Introduction: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by functional abnormalities of the right ventricular (RV). RV ejection fraction (EF) determined by cardiac magnetic resonance (CMR) imaging is accepted as gold standard measure of RV systolic function.. Hypothesis: RV global longitudinal strain (GLS) by 2-dimensional speckle tracking echocardiography (2DSTE) is correlated with CMR-RVEF, and associated with cardiac events in patients with ARVC.. Methods: We studied 50 patients referred with suspected ARVC. Of them, 19 patients (Group A) were diagnosed as ARVC, while remaining 31 patients (Group B) were not diagnosed due to not meeting criteria. All patients underwent CMR for measurements of RVEF, and echocardiography with conventional assessment including tricuspid annular plane systolic excursion (TAPSE), RV end-diastolic and end-systolic area (RVEDA, RVESA) and RV fractional area change (RVFAC), and with 2DSTE analyses of GLS which was expressed as the ...
Introduction: Right ventricular (RV) hypertrophy followed by RV dysfunction is the main cause of mortality in pulmonary hypertension (PH). The protective role of the inhibition of ABCC4 membrane transporter in pulmonary vascular remodeling has been recently shown. However, our knowledge about the expression of other ABC membrane transporters in the pulmonary vasculature and their role in PH and RV function is limited.. Aim: The current study addresses the role of ABCG2 transporter in the right ventricular function in the well established hypoxia-induced PH murine model.. Methods: Expression studies have been carried out on lung samples obtained from patients with idiopathic pulmonary arterial hypertension and from healthy controls.. Age- and sex-matched WT (n≥9) and ABCG2 knockout (n≥9) male mice were housed in normoxic (21% O2) and hypoxic (10% O2) environment for total of 4 weeks. Hemodynamic parameters such as RV systolic pressure, left ventricular systolic pressure and blood pressure ...
Patent foramen ovale (PFO) is present in approximately 25% of the general population. PFO is characterized by intermittent shunting of blood from the right to the left atrium, especially in the context of increased right-sided filling pressures, with risk of paradoxical embolism. We describe a 69-year-old woman presenting with acute chest pain, severe dyspnoea, and acute inferolateral ST-segment elevation on the electrocardiogram. The patient was diagnosed with myocardial infarction and failure of the right cardiac ventricle, which was considered to be secondary to extensive pulmonary embolism leading to increased filling pressures and paradoxical coronary embolism. The patient underwent emergent percutaneous interventions with coronary thrombus extraction and pulmonary thrombus fragmentation and local thrombolysis. The patient was free of symptoms at follow up 6 months later and echocardiography showed substantially improved right ventricular function. We discuss issues related to the ...

Purpose: To estimate the prevalence of pulmonary artery hypertension (PAH) and right ventricular (RV) dysfunction in COPD patients in the Kirov region of Russia.. Material and methods: 1088 COPD patients (mean age 55±14 years, 97% men and 3% women) were studied. All the patients underwent physical examination, laboratory investigations and transthoracic echocardiography. RV end-diastolic diameter, RV wall thickness and right atrium (RA) area were measured. The systolic pulmonary arterial pressure (PAP) was measured by pulsed Doppler (systolic PAP = tricuspid regurgitation pressure gradient + estimated RA pressure). RA pressure was estimated based on the diameter and respiratory variation of the inferior vena cava. Mean PAP was calculated with formula: mean PAP = 0.61×PA systolic pressure + 2 mm Hg. Global RV systolic function was estimated using RV myocardial performance index and RV fractional area change. RV diastolic function was assessed using transtricuspid E/A ratio and E/E ...
Pulmonary hypertension (PH) is a progressive process that leads to right ventricular (RV) overload, hypertrophy, dilatation and RV failure. In cases with chronic heart failure, this condition is associated with more severe symptoms and worse outcomes.Transthoracic echocardiography can give several parameters which correlate with right heart haemodynamics, and should be performed in a case of suspected PH. Several parameters are important for estimation of the RV function, which can be reason for poor outcome: right atrial and ventricular dimensions and volumes, functional area changes, tricuspid annular plane systolic excursion (TAPSE), myocardial performance index, infe- rior vena cava size and collapsibility, S velocity estimated by Tissue Doppler Imaging, and additional information obtained from the advance echocardiograpic techniques, like strain, strain rate, three-dimensional echocardiography. Estimation of PH based on Doppler echo- cardiography measurements is not suitable for screening of mild,
Most previous studies have used simple measures such as RV fractional area change or tricuspid annular plane excursion to demonstrate the prognostic importance of RV function in patients with heart failure or recent myocardial infarction. As an important advance, Park et al. (1) compare these established measures with newer 2D deformation measures and conclude that RV longitudinal strain provides better predictive accuracy. They used velocity vector imaging, a technique that tracks unique 2D ultrasound patterns within the RV endocardium and measures the distance and direction of their movement between image frames. This is similar, but not identical, to other 2D strain techniques, and the degree to which the results of this study can be generalized remains untested (13). Furthermore, deformation of the interventricular septum is predominantly affected by the LV, and there is contention over whether it should be incorporated in global measures of RV function. The data of Park et al. (1) suggest ...

Caring for the critically ill patient with acute right ventricle (RV) failure is a diagnostic and management challenge. A thorough understanding of normal RV anatomy and physiology is essential to manage RV failure. Despite the fact that the RV is essentially a volume chamber that ejects into a low-pressure system, the left ventricle contributes significantly to RV function through maintenance of the transseptal gradient (TSG). Preserving systemic mean arterial pressure maintains the TSG and RV perfusion. Various pathological states cause acute RV failure by decreasing the TSG and RV perfusion and/or increasing pulmonary vascular resistance ...
Pulmonary embolism (PE) represents a prevalent cause of morbidity and mortality in the United States, with approximately 600 000 cases diagnosed annually. The mortality rate for untreated PE is as high as 30%. Right ventricular (RV) dysfunction is a sign of possible adverse outcomes with right-sided heart failure being the usual cause of death from PE. There is a spectrum of clinical presentations associated with PE diagnoses, from incidental and asymptomatic to rapid hemodynamic collapse. Despite successes in identifying patients with "high-risk" PEs for aggressive thrombolytic interventions and "low-risk" PEs for outpatient anticoagulation, a significant lack of consensus exists regarding intervention modalities for PEs identified as "intermediate risk" or "submassive," defined as normotensive (systolic blood pressure ≥90 mm Hg) with acute RV dysfunction and myocardial injury ...
Description: BNP is a substance secreted from the ventricles or lower chambers of the heart in response to changes in pressure that occur when heart failure develops and worsens. BNP is increased in congestive heart failure, left ventricular hypertrophy, acute myocardial infarction, coronary angioplasty, and hypertension. Elevations are also observed in pulmonary hypertension (indicating right ventricular dysfunction), acute lung injury, hypervolemic states, chronic renal failure and cirrhosis. Decreasing levels indicate therapeutic response to anti-hypertensive therapy ...

The literature on right ventricular systolic dysfunction (RVSD) in peripartum cardiomyopathy (PPCM) patients is scanty, and it appears that RV reverse remodelling in PPCM has not been previously described. This study thus aimed to assess RVSD and remodelling in a cohort of PPCM patients in Kano, Nigeria. A longitudinal study carried out in 3 referral hospitals in Kano, Nigeria. Consecutive PPCM patients who had satisfied the inclusion criteria were recruited and followed up for 12 months. RVSD was defined as the presence of either tricuspid annular plane systolic excursion (TAPSE) |16 mm or peak systolic wave (S) tissue Doppler velocity of RV free wall |10 cm/s. For the purpose of this study, recovery of RV systolic function was defined as an improvement of reduced TAPSE to ≥16 mm or S to ≥10 cm/s, without falling to reduced levels again, during follow-up. A total of 45 patients were recruited over 6 months with a mean age of 26.6 ± 7.0 years. RV systolic function recovery occurred in a total of
Perspective: Systemic right ventricles are at high risk of contractile dysfunction, the cause of which is still unclear. The chronic exposure of the morphological right ventricle to systemic pressure leads to significant hypertrophy. Ischaemia has been postulated to contribute to the right ventricular systolic dysfunction by a number of mechanisms. Supply demand mismatch from an inadequate coronary circulation to support the hypertrophied right ventricle may contribute. In addition, systemic arterial hypoxaemia in the preoperative period and the cardiopulmonary bypass for correction may damage the RV myocardium1, 2, 3. Small numbers of paediatric and adult patients with systemic right ventricles have been studied using myocardial perfusion single photon emission tomography (SPECT) with Sestamibi. A variety of fixed and inducible perfusion defects have been described and believed to be associated with the degree of right ventricular dysfunction and the delay to corrective surgery 2, 3. Myocardial ...
Tricuspid Annular Plane Systolic Excursion [TAPSE] in a patient with severe PAH during a vasodilatory test with epoprostenol: Left panel depicts the localizatio
BACKGROUND: There is no clinical evidence supporting medical treatment for the failing systemic right ventricle in patients with transposition of the great vessels with atrial switch. Cardiac magnetic resonance studies have shown a significant degree of myocardial fibrosis in right ventricles in the systemic position, which predisposes to systolic and diastolic dysfunction. Aldosterone is a widely recognized neurohormonal marker involved in the formation of myocardial fibrosis and the treatment with aldosterone antagonists has shown a decrease in ventricular mass in hypertensive patients, presumably related to reduction of myocardial fibrosis.. HYPOTHESIS: Low dose of eplerenone, a selective mineralocorticoid receptor blocker, in patients with systemic right ventricle can reduce the ventricular mass by means of a reduction in myocardial fibrosis, resulting in improved systolic function.. PATIENTS AND METHODS: Randomized, double blind, parallel clinical trial comparing eplerenone (50mg daily) ...
Aims. The levels of plasma brain natriuretic peptide (BNP) are known to be elevated in patients with primary pulmonary hypertension (PH). We sought to verify the sensitivity and specificity of plasma BNP levels for the diagnosis of PH in HIV infected patients.. Methods and Results. Plasma N-terminal proBNP levels were measured in 16 patients with HIV disease and a confirmed diagnosis of PH and in 77 control HIV patients with no cardiac or pulmonary disease. All patients underwent an echocardiographic and Doppler examination focused on the evaluation of right ventricular (RV) geometry and function. An abnormal value of N-terminal proBNP (,153 pg/ml in males and ,88 pg/ml in females) yielded a 91% specificity and a 81% sensitivity for the diagnosis of PH. Three PH patients with normal N-terminal but similar transtricuspidal and transpulmonary gradients in comparison to those with abnormal N-terminal pro-BNP had normal indices of RV function.. Conclusions. Abnormal plasma N-terminal proBNP levels ...
Life expectancy < 3 months Renal insufficiency Pregnant Unable to follow-up All enrolled patients had a TTE performed by cardiologists looking for signs of RV dysfunction, including TAPSE on A4C. Study outcomes: All-cause mortality at 30 days, secondary outcome was PE-specific mortality Results:. 782 patients were included (66 others were removed due to incomplete TTE documentation, those excluded did not differ in terms of demographics, past history, clinical presentation). All were anticoagulated.. TAPSE range was 0.9-4.0 cm, with a median of 2.0 cm. ROC Curve analysis showed that the best cut-off for PE was 1.6 cm. 146 of the 782 patients had a TAPSE of < 1.6 cm. These patients were older, less likely to be male, had a higher prevalence of chronic heart disease or AFib, and more signs of clinical severity (syncope, tachycardia, low sats, hypotension [Editor note: presumably only brief episodes of hypotension since a normal blood pressure was required for inclusion]). 35 patients died by 30 ...

AbstractRight heart failure (RHF), e.g. due to pulmonary hypertension (PH), is a serious health issue with growing occurrence and high mortality rate. Limited efficacy of medication in advanced stages of the disease constitutes the need for mechanical circulatory support of the right ventricle (RV). An essential contribution to the process of developing right ventricular assist devices (RVADs) is the in vitro test bench, which simulates the hemodynamic behavior of the native circulatory system. To model healthy and diseased arterial-pulmonary hemodynamics in adults (mild and severe PH and RHF), a right heart mock circulation loop (MCL) was developed. Incorporating an anatomically shaped silicone RV and a silicone atrium, it not only enables investigations of hemodynamic values but also suction events or the handling of minimal invasive RVADs in an anatomical test environment. Ventricular pressure-volume loops of all simulated conditions as well as pressure and volume waveforms were recorded and compared

Until recently, patients with advanced heart failure had few options other than cardiac transplantation. With advances in left ventricular assist devices (LVAD), however, these patients now have a viable, long-term alternative with the HeartMate II and Heartware. Unfortunately, right ventricular failure (RVF) is a common complication following implantation of an LVAD and can be associated with increased morbidity and mortality. The incidence of RVF post-implantation has been reported to be between 20%-50%. Risk factors include both patient characteristics and hemodynamic parameters, but definitive risk factors are unknown. Some risk factors may include gender, underlying disease state, increased central venous pressure (CVP), decreased right ventricular (RV) stroke work index, pulmonary hypertension, and signs of end organ damage.
This is a prospective, observational, multicenter study. The primary aim of the study is to assess the accuracy of spiral CT scan to detect right ventricular dysfunction as compared to current gold standardin patients with pulmonary embolism. At the purpose of this study right ventricular dysfunction as assessed by transthoracic echocardiography and serum levels of troponin are considered as gold standard.. The secondary aim of the study is to assess the prognostic value of right ventricular dysfunction as assessed by spiral CT scan. ...
We have shown that late clinical arrhythmia in patients with the Mustard procedure for transposition of great arteries relates to impaired systemic right ventricular function.. Our radionuclide angiographic data reinforce previous studies showing systemic right ventricular dysfunction in patients undergoing the Mustard procedure for transposition of great arteries.4 5 18 Many of our adult patients were asymptomatic at follow up. However, during exercise stress, their cardiac limitations became apparent, as manifested by their decreased maximum workload, diminished anaerobic threshold andV˙o 2max, and lower systemic ventricular ejection fraction.19-21 Maximum oxygen uptake of 17.5 ml/kg/min at a mean of 23.4 years after the Mustard procedure in our adult cohort was significantly lower than the mean of 27 ml/kg/min at 10.3 years after Mustard operation in a report on young adolescents.22 Right ventricular ejection fraction from the present series, both at rest (44.5%) and during exercise (49.3%), ...
Bronchospasm is one of the most feared complications occurring in anesthesia. 7% of all anesthesia-related deaths in France are attributed to bronchospasm [1]. 9% of asthmatic patients will experience intraoperative bronchospasm during general anesthesia. Additionally, adverse respiratory events, including bronchospasm, accounted for 28% of claims regarding anesthesia-related brain damage or death, and resulted in the highest mean cost per closed claim in anesthesia [2]. Bronchospasm is a sudden constriction of bronchial smooth muscle resulting in narrowing of the small airways, which causes increased work of breathing, decreased airflow, air trapping, dynamic hyperinflation, and VQ mismatch. Additionally, it can increase pulmonary vascular resistance resulting in right ventricular overload [3]. Bronchospasm can be separated into two categories based on its precipitating factors: allergic and non-allergic. Allergic bronchospasm is IgE-mediated and typically presents with cutaneous symptoms, ...

Due to her dyspnea in the setting of MCTD, a transthoracic echocardiogram was obtained. It demonstrated severe pulmonary hypertension (PASP 85) with a dilated hypertrophied right ventricle and moderately reduced right ventricular systolic function. Her six-minute walk test (6MWT) demonstrated an ambulation of 1,570 feet on room air with a corresponding modified Borg dyspnea score of 5. A right heart catheterization was obtained and showed a right ventricle systolic pressure of 74 mmHg, a right ventricle diastolic pressure of 10, a pulmonary capillary wedge pressure of 10 and a pulmonary artery mean pressure of 51. A pulmonary angiography was negative for chronic or acute thrombopulmonary embolus. She was classified with PAH class IIIA and eventually started on ambrisentan.. A repeat transthoracic echocardiogram one year later demonstrated an estimated pulmonary arterial systolic pressure of 72 mmHg and moderate to severe reduction in right ventricular systolic function. Her 6MWT and Borg dyspnea ...
A four chamber steady state free precession cine image was acquired followed by a breath hold cine gradient echo-planar tagging sequence in the same plane, using a modification of the technique of Kozerke [1] to mark a line across the basal RV and LV myocardium with a labelling pre-pulse (figure 1). Movements of the labelled myocardium were then tracked automatically by multi-resolution image registration [2] and the end points cubic spline interpolated between time points so that the position of the RV free wall, and its displacement, could be derived at any required time-point in the cardiac cycle. ...
DISCUSSION. In general, patients with biventricular assist devices present lower survival rates in comparison with those with single LVAD (53% vs. 80%). The inferior survival rates of patients with biventricular support can be explained by patient selection and/ or increased incidence of associated comorbidities. However, considering the lack of best practices related to technique, VAD adjustments, anticoagulation, and postoperative management of patients implanted with intracorporeal biventricular support devices, it is possible that many of these complications could be prevented[1,3].. In our service, temporary ventricle support is performed by inserting pulmonary artery cannulation through the right jugular vein using a flexible wire-reinforced single-stage 17 Fr cannula. Venous drainage is performed using a multiple-stage 25 Fr cannula introduced through the right femoral artery into the RA. Flow can reach up to 5 L/min by connecting the cannula to a centrifugal pump (Centrimag or Sorin). A ...
A randomized controlled trial was performed at three centers. The patient population included adults with congenitally corrected as well as surgically palliated transposition of the great arteries (TGA). Patients with New York Heart Association (NYHA) functional class III or IV were excluded. The exercise protocol consisted of 32 minutes of step aerobics interval training three times per week for 10 consecutive weeks. Patients exercised to 90% of maximum heart rate based on prerandomization exercise testing. Perceived health status was measured with the short form-36 (SF-36) instrument, while quality of life was measured with the TAAQOL instrument, which was specifically designed to study quality of life in adults with congenital heart disease. Patients underwent exercise testing, measurement of NT-proBNP, and assessment of quality of life at enrollment and after the study period.. ...

Sixty-five children who underwent biventricular repair were extubated early (immediately after chest closure in the operating room) or were extubated later on intensive care unit (ICU). The results of these two different strategies were compared. Early extubation resulted in better cardiac output, fewer pleural effusion, and shorter stay in the ICU and hospital. The authors concluded that early extubation is safe and feasible and has a beneficial effect on the postoperative course.. ...

Dr. Simons research focus is understanding right ventricular (RV) adaptation and eventual failure in heart failure and pulmonary hypertension (PH) as a translational scientist. Dr. Simons labs focus on 1) advanced analysis of clinical hemodynamics, 2) integration of imaging and hemodynamics to better assess right ventricular function, and 3) early phase clinical trials in pulmonary hypertension and heart failure. His recent projects include a phase II study of inhaled nitrite for pulmonary hypertension (ClinicalTrials.gov NCT01431313), assessment of right ventricular-pulmonary arterial coupling in pulmonary hypertension patients and its relation to outcomes, right ventricular strain analysis by echocardiographic speckle tracking to screen a variety of patients for right ventricular dysfunction, assessment of right ventricular myocardial biaxial biomechanics in a murine model of pressure overload, and phenotyping a nonhuman primate model of HIV-associated pulmonary hypertension. He is involved ...
The right ventricle (RV) has an important contribution to the overall cardiac function; however, data regarding RV function in DM are still rather incomplete. Diabetes mellitus, particularly type 2 DM, affects RV diastolic function in the presence of normal RV systolic function. Myocardial dysfunction in DM is not confined to the LV, but also involves the RV. The impairment of RV function encompasses both systolic and diastolic abnormalities as well [10]. Tissue Doppler imaging is a useful tool to detect early abnormalities of RV diastolic and systolic dysfunction in patients with DM [10-12]. The alterations in myocardial function may be attributed to ventricular interdependence as well as to the uniform effect of diabetes on the cardiac function [10]. Impairment in RV myocardial function is evident mainly by the application of TDI-derived indices, which tend to correlate significantly with the severity and complications of DM. Type 2 DM has been reported to influence the RV function in the ...

Echocardiographic measurements of right atrial (RA) size are associated with worse outcome in PH, however the association between RA function and death in PH has not been well-described. 160 PH patients (World Health Organization groups 1-5) underwent cardiac magnetic resonance imaging (cMRI) and right heart catheterization (RHC) within 6 weeks of each other at a tertiary care academic medical center in the United States. We measured cMRI RA maximum and minimum volumes indexed to body surface area and calculated RA emptying fraction (RAEF). We evaluated the relationship between RAEF and clinical ...
This study demonstrated that the combination of markers of RVD (by echocardiography) or myocardial injury (using cardiac troponin I testing) and assessment of thrombotic burden (using CCUS) improved the identification normotensive patients with acute symptomatic PE at high risk of 30-day death from PE. In particular, for the identification of high-risk normotensive patients with acute PE, (1) single prognostic tests (ie, troponin, CCUS, or echocardiography) had limited usefulness; (2) the positive likelihood ratio of PE-related mortality doubled with the addition of a second test; (3) a three-test strategy did not have test characteristics much better than the two-test strategy; and (4) the two-test strategies had higher positive predictive values in PESI high-risk patients.. The recent guidelines by the European Society of Cardiology22 proposed to distinguish between high-risk patients with acute PE (ie, clinically evident right ventricular failure with refractory arterial hypotension and ...
The morning before I had my baby girl I had perfect blood pressure level and no protien in my urine. The next morning when I went in with contractions I had copius amounts of protien in my urnie, partial kidney failure, a blood pressure of 210/120, and placental abruption. This all happened within 24 hours of being perfectly fine. I dont have a history of high blood pressure for me or in my family. And I was at an average size when I got pregnant. Even before that at 5 months I went to the emergency room with severe right side pains the first urine test they took came back with protien and I was told I may have preeclampsia. They took another one and loe and behold there was no protein. A change can happen within a drop of a dime... As I learned. So is it possible to develop pe without underlying symptoms... yes! And it is even more possible to develop pe in a VERY SHORT period of time ...

The pulmonary arterial hypertension (PAH) patients have high rate of mortality due to right ventricle (or ventricular) (RV) failures. A lot of research work is being carried out in the area, however no treatment is available that could contrast the rise in mortality rates in PAH patients. β1-adrenoceptor blockers (β-blockers, BB) reduced mortality in left heart failure, but they do not explored much at clinical level. Recent studies suggest β-blockers might be beneficial in PAH; however the mechanisms remain unknown. The present review article would put light on all these aspects of PAH along with latest ways for the management of PAH.. ...

Background Right ventricular ejection fraction (RVEF) is an emerging prognostic predictor of patients with pulmonary hypertension (PH).. Aim We sought to evaluate the accuracy and suitability of two echocardiographic parameters of right ventricular systolic function: tricuspid annular plane systolic excursion (TAPSE) and systolic lateral tricuspid annular motion velocity (TVlat) in the monitoring of RVEF of PH patients.. Methods Consecutive 37 patients with PH (median pulmonary arterial pressure 36 (28 -43) mmHg) were studied. We measured TAPSE and TVlat as echocardiographic indices of RVEF. TAPSE and TVlat measured at baseline and at follow-up, and the changes during follow-up were compared with those of magnetic resonance imaging (MRI)-derived RVEF. Receiver operating characteristic (ROC) analysis was conducted to calculate the cut-off levels of TAPSE and TVlat for the identification of patients with improved RVEF.. Results TAPSE and TVlat were significantly correlated with MRI-derived RVEF at ...
