Sinoatrial nodal artery fistula to bronchial arteries originating from the right coronary artery in the setting of chronic bronchiectasis and coronary artery disease.

We present a 67-year-old male with past medical history of hyperlipidemia, hypertension, and emphysema, and who was a former smoker, with dyspnea on exertion and chest pain.

Profile of Patients Hospitalized for Heart Failure Who Leave Against Medical Advice.

Background: There is a paucity of information on patients hospitalized with heart failure (HF) who leave against medical advice (AMA). We sought to identify patient and hospital characteristics and outcomes of patients with HF who left AMA compared with those conventionally discharged to home.

Methods And Results: Using the Get With The Guidelines-Heart Failure registry, data were analyzed from January 2010 to June 2019.

Overview of Impella and mechanical devices in cardiogenic shock.

Introduction: Cardiogenic shock (CS) is a life-threatening condition associated with significant morbidity and mortality. The Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta.

Diagnostic Yield of Echocardiography in Syncope Patients with Normal ECG.

Aim. This study aimed to assess the role of echocardiography as a diagnostic tool in evaluating syncope patients with normal versus abnormal electrocardiogram. Methods.

Small Bowel Obstruction Mimicking Acute ST-Elevation Myocardial Infarction.

We present a case of a 42-year-old female who presented to our institution with a small bowel obstruction and had emergent surgical decompression. Thirteen days postoperatively, the patient became tachycardic and had worsening epigastric pain. Electrocardiogram showed significant ST-segment elevations in leads II, III, aVF, and V3-V6, suggesting the possibility of acute inferolateral myocardial infarction.

Clarithromycin-Induced Torsades de Pointes.

Acquired QT prolongation can be caused by cardiac and noncardiac medications. Macrolides are known to prolong QT interval. Rarely, it can be fatal.

Surgical ablation for atrial fibrillation: the efficacy of a novel bipolar pen device in the cardioplegically arrested and beating heart.

Objective: The introduction of ablation technology has simplified surgical intervention for atrial fibrillation. However, most ablation devices cannot create focal transmural lesions on the beating heart and have difficulty ablating specific regions of the atria, such as the atrioventricular isthmus, coronary sinus, and ganglionated plexus. The purpose of this study was to examine the efficacy of a pen-type bipolar radiofrequency ablation device on both arrested and beating hearts.

The effects of the Cox maze procedure on atrial function.

Objective: The effects of the Cox maze procedure on atrial function remain poorly defined. The purpose of this study was to investigate the effects of a modified Cox maze procedure on left and right atrial function in a porcine model.

Methods: After cardiac magnetic resonance imaging, 6 pigs underwent pericardiotomy (sham group), and 6 pigs underwent a modified Cox maze procedure (maze group) with bipolar radiofrequency ablation.
