BACKGROUND: We investigated whether both echocardiography and blood examination parameters obtained before discharge are more closely associated with adverse events than those obtained upon admission in hospitalized heart failure (HF) patients. METHODS: We retrospectively selected 267 hospitalized HF patients who underwent comprehensive transthoracic echocardiography (TTE) within 2 days of admission (n=223) and/or within 7 days of discharge (n=157). Blood test results were also collected at the same time window...

Arash Salemi, Berhane M Worku
Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

The history of echocardiography is sprinkled with many interesting episodes and anecdotes showing that devoting your life to the pursuit of one goal is praiseworthy, and that at the same time, a little luck goes a long way. Transthoracic echocardiography (TTE) has led to dramatic improvements in cardiovascular medicine, and is now the most widely used diagnostic cardiac test after electrocardiography (ECG). The present review pays tribute to the pioneering efforts of those who believed in this innovative technology despite mounted skepticism and briefly describes the evolution of TTE from its early days to the most recent developments...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

Introduction: Traditional graded-exercise tests to volitional exhaustion (GXTs) are limited by the need to establish starting workloads, stage durations, and step increments. Short-duration time-trials (TTs) may be easier to implement and more ecologically valid in terms of real-world athletic events. The purpose of the current study was to assess the reliability and validity of maximal oxygen uptake ([Formula: see text]max) and performance measured during a traditional GXT (STEP) and a four-minute running time-trial (RunTT)...

BACKGROUND: Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. METHODS: The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access...

Aluminium phosphide (ALP) is widely used as a fumigant pesticide. In case of ALP poisoning, it is responsible for myocardial dysfunction, related to toxic myocarditis, and hemodynamic disorders. We report a case of a 28-year-old female who had intentionally ingested ALP and was admitted with cardiogenic shock. The transthoracic echocardiography (TTE) at the time of admission showed severe global myocardial hypokinesia with the presence of a giant left ventricular thrombus. Cardiovascular magnetic resonance (CMR) revealed extensive toxic myocarditis with a left ventricular systolic dysfunction...
