The usefulness of QRS Index for prediction of echocardiographic response in cardiac resynchronization therapy: a multicenter study.

Background: The association between QRS narrowing and response to cardiac resynchronization therapy (CRT) has been investigated by several studies, but their findings remain inconclusive. Aim of our study was to explore the relationship between QRS Index and echocardiographic response to CRT.

Methods: This multicenter, retrospective analysis included 326 consecutive patients (mean age was 70.

Electrocardiographic predictors of echocardiographic response in cardiac resynchronization therapy: Update of an old story.

Background: A better selection of patients with left bundle branch block (LBBB) might increase the response to cardiac resynchronization therapy (CRT). The aim of the study was to investigate the association between the Strauss criteria, absence of S wave in V-V the Selvester score and response to CRT.

Methods And Results: The retrospective analysis included all consecutive patients having undergone implantation of biventricular defibrillators in primary prevention between 2018 and 2020.

Team working in the modern medicine: The paradigm of electrophysiology.

In modern Medicine, team working has become crucial to guarantee favorable outcomes in most therapeutical procedures. Electrophysiology (EP) represents an exemplary paradigm of it. Herein, the role of the EP staff members and the importance of cooperation before, during and after the procedure is highlighted.

Mexiletine for ventricular arrhythmias in patients with chronic coronary syndrome: a cohort study.

Background: The pharmacological therapy of ventricular arrhythmias in patients with unsuccessful or not feasible catheter ablation and contraindication or inefficacy to amiodarone and beta-blockers, is controversial. The present study investigated the effectiveness and tolerability of mexiletine in patients with recurrent ventricular arrhythmias and ischaemic heart disease, when the conventional antiarrhythmic therapy failed.

Methods: We enrolled all consecutive patients with unsuccessful/not feasible catheter ablation and ineffective/contraindicated amiodarone or beta-blockers, which started the mexiletine treatment for refractory ventricular tachycardia (VT) or ventricular fibrillation (VF) between January 2010 and January 2020.

Giant Negative T-Waves as Cardiac Memory Phenomenon Following Ablation of Right-Sided Posteroseptal Accessory Pathway.

We present a paradigmatic example of "cardiac memory," characterized by deep, giant, and negative T-waves in the inferior leads, after a successful ablation of a right-sided posteroseptal accessory pathway.

The radiofrequency interference on CRT-D functioning during AV node ablation: An educational case.

We have described some unusual findings of radiofrequency interference with ICD functioning during AV nodal ablation, guiding the reader to the possible explanation of the phenomena.

[Managing cardiac patients post-COVID-19 pandemic: a proposal by the ANMCO Veneto Region].

The COVID-19 post-lockdown period and the subsequent progressive withdrawal of the quarantine measures are currently allowing the gradual resumption of the ordinary clinical activities, which have been suppressed during the COVID-19 pandemic. In this phase, it is crucial to minimize the risk of infection to limit COVID-19-related morbidity and mortality and the number of new cases. Indeed, COVID-19 manifestations may be equivocal, including asymptomatic or mildly symptomatic patients.

An unusual case of AV block.

Nerium oleander is an evergreen small tree, very used in some countries such as India and in Sri Lanka as a self-medication method. We report a case of a 55 year-old man with intermittent, advanced AV block secondary to oleander intoxication.

Management of a patient with heart failure by sacubitril/valsartan: improvement of functional capacity.

The main objectives of the treatment of heart failure (HF) are to improve patient clinical status, functional capacity and quality of life, as well as reducing re-hospitalization rate and mortality. A new compound, consisting of an angiotensin-receptor blocker (ARB) (valsartan) and a neprilysin (NEP) inhibitor (sacubitril), belonging to the newly established class of angiotensin receptor-neprilysin inhibitors (ARNIs) showed marked efficacy, without any relevant safety issue, in the treatment of patients with HF. We report a case of a 48 year old male with HF with reduced ejection fraction (HFrEF) due to hypertensive cardiomyopathy (New York Heart Association [NYHA] class III).

ICD and neuromodulation devices: is peaceful coexistence possible?

Aim: The aim of this study was to investigate the potential cross-talk between implantable cardioverter defibrillator device (ICD) and implantable neuromodulation device (IND) during the implantation procedure and the ventricular fibrillation induction test and in daily life.

Methods: We present two cases of patients with an IND who underwent ICD implantation and one case of a patient implanted with a biventricular ICD who received an IND 6 months later. Two of these patients had a spinal cord stimulator (SCS), while the other had a sacral neuromodulator.

Physiopathologic correlates of intrathoracic impedance in chronic heart failure patients.

Background: Increased plasma levels of amino-terminal fraction of brain natriuretic peptide (NT-proBNP) and alterations of diastolic filling as described by Doppler transmitral flow pattern are well-known markers of decompensated heart failure (HF). Recently, some implantable defibrillators have allowed monitoring of intrathoracic impedance, which is related to lung water content, potentially indicating HF deterioration. The aim of this study was to assess the correlation between intrathoracic impedance and NT-proBNP and echo-Doppler transmitral flow indexes.

An echocardiographic survey of primary school children for bicuspid aortic valve.

Primary school students (817 apparently healthy 10-year olds) were screened by transthoracic 2-dimensional echocardiography to assess for the prevalence of bicuspid aortic valve. Bicuspid aortic valve was found in 0.5% of cases, with a higher prevalence in males than females (0.
