Transcatheter edge-to-edge repair for mitral regurgitation using PASCAL or MitraClip.
Catheter Cardiovasc Interv
September 2023
Background: There is a paucity of data regarding the comparative efficacy and safety of Mitral valve transcatheter edge-to-edge repair (MTEER) using the PASCAL or MitraClip systems for patients with mitral regurgitation (MR).
Methods: An electronic search was conducted for MEDLINE, COCHRANE, and EMBASE, through February 2023, for studies comparing the clinical outcomes of MTEER using PASCAL versus MitraClip systems among patients with severe MR. The primary study outcome was residual MR ≤ 2 at discharge.
Background In-stent restenosis (ISR) is commonly encountered even in the era of contemporary percutaneous coronary intervention (PCI). There is a paucity of data on the comparative outcomes of PCI for ISR lesions versus de novo lesions. Methods and Results An electronic search was conducted for MEDLINE, Cochrane, and Embase through August 2022 for studies comparing the clinical outcomes after PCI for ISR versus de novo lesions.

Aims: To examine the comparative efficacy and safety of FFR-guided versus angiography-guided revascularisation among patients with obstructive CAD.
Methods: An electronic search of MEDLINE, SCOPUS and Cochrane databases without language restrictions was performed through November 2021 for randomised controlled trials that evaluated the outcomes of FFR-guided versus angiography-guided revascularisation.
Objectives: The aim of this study was to examine the efficacy and safety of fractional flow reserve (FFR)-guided versus angiography-guided approaches for nonculprit stenosis among patients with acute ST-segment elevation myocardial infarction (STEMI) and multivessel disease.
Background: The optimal strategy to guide revascularization of nonculprit stenosis among patients with STEMI and multivessel disease remains uncertain.
Methods: Electronic databases were searched for randomized trials evaluating the outcomes of culprit-only revascularization, angiography-guided complete revascularization (CR), or FFR-guided CR.
Trends in utilization, outcomes, and readmissions after transcatheter mitral valve replacement.
Catheter Cardiovasc Interv

Article Synopsis
- - The study analyzed data from the Nationwide Readmissions Database (2015-2018) to assess trends and outcomes for trans-septal transcatheter mitral valve replacement (TS-TMVR) in the U.S., noting a significant increase in procedures from 48 in 2015 to 978 in 2018, especially among women and diabetic patients.
- - Despite the rise in procedures and performing centers, the overall in-hospital mortality rate (7.2%) and the frequency of complications remained stable, with a median hospital stay decreasing over time.
- - The main causes for 30-day readmissions were acute heart failure, bleeding, and infections, with certain risk factors like prior coagulopathy linked to
