Chronic heart failure (HF) is one of the main causes of mortality and morbidity worldwide and represents a growing challenge in interventional cardiology. Its prevalence is recently increasing due to the improvements in cardiac care with subsequent significant reduction in the HF acute mortality. HF may occur with either a reduced left ventricular ejection fraction (LVEF) (LVEF<40%, HFrEF) or a preserved EF (typically LVEF≥50%, HFpEF) indicative of diastolic dysfunction. Despite recent advances in drug therapies as well as in nonpharmacological strategies, including defibrillators, cardiac resynchronization therapy, LV assist devices (LVAD), mortality in HF remains high...

INTRODUCTION: Chagas disease represents an important health problem with socioeconomic impacts in many Latin-American countries. It is estimated that 20% to 30% of the people infected by Trypanosoma cruzi will develop chronic Chagas cardiomyopathy (CCC), which is generally accompanied by heart failure (HF). Cardiac resynchronization therapy (CRT) may be indicated for patients with HF and electromechanical dysfunctions. OBJECTIVE: The primary endpoint of this study was to analyze the response to CRT in patients with CCC, while the secondary endpoint was to estimate the survival rates of CRT responder patients...

INTRODUCTION AND OBJECTIVES: Cardiac resynchronization therapy (CRT) is beneficial for selected heart failure (HF) patients, although nonresponse to therapy is still prevalent. We investigated a set of novel biomarkers associated with various pathophysiological pathways of HF. Our purpose was to assess their ability to predict clinical outcomes after CRT. METHODS: We studied 136 chronic HF patients undergoing CRT. We measured the plasma levels of fractalkine, pentraxin-3, hepatocyte growth factor (HGF), carbohydrate antigen-125, and matrix metalloproteinase-9 before and 6 months after CRT...

CRT is a therapeutic option for patients with heart failure, sinus rhythm, prolonged QRS complex duration and reduced ejection fraction. We present a case of 71-year-old woman with dilated cardiomyopathy, NYHA functional class III and AF. We implanted CRT combined with direct His-bundle pacing. The indication for such a therapy was a left bundle branch block with a QRS complex of 178ms and a left ventricular EF of 15%, left ventricular end-diastolic diameter (LVEDD) of 75mm. After 8months of follow-up the LVEDD was 60mm with EF 35-40%...

Aims: Cardiac resynchronization therapy (CRT) is an established procedure for patients with heart failure. However, trials evaluating its efficacy did not include patients with chronic Chagas cardiomyopathy (CCC). We aimed to assess the role of CRT in a cohort of patients with CCC. Methods and results: This retrospective study compared the outcomes of CCC patients who underwent CRT with those of dilated (DCM) and ischaemic cardiomyopathies (ICM). The primary endpoint was all-cause mortality and the secondary endpoints were the rate of non-advanced New York Heart Association (NYHA) class 12 months after CRT and echocardiographic changes evaluated at least 6 months after CRT...

BACKGROUND: Since only 60-70% of select patients with chronic heart failure (CHF) are responders in cardiac resynchronization therapy (CRT), this study aimed to investigate whether serum cystatin C (Cys C) can be used to evaluate the effectiveness of CRT in patients with CHF. METHODS: Seventy-six patients implanted with CRT were retrospectively enrolled. The concentration of serum Cys C was detected and echocardiography was performed before and after 15 days, 1 month, and 6 months of CRT...

PURPOSE: Renal dysfunction is often associated with chronic heart failure, leading to increased morbi-mortality. However, data regarding these patients after cardiac resynchronization therapy (CRT) is sparse. We sought to evaluate response and long-term mortality in patients with heart failure and renal dysfunction and assess renal improvement after CRT. METHODS: We analyzed 178 consecutive patients who underwent successful CRT device implantation (age 64 ± 11 years; 69% male; 92% in New York Heart Association (NYHA) functional class ≥ III; 34% with ischemic cardiomyopathy)...

PURPOSE OF REVIEW: We review the trials that have demonstrated potentially harmful effects from right ventricular (RV) apical pacing as well as reviewing the evidence of alternative RV pacing sites and cardiac resynchronization therapy (CRT) for patients who have heart failure and atrioventricular (AV) block. RECENT FINDINGS: The role of CRT in patients with AV block and impaired left ventricular function remains an important consideration. The BLOCK HF trial demonstrated better outcomes with CRT pacing over RV pacing in patients with left ventricular systolic dysfunction (LVSD) and AV block who were expected to have a high RV pacing burden, but failed to demonstrate a mortality benefit...

The prevalence of chronic heart failure (CHF) is steadily increasing. Both sexes are affected, with significant differences in etiology, epidemiology and clinical presentation, prognosis, comorbidities, and response to treatment. Women tend to develop CHF at a more advanced age, present more often with HF with preserved ejection fraction, are more symptomatic, and have a worse quality of life than men, but also a better prognosis. In women, CHF has more frequently a non-ischemic etiology, and arterial hypertension and diabetes mellitus are leading comorbidities...

Cardiac resynchronization therapy (CRT) is a therapeutic option of increasing importance for chronic heart failure (CHF) and criteria for implantation now concern a large amount of patient populations. As a consequence, subjects with ongoing CRT (or immediately after CRT implantation) are more often referred to Cardiac Rehabilitation (CR) programmes, and it has been recently estimated that about one third of CHF patients attending CR in Italy currently have this kind of device. The presence of CRT represents a modulating factor for exercise prescription and monitoring, since CRT patients may be considered per se as a target group for CR...

BACKGROUND: Infection is a major complication of pacemaker (PM) and implantable cardioverter-defibrillator (ICD) implantation. The present study sought to analyse the incidence rate of device infections, to investigate possible relationships between first implantations/repeated procedures and infection rates, and to identify some main risk factors associated with infection of cardiac implantable electronic devices (CIED). METHODS: In a single center retrospective observational study, records of 3899 consecutive patients having undergone PM and ICD implantation, cardiac resynchronization therapy (CRT) or revision (device/lead replacements or upgrades) and between 2002 and 2012 were obtained...

BACKGROUND: According to current European Society of Cardiology guidelines for the diagnosis and treatment of heart failure (HF), cardiac resynchronisation therapy (CRT) is indicated in patients suffering from HF with reduced ejection fraction (EF) with significantly widened QRS complexes. The presence of vital myocardium proven by dobutamine stress echocardiography (DSE) is considered as a good prognostic factor for responsiveness to this treatment. Chronotropic incompetence is, on the other hand, a known factor of unfavourable outcome in HF...

It is now well recognized that heart failure (HF) patients with left bundle branch block (LBBB) derive substantial clinical benefits from cardiac resynchronization therapy (CRT), and LBBB has become one of the important predictors for CRT response. The conventional tachypacing-induced HF model has several major limitations, including absence of stable LBBB and rapid reversal of left ventricular (LV) dysfunction after cessation of pacing. Hence, it is essential to establish an optimal model of chronic HF with isolated LBBB for studying CRT benefits...

BACKGROUND: Clinical studies demonstrate that up to 40% of patients do not respond to cardiac resynchronization therapy (CRT), thus, appropriate patient selection is critical to the success of CRT in heart failure. OBJECTIVE: Evaluation of mortality predictors and response to CRT in the Brazilian scenario. METHODS: Retrospective cohort study including patients submitted to CRT in a tertiary hospital in southern Brazil from 2008 to 2014. Survival was assessed through a database of the State Department of Health (RS)...

BACKGROUND: Heart failure is common in patients with permanent pacemakers. Right ventricular (RV) pacing may worsen cardiac function, while the nonresponder rate of cardiac resynchronization therapy (CRT) for heart failure treatment remains 25%-30%. OBJECTIVE: The purpose of this study was to assess clinical outcomes of upgrading to permanent His bundle pacing (pHBP) in patients with heart failure who underwent device upgrade from right ventricular pacing or CRT nonresponse...
