Feasibility and potential benefit of pre-procedural CMR imaging in patients with ischaemic cardiomyopathy undergoing cardiac resynchronisation therapy.

CONCLUSIONS: The degree of reverse remodelling was larger in patients with leads situated in a scar-free LCR. In patients with leads situated within scar there was a neutral effect on reverse remodelling, which can be caused both by higher scar burden or lead position. These findings demonstrate the feasibility of a CMR work-up and potential benefit in ICM patients undergoing CRT. PMID: 31953775 [PubMed - as supplied by publisher]

Conclusions: This retrospective registry-based study provides a picture of CIED first implants in HCM patients in a Swedish tertiary university hospital. ICDs were the most commonly implanted devices, covering 59% of CIED implants. HCM patients receiving a pacemaker or an ICD had different epidemiological and clinical profiles.

This study aimed to investigate eligibility, titration, and tolerability for Sac/Val in a real ‐world clinical setting.Methods and resultsThis retrospective cohort study consists of two parts. In Part 1 (eligibility study), all patients discharged from Sahlgrenska University Hospital due to HF were consecutively included during 1 year. Data from the patients' medical records were collected. Patients were adjudicated to be eligible based on European Society of Cardiology (ESC) criteria for angiotensin receptor neprilysin inhibitor (ARNI) with the exception of N ‐terminal (NT)‐proBNP levels. Patients who received

AbstractAimsEchocardiographic response after cardiac resynchronization therapy (CRT) is often lesser in ischaemic cardiomyopathy (ICM) than non ‐ischaemic dilated cardiomyopathy (NIDCM) patients. We assessed the association of heart failure aetiology on the amount of reverse remodelling and outcome of CRT.Methods and resultsNine hundred twenty ‐eight CRT patients were retrospectively included. Reverse remodelling and endpoint occurrence (all‐cause mortality, heart transplantation, or left ventricular assist device implantation) was assessed. Two response definitions [≥15% reduction left ventricular end systolic vo...

AbstractIndications of cardiac resynchronization therapy (CRT) do not include exercise ‐induced left bundle branch block, but functional impairment could be improved with CRT in such cases. A 57‐year‐old woman with idiopathic dilated cardiomyopathy (ejection fraction 23%) presented with New York Heart Association Class IV and recurrent hospitalizations. During heart transplant e valuation, a new onset of intermittent left bundle branch block was observed on the cardiopulmonary exercise test. CRT was implanted, and 97% resynchronization rate was achieved. In 12 month follow‐up, both clinical and prognostic exercise ...

AbstractIntroductionWe investigated whether pacing ‐induced electrical dyssynchrony at the time of cardiac resynchronization therapy (CRT) device implantation was associated with chronic CRT response.Methods and resultsWe included a total of 69 consecutive heart failure patients who received a CRT device. Left (LVp ‐RVs) and right (RVp‐LVs) pacing‐induced interlead delays were measured intra‐operatively and used to determine if there was paced left ventricular (LV) dyssynchrony (PLVD), defined as present when LVp‐RVs is larger than RVp‐LVs. CRT response was defined as a reduction in LV end‐systol ic volume ...

Why VTs have wide QRS complex? Brief answer: VT  usually presents with wide QRS tachycardia because it originates in ventricular myocardium, travels muscle to muscle instead of the normal conduction system. However, VTs need not be wide always, if it captures the conduction system early and more proximally it can be as narrow as SVT. Further reading: Only for cardiology fellows  Two empirical statements are made here. (The scientific chances of both being reasonably correct are fair) 80 % of wide QRS tachycardia by default is VT. That means 20 % of wide QRS is not VT. We all accept that. 80 % of narrow QRS tachy...

The residual risk of ventricular arrhythmia (VA) after cardiac resynchronization therapy (CRT) implantation in patients with non-ischemic cardiomyopathy (NICM) remains difficult to evaluate. The impact of left ventricular (LV) wall thickness (WT) measured using computed tomography (CT) on the occurrence of VA after CRT implantation has never been investigated. In this pilot study, we examined the association of LVWT and the occurrence of VA in NICM patients receiving CRT. Thirty three patients with NICM scheduled for CRT underwent pre-procedural CT.
