BACKGROUND: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. METHODS: In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information...

The number of people with heart failure requiring implantation of a cardiac resynchronization device is increasing in Iran. Although this intervention is an effective life-saving treatment, several challenges are associated with patients' lifestyle after insertion. This study identified the challenges and coping mechanisms of Iranians with heart failure living with cardiac resynchronization therapy. A qualitative approach using conventional content analysis was adopted. Seventeen people with heart failure and three nurses were recruited between December 2014 and November 2015 from a teaching hospital and a private clinic in Rasht, Iran...

AIMS: Cardiac resynchronization therapy (CRT) induces reverse cardiac remodelling in heart failure (HF), but many patients receiving CRT remain non-responders. This study assessed the role of amino-terminal-pro-B-type natriuretic peptide (NT-proBNP), mid-regional-pro-atrial natriuretic peptide (MR-proANP), and mid-regional-pro-adrenomedullin (MR-proADM) at the time of device implantation to predict favourable clinical course (CRT response and/or risk of MACE) in HF patients receiving CRT...

BACKGROUND: Left ventricular end-systolic volume (LVESV) changes at 6 months and clinical status are useful for assessing responses to cardiac resynchronization therapy (CRT). Regression of the LVESV following CRT has not been described beyond 6 months. This study aimed to assess the proportion, predictors, and clinical outcomes of responders whose LVESVs had regressed. METHODS: We retrospectively analyzed 104 consecutive CRT patients. A responder was defined as a patient with a relative reduction in the LVESV ≥15% at 6 months after CRT...

In the second part of this 2-part series on pacemakers, we present recent advances in pacemakers and preview future developments. Cardiac resynchronization therapy (CRT) is a potent treatment for heart failure in the setting of ventricular dyssynchrony. Successful CRT using coronary venous pacing depends on appropriate patient selection, lead implantation, and device programming. Despite optimization of these factors, nonresponse to CRT may occur in one-third of patients, which has led to a search for alternative techniques such as multisite pacing, His bundle pacing, and endocardial left ventricular pacing...

PURPOSE OF REVIEW: Heart failure is a significant public health concern around the world. Implantable cardioverter defibrillators with or without cardiac resynchronization therapy (CRT-D) have proven survival benefit. As patients progress to end-stage disease, management shifts to palliative care, and cardiologists are often confronted with how to best manage these devices. RECENT FINDINGS: Studies suggest that up to one-third of patients with an implantable cardioverter defibrillator receive painful shocks in the last 24 h of life...

AIMS: Selection of patients who are viable candidates for cardiac resynchronization therapy (CRT), prediction of the response to CRT as well as an optimal definition of a favorable response, all require further exploration. The purpose of this study was to evaluate the interplay between the prediction of the response to CRT and the definition of a favorable outcome. METHODS: Seventy patients who received CRT were included. All patients met current guideline criteria for CRT...

AIMS: Endocardial left ventricular (LV) pacing for Cardiac Resynchronization Therapy has been proposed as an alternative to conventional LV lead placement via the coronary sinus. In order to assess the relative benefits and risks of this technique, we have performed a meta-analysis of published reports. METHODS AND RESULTS: A systemic search was performed using online databases to identify studies of lead-based endocardial pacing. A random-effects meta-analysis was performed, to assess the rate of complications and clinical response (defined as ≥1 decrease in NYHA class)...

We presented a unique phenomenon of 2:1 cardiac resynchronization therapy pacing due to T wave oversensing. Ultimately, by utilizing a unique feature of integrated bipolar sensing, we succeeded to eliminate the T wave oversensing signals, and restore 1:1 CRTD pacing. Importantly, this feature enabled us to overcome the T wave oversensing issue, without the need to decrease the ventricular sensitivity, which could potentially interfere with ventricular arrhythmia detection and appropriate shock delivery when required...

Although cardiac resynchronization therapy (CRT) has become a well-established treatment option for patients with drug-refractory severe systolic heart failure, there has been some evidence of adverse proarrhythmic events. We report a case of a patient with ischemic cardiomyopathy who underwent CRT with a defibrillator for primary prevention of sudden cardiac death. Two years after the implantation, the patient presented with electrical storm, which was completely terminated by modifying the left ventricular (LV) pacing configuration from true to extended bipolar LV pacing...

PURPOSE: To image late mechanical activation and identify effective left-ventricular (LV) pacing sites for cardiac resynchronization therapy (CRT). There is variability in defining mechanical activation time, with some studies using the time to peak strain (TPS) and some using the time to the onset of circumferential shortening (TOS). We developed improved methods for imaging mechanical activation and evaluated them in heart failure (HF) patients undergoing CRT. MATERIALS AND METHODS: We applied active contours to cine displacement encoding with stimulated echoes (DENSE) strain images to detect TOS...

REVIEW

Cardiac resynchronization therapy (CRT) has had a major favourable impact on the care of patients with symptomatic heart failure, left ventricular ejection fraction<35% and enlarged QRS. Despite this, about 35% of patients who undergo CRT in accordance with current guidelines are "non-responders". Therefore, more accurate selection of CRT candidates would significantly improve patient benefit and decrease costs. In the past decade, some small non-randomized studies have shown that estimation of left ventricular dyssynchrony by echocardiography might be useful to ameliorate the selection of patients for CRT...
