Ambulatory monitoring of heart sounds via an implanted device is superior to auscultation for prediction of heart failure events

Heart failure (HF) is a complicated syndrome, and despite advances in medical and device-based therapies in the last three decades, the 5-year mortality of patients with HF remains around 50%.1 Increasingly, patients with HF are implanted with implantable cardioverter defibrillators or cardiac resynchronization therapy devices that possess the capability of measuring many diagnostic parameters.

ConclusionThis analysis from the European CRT Survey II overall shows good guideline adherence, high implantation success and a low rate of complications in daily practice. There are some regional differences in baseline characteristics, CRT indication, and procedural aspects. The use of remote monitoring in Germany lags behind other European countries.Graphic abstract

AbstractNon-left bundle branch block (non-LBBB) remains an uncertain indication for cardiac resynchronization therapy (CRT). Non-LBBB includes right bundle branch block (RBBB) and non-specific LV conduction delay (NSCD), two different electrocardiogram (ECG) patterns which are not generally considered to be associated with LV conduction delay as judged by the invasive assessment of the Q-LV interval. We evaluated whether a novel ECG interval (QR-max index) correlated with the degree of LV conduction delay regardless of the type of non-LBBB ECG pattern, and could, therefore, predict CRT response. In 173 non-LBBB patients on...

CONCLUSION: In a population of HF patients undergoing CRT, CD was independently associated with mortality and hospitalization for HF.RESUMO INTRODU ÇÃO: A terapia de ressincronização cardíaca (TRC) é uma modalidade terapêutica para pacientes com insuficiência cardíaca (IC). A eficácia desse tratamento para redução de eventos baseia-se em ensaios clínicos em que a população de pacientes com doença de Chagas (DC) é sub-representa da. OBJETIVO: Avaliar o prognóstico após TRC em uma populaç&...

Abstract Permanent His bundle pacing (HBP) activates the ventricles through the normal conduction system and has become a useful technique for patients with a high ventricular pacing rate. Presently described is a case of drug-refractory atrial fibrillation (AF) with a high ventricular rate that was treated with atrioventricular (AV) node ablation and permanent HBP. A 62-year-old woman with persistent AF and a drug-refractory high ventricular response was referred for exercise intolerance and palpitation. She had a history of failed catheter ablation attempts and amiodarone toxicity. Permanent HBP and AV node abla...

AbstractPurpose of ReviewTo introduce the reader to the basics of pressure-volume (PV) analysis, its current role in management of heart failure and valvular disease, and the possibilities for future use.Recent FindingsThe recent introduction of FDA-approved miniaturized conductance catheters that can produce PV loops in the clinical setting has set the stage for the translation of this important research technique into clinical practice. The use of these catheters has shed important insights into the pathophysiology of many common conditions associated with heart failure including heart failure with preserved ejection fra...

Publication date: Available online 20 November 2019Source: Canadian Journal of CardiologyAuthor(s): Ashlay A. Huitema, Karen Harkness, Shiraz Malik, Neville Suskin, Robert S. McKelvieABSTRACTGlobally, there are approximately 26 million people living with heart failure (HF) and 50% of those patients suffer from HF with reduced ejection fraction (HFrEF), costing countries billions of dollars each year. Improvements in treatment of cardiovascular diseases, including advanced HF, have allowed an unprecedented number of patients to survive into old age. Despite these advances, patients with HF deteriorate and often require adva...

Conclusion: Our study showed that vitamin D deficiency has a significant impact in heart failure patients; it is an independent predictor of lack of midterm clinical response and long-term mortality in patients undergoing CRT. Therefore, monitoring vitamin D status of heart failure patients could be of clinical significance. PMID: 31737126 [PubMed - in process]

Authors: Singh A, Karnik R, Shah AN, Chutani S, Kantharia BK Abstract Aims: Response to cardiac resynchronisation therapy (CRT) in patients with heart failure depends on the degree of correction of electromechanical dyssynchrony between the left and right ventricles (LV, RV). It is not known whether chronic programming of interventricular (VV) intervals based on characterisation of myocardial strain at different pacing intervals performed acutely would have better long-term clinical outcomes. We hence aimed to evaluate this relationship between speckle tracking strain patterns and rates at different VV intervals an...
