Giving the Cold Shoulder to Drug Therapy for Atrial Fibrillation
In two randomized trials published simultaneously, cryoballoon ablation proved superior to drug therapy for prevention of arrhythmia recurrence in patients with paroxysmal atrial fibrillation.

Why Does This WCT Change Its Shape?
Imagine there was no history for the ECG shown in the figure. How would one interpret this tracing?

Left Ventricular Size, Function Predictors of Outcomes in Chronic Aortic Regurgitation
In a large cohort of asymptomatic patients with hemodynamically significant chronic aortic regurgitation, volumetric left ventricular size and function measurements were equally discriminant in identifying patients at higher risk for mortality vs. traditional linear measurements.

Rhythm vs. Rate Control for Atrial Fibrillation Patients: The Controversy Continues
Early use of rhythm control in patients with atrial fibrillation and high cardiovascular risk appears to improve cardiovascular outcomes compared to usual care.
-
Another Affirmation for Rhythm Control in Atrial Fibrillation
A rhythm control strategy implemented less than one year after atrial fibrillation diagnosis was associated with significant reduction in adverse cardiovascular outcomes when compared to usual care.

What Is the Cause of This Regular WCT?
The ECG in the figure was obtained from an older woman who presented with hypotension. What is the rhythm?

The Tactics and Tools to Manage Pediatric Heart Failure
Fortunately, pediatric heart failure is a rare occurrence, but early diagnosis, aggressive management, and timely transfer to a facility capable of advanced cardiac support are essential to optimize the outcome of each child. The authors review the early recognition of a child in heart failure and also discuss an approach to troubleshooting and recognizing complications associated with a ventricular assist device.

How Can This Patient Be Stable?
The ECG in the figure was obtained from a young adult who presented to the emergency department with palpitations, but who otherwise was hemodynamically stable. What is the diagnosis?

A Review of Atrial Fibrillation and Current Therapeutic Strategies: Part 2
This two-part series presents a review of the current evidence on atrial fibrillation (AF). The first part included the definition of AF, its classification, risk factors, comorbidities, evaluation, and acute management of newly diagnosed patients. The second part focuses on long-term management, including risk factor modification, rate and rhythm control measures, stroke risk stratification, and anticoagulation management.

Vitamin C for Postoperative Atrial Fibrillation Risk
The authors of a systematic review of 13 studies found convincing evidence that vitamin C supplementation, beginning before cardiac surgery and continuing for a few days postoperatively, can decrease the risk of atrial fibrillation.
