A Case Of A Massive Right Atrial Thrombus Removal Under Transesophageal Echocardiographic Guidance, Justin Phillips, Max Kabolowsky, Alex M. Hendon, Samantha Arzillo

HCA Healthcare Journal of Medicine

Background

With the advent of catheter guided interventions, practitioners have added another tool alongside chemical lysis and surgical removal to reduce the clot burden of patients with large emboli and thrombi. Due to comorbid conditions, many patients are poor candidates for surgical or chemical clot treatment but may present optimally for catheter-based thromboembolectomy. In this case, we highlight the benefits of mechanical thrombectomy with transesophageal echocardiographic guidance to reduce the clot burden of a patient who would otherwise be considered a poor candidate for surgical or chemical treatment.

Case Presentation

This case follows a 78-year-old man with a past medical …

Coronary Artery Calcium Scoring In Asymptomatic Patients, Bilal Hussain, Ahmed Mahmood, Michael G. Flynn, Thomas Alexander

HCA Healthcare Journal of Medicine

Coronary artery calcium (CAC) scoring is an important prognostic tool for personalized cardiovascular preventive care and has recently been incorporated into American College of Cardiology/American Heart Association guidelines. CAC provides direct visualization and quantification of CAC burden for risk stratification and primary prevention of cardiovascular events in an asymptomatic population. CAC scoring is recommended for individuals with intermediate 10-year atherosclerotic cardiovascular disease (ASCVD) risk and selective populations with borderline ASCVD risk. In this review, we outline the interpretation of CAC scores for predicting the risk of cardiovascular events, and we highlight the guidelines for starting statin and potentially starting aspirin …

Atrial Fibrillation: Rate Versus Rhythm Control, Carlos E. Vargas, Mina Bhatnagar, Haris Ahmed, Michael G. Flynn, Thomas Alexander

HCA Healthcare Journal of Medicine

Atrial fibrillation (AF) remains the most common arrhythmia worldwide and is expected to affect approximately 12 million individuals in the United States alone by 2030. Thromboembolic events remain a feared complication of AF and should be treated and risk-stratified utilizing the CHA₂DS₂-VASc scoring system. Other complications of AF span a wide spectrum from impaired quality of life (QoL) to an increase in all-cause mortality. Rate control strategies consist of controlling the ventricular rate and have been shown to be a safe and effective strategy for asymptomatic AF patients. In patients who are plagued with symptoms leading to impaired QoL or …

An Assessment Of The Diagnostic Value In Syncope Workup: A Retrospective Study, Ashan T. Hatharasinghe, Kayvon Etebar, Ryan Wolsky, Hossein Akhondi, Napatkamon Ayutyanont

HCA Healthcare Journal of Medicine

Background

Patients with syncope often undergo costly testing, despite current guidelines and data supporting the contrary.

Objective

To determine the diagnostic value through positivity rate of electrocardiogram (EKG), computed tomography (CT) of the brain, magnetic resonance imaging (MRI) of the brain, transthoracic echocardiogram, nuclear and pharmacologic cardiac stress test, tilt table test and carotid ultrasound in patients diagnosed with syncope.

Methods

This is a retrospective study of 10,036 adults presenting to the emergency department or hospitalized with a primary diagnosis of syncope at 8 acute care facilities in the southwest United States from January 1, 2019, to December 31, 2019. …

Methamphetamine Associated Cardiomyopathy In Pregnancy: The Distinctions And The Implications, Ashan Hatharasinghe, Hossein Akhondi

HCA Healthcare Journal of Medicine

Introduction

Methamphetamine associated cardiomyopathy (MAC) and peripartum cardiomyopathy (PPCM) are both rare obstetric conditions. Literature regarding methamphetamine associated cardiomyopathy in the obstetric population is limited, and it can be difficult to make the distinction between the two given the similarities in clinical presentation. However similar, there are significant distinctions in the pathophysiology of these two that can help clinicians with the management process.

Clinical Findings and Outcomes

This case involves a 35-year-old Hispanic G6P5005 at 37 weeks gestation presenting with acute respiratory failure secondary to acute decompensated heart failure with reduced ejection fraction and superimposed preeclampsia leading to urgent cesarean …

Covid-19 And Arrhythmias: A Review Of Cardiac Electrophysiology Associated With Sars-Cov-2, Kashmala Khan, Francis Dimtri, Carlos Vargas, Thomas Alexander

HCA Healthcare Journal of Medicine

Coronavirus infectious disease 2019 (COVID-19) has become one of the most recognized viral illnesses to date. Most people infected with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) have a benign clinical course, but there have also been catastrophic outcomes. Although, notoriously known to affect the respiratory system, extra-pulmonary manifestations have also been established. An increasing number of people have been reported to present with cardiac manifestations, which include but are not limited to arrhythmias. The cardiac conduction system can be damaged by various mechanisms in patients infected with SARS-CoV-2. In this review, we will attempt to briefly describe the arrhythmogenic …
