Impact of atrial fibrillation on improvement of functional mitral regurgitation in cardiac resynchronization therapy
Functional mitral regurgitation (FMR) and atrial fibrillation (AF) are frequent heart failure (HF) complications. Cardiac resynchronization therapy (CRT) can improve FMR; however, little is known about the influence of AF on FMR improvement.
Authors: Abe S, Yoshihisa A, Ichijo Y, Sato Y, Kanno Y, Takiguchi M, Yokokawa T, Misaka T, Sato T, Oikawa M, Kobayashi A, Yamaki T, Kunii H, Takeishi Y Abstract It has been recently recognized that recovery of left ventricular ejection fraction (EF), termed "recovered EF", occurs in a proportion of heart failure patients with reduced EF (HFrEF), and is associated with better prognosis. However, the clinical characteristics of "recovered EF" have not been fully examined.Consecutive 567 patients hospitalized due to HFrEF (EF
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
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...
CONCLUSIONS: Reactive ATP successfully and safely reduced AF burden, and was associated with a lower incidence of HF hospitalization in patients implanted with CRT devices. PMID: 31672258 [PubMed - as supplied by publisher]
In patients with cardiac resynchronization therapy (CRT), atrial fibrillation (AF) is associated with an unfavorable outcome and may cause loss of biventricular pacing (BivP). An effective delivery of BivP of ...
Conclusions. Patients in AF or SR undergoing CRT demonstrated distinct benefits from device implantation and from HIIT as an adjunctive therapeutic strategy. This suggests that both mainstay and adjunctive therapeutics may need to be managed differently in patients in AF and SR. PMID: 31221002 [PubMed - as supplied by publisher]

In conclusion, elderly patients simultaneously presenting problems of cardiac function and arrhythmia are an important challenge for geriatric medicine, and request important efforts to improve their functional profile and prognosis. PMID: 31162487 [PubMed - in process]
Publication date: June 2019Source: JACC: Heart Failure, Volume 7, Issue 6Author(s): Matthew A. Carlisle, Marat Fudim, Adam D. DeVore, Jonathan P. PicciniAbstractHeart failure and atrial fibrillation are 2 common cardiovascular disorders that frequently complicate one another and exert a significant detrimental effect on cardiovascular health and well-being. Both heart failure and atrial fibrillation continue to increase in prevalence as the risk factors underlying each condition become more common. This review encompasses what is currently known about the epidemiology and pathophysiology of these comorbidities along with i...
CONCLUSIONS: The number of CIED implantation increased substantially from 2009 to 2016 in Korea. Also, the patients with CIED have been changed to be older and have more comorbidities. Therefore, the burden of health care cost in patients with CIED would be expected to increase in the future. PMID: 31074230 [PubMed - as supplied by publisher]
