Multicenter Study Comparative Study Observational StudyTranscatheter Aortic Valve Implantation Compared With Surgical Aortic Valve Replacement in Low-Risk Patients.
The proven efficacy of transcatheter aortic valve implantation (TAVI) in high-risk patients is leading to the expansion of its indications toward lower-risk patients. However, this shift is not supported by meaningful evidence of its benefit over surgical aortic valve replacement (SAVR). This analysis aims to describe outcomes of TAVI versus SAVR in low-risk patients. ⋯ In patients with low operative risk, significantly better 3-year survival and freedom from major adverse cardiac and cerebrovascular events were observed after SAVR compared with TAVI. Further studies on new-generation valve prostheses are necessary before expanding indications of TAVI toward lower-risk patients.

Randomized Controlled Trial Multicenter StudyEarly Stent Thrombosis and Mortality After Primary Percutaneous Coronary Intervention in ST-Segment-Elevation Myocardial Infarction: A Patient-Level Analysis of 2 Randomized Trials.
Early stent thrombosis (ST) within 30 days after primary percutaneous coronary intervention in ST-segment-elevation myocardial infarction is a serious event. We sought to determine the predictors of and risk of mortality after early ST according to procedural antithrombotic therapy. ⋯ URL: http://www.clinicaltrials.gov.

Comparative StudyComparison of Long-Term Outcomes of Endovascular Management for Membranous and Segmental Inferior Vena Cava Obstruction in Patients With Primary Budd-Chiari Syndrome.
Endovascular management is important for the treatment of primary Budd-Chiari syndrome, which is caused by inferior vena cava (IVC) obstruction. The aims of this study were to compare long-term outcomes of endovascular management for primary Budd-Chiari syndrome patients with membranous obstruction of IVC (MOVC) and segmental obstruction of IVC (SOVC) and explore the optimal endovascular strategy for these conditions. ⋯ The long-term treatment outcome of endovascular management was better for primary Budd-Chiari syndrome patients with MOVC than for those with SOVC. Balloon dilation alone could be the optimal treatment for patients with MOVC. However, stent placement should be more strongly recommended for patients with SOVC.

Comparison of Immediate With Delayed Stenting Using the Minimalist Immediate Mechanical Intervention Approach in Acute ST-Segment-Elevation Myocardial Infarction: The MIMI Study.
Delayed stent implantation after restoration of normal epicardial flow by a minimalist immediate mechanical intervention aims to decrease the rate of distal embolization and impaired myocardial reperfusion after percutaneous coronary intervention. We sought to confirm whether a delayed stenting (DS) approach (24-48 hours) improves myocardial reperfusion, versus immediate stenting, in patients with acute ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. ⋯ URL: http://www.clinicaltrials.gov.
