Aims: Long-term freedom from atrial fibrillation (AF) after catheter ablation (CA) and consequently the potential for stroke reduction remain unpredictable. Percutaneous left atrial appendage closure (LAAC) is an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. This study aims to evaluate long-term clinical results of combined CA and LAAC in one single procedure. Methods and results: Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective compilation of independent prospective general LAAC registries at the individual centres...

Percutaneous approaches to treat structural heart diseases are growing in number and complexity. Multimodality imaging is essential for planning and monitoring such interventions. The combination of three-dimensional transoesophageal echocardiography with fluoroscopy is the cornerstone of interventional imaging. However, these two modalities are displayed on separate screens, and are handled by different physicians, which requires a complex mental reconstruction for the interventional team. To overcome this issue, echocardiographic-fluoroscopic fusion imaging has been introduced recently in clinical practice...

BACKGROUND: Despite technological advances, studies continue to report high complication rates for atrial fibrillation (AF) ablation. We sought to review complication rates for AF ablation at a high-volume centre over a 14-year period and identify predictors of complications. METHODS: We reviewed prospectively collected data from 2750 consecutive AF ablation procedures at our institution using radiofrequency energy (RF) between January 2004 and May 2017. All cases were performed under general anaesthetic with transoesophageal echocardiography (TEE), 3D-mapping and an irrigated ablation catheter...

Transapical transcatheter aortic valve implantation is a well-established alternative in patients at a high risk for conventional aortic valve replacement. We performed transapical transcatheter aortic valve implantation on an 83-year-old woman with symptomatic severe aortic stenosis. Intraoperative transoesophageal echocardiography (TOE) after transcatheter aortic valve implantation showed mild mitral regurgitation without intracardiac structural injury. In the intensive care unit, the patient gradually had haemodynamic instability; TOE revealed severe mitral regurgitation with A2 and A3 prolapse due to rupture of the posterior papillary muscle...

Successful mitral valve (MV) repair for degenerative mitral regurgitation (DMR) is mainly related to surgical expertise and MV anatomy. Although 2D echocardiography, specifically transoesophageal (TOE), provides precise information regarding MV anatomy, recent advancements in matrix technology meant a decisive step forward to the point where segmental MV analysis can be accurately performed from a noninvasive 3D transthoracic (TTE) approach. The aims of this study were: (a) to evaluate the feasibility and time required for real-time 3D TTE in a large consecutive cohort of patients with severe DMR in the assessment of MV anatomy; (b) to compare the accuracy of 3D TTE and 2D TOE versus surgical inspection in the recognition and localization of all components of the MV leaflets; (c) to establish the added diagnostic value of 3D colourDoppler examination to pure 3D morphologic evaluation...

The European Society of Cardiology (ESC) guidelines for management of atrial fibrillation (AF) recommend the use of CHA2DS2VASc risk score for assessment of thromboembolic (TE) risk, whereas the stratification of bleeding risk should be obtained by HAS-Bleed to balance the most appropriate anticoagulation (OAC) therapy. However, men with CHA2DS2VASc score = 1 and women with CHA2DS2VASc = 2, who are at intermediate TE risk, represent a grey zone where guidelines do not provide a definite OAC indication...

Aims: A 3D transoesophageal echocardiography (3D-TOE) reconstruction tool has recently been introduced. The system automatically configures a geometric model of the aortic root and performs quantitative analysis of these structures. We compared the measurements of the aortic annulus (AA) obtained by semi-automated 3D-TOE quantitative software and manual analysis vs. multislice computed tomography (MSCT) ones. Methods and results: One hundred and seventy-five patients (mean age 81...

AIMS: We aimed to assess the feasibility, efficacy and safety of short-term dual antiplatelet therapy (DAPT) for 6 weeks after left atrial appendage closure (LAAC). METHODS AND RESULTS: Data of the Cardioangiologisches Centrum Bethanien-LAAC registry were analysed. DAPT (aspirin 100mg plus clopidogrel 75mg) was administered until transoesophageal echocardiography (TEE) evaluation 6 weeks after LAAC. In the absence of significant peri-device flow or device-related thrombus (DRT) the medication was decreased to single antiplatelet therapy (SAPT)...

OBJECTIVES: Left ventricular assist device (LVAD) support is an increasingly important and successful therapeutic option for patients with end-stage heart failure. As chronic heart failure progresses, the left and right ventricles adapt by enlarging its volume and patients present for LVAD implantation with varying degrees of dilatation. By quantitatively assessing right ventricular (RV) and left ventricular (LV) volumes using 3D transoesophageal echocardiography and correlating the findings with clinical outcomes, we aim to investigate the prognostic value of LV and RV volumes for early survival after LVAD implantation...

The objective of this investigation was to assess whether between-hospital variation in echocardiography usage for patients with Staphylococcus aureus bacteraemia (SAB) is explained by differences in patients' pre-test probability of endocarditis. This was a retrospective cohort study at three neighbouring hospitals in Australia. Consecutive episodes of SAB were reviewed for the presence of three endocarditis risk factors (community onset, prolonged bacteraemia and the presence of an intracardiac prosthetic device) and the performance and results of all echocardiography studies within 30 days...

The development of an aorto-right ventricular fistula is a rare complication of cardiac surgery. The most common treatment is surgical closure of the fistula, but percutaneous closure of the fistula has become an attractive alternative option. We present a case of successful utilization of live/real time three/four-dimensional transoesophageal echocardiography (3/4DTEE) to select the correct device size for percutaneous closure of an adult patient presenting with an aorto-right ventricular (AO-RV) fistula following aortic valve replacement...
