The Evolving Role of Electrocardiography in Cardiac Resynchronization Therapy.

Purpose Of Review: This study aims to summarize the literature on the role of electrocardiography (ECG) in (i) patient selection for cardiac resynchronization therapy (CRT), (ii) predicting clinical response after CRT system is implanted, and (iii) optimizing CRT programming.

Recent Findings: Progress has been made in interpreting ECG beyond QRS duration and left bundle branch (LBBB) morphology to select patients for CRT. We now understand a higher chance of response to CRT in patients with atypical right bundle branch block and lower response rates in subgroups with atypical LBBB.

Retrospective review of Arctic Front Advance Cryoballoon Ablation: a multicenter examination of second-generation cryoballoon (RADICOOL trial).

Background: Pulmonary vein isolation (PVI) via catheter ablation is an approved therapy for patients with drug-refractory and symptomatic atrial fibrillation (AF). Furthermore, cryoballoon is now considered to be as effective as focal radiofrequency catheter ablation. This study examines the second-generation cryoballoon performance in a US multicenter review of real-world practices.

Native Valve Endocarditis due to Ralstonia pickettii: A Case Report and Literature Review.

Ralstonia pickettii is a rare pathogen and even more rare in healthy individuals. Here we report a case of R. pickettii bacteremia leading to aortic valve abscess and complete heart block.

Regional pericarditis status post cardiac ablation: a case report.

Context: Regional pericarditis is elusive and difficult to diagnosis. Healthcare providers should be familiar with post-cardiac ablation complications as this procedure is now widespread and frequently performed. The management of regional pericarditis differs greatly from that of acute myocardial infarction.

Biventricular takotsubo cardiomyopathy: case study and review of literature.

Biventricular takotsubo cardiomyopathy is associated with more hemodynamic instability than is isolated left ventricular takotsubo cardiomyopathy; medical management is more invasive and the course of hospitalization is longer. In March 2011, a 62-year-old woman presented at our emergency department with abdominal pain, nausea, and vomiting. On hospital day 2, she experienced chest pain.
