An Observational Comparison Of Distal Radial And Traditional Radial Approaches For Coronary Angiography, Anupam Bhambhani, Salil Pandey, Aditi N. Nadamani, Kartikey Tyagi

Journal of the Saudi Heart Association

Background: Several studies have recently reported regarding feasibility and safety of distal transradial access (d-TRA) in the anatomical snuff-box (ASB); however, literature comparing it with the conventional TRA at the wrist (w-TRA) is sparse. This study compares the technical efficiency and safety of ASB and wrist approaches for TRA for coronary angiography (CAG) and evaluates the radial artery (RA) anatomy at these sites. Methods: Two hundred consecutive patients undergoing CAG via w-TRA or d-TRA (100 in each group) were investigated. The primary endpoint was comparison of procedural efficiency of the two methods, defined as CAG completion from the intended access …

Occurence Of Left Main Occlusion On Tuesday: Chronobiology Of Acute Myocardial Infarction, Gianluca Rigatelli, Marco Zuin

Journal of the Saudi Heart Association

Objectives: The existence of a “weekend effect” for onset of acute myocardial infarction (AMI) has been suggested in the past, but the relation with the culprit vessel has not been investigated. MI due to left main coronary artery lesion represents a particularly serious life-threatening condition. Our study was aimed to assess the chronobiology of admission to the emergency department for AMI considered to be induced by a left main culprit lesion. Methods: We retrospectively reviewed patients who experienced an AMI due to a left main culprit lesion between January 1, 2008 and January 1, 2018 stratifying them according to the …

A Real-Life Correlation Between Clinical Syntax Score Ii And Carotid Intima-Media Thickness In Patients With Stable Coronary Artery Disease, Mahmoud Abdelnabi, Abdallah Almaghraby, Ozge O. Tok, Tugba K. Oz, Yehia Saleh, Ahmed Morsi, Hiatham Badran

Journal of the Saudi Heart Association

Background: SYNTAX score II (SSII) is an update of the established SYNTAX score (SS) that uses clinical variables such as age, sex, creatinine clearance, left ventricular ejection fraction, chronic obstructive pulmonary disease, and peripheral arterial disease. Furthermore, SSII has been proven to be a more powerful predictive tool than SS in patients with complex coronary artery disease (CAD). Carotid õntima-media thickness (CIMT) is a widely used noninvasive evidence for subclinical or early atherosclerosis, and it was proved to be an independent predictor for cardiovascular events. Most of the previously published articles studied the association between the CIMT with old cardiovascular …

Effect Of Lifestyle Modifications On Blood Pressure And Bmi In Overweight Or Obese Adults With Primary Hypertension, Mariska Vandenbergh

Evidence-Based Practice Project Reports

Hypertension (HTN) and obesity contribute to poor cardiovascular outcomes which can be managed with diet and exercise lifestyle changes. In addition, self-awareness (SA) of eating patterns can be a useful tool to promote adherence to lifestyle changes. The purpose of this project was to determine the effect of lifestyle education, the DASH diet, and tools to increase SA for adult clinic patients who were overweight with hypertension. The REAP and PIH tools were utilized to increase patients’ SA of their diagnosis and current dietary habits. A literature search over five databases was conducted and analyzed thoroughly. National guidelines strongly recommend …

Implementation Of Peer Support And Shared Decision-Making Aids For The Transcatheter Aortic Valve Replacement Population, Kimberlee Einfeld

Doctor of Nursing Practice Projects

Background: Patients at a community hospital verbalized fear, stress and anxiety about transcatheter aortic valve replacement (TAVR). Patients with aortic stenosis eligible for TAVR may experience low self-efficacy and anxiety while considering valve replacement which may lead to poor quality of life, interfere with understanding information from medical providers, and other health complications.

Methods: All patients eligible for TAVR between June and August of 2019 were invited to participate in a pilot project using peer support and use of shared decision-making (SDM) aids. Former TAVR patients were trained to be Mended Hearts TAVR peer volunteers. Participants were connected by telephone …

Modulating The Rate Of Fibrin Formation And Clot Structure Attenuates Microvascular Thrombosis In Systemic Inflammation, Christian Valladolid, Marina Martinez-Vargas, Nitin Sekhar, Fong Lam, Cameron Brown, Timothy Palzkill, Alexander Tischer, Mathew Auton, K Vinod Vijayan, Rolando E Rumbaut, Trung C Nguyen, Miguel A Cruz

Faculty, Staff and Students Publications

Systemic inflammation can lead to coagulopathy and disseminated intravascular coagulation (DIC). In prior studies, the recombinant A2 domain of human von Willebrand factor (VWF; A2 protein) attenuated DIC and decreased mortality in lipopolysaccharide (LPS)-treated mice. Here, we performed studies to dissect the mechanism by which the A2 protein moderates DIC. We used confocal microscopy to analyze the fibrin clot structure in plasma from healthy humans and endotoxemic mice, turbidity assays to examine fibrin polymerization, and a murine model for LPS-induced DIC and introduced a loss-of-function mutation into the A2 protein for fibrin. The mutation of the residue E1567 located in …

Giant Left Main Coronary Artery Aneurysm Presenting As Multiple Implantable Cardioverter Defibrillator Shocks, Yury Malyshev, Asma Syed, Ricardo Castillo, Rumman A Syed, Sonu Sahni

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

Giant aneurysms of the left main coronary artery are one of the rarest findings in cardiology, encountered in less than 0.02% of patients. The presentation is usually the same as coronary artery disease since most coronary aneurysms in the western world are associated with atherosclerosis. Here we report the first case of giant aneurysm of the left main coronary artery presenting as ventricular tachycardia with multiple shocks of the defibrillator in a 57-year-old man with heart failure. We also review the etiology, pathology, and management of coronary aneurysms.

Tetralogy Of Fallot: A Clinical Review, Jacob Wooten, Joshua Bahos Silva

Student Scholar Showcase

Tetralogy of Fallot is a congenital heart disease that is associated with structural abnormalities during fetal development 1. The incidence of Tetralogy of Fallot in the United States is approximately 3-5 cases per 10,000 live births and is considered one of the most common cyanotic congenital heart diseases 2. The exact etiology of Tetralogy of Fallot is unknown, however it is thought to be associated with untreated maternal diabetes, maternal use of retinoids, as well as chromosomal abnormalities 2. The main components of this disease state include a right ventricular outflow obstruction, interventricular communication in the form of a ventricular …

Objective: Myocarditis, inflammation of the heart muscle, is an autoimmune heart disease that can be caused by viruses, bacteria and toxins. Myocarditis can lead to dilated cardiomyopathy (DCM) and heart failure. Currently there are no disease-specific therapies for treating myocarditis or preventing progression to DCM. Adipose Extracellular Vesicles (AEVs) are lipid bilayer nanoparticles that are released into the outside environment of adipocytes and provide promising regenerative potential for inflammatory diseases like myocarditis.

Methods: Lipoaspirate was obtained from women and men and AEVs isolated from the lipoaspirate using tangential flow filtration. We injected wild type male BALB/c mice with 250uL AEVs …

How Rare Is Isolated Rheumatic Tricuspid Valve Disease?, Edme R. Mustafa, Octavian Istrătoaie, Roxana Mandia, Georgică C. Târtea, Cristina Florescu

Journal of Mind and Medical Sciences

The incidence of rheumatic fever (RF) has markedly decreased in Europe since the beginning of the 20th century due to improved living conditions, early antibiotic therapy in streptococcal pharyngitis, and changes in serotypes of circulating streptococci. Isolated outbreaks of RF are still found in various parts of the world and the disease has changed its presentation with milder joint symptoms and subclinical carditis that make the correct diagnosis more difficult. Patients can present many years later with severe valve disease and significant disability. This article presents a case of isolated rheumatic tricuspid valve disease that presented with signs and symptoms …

Modified Danielson Technique For Prosthetic Aortic Valve Endocarditis And Aortoventricular Discontinuity, Gianfranco Filippone, Claudia Calia, Mario Finazzo, Fabio Fazzari, Giovanni Caruana, Vincenzo Argano

The Texas Heart Institute Journal

Endocarditis is a devastating complication of prosthetic aortic valve replacement. The infective process can destroy aortic annulus tissue, making conventional surgical valve replacement difficult or impossible and causing aortoventricular discontinuity. Several treatment techniques have been proposed. One of these, the Danielson technique, involves translocating the aortic valve to the native ascending aorta, débriding the abscess cavity, closing the coronary ostia, and bypassing the coronary arteries with a Y anastomosis between 2 vein grafts. We describe our use of a modified Danielson technique in a 68-year-old man with advanced prosthetic valve endocarditis that was associated with aortic annulus destruction and aortoventricular …

Robotic-Assisted Percutaneous Coronary Intervention Through Transradial Approach: Experience In 4 Patients With Complex Lesions, Amornpol Anuwatworn, Muhammad Ali Kahn, Tomasz Stys, Marian Petrasko, Adam Stys

The Texas Heart Institute Journal

Robotic-assisted percutaneous coronary intervention can reduce the exposure of interventional cardiologists to radiation and minimize the risk of occupational orthopedic injuries from wearing heavy protective aprons. The PRECISE (Percutaneous Robotically-Enhanced Coronary Intervention) study showed the efficacy and safety of robotic-assisted procedures for relatively low-risk lesions in single coronary arteries. Several reports have described robotic-assisted treatment of complex high-risk lesions, mostly through the transfemoral approach. We report 4 cases of patients in whom we used the transradial approach to treat complex lesions in the left anterior descending coronary artery with bifurcation balloon angioplasty reconstruction (2 cases), in the ostium of the …

Histologic Abnormalities Of The Ascending Aorta: Effects On Aortic Remodeling After Intracardiac Repair Of Tetralogy Of Fallot, Ujjwal Kumar Chowdhury, Lakshmi Kumari Sankhyan, Sheil Avneesh, Ruma Ray, Mani Kalaivani, Suruchi Hasija, Abhinavsingh Chauhan

The Texas Heart Institute Journal

We evaluated aortic tissue specimens from patients undergoing tetralogy of Fallot repair, to determine whether histologic abnormalities affect postsurgical aortic remodeling and other patient-related variables.

Using light microscopy, we studied full-thickness aortic wall tissue operatively excised from 118 consecutive patients undergoing intracardiac repair of tetralogy of Fallot. We performed multiple linear regression analysis to identify independent predictors of change in aortic root dimensions, which we measured with echocardiography after repair and every 3 months thereafter.

Thirty histologically normal specimens were used as controls. Elastic fiber fragmentation was found in 74.6% of the abnormal specimens, mucoid extracellular matrix accumulation in 49.2%, …

Speckle-Tracking Echocardiography In Cardio-Oncology And Beyond, Raymundo A Quintana, Linh P Bui, Rohit Moudgil, Nicolas Palaskas, Saamir Hassan, Jun-Ichi Abe, Elie Mouhayar, Syed Wamique Yusuf, Antonieta Hernandez, Jose Banchs

The Texas Heart Institute Journal

Speckle-tracking echocardiography has enabled clinicians to detect changes in myocardial function with more sensitivity than that afforded by traditional diastolic and systolic functional measurements, including left ventricular ejection fraction. Speckle-tracking echocardiography enables evaluation of myocardial strain in terms of strain (percent change in length of a myocardial segment relative to its length at baseline) and strain rate (strain per unit of time). Both measurements have potential for use in diagnosing and monitoring the cardiovascular side effects of cancer therapy. Regional and global strain measurements can independently predict outcomes not only in patients who experience cardiovascular complications of cancer and cancer …
