Multicenter Study Clinical Trial
Culprit Vessel-Only vs. Staged Multivessel Percutaneous Coronary Intervention Strategies in Patients With Multivessel Coronary Artery Disease Undergoing Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction.
We assessed the current status of treatment strategy in ST-segment elevation myocardial infarction (STEMI) with multivessel disease (MVD) in real world practice, focusing on the benefit of staged percutaneous coronary intervention (PCI). ⋯ The staged PCI strategy for angiographically significant non-culprit lesions was associated with lower 5-year mortality compared with the culprit-only PCI strategy in STEMI patients with MVD who underwent primary PCI.

Clinical Trial
Coagulation-Fibrinolysis System and Postoperative Outcomes of Patients With Chronic Thromboembolic Pulmonary Hypertension.
The postoperative changes in the coagulation-fibrinolysis system and the association between the system and postoperative course of patients with chronic thromboembolic pulmonary hypertension (CTEPH) who have undergone pulmonary endarterectomy (PEA) remain unclear. ⋯ Preoperatively high fibrinogen and low plasminogen values in patients with CTEPH are associated with poor long-term postoperative outcome. PEA benefited not only the pulmonary hemodynamics but also the coagulation-fibrinolysis system of patients.

Catheter ablation of atrial fibrillation (AF) has evolved over the past 20 years from being a novel, unproven procedure to a commonly performed procedure. Triggers are important for the initiation of AF and a suitable substrate is important for perpetuation of AF. Remodeling, including electrical and structural remodeling, is common in patients with persistent AF. ⋯ Rotor ablation is controversial. A combined approach using CFAE, similarity and phase mappings with rotor identification may be helpful in searching for AF sources and subsequent substrate ablation. Nevertheless, more prospective randomized studies are required to validate efficacy and safety.
