Controversies related to renal artery denervation and devices.

Purpose Of Review: This review article discusses the controversies, strengths, and limitations of the current literature on renal artery denervation in the management of resistant hypertension, as well as the future directions of this intervention.

Recent Findings: There have been conflicting data from the different randomized control trials assessing the efficacy of renal artery denervation in the management of resistant hypertension.

Summary: Renal artery denervation is achieved by ablating the sympathetic nerves surrounding the renal arteries using endovascular ultrasound, radiofrequency, or alcohol.

Sudden Cardiac Death: An Update on Commotio Cordis.

Sudden cardiac death (SCD) is one of the leading causes of cardiovascular mortality, and it is caused by a diverse array of conditions. Among these is commotio cordis, a relatively infrequent but still significant cause, often seen in young athletes involved in competitive or recreational sports. It is known to be caused by blunt trauma to the chest wall resulting in life-threatening arrhythmia (typically ventricular fibrillation).
