Herein, we present the case of a 49-year-old woman who presented to a peripheral hospital with a 4-day history of progressive shortness of breath. Following a clinical diagnosis of heart failure and slightly elevated cardiac troponins on initial blood work, the patient was referred for same-day diagnostic coronary angiography, which revealed normal coronary arteries but the surprising finding of a fluoroscopic swinging heart due to a massive pericardial effusion. The patient promptly improved after emergent pericardiocentesis. Fluoroscopic clues to the diagnosis of pericardial effusion are reviewed, with accompanying illustrative video and hemodynamic tracings.

Left atrial strain assessed by speckle tracking imaging is related to new-onset atrial fibrillation after coronary artery bypass grafting.
Left atrial (LA) dysfunction was recently proposed as an important factor in the development of postoperative atrial fibrillation (POAF). LA strain analysis by 2-dimensional (2D) speckle tracking imaging is emerging as a new tool to evaluate LA function. We aimed to evaluate the correlation of LA dysfunction assessed by 2D speckle tracking imaging with the occurrence of POAF after coronary artery bypass grafting (CABG). ⋯ Preoperative LA global strain measured by 2D speckle tracking strain analysis is associated with the development of POAF after CABG.

Many developments have occurred since the publication of the widely-used 2009 Canadian Cardiovascular Society (CCS) Dyslipidemia guidelines. Here, we present an updated version of the guidelines, incorporating new recommendations based on recent findings and harmonizing CCS guidelines with those from other Societies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used, per present standards of the CCS. ⋯ This document presents the recommendations and principal conclusions of this process. Along with associated Supplementary Material that can be accessed online, this document will be part of a program of knowledge translation. The goal is to increase the appropriate use of evidence-based cardiovascular disease event risk assessment in the management of dyslipidemia as a fundamental means of reducing global risk in the Canadian population.

The 2012 Canadian Cardiovascular Society Heart Failure (HF) Guidelines Update provides management recommendations for acute and chronic HF. In 2006, the Canadian Cardiovascular Society HF Guidelines committee first published an overview of HF management. ⋯ With this in mind and in response to stakeholder feedback, the Guidelines Committee in 2012 has updated the overview of both acute and chronic heart failure diagnosis and management. The 2012 Update also includes recommendations, values and preferences, and practical tips to assist the medical practitioner manage their patients with HF.
