Pulmonary Hypertension, Right Ventricular Function And Outcome In Pediatric Patients
This observational study aims to assess correlation of right atrial strain measured by two-dimensional speckle tracking echocardiography with intraoperatively measured pulmonary artery pressures, other indices of right ventricular function and short term postoperative outcome.
