Right heart catheterisation

Ewa Konik, Jeffrey Geske, William Edwards, Bernard Gersh
A 70-year-old man presented with recent onset, predominantly right-sided heart failure. Echocardiogram demonstrated features of hypertensive heart disease and was suggestive of, but non-diagnostic for, constrictive pericarditis (CP). CT demonstrated mild pericardial thickening. Right heart catheterisation showed elevation and equalisation of diastolic pressures in all cardiac chambers with early rapid filling, minimal ventricular interdependence, and no dissociation of intrathoracic and intracardiac pressures...

BACKGROUND: Mutations in the eukaryotic translation initiation factor 2α kinase 4 (EIF2AK4) gene have recently been identified in recessively inherited veno-occlusive disease. In this study we assessed if EIF2AK4 mutations occur also in a family with autosomal dominantly inherited pulmonary arterial hypertension (HPAH) and incomplete penetrance of bone morphogenic protein receptor 2 (BMPR2) mutations. METHODS: Clinical examinations in a family with 10 members included physical examination, electrocardiogram, (stress)-echocardiography and lung function...

BACKGROUND: Pulmonary arterial hypertension (PAH) is the leading cause of mortality in patients with systemic sclerosis (SSc). We sought to determine the incidence, prevalence and risk factors for PAH development in a large Australian SSc cohort. METHODS: PAH was diagnosed on right heart catheterisation (mPAP >25 and PAWP <15 mmHg at rest). Patients with PH secondary to interstitial lung disease (ILD; defined as abnormal HRCT scan and FVC < 60 %) were excluded...

We present a rare late complication after inferior vena cava filter (IVC) placement. A 52-year-old woman with an IVC presented with sudden onset of chest pain. Cardiac catheterisation and echocardiography revealed an embolised IVC filter strut penetrating the right ventricle. Endovascular retrieval was considered but deemed unsafe due to proximity to the right coronary artery and concern for migration to pulmonary circulation. Urgent removal of the strut was performed via sternotomy. The postoperative course was uneventful...

A 2-year-old girl with a functionally univentricular heart associated with a pulmonary sequestration underwent right lower lobectomy after which increased lung volume with low mean pulmonary artery pressure and pulmonary vascular resistance was documented. A cardiac catheterisation performed after a subsequent total cavopulmonary connection demonstrated favourable Fontan haemodynamics. Lobectomy may have induced compensatory lung growth, contributing to the maintenance of haemodynamics favourable for the long-term success of the Fontan procedure...

OBJECTIVE: Inadequate right ventricular (RV) and pulmonary arterial (PA) functional responses to exercise are important yet poorly understood features of pulmonary arterial hypertension (PAH). This study combined invasive catheterisation with echocardiography to assess RV afterload, RV function and ventricular-vascular coupling in subjects with PAH. METHODS: Twenty-six subjects with PAH were prospectively recruited to undergo right heart catheterisation and Doppler echocardiography at rest and during incremental exercise, and cardiac MRI at rest...

OBJECTIVE: Patients infected with HIV have a direly increased risk of developing pulmonary hypertension (PH), and of dying from the condition. While Africa carries the greatest burden of HIV infection worldwide, there is unclear data summarising the epidemiology of PH among HIV-infected people in this region. Our objective was to determine the prevalence and incidence of PH among HIV-infected people living across Africa. DESIGN: A systematic review and meta-analysis...

BACKGROUND: Pulmonary hypertension (PH) is a serious complication to interstitial lung disease (ILD) and has a poor prognosis. PH is often diagnosed by screening with echocardiography followed by right heart catheterisation. A previous study has shown that a value of NT-pro-brain natriuretic peptide (NT-proBNP) <95 ng/l could be used to rule out PH in patients with ILD. AIM: To evaluate this rule-out test for PH in a new cohort of incident patients with ILD. METHODS: An established database with data from 148 consecutive patients referred from January 2012 to October 2014 was used to identify patients and obtain data from echocardiography, NT-proBNP, diagnosis and lung function...

RATIONALE: Severe pulmonary hypertension (PH) is very uncommon in COPD, and a distinct phenotype has been hypothesised. We aimed to evaluate whether CT can help to recognise this condition non-invasively by measuring small pulmonary vessels. MATERIAL AND METHODS: Patients with COPD who underwent pulmonary function tests, unenhanced CT of the chest and right heart catheterisation (RHC) during a period of stability were included in the study. From 105 included patients, 20 patients with COPD with severe PH (mean pulmonary arterial pressure, mPAP>35 mm Hg) were compared with 20 FEV1-matched and age-matched patients with COPD with mild or without PH (mPAP<35 mm Hg)...

Right heart catheterisation (RHC) may be performed through a mechanical valve prosthesis in the tricuspid position using a partially inflated pulmonary artery flotation catheter. Preprocedural preparation should include an ex vivo trial with an identical valve prosthesis and the type of catheter to be used for the procedure. The operator should expect immediate unloading of the right ventricle due to catheter-associated tricuspid regurgitation, but it is possible to estimate pulmonary vascular resistance using the Fick principle...

BACKGROUND: Right heart catheterisation is the gold-standard for differentiating pre-capillary pulmonary hypertension (high mean pulmonary artery pressure, normal pulmonary wedge pressure) from post-capillary physiology (elevated pulmonary wedge pressure). The new non-invasive parameter, ePLAR (echocardiographic Pulmonary to Left Atrial Ratio) is calculated from the maximum tricuspid regurgitation continuous wave Doppler velocity (m/s) divided by the transmitral E-wave:septal mitral annular Doppler Tissue Imaging e'-wave ratio (TRVmax/E:e')...

CLINICAL INTRODUCTION: A 57-year-old woman with known moderate-to-severe mitral stenosis and atrial fibrillation (AF) presented to the emergency department with acute onset right loin pain after having a coronary angiogram and left and right heart catheterisation through the right femoral route about 28 h ago. The cardiac catheterisation was done after she presented with one episode of troponin-negative chest pain and progressive shortness of breath. She had anterior wall myocardial infarction (MI) 25 years ago, which was thought to be due to coronary artery embolism...

Persistent pulmonary hypertension of the newborn (PPHN) is the most common neonatal form and mostly reversible after a few days with improvement of the underlying pulmonary condition. When pulmonary hypertension (PH) persists despite adequate treatment, the severity of parenchymal lung disease should be assessed by chest CT. Pulmonary vein stenosis may need to be ruled out by cardiac catheterisation and lung biopsy, and genetic workup is necessary when alveolar capillary dysplasia is suspected. In PPHN, optimisation of the cardiopulmonary situation including surfactant therapy should aim for preductal SpO2between 91% and 95% and severe cases without post-tricuspid-unrestrictive shunt may receive prostaglandin E1 to maintain ductal patency in right heart failure...

Invasive assessment of haemodynamics (ventricular, pulmonary) and testing of acute vasoreactivity in the catheterisation laboratory remain the gold standard for the diagnosis of pulmonary hypertension (PH) and pulmonary hypertensive vascular disease. However, these measurements and the interpretation thereof are challenging due to the heterogeneous aetiology of PH in childhood and potentially confounding factors in the catheterisation laboratory. Patients with pulmonary arterial hypertension (PAH) associated with congenital heart disease who have a cardiovascular shunt need to undergo a completely different catheterisation approach than those with idiopathic PAH lacking an anatomical cardiovascular defect...

BACKGROUND: Chronic thromboembolic pulmonary hypertension results from incomplete resolution of pulmonary emboli. Pulmonary endarterectomy (PEA) is potentially curative, but residual pulmonary hypertension following surgery is common and its impact on long-term outcome is poorly understood. We wanted to identify factors correlated with poor long-term outcome after surgery and specifically define clinically relevant residual pulmonary hypertension post-PEA. METHODS AND RESULTS: Eight hundred eighty consecutive patients (mean age, 57 years) underwent PEA for chronic thromboembolic pulmonary hypertension...

INTRODUCTION: Coronary venous catheterisation has been used for performing various cardiologic interventions. The procedure might become complicated due to obstruction offered by the valve of coronary sinus (Thebesian valve) the acute bend of the Great Cardiac Vein (GCV). The present study sought to expound the anatomical considerations of coronary venous catheterization and to elucidate the potential causes of obstruction and the complications of this procedure. MATERIALS AND METHODS: In this cross-sectional observational study, coronary sinus and GCV were dissected in 40, formalin fixed, adult cadaveric human hearts...
