Management Of Aortic Insufficiency In Patients With Left Ventricular Assist Device ̶ A Retrospective Analysis, Hartmuth B. Bittner

The VAD Journal

Background: Aortic insufficiency is increasingly recognized as a complication of left ventricular assist device (LVAD) support and may lead to clinical decompensation requiring correction. This article describes experiences in managing patients presenting with concomitant aortic insufficiency and with de novo aortic insufficiency following left ventricular assist device implantations.

Methods: All patients undergoing LVAD implantation between 2012 and 2014 were included in this retrospective analysis if aortic valve insufficiency was present on implantation or newly developed (de novo) after implantation. Moderate to severe aortic valve insufficiency was corrected at implantation.

Results: The data of 39 patients were included. At the time …

Guidewire Method For Measuring Local Left Ventricular Electrical Activation Time During Cardiac Resynchronization Implantation., Seth J Rials, Michele Pershing, Christy Collins

OhioHealth Research Institute Articles

The timing of local activation at left ventricular (LV) pacing leads is measured from the onset of the QRS complex to the peak of the LV electrogram (QLV). Pacing from the sites of late activation is associated with higher response rates to cardiac resynchronization therapy (CRT). Prior studies have measured QLV from permanent pacing leads, or have used electroanatomic mapping systems. The current study compares QLV measurements made with a guidewire to those collected from permanent LV pacing leads positioned at the same venous site without the use of electroanatomic mapping systems. In this study, 20 patients undergoing CRT implantation …

Deciphering A Case Of Pulmonary Hypertension In A Young Female: Partial Anomalous Pulmonary Venous Drainage The Culprit, Hiten R. Patel, Suchit Bhutani, Fayez Shamoon, Hartaj Virk

Abington Jefferson Health Papers

Partial anomalous pulmonary venous drainage (PAPVD) is a rare congenital cardiac defect and is associated with sinus venosus atrial septal defect. While most cases are asymptomatic, a patient can present with pulmonary hypertension (PHTN) and it can be difficult to diagnose. Here, we discuss the case of a young female with PHTN who was found to have two right-sided PAPVD. Through this case, authors try to emphasize the importance of meticulous and thorough investigation when evaluating PHTN, which allows for correct diagnosis and a timely intervention before PHTN becomes irreversible.

Unresponsive Patient With Lvad: A Case Series, Ameer Z. Musa, Julia Akhtarekhavari

The VAD Journal

Mechanical circulatory support (MCS) for patients with advanced heart failure (HF) is becoming more commonplace as technology has progressed and reliability of these systems has improved. We report our experience with three patients with cardiopulmonary arrest in the hospital and propose a protocol for the prompt assessment and treatment of an unresponsive patient with a LVAD in place. We presented three cases of unresponsive patients on LVAD support with low flow or no flow through the LVAD. Although all three of them were alive after resuscitation, none survived to discharge. In all three cases, there were no flaws in LVAD …

Relationship Of Transmural Variations In Myofiber Contractility To Left Ventricular Ejection Fraction: Implications For Modeling Heart Failure Phenotype With Preserved Ejection Fraction, Yanghoub Dabiri, Kevin L. Sack, Semion Shaul, Partho P. Sengupta, Julius M. Guccione

Faculty & Staff Scholarship

The pathophysiological mechanisms underlying preserved left ventricular (LV) ejection fraction (EF) in patients with heart failure and preserved ejection fraction (HFpEF) remain incompletely understood. We hypothesized that transmural variations in myofiber contractility with existence of subendocardial dysfunction and compensatory increased subepicardial contractility may underlie preservation of LVEF in patients with HFpEF. We quantified alterations in myocardial function in a mathematical model of the human LV that is based on the finite element method. The fiber-reinforced material formulation of the myocardium included passive and active properties. The passive material properties were determined such that the diastolic pressure-volume behavior of the LV …

Quantum confined materials have been extensively studied for photoluminescent applica- tions. Due to intrinsic limitations of low biocompatibility and challenging modulation, the utilization of conventional inorganic quantum confined photoluminescent materials in bio- imaging and bio-machine interface faces critical restrictions. Here, we present aromatic cyclo-dipeptides that dimerize into quantum dots, which serve as building blocks to further self-assemble into quantum confined supramolecular structures with diverse morphologies and photoluminescence properties. Especially, the emission can be tuned from the visible region to the near-infrared region (420 nm to 820 nm) by modulating the self-assembly process. Moreover, no obvious cytotoxic effect is observed for …

Experimental Intravascular Hemolysis Induces Hemodynamic And Pathological Pulmonary Hypertension: Association With Accelerated Purine Metabolism, Victor P. Bilan, Frank Schneider, Enrico M. Novelli, Eric E. Kelley, Sruti Shiva, Mark T. Gladwin, Edwin K. Jackson, Stevan P. Tofovic

Faculty & Staff Scholarship

Pulmonary hypertension (PH) is emerging as a serious complication associated with hemolytic disorders, and plexiform lesions (PXL) have been reported in patients with sickle cell disease (SCD). We hypothesized that repetitive hemolysis per se induces PH and angioproliferative vasculopathy and evaluated a new mechanism for hemolysis-associated PH (HA-PH) that involves the release of adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP) from erythrocytes. In healthy rats, repetitive admin- istration of hemolyzed autologous blood (HAB) for 10 days produced reversible pulmonary parenchymal injury and vascular remodeling and PH. Moreover, the combination of a single dose of Sugen-5416 (SU, 200mg/kg) and 10-day …

Faculty & Staff Scholarship

Background: Acute hyperglycemia is associated with worse outcomes in diabetic patients admitted with ST‐eleva‐ tion myocardial infarction (STEMI). However, the impact of full‐scale decompensated diabetes on STEMI outcomes has not been investigated.

Methods: We utilized the national inpatient sample (2003–2014) to identify adult diabetic patients admitted with STEMI. We defined decompensated diabetes as the presence of diabetic ketoacidosis (DKA) or hyperglycemic hyper‐ osmolar state (HHS). We compared in‐hospital morbidity and mortality and cost between patients with and without diabetes decompensation before and after propensity‐score matching.

Results: A total of 73,722 diabetic patients admitted with STEMI were included in the study. …

Optimal Scene Time To Achieve Favorable Outcomes In Out-Of-Hospital Cardiac Arrest: How Long Is Too Long?, Glenn Goodwin, Dyana Picache, Brian J. Louie, Nicholas Gaeto, Tarik Zeid, Paxton P. Aung, Sonu Sahni

Touro College of Osteopathic Medicine (New York) Publications and Research

Despite advances in resuscitation science and public health, out-of-hospital cardiac arrest (OOHCA) cases have an average survival rate of only 12% nationwide, compared to 24.8% of cases occurring in hospital. Many factors, including resuscitation interventions, contribute to positive patient outcomes and have, therefore, been studied in attempts to optimize emergency medical services (EMS) protocols to achieve higher rates of return of spontaneous circulation (ROSC) in the field. However, no consensus has been met regarding the appropriate amount of time for EMS to spend on scene.

Hydrogen sulfide (H2S) has emerged as an important physiological and pathophysiological signaling molecule in the cardiovascular system influencing vascular tone, cytoprotective responses, redox reactions, vascular adap- tation, and mitochondrial respiration. However, bioavailable levels of H2S in its various biochemical metabolite forms during clinical cardiovascular disease remain poorly understood. We performed a case-controlled study to quantify and compare the bioavailability of various biochemical forms of H2S in patients with and without cardiovascular disease (CVD). In our study, we used the reverse-phase high performance liquid chromatography monobromobimane assay to analytically measure bioavailable pools of H2S. Single nucleotide polymorphisms (SNPs) were also identified …

Journal Articles

© 2018 American Society of Extra-Corporeal Technology. All Rights Reserved. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an invaluable rescue therapy for patients suffering from cardiopulmonary arrest, but it is not without its drawbacks. There are cases where patients recover their cardiac function, yet they fail to wean to mechanical conventional ventilation (MCV). The use of high-frequency percussive ventilation (HFPV) has been described in patients with acute respiratory failure (RF) who fail MCV. We describe our experience with five patients who underwent VA-ECMO for cardiopulmonary arrest who were successfully weaned from VA-ECMO with HFPV after failure to wean with MCV. Weaning …

Digital Stethoscope: Technology Update, S. Swarup, A. N. Makaryus

Journal Articles

© 2018 Swarup and Makaryus. Cardiovascular disease (CVD) is recognized as the leading cause of mortality throughout the world. About one-third of global mortality is attributable to CVD. In addition to clinical presentation, specific clinical exam findings can assist in treating and preventing CVD. CVD may initially manifest as pulmonary pathology, and thus, accurate cardiopulmonary auscultation is paramount to establishing accurate diagnosis. One of the most powerful tools available to physicians is the stethoscope. The stethoscope first emerged in the year 1818, invented by a French physician, René Laennec. Since then, the initial modest monaural wooden tube has evolved into …
