Modeling Right Ventricle Failure After Continuous Flow Left Ventricular Assist Device: A Biventricular Finite-Element and Lumped-Parameter Analysis
AbstractThe risk of right ventricle (RV) failure remains a major contraindication for continuous-flow left ventricular assist device (CF-LVAD) implantation in patients with heart failure. It is therefore critical to identify the patients who will benefit from early intervention to avoid adverse outcomes. We sought to advance the computational modeling description of the mechanisms underlying RV failure in LVAD-supported patients. RV failure was studied by computational modeling of hemodynamic and cardiac mechanics using lumped-parameter and biventricular finite element (FE) analysis. Findings were validated by comparison o...

Abstract 205: Stroke Risk and Symptom Recognition Post Cardiac Catheterization Session Title: Poster Session PM
Over 1.4 million cardiac catheterization procedures (CCPs) take place yearly. CPP related stroke incidence in 1973 was reported as 0.23%. CCPs are invasive in nature with complications occurring due to unintentional trauma to preexisting atherosclerotic aortic plaques or thrombus formation at catheter/guidewire tips. Less common causes of ischemic stroke are air, left ventricular clot, hypotension, arterial dissection, fractured guidewire. Transient neurological deficits have been reported following high-osmolar contrast injection into carotid/vertebral arteries. With improved practice, current stroke incidence is 0.06%. P...

Clinical Use of the Amplatzer Device in the Management of Intracardiac Defects: A Single-Center Experience
Int J Angiol DOI: 10.1055/s-0038-1626718Device therapy is a viable alternative to open heart surgery in the management of intracardiac defects. The Amplatzer septal occluder (ASO) is one such device that has been adapted to close a wide variety of cardiac defects with few complications and a high success rate. This is a retrospective review of all the patients who received the ASO between 2012 and 2016 at the University of Kentucky. In total, 169 patients underwent percutaneous closure of a septal defect with Amplatzer during the timeframe studied, and of those, 91% received the device for an atrial septal defect or patent...

Layer ‐specific deformation analysis in severe aortic valve stenosis, primary mitral valve regurgitation, and healthy individuals validated against invasive hemodynamic measurements of heart function
ConclusionLayer‐specific myocardial strain (LSS) patterns differed in patients with severe AS, significant MR, and healthy individuals with highest values in MR. Strain irrespective of layer assessed was associated with LV wall stress but seemed less related to contractility and unrelated to stroke work in the setting of normal LVEF.

Reversing the Cardiac Effects of Sedentary Aging in Middle Age-A Randomized Controlled Trial: Implications For Heart Failure Prevention.
Conclusions - In previously sedentary healthy middle-aged adults, 2 years of exercise training improved maximal oxygen uptake and decreased cardiac stiffness. Regular exercise training may provide protection against the future risk of heart failure with a preserved ejection fraction by preventing the increase in cardiac stiffness attributable to sedentary aging.

Left ventricular end-diastolic dimension and septal e ′ are predictors of cardiac index at rest, while tricuspid annular plane systolic excursion is a predictor of peak oxygen uptake in patients with pulmonary hypertension
AbstractLittle is known regarding a correlation of hemodynamics at rest or exercise capacity with echocardiographic parameters in patients with pulmonary hypertension (PH). To clarify these potential correlations, we performed transthoracic echocardiography, right heart catheterization, and cardiopulmonary exercise testing in 53 patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Left ventricular end-diastolic dimension (LVDd), early diastolic velocity of the septal mitral annulus (septal e ′), tricuspid regurgitation peak gradient (TRPG), and tricuspid annular p...

The Prognostic Value of Follow-up Hemodynamic Variables After Initial Management in Pulmonary Arterial Hypertension.
Conclusions -SVI and RAP were the hemodynamic variables independently associated with death or lung transplantation at first follow-up RHC after initial PAH treatment. These findings suggest that the SVI could be a more appropriate treatment target than the cardiac index in PAH.

Right Ventricular Function Is Strongly Correlated With a Right Heart-Pulmonary System Rather Than With Right Ventricular Contractility
Background: RV function is a major determinant of clinical presentation in pulmonary hypertension. However, both of RVEF (MRI) and RVFAC (echocardiography) are highly load-dependent, and do not reflect RV contractility. Purpose: The aim of this study is to investigate the physiological correlates between RVFAC, RV contractility, RV afterload, and RV-PA coupling. Methods: Consecutive patients with PH who underwent RV catheterization and routine echocardiography were enrolled. RV afterload is estimated by arterial elastance (Ea), a ratio of end-systolic pressure to stroke volume.

Super High Dose Beta-blocker Administration for the Patients with Dilated Cardiomyopathy
First case is a 25-year-old female with dilated cardiomyopathy. Left ventricular end-diastolic diameter (LVEDD) was 74 mm and ejection fraction (EF) was 29%. Carvedilol was already uptitrated to 20 mg twice daily. Right heart catheterization (RHC) revealed very low cardiac output (C.O. 2.82 l/min), cardiac index (C.I. 1.47 l/min/m2), stroke volume (SV 29 ml) and rapid heart rate (HR 96/min) despite maximu m dosage of carvedilol in Japan. Carvedilol was uptitrated to 50 mg twice daily and additional 10 mg bisoprolol twice daily was started under administration of low-dose dobutamine.

Utility and Feasibility of Right Ventricular Strain of a Line Segment in Patients Referred for Left Ventricular Assist Device
Background: Right ventricular (RV) longitudinal strain (LS) is reported to correlate with RV stroke work index (RVSWI) which is a predictor of RV failure after LVAD implantation. However, RVLS occasionally cannot be analyzed in dilated hearts. Purpose: To test the utility and feasibility of a novel parameter, RV strain of a line segment (RVSLS), in patients undergoing LVAD. Methods: Twenty-two heart failure patients underwent right heart catheterization and speckle-tracking echocardiography before and after LAVD implantation.
