Practical Demonstration

Pulmonary hypertension is a hemodynamic disorder defined by abnormally high pulmonary artery pressure that affects the arteries in your lungs and the right side of your heart. In this study, hepatic venous duplex will be done to diagnose and quantify the PH. So that Patients can avoid unnecessary invasive right heart catheterization. This practical demonstration is the key to enrich our experience and knowledge in the field of PH. Objectives of this study was to assess PH status by Hepatic venous Duplex (HVD) as well by right heart catheterization and to compare them. This study was conducted in the Department of Cardiology, BSMMU, Shahbagh, Dhaka extending from July 2018 to December 2019. Total 100 (One hundred) subjects were enrolled in this study. It was an Observational study and includes the subjects between 18 years to 45 years of age. Results of this study shows very close proximity to that of Right heart catheterization. Hemodynamic changes in Hepatic venous duplex study could be used as an alternative diagnostic tool for evaluating moderate to severe pulmonary hypertension. This method could counteract the weakness of the currently used diagnostic methods and improve the accuracy of assessing pulmonary hypertension when combined with other methods.

Heart Lesions

The diagnosis of pulmonary hypertension (PH) requires a right heart catheterization (RHC) that reveals a mean pulmonary artery pressure ≥ 25 mmHg. The pulmonary artery catheter traverse the right atrium and ventricle on its way to the pulmonary artery. The presence of abnormal right heart structures, i.e. thrombus, vegetation, benign or malignant cardiac lesions, can lead to complications during this procedure. On the other hand, avoidance of RHC delays the diagnosis and treatment of PH, an approach that might be associated with worse outcomes. This paper discusses the impact of right heart lesions on the diagnosis of PH and suggests an approach on how to manage this association.

Systemic sclerosis is the most common autoimmune disease associated with pulmonary hypertension. Pulmonary hypertension is a potential predictor of early death, and therefore, recently, interest in a comprehensive study of the diagnosis of pulmonary hypertension associated with systemic sclerosis has been increasing among researchers. Aim. Consideration of current diagnostic issues, as well as the principles of using diagnostic algorithms to verify pulmonary hypertension associated with systemic sclerosis, applied in daily clinical practice. Material and methods. In order to study the literature data, a search was carried out for information on this problem up to 10 years in depth in the Web of Science, PubMed/MEDLINE. During the search, the following terms were used individually and in combination: "systemic sclerosis", "pulmonary hypertension", "DETECT algorithm", "catheterization of the right heart chambers". The main search criteria were studies based on the study of patients with pulmonary hypertension associated with systemic sclerosis: meta-analyzes, original studies, retrospective and cohort studies. Results and discussion. The clinical symptoms of pulmonary hypertension can be nonspecific, which greatly complicates the diagnosis of the disease in the early stages. The absence of a specific clinical picture before the development of an advanced stage of pulmonary hypertension leads to late verification of the diagnosis. Key algorithms used in the daily practice of a doctor make it possible to minimize the number of undiagnosed cases of pulmonary hypertension. Conclusions. Diagnosis of PH associated with systemic sclerosis is often challenging for clinicians to practice. Early diagnosis and therefore treatment of PH are of paramount importance as they improve survival rates in patients with systemic sclerosis. Keywords: systemic sclerosis, pulmonary hypertension, screening, DETECT algorithm, right heart catheterization.

Rv Function

Right ventricular (RV) function strongly associates with mortality in patients with pulmonary arterial hypertension (PAH). Current methods to determine RV function require temporal measurements of pressure and volume. The aim of the study was to investigate the feasibility of using right heart catheterization (RHC) measurements to estimate systolic and diastolic RV function. RV pressure and volume points were fit to P = α(eβV-1) to assess diastolic stiffness coefficient (β) and end-diastolic elastance (Eed). Single-beat methods were used to assess RV contractility (Ees). The effects of a non-zero unstressed RV volume (V0), RHC-derived stroke volume (SVRHC), and normalization of the end-diastolic volume (EDV) on estimates of β, Eed, and Ees were tested using Bland–Altman analysis in an incident PAH cohort (n = 32) that had both a RHC and cardiac magnetic resonance (CMR) test. RHC-derived measures of RV function were used to detect the effect of prostacyclin therapy in an incident PAH cohort and the severity of PAH in prevalent PAH (n = 21). A non-zero V0 had a minimal effect on β with a small bias and limits of agreement (LOA). Stroke volume (SV) significantly influenced estimates of β and Ees with a large LOA. Normalization of EDV had minimal effect on both β and Eed. RHC-derived β and Eed increased due to the severity of PAH and decreased due to three months of prostacyclin therapy. It is feasible to detect therapeutic changes in specific stiffness and elastic properties of the RV from signal-beat pressure-volume loops by using RHC-derived SV and normalizing RV EDV.

Cardiac Shunt

A 52 year old female presented for two weeks of acute onset dyspnea on exertion. She was found to be hypoxic with a room air saturation of 88%. Baseline echocardiogram was normal with the exception of aortic root dilation. Right and left heart catheterizations were performed. The coronary arteries were normal in original and without disease. The right heart catheterization demonstrated normal pulmonary pressures and “no evidence of intra-cardiac shunt”. Repeat echocardiogram was performed with agitated saline contrast and revealed a small amount of right to left shunting across the intra-atrial septum with cough while supine and significant right to left shunting while upright; these findings were consistent with the presence of a patent foramen ovale (PFO) and platypnea-orthodeoxia syndrome. The patient underwent percutaneous closure of her PFO with an Amplatzer device, and exhibited rapid resolution of her symptoms and hypoxia. She is off oxygen and has returned to work as a nurse practitioner. The case highlights the importance of clinical vigilance and consideration of this syndrome in the differential diagnosis of unexplained hypoxia. Our patient had a dramatic and positive outcome: complete alleviation of dyspnea and oxygen dependence after PFO closure.

The present study employed a new right-heart catheterization technique to measure pulmonary arterial pressure, pulmonary arterial wedge pressure, and pulmonary vascular resistance in anesthetized intact-chest, spontaneously breathing mice. Under fluoroscopic guidance, a specially designed catheter was inserted via the right jugular vein and advanced to the main pulmonary artery. Cardiac output was determined by the thermodilution technique, and measured parameters were stable for periods of ≤3 h. Pressure-flow curves in vivo were curvilinear, with mean pulmonary arterial pressure increasing more rapidly at low pulmonary blood flows of 5–10 ml/min and less rapidly at higher blood flow rates. The pressure-flow relationship was shifted to the left by the nitric oxide synthase inhibitor nitro-l-arginine methyl ester (l-NAME) at higher blood flow levels, whereas the cyclooxygenase inhibitor sodium meclofenamate was without effect. The increase in pulmonary arterial pressure in response to acute hypoxia (fractional inspired O2 10%) was augmented byl-NAME but unaltered by sodium meclofenamate. The present results demonstrate that the right-heart catheterization technique can be used to measure pulmonary vascular pressures and responses in the mouse. This is, to our knowledge, the first report of a right-heart catheterization technique to measure pulmonary vascular pressures and responses in the intact-chest, spontaneously breathing mouse and should prove useful for the investigation of pulmonary vascular responses in transgenic mice.
