Atrial fibrillation is the most common arrhythmia worldwide and is a major risk factor for embolic stroke. In this article, the authors describe the crucial role of two- and three-dimensional transesophageal echocardiography in the pre- and postprocedural assessment and intraprocedural guidance of percutaneous left atrial appendage (LAA) occlusion procedures. Although recent advances have been made in the field of systemic anticoagulation with the novel oral anticoagulants, these medications come with a significant risk for bleeding and are contraindicated in many patients...

Tricuspid regurgitation (TR) is a common entity, most commonly functional in nature due to right-sided dysfunction in the setting of concomitant cardiac disease or pulmonary hypertension. Patients living with TR often experience numerous limitations as a result of right-sided heart failure symptoms, including functional decline, frequent hospitalizations, liver failure, and kidney failure. Furthermore, patients with significant TR demonstrate worse survival, although a cause-and-effect relationship has not been proven...

OBJECTIVES: Meta-analyses from observational and randomized studies have demonstrated benefits of off-pump surgery for hard and surrogate endpoints. In some of them, increased re-revascularization was noted in the off-pump groups, which could impact their long-term survival. Therefore, we analyzed the course of all patients undergoing isolated coronary surgery regarding the major cardiac and cerebrovascular event (MACCE) criteria. METHODS: A prospective register was taken from a high-volume off-pump center recording all anaortic off-pump (ANA), clampless off-pump (PAS-Port) and conventional (CONV) coronary artery bypass operations between July 2009 and June 2015...

A fifth of patients with heart failure suffer from conduction disorders. A prolonged QRS duration on the electrocardiogram is an indicator of cardiac dyssynchrony. Several studies have shown the efficacy of cardiac resynchronisation therapy (CRT) in patients with a wide QRS duration: CRT is associated with reduced morbidity and mortality. An overview of the methods of implantation of CRT devices, the results of this electrical treatment and its limits.

Special attention is required in planning and administering radiation therapy to patients with cardiac implantable electronic devices (CIEDs), such as pacemaker and defibrillator. The range of dose to CIEDs that can induce malfunction is large among CIEDs. Clinically significant defects have been reported at dose as low as 0.15 Gy. Therefore, accurate estimation of dose to CIED and dose reduction are both important even if the dose is expected to be less than the often-used 2-Gy limit. We investigated the use of bolus in in vivo dosimetry for CIEDs...

REVIEW
Christian A Bermudez, D Michael McMullan
Increased experience with extracorporeal life support (ECLS) as a mode of cardiac support has expanded its use to diverse patient populations including patients requiring a bridge to heart transplantation and patients requiring posttransplant support for primary graft dysfunction (PGD). The use of ECLS is associated with acceptable outcomes in well-selected patients. While outcomes with the use of extracorporeal membrane oxygenation (ECMO) as a bridge to heart transplant have been variable, several series have confirmed the safe use of ECLS to stabilize patients prior to left ventricular assist device (LVAD) implantation...

As Japan has one of the most rapidly aging populations in the world, transcatheter aortic valve implantation (TAVI) is likely to be performed in increasing numbers of older people. There is little information on either the efficacy or the safety of TAVI in nonagenarians in Asia.From October 2013 to June 2015, 112 consecutive patients underwent TAVI with Edwards SAPIEN XT valves in our institution. We compared 25 patients aged at least 90 years (mean 91.6 ± 1.7 years) with 87 patients aged under 90 years (mean 82...

AIMS: A relevant number of patients presenting for electrical cardioversion carry a pacemaker (PM) or ICD. Case reports suggest a potential hazard of external cardioversion/defibrillation. The incidence of shock related device complications is unknown. No guidelines or recommendations by international medical societies for a cardioversion protocol of cardiovascular implantable electronic device (CIED) patients exist. We conducted a nationwide survey to gather real-world clinical data on the current clinical approach towards these patients during electrical cardioversion and to estimate the incidence of shock-related complications...

BACKGROUND: Fluid therapy remains a cornerstone of therapy in shock states. However, fluid overloading ultimately results in edema formation which is related to excess morbidity and mortality. Handheld microscopes are now frequently used to study the sublingual microcirculation. As a corollary, these devices measure focal distance, or surface to capillary distance. Physiologically, this could represent a microvascular index of edema formation and could have the potential to guide fluid therapy...

BACKGROUND: Implantable cardioverter defibrillators (ICDs) are lifesaving devices for patients with heart failure (HF) and reduced ejection fraction. However, utilization and determinants of ICD insertion in Asia are poorly defined. We determined the utilization, associations of ICD uptake, patient-perceived barriers to device therapy and, impact of ICDs on mortality in Asian patients with HF. METHODS AND RESULTS: Using the prospective ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, 5276 patients with symptomatic HF and reduced ejection fraction (HFrEF) from 11 Asian regions and across 3 income regions (high: Hong Kong, Japan, Korea, Singapore, and Taiwan; middle: China, Malaysia, and Thailand; and low: India, Indonesia, and Philippines) were studied...

OBJECTIVES: Heart valve replacement with a bioprosthesis is one of the most frequently performed procedures in cardiac surgery and represents a highly effective therapy to relieve diseased heart valves. Nevertheless, as postoperatively elevated transvalvular gradients and prosthesis-patient mismatch are reported as shortcomings of the procedure or of the currently used devices, there is a need for novel bioprostheses with improved haemodynamics. This study presents preclinical haemodynamic results after mitral valve replacement with the novel TRIBIO bioprosthesis (TRIBIO) compared with an established bioprosthesis in a sheep model...

AIMS: Cardiac dysfunction is a severe complication of anthracycline-containing anticancer therapy. The outcome of anthracycline-induced cardiomyopathy (AICM) compared with other non-ischaemic causes of heart failure (HF), such as idiopathic dilated cardiomyopathy (IDCM), is unresolved. The aim of this study was to compare the survival of AICM patients with an IDCM cohort followed at our centre from 1990 to 2016. METHODS AND RESULTS: We included 67 patients (67% female, 50 ± 15 years) with AICM, defined as onset of otherwise unexplained left ventricular ejection fraction (LVEF) ≤50% following anthracycline therapy, and 488 IDCM patients (28% female, 55 ± 12 years)...
