Left Main Coronary Artery Spasm During Cryoballoon Ablation for Atrial Fibrillation: A Case Report and Literature Review.

Although phrenic nerve and esophageal injury are commonly known risks associated with cryoablation, there is limited literature regarding coronary artery spasm (CAS), a serious and potentially fatal complication of cryoablation. We report the case of a 68-year-old Caucasian female who developed a left main CAS with a significant hemodynamic compromise during cryoablation. The patient, with a history of hyperlipidemia, hypertension, and symptomatic persistent atrial fibrillation, was admitted for elective catheter ablation for atrial fibrillation.

Lessons for Physicians from Flint's Water Crisis.

Physicians form a vital front in recognizing unusual clinical presentations that could herald a health threat. In the Flint water crisis, physicians can be credited with playing critical roles in both uncovering the crisis and providing leadership when government failed to respond effectively. Yet most physicians in Flint were not formally trained in advocacy or leadership and might have recognized the health implications of the crisis more quickly had they received formal environmental health training.
