The advancement of echocardiography in the past two decades is more than downsizing of the machines and improvement of image quality, but introduction of new imaging modalities leading to the ability of performing quantitative analysis. This function is greatly facilitated by the integration of echo machines with high performance computers, software programming and establishment of workstation for offline analysis. Today, echo examination is more than estimation of ejection fraction (EF) and patterns of left ventricular (LV) diastolic dysfunction...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

INTRODUCTION: Structural heart interventions are guided by transoesophageal or intracardiac echocardiography (TEE/ICE). MicroTEE, developed for paediatric purposes, is smaller and therefore less invasive and traumatic, avoiding the need for general anaesthesia. We aimed to show feasibility of procedural guidance by comparing image quality of microTEE with standard TEE and ICE during adult transcatheter interventions, and assess the accuracy in obtaining left atrial appendage (LAA) measurements between the microTEE probe and standard TEE...

Trans-oesophageal echocardiography (TOE) is frequently performed prior to atrial fibrillation (AF) ablation to exclude left atrial appendage (LAA) thrombus. However, patients undergoing AF ablation are usually anticoagulated, thus making the presence of thrombus unlikely in most cases. This study aimed to determine whether the CHA2DS2VASc scoring system can be used to identify patients that do not require TOE prior to AF ablation. In this single centre retrospective study, local institutional and primary care databases and electronic patient records were searched to identify patients that had undergone TOE prior to AF ablation...

Prosthetic valve endocarditis (PVE) is a serious infection with potentially fatal consequences. Early detection is crucial for successful management and outcome. The diagnosis of PVE is challenging and is based on the Duke criteria (DC) in which echocardiography plays a crucial role. However, transthoracic and transoesophageal echocardiography have less diagnostic value in PVE compared to native valve endocarditis. Combined computed tomography and fluorodeoxyglucose positron emission is a new technique providing improved diagnostic accuracy in PVE...

AIMS: We evaluated possible detrimental effects of transoesophageal echocardiography (TEE) on the oesophageal tissue during percutaneous mitral valve repair (PMVR). METHODS AND RESULTS: From March 2014 to July 2015, 186 patients were treated for severe mitral regurgitation (MR) with PMVR using the MitraClip® system. In 40 patients, esophagogastroduodenoscopy was performed due to symptoms related to the gastrointestinal tract. Based on the procedure's duration, patients were classified into group 1 (> 60 minutes, n=23) or into group 2 (< 60 minutes, n=17), respectively...

BACKGROUND: For some patients with atrial fibrillation, direct current cardioversion (DCCV) is one strategy that can be used to establish sinus rhythm but appropriate anticoagulation is mandatory to prevent thromboembolic events. Historically, patients were anticoagulated with warfarin with bridging with unfractionated or low molecular weight heparin, however, recently novel oral anticoagulants (NOACs), apixaban, dabigatran and rivaroxaban have become more popular. Despite the increase in use, real world data on safety and efficacy is limited...

OBJECTIVES: Accurate sizing of the left atrial appendage (LAA) is essential when performing percutaneous LAA closure. This study aimed to compare different LAA imaging modalities and sizing methods in order to obtain successful LAA closure. BACKGROUND: Percutaneous LAA closure is an increasingly used treatment strategy to prevent stroke in patients with atrial fibrillation. LAA sizing has typically been done by 2D-transoesophageal echocardiography (TEE). METHODS: Patients who had a preprocedural TEE and preprocedural and postprocedural multislice CT (MSCT) were identified...

INTRODUCTION: Retrievable inferior vena cava (IVC) filters have been increasingly used in patients with major trauma who have contraindications to anticoagulant prophylaxis as a primary prophylactic measure against venous thromboembolism (VTE). The benefits, risks and cost-effectiveness of such strategy are uncertain. METHODS AND ANALYSIS: Patients with major trauma, defined by an estimated Injury Severity Score >15, who have contraindications to anticoagulant VTE prophylaxis within 72 hours of hospitalisation to the study centre will be eligible for this randomised multicentre controlled trial...

Sub-aortic (SA) aneurysms are a rare entity of variable aetiology. We report the first case of a SA aneurysm assessed using cardiac magnetic resonance imaging (MRI). A 33-year-old female with human immunodeficiency virus and on highly active antiretroviral treatment presented with syncope and dyspnoea. Clinical examination suggested moderate to severe aortic regurgitation (AR) confirmed by transthoracic and transoesophageal echocardiograms. However, echocardiography was suboptimal in defining the precise mechanism and severity of AR...

Aims: To assess the association and the predictive value of plasma homocysteine (Hcy) levels with LA/LAA thrombus in non-valvular Atrial fibrillation (AF) patients with low CHA2DS2-VASc score. Methods and results: Eight hundred and eighty-eight consecutive patients in non-valvular AF with CHA2DS2-VASc score of 0 and 1 were enrolled. All patients routinely underwent transthoracic echocardiography and transoesophageal echocardiography. A total of thirty-two patients had LA/LAA thrombus...

Aims: Using balloon sizing to determine device size may cause complications and increase procedure time in performing transcatheter closure of atrial septal defect (ASD). We aimed to validate the clinical utility of a formula using measurements from 3D transoesophageal echocardiography (TOE) images in performing the procedure without balloon sizing. Methods and results: We enrolled 248 consecutive patients with ASD in a prospective registry. In the first tier (n = 53), we determined the device size before the procedure using our formula and performed balloon sizing during the procedure to verify our decision...

OBJECTIVES: This study aimed to compare the effects of hypothermic ventricular fibrillation and beating-heart techniques during cardiopulmonary bypass (CPB) on postoperative outcomes after simple pulmonary valve replacement in patients with repaired tetralogy of Fallot (TOF). METHODS: We retrospectively reviewed the data of 47 patients with repaired tetralogy of Fallot at a single institution, who received pulmonary valve replacement under the ventricular fibrillation or beating-heart technique without cardioplegic cardiac arrest during CPB between January 2005 and April 2015...

Background: General anaesthesia and surgically induced changes in cardiac loading conditions may alter flow across the aortic valve. This study examined how echocardiographic assessment of the severity of aortic stenosis (AS) changes during surgery. Methods: Patients who underwent aortic valve replacement for any severity of AS between July 2007 and June 2015 were identified. Peak velocities, mean gradients, and dimensionless indices (DI) measured with preoperative transthoracic echocardiography (TTE) were compared with those measured with intraoperative transoesophageal echocardiography (TOE)...

OBJECTIVES: Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. METHODS: Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015...
