Elizabeth S Ellent, Ronald Chong-Yik, Abdul Mukhtadir Khan
BACKGROUND: Cardiac angiosarcomas are an extremely rare tumor with an incidence of only 0.056%. Diagnosing this rare tumor becomes even more difficult as the presentation of cardiac angiosarcomas varies based on anatomic location. Depending on the tumor's proximity to valves, symptoms may be more consistent with heart failure, while growth throughout the conduction system may produce arrhythmias. CASE REPORT: We present the case of a young male with a significant tumor burden of cardiac angiosarcoma in his lungs whose symptoms included pleuritic chest pain and hemoptysis...

Dawn S Hui, Fernando Fleischman, P Michael McFadden
BACKGROUND: Thromboembolism-in-transit straddling a patent foramen ovale (PFO) is a rare condition that requires urgent surgical intervention to prevent arterial emboli. CASE REPORT: We present the case of a 42-year-old female who presented with a symptomatic pulmonary embolism. Echocardiography identified a PFO, with a bridging thrombus-in-transit and evidence of right ventricular strain. Urgent surgery was performed because of the risk of systemic embolism. A large thrombus was identified during biatrial exploration...

Tariq Yousuf, Jason Kramer, Brody Jones, Hesam Keshmiri, Muhyaldeen Dia
BACKGROUND: Heterotaxy syndrome, also called isomerism, is a condition in which abdominal and thoracic organs are located in abnormal body positions. Pulmonary hypertension (PHTN) is an uncommon clinical feature of heterotaxy syndrome. CASE REPORT: We describe the case of a 26-year-old male who developed PHTN as a rare manifestation of heterotaxy syndrome. To our knowledge, PHTN has never been reported as a prominent clinical feature in a patient with heterotaxy syndome and congenital cardiac abnormalities...

REVIEW
Patricia E Thomas, Scott L Macicek
BACKGROUND: Catheter ablation has been used to manage supraventricular arrhythmia in children since 1990. This article reviews the history of catheter ablation used to treat arrhythmia in children and discusses new frontiers in the field. We also address ablation in adult patients with a history of congenital heart disease (CHD) that was diagnosed and initially treated in childhood. METHODS: We conducted an evidence-based literature review to gather available data on ablation for supraventricular tachycardia in children and adult patients with CHD...

BACKGROUND: Heart disease is a major cause of death in industrialized nations, with approximately 50% of these deaths attributable to sudden cardiac arrest. If patients at high risk for sudden cardiac arrest can be identified, their odds of surviving fatal arrhythmias can be significantly improved through prophylactic implantable cardioverter defibrillator placement. This review summarizes the current knowledge pertaining to surface electrocardiogram (ECG) predictors of sudden cardiac arrest...

REVIEW
Salima Qamruddin
BACKGROUND: Stress echocardiography is an integral test in the cardiac diagnostic laboratory and has high sensitivity and specificity. Despite the excellent specificity of stress echocardiography, we continue to see a subset of patients with false-positive tests (defined as <50% diameter stenosis on subsequent coronary angiography). These false-positive findings present a management challenge because it remains unclear if and how to treat these patients. METHODS: This article reviews relevant clinical studies and their outcomes...

REVIEW
Merrill H Stewart, J Stephen Jenkins
BACKGROUND: Mitral regurgitation (MR) is the second leading cause of valvular heart disease in the United States behind aortic stenosis. The percutaneous repair of the mitral valve (MitraClip, Abbott, Inc.) has been approved in the United States since 2013 as an alternative to traditional mitral valve surgery. However, many questions are left unanswered about when to perform this procedure and whom to perform it on. METHODS: We reviewed major published literature on the MitraClip from 2003-2016 to help guide clinical decision-making...

REVIEW
Joseph A R Englert, Jennifer A Davis, Selim R Krim
BACKGROUND: Heart transplantation remains the definitive therapy for patients with advanced heart failure; however, owing to limited donor organ availability and long wait times, continuous-flow left ventricular assist devices (LVADs) have become standard therapy. METHODS: This review summarizes the history, progression, function, and basic management of LVADs. Additionally, we provide some clinical pearls and important caveats for managing this unique patient population...

REVIEW
Stacy A Mandras, Hector O Ventura, Paul A Corris
BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare and fatal disease. While many treatment options have been shown to improve quality of life, exercise tolerance, and hemodynamics in PAH, survival remains poor, in part due to the advanced stage at which patients present to PAH specialists. METHODS: This perspective paper explores challenges related to the timing of referral, diagnosis, and initiation of therapy. RESULTS: Multiple factors account for the delay in referral, including fallacies in physician education, commercial influence resulting in inappropriate prescribing practices, and barriers in access to care...

REVIEW
Jean Domercant, Nichole Polin, Eiman Jahangir
BACKGROUND: Cardio-oncology is a collaborative approach between cardiologists and oncologists in the treatment of patients with cancer and heart disease. Radiation and chemotherapy have played a major role in the decreased cancer-related mortality achieved in the past 2 decades. However, anthracycline-, tyrosine kinase-, and radiation-based therapies are each associated with independent cardiovascular (CV) risks, and these risks are cumulative when these therapies are used in combination...

REVIEW
Michael L Bernard
BACKGROUND: Worldwide, more than 700,000 pacemakers are implanted annually with more than 250,000 implanted in the United States. Since the first fully transvenous pacemaker implantations in the early 1960s, great technologic advances have been made in pacing systems. However, the combination of subcutaneous pulse generators and transvenous pacing leads has remained constant for more than 50 years. Leadless pacing systems offer an alternative to traditional pacing systems by eliminating the need for permanent transvenous leads while providing therapy for patients with bradyarrhythmias...

BACKGROUND: Inadequate patient adherence to a medication regimen is a major factor in the lack of success in treating hyperlipidemia. Improved adherence rates may result in significantly improved cardiovascular outcomes in populations treated with lipid-lowering therapy. The purpose of this metaanalysis was to evaluate the effectiveness of interventions aimed at improving adherence to lipid-lowering drugs, focusing on measures of adherence and clinical outcomes. METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature databases through January 14, 2015, and also used the results from previous Cochrane reviews of this title...
