Impact of Prereperfusion Left Ventricle Unloading on ST-Segment Elevation Myocardial Infarction According to the Onset-to-Unloading Time.

It is unclear whether the impact of prereperfusion unloading on improving survival is sustained throughout all periods from the onset in patients with ST-segment elevation myocardial infarction. This study is a post hoc analysis of the J-PVAD registry. In all patients registered in J-PVAD between February 2020 and December 2021, patients with ST-segment elevation myocardial infarction complicated with cardiogenic shock and treated with Impella support alone were selected.

A case of pulmonary vein reconnection after long-term success of pulmonary vein isolation for atrial fibrillation.

We describe a case where right superior pulmonary vein was not reconnected at the beginning of the third radiofrequency catheter ablation (RFCA) for atrial fibrillation but was reconnected at the beginning of the fourth RFCA. This is a case of pulmonary vein reconnection in the chronic phase after successful pulmonary vein isolation.

Predictors of late recurrence after second catheter ablation for persistent atrial fibrillation.

Background: Little has been reported on the predictors of late recurrence (LR) after second radiofrequency catheter ablation (RFCA) for persistent atrial fibrillation (AF).

Objective: This study aimed to identify the predictors of LR after second RFCA in patients with persistent AF.

Methods: We retrospectively analyzed 123 patients who underwent a second RFCA because of LR after the initial RFCA for persistent AF.

Impact of combining ablation index-guided and very high-power short-duration ablation at posterior wall adjacent to esophagus during perioperative period on procedural factors.

Introduction: The impact of combining ablation index (AI)-guided and very high-power short-duration (vHPSD) ablation on procedural factors at the posterior wall near the esophagus is unclear.

Methods: Atrial fibrillation patients who underwent initial ablation using three-dimensional mapping were enrolled. Patients were classified into two groups: those who underwent only AI-guided pulmonary vein isolation (PVI) (AI group) and those who underwent vHPSD ablation at the posterior wall adjacent to the esophagus in addition to AI-guided PVI (AI + vHPSD group).
