Safety and efficacy of orthodromic snare technique in left ventricular lead delivery in cardiac resynchronization implantation.

Background: Cardiac resynchronization therapy (CRT) improves ventricular function, but a positive response to CRT is often limited due to left ventricular (LV) lead placement in a suboptimal position. Complex coronary venous anatomy can hinder the placement of an LV lead in the target vessel, leading to poor CRT response.

Objective: To report experience with snare-assisted LV lead delivery in CRT and compare outcomes with the conventional LV lead delivery.

Anatomical considerations and clinical interpretation of the 12-lead ECG in the prone position: a prospective multicentre study.

Aims: The aim of this study is to provide guidance for the clinical interpretation of electrocardiograms (ECGs) in prone position and to establish the electroanatomic explanations for the possible differences to supine position ECGs that may be observed. Additionally, to determine if prone back ECG can be used as an alternative to standard ECG in patients who may benefit from prone position.

Methods And Results: The ECG in supine (standard ECG), prone back (precordial leads placed on the patient's back), and prone anterior position (precordial leads placed in the standard position with the subjects in prone position) were prospectively examined on 85 subjects.

Electrocardiographic Features of Patients with COVID-19: An Updated Review.

Numerous systemic manifestations, including cardiac involvement in the form of myocardial infarction, myocarditis, and electrocardiographic changes, have been associated with COVID-19..In this review, the authors describe the electrocardiographic features that have been reported to date in patients affected by this disease and their possible underlying mechanisms.

Tumescent local anesthesia versus general anesthesia for subcutaneous implantable cardioverter-defibrillator implantation.

Background: Subcutaneous implantable cardioverter-defibrillator (S-ICD) is an effective alternative to transvenous implantable cardioverter-defibrillator. General anesthesia (GA) is considered the standard sedation approach because of the pain caused by the manipulation of subcutaneous tissue with S-ICD implantation. However, GA carries several limitations, including additional risk of adverse events, prolonged in-room times, and increased costs.

Fetal Supraventricular Tachycardia: What the Adult Cardiologist Needs to Know.

Fetal supraventricular tachycardia management is challenging, with consequences for both the fetus and the mother. If left untreated, fetal hydrops may ensue, at which point delivery and treatment of the arrhythmia is preferred. However, if the fetus is not at term nor near-term, significant doses of antiarrhythmics may be needed to achieve adequate transplacental bioavailability.

Methodology of Typical Accessory Pathway Catheter Ablation.

Accessory pathways are abnormal electrical conductions between the atrial and ventricular myocardium, bypassing the atrioventricular node and as such are an important substrate for arrhythmias. Ablation is a curative treatment and should always be offered to symptomatic patients and asymptomatic patients with high risk professions. Adequate knowledge and understanding of different mapping and ablation techniques is pivotal to achieve successful outcomes.

Impact of Routine Counseling on Breastfeeding Status in Hospitalized Infants Below 6 Months: Observation From a Large Diarrheal Disease Hospital in Bangladesh.

. Breastfeeding counseling (BFC) plays a crucial role in improving infant and young child feeding practices. To evaluate the impact of activities of BFC unit (BFCU) on breastfeeding practices of infants who were hospitalized for diarrheal illness through their regular counseling, assistance and support, and motivation.
