Weight Loss In Patients With Implanted Defibrillators Predicts Worse Health Outcomes

Even minor weight loss is associated with worse health outcomes among patients implanted with a certain type of defibrillator known as cardiac resynchronization therapy with defibrillator (CRT-D), according to research presented at the American College of Cardiology's 62nd Annual Scientific Session. People with symptoms of heart failure who have an implantable CRT-D device may believe that losing weight will ultimately improve their long-term health outcomes...

Patients with a systemic right ventricle (SRV) are at high risk for development of heart failure early in life. An SRV is encountered in patients with congenitally corrected transposition of the great arteries (CCTGA) or dextro-transposition of the great arteries (DTGA) with previous atrial switch repair (Mustard or Senning procedure). Progressive heart failure is one of the leading cause of mortality in these patients. Therefore, cardiac resynchronization therapy (CRT) has gained increasing momentum for use in this challenging congenital heart disease (CHD) population.

We present a complex case with successful, high ‐density electroanatomic mapping (EAM) guided corrective His bundle pacing (CHBP) following failed CRT upgrade in a patient with PLSVC, congenital heart disease, and pacing‐associated heart failure. CHBP restored physiological conduction in left bundle branch block with complete conduction block leading to clinical improvement and cardiac remodeling. The presented case supports the growing evidence that EAM‐guided CHBP may be considered a feasible alternative to conventional CRT when venous anatomy is not favorable for left ventricular lead implantation.

Conclusions: Left ventricular dyssynchrony analysed by phase analysis of GMP-SPECT has great clinical significance in LVA patient prognostic evaluation. Patients occurred more cardiac events and death with LVMD and BW was the only independent predictor for cardiac events of patients with LV aneurysm. So cardiac resynchronization therapy (CRT) should be considered for LV aneurysm with baseline LVMD and surgical treatment for these LVA patients would be associated with improved long-term survival.

Michel Mirowski and his colleagues gave the field of implantable cardioverter-defibrillators (ICDs) a pretty good start, but what's more impressive is how far the technology has advanced since that first human ICD implant in February 1980. In the past 40 years we've seen ICDs become dramatically smaller, longer lasting, more capable, more personalized, subcutaneous (non-transvenous), and even MRI-firendly. And that's not to mention the advanced data connectivity and monitoring capabilities that the latest technologies offer. So without further ado, let's take a look at the current ICD landscape and the companie...

AbstractHeart failure with reduced ejection fraction (HFrEF) is common in patients with adult congenital heart disease. Many of the most common congenital defects have a high prevalence of HFrEF, including left-sided obstructive lesions (aortic stenosis, coarctation of the aorta, Shone complex), tetralogy of Fallot, Ebstein anomaly, lesions in which there is a systemic right ventricle, and lesions palliated with a Fontan circulation. However, heart failure with preserved ejection fraction (HFpEF) is also prevalent in all these lesions. Comprehensive evaluation includes physical exam, biomarkers, echocardiography and advanc...

, Jacobo-García K, Cossio-Aranda J Abstract Heart failure (HF) is a syndrome characterized basically by a circulatory deficit to cover the metabolic and energetic demands of the body. This condition has a broad spectrum in its clinical presentation, affects the quality of life significantly, impacts the family/social environment, and generates a great demand for health services. The purpose of this research is to report the situational diagnose of patients with HF in Mexico. We evaluated 292 patients, 70.2% were men. Average age was 56.7 ± 14.3 years. Ischemic heart disease is the main etiology (98 p...

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...

This study investigated the association between ICD use and all-cause mortality in a contemporary reduced ejection fraction (HFrEF) cohort with a focus on subgroups. The study population was compiled from patients in the Swedish Heart Failure Registry (SwedeHF) fulfilling ESC criteria for primary prevention ICD use. Propensity score matching was used to account for differences at baseline. In a release principal investigator Dr. Benedikt Schrage of the Karolinska Institute in Stockholm, Sweden said: “Most randomized trials on ICD use for primary prevention of sudden cardiac death in HFrEF enrolled patient...

varese G Abstract BACKGROUND: Most randomized trials on implantable cardioverter-defibrillator (ICD) use for primary prevention of sudden cardiac death in heart failure with reduced ejection fraction (HFrEF) enrolled patients>20 years ago. We investigated the association between ICD use and all-cause mortality in a contemporary HFrEF cohort and examined relevant subgroups. METHODS: Patients from the Swedish HF Registry (SwedeHF) fulfilling the European Society of Cardiology criteria for primary prevention ICD were included. The association between ICD use and 1-year and 5-year all-cause and cardiovascular ...
