Article Synopsis
- Radiofrequency catheter ablation is a common treatment for a heart condition called atrial flutter, with cryoablation being another option that uses cold temperatures.
- A 65-year-old man, who didn't respond to medicine for his heart issues, had a cryoablation procedure, during which doctors saw two episodes of ST-elevation, a sign of heart trouble.
- The first episode was fixed by stopping the freezing process, while the second was due to a spasm in the artery and was treated with medicine. This case shows the importance of special imaging technology (ICE) to keep procedures safe.

Background: Idiopathic epicardial premature ventricular contractions (PVCs) originating from the left ventricular summit are difficult to eliminate.
Objective: The purpose of this study was to describe the feasibility and procedural safety of monopolar biphasic focal pulsed field ablation (F-PFA) from within the great cardiac vein (GCV) for treatment of idiopathic epicardial PVCs.
Methods: In 4 pigs, F-PFA (Centauri, CardioFocus) was applied from within the GCV followed by macroscopic gross analysis.

Background: Endothelial dysfunction (ED) suspicion will allow to prevent accelerated atherosclerosis and premature death.
Objective: To establish the usefulness of thermography for endothelial function screening in adults with cardiovascular risk factors.
Material And Methods: Cross-sectional, analytical diagnostic test.

Background: Given the limited access to invasive vasospastic reactivity testing in Western Countries, there is a need to further develop alternative non-invasive diagnostic methods for vasospastic angina (VSA). Hyperventilation testing (HVT) is defined as a class IIa recommendation to diagnose VSA by the Japanese Society of Cardiology.
Methods: In this systematic review and meta-analysis reported according to the PRISMA statement, we review the mechanisms, methods, modalities and diagnostic accuracy of non-invasive HVT for the diagnostic of VSA.
