Multicenter StudyOutcomes of Redo Transcatheter Aortic Valve Replacement for the Treatment of Postprocedural and Late Occurrence of Paravalvular Regurgitation and Transcatheter Valve Failure.
Transcatheter aortic valves can degenerate in a manner similar to surgical bioprostheses. ⋯ Redo TAVR for the treatment of postprocedural and late occurrence of paravalvular regurgitation and transcatheter aortic valve prosthesis failure seems to be safe, and it is associated with favorable acute and midterm clinical and echocardiographic outcomes.

Comparative StudyCoronary Plaque Characteristics Associated With Reduced TIMI (Thrombolysis in Myocardial Infarction) Flow Grade in Patients With ST-Segment-Elevation Myocardial Infarction: A Combined Optical Coherence Tomography and Intravascular Ultrasound Study.
Previous studies reported that reduced TIMI (Thrombolysis in Myocardial Infarction) flow grade before procedure was associated with worse clinical outcomes in patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. The aim of this study was to identify specific morphological characteristics of the culprit plaque associated with poor TIMI flow grade at baseline in patients with ST-segment-elevation myocardial infarction using both optical coherence tomography and intravascular ultrasound. ⋯ ST-segment-elevation myocardial infarction patients with reduced TIMI flow grade at baseline have greater lipid burden, larger vessel sizes, and larger plaque areas.

Multicenter Study Comparative Study Observational StudyPharmacoinvasive Strategy Versus Primary Percutaneous Coronary Intervention in Patients With ST-Segment-Elevation Myocardial Infarction: A Propensity Score-Matched Analysis.
The Strategic Reperfusion Early After Myocardial Infarction trial and the French Registry of Acute ST-elevation or Non-ST-elevation Myocardial Infarction 2015 suggested that pharmacoinvasive strategy compares favorably with primary percutaneous coronary intervention (PPCI). We sought to assess the clinical impact of pharmacoinvasive strategy compared with PPCI in real-world patients with ST-segment-elevation myocardial infarction. ⋯ ST-segment-elevation myocardial infarction patients receiving pharmacoinvasive treatment, compared with PPCI, had shorter time to reperfusion, higher culprit-vessel patency, and similar 12-month clinical outcome.

Validation of the Coronary Artery Bypass Graft SYNTAX Score (Synergy Between Percutaneous Coronary Intervention With Taxus) as a Prognostic Marker for Patients With Previous Coronary Artery Bypass Graft Surgery After Percutaneous Coronary Intervention.
The efficacy and prognosis of percutaneous coronary intervention (PCI) as secondary revascularization in patients with previous coronary artery bypass graft surgery remain uncertain. ⋯ In this external validation study, the CSS was a potential prognostic factor after subsequent PCI, even for previous coronary artery bypass graft surgery patients.
