The Thebesian valve and coronary sinus in cardiac magnetic resonance.
There is no complex research exploring usefulness of cardiac magnetic resonance in the evaluation of the coronary sinus including Thebesian valve, which can be useful before selected electrophysiology procedures. ⋯ In most of the cases, it is possible to visualize and measure the coronary sinus using cardiac magnetic resonance with SSFP sequence. In selected cases, it is necessary to perform additional dedicated short sequences. Thebesian valve was visualized in almost 50% of patients.

Safety and efficacy outcomes of protamine administration for heparin reversal following cryoballoon-based pulmonary vein isolation.
Anticoagulation with heparin is required during catheter ablation of atrial fibrillation (AF) to reduce systemic thromboembolism. In this study, we aim to compare safety and efficacy outcomes between patients who receive protamine administration for reversal of heparin and those who do not, following cryoballoon-based pulmonary vein isolation (PVI) for AF. ⋯ To the best of our knowledge, this is one of the largest series showing that protamine administration for heparin reversal in patients undergoing cryoballoon-based PVI allows quicker sheath removal and minimizes the risk of potential vascular complications without causing an increase in thrombotic events.
