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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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. During the ablation of the left superior pulmonary vein (LSPV), the patient developed severe hypotension and bradycardia. The patient's monitor revealed ST elevation, confirmed by a 12-lead ECG. Immediate coronary angiography revealed the left main coronary spasm, which improved with nitroglycerine administration with resolution of ST elevation and return of the patient's hemodynamics to stability. The patient's left main CAS was induced by cryoablation of LSPV. Literature on atrial fibrillation ablation-induced CAS is scant, but a Japanese study has shown that it occurs more commonly in cryoablation than in radiofrequency, hot balloon, or laser ablation. The study showed LSPV as the most common site of ablation right before the spasms happened. Further studies about this topic are needed to delineate further the risk factors and the precautions that could prevent CAS. In the meantime, prompt recognition and appropriate intervention are critical for a good patient outcome.
