Development and validation of a clinical risk score to predict mortality after percutaneous coronary intervention.

Objective: To develop and validate a contemporary clinical risk score to predict mortality after percutaneous coronary intervention (PCI).

Methods: Using data collected from patients undergoing PCI at the South Yorkshire Cardiothoracic Centre, Sheffield, UK, between January 2007 and September 2013, a risk score was developed to predict mortality. Logistic regression was used to evaluate the effect of each variable upon 30-day mortality.

Residual SYNTAX score after PCI for triple vessel coronary artery disease: quantifying the adverse effect of incomplete revascularisation.

Aims: There is some evidence to suggest that incompleteness of coronary artery revascularisation after PCI is associated with inferior outcomes. The SYNTAX score was developed as a tool to quantify the extent of coronary artery disease in the SYNTAX study. We aimed to use this score to quantify the completeness of revascularisation after PCI (the "residual SYNTAX score") and to determine its impact upon mortality.

Simultaneous kissing drug-eluting stents to treat unprotected left main stem bifurcation disease: medium term outcome in 150 consecutive patients.

Aims: Percutaneous coronary intervention (PCI) is increasingly being used to treat left main stem (LMS) coronary artery disease. Disease at the LMS bifurcation is technically challenging to treat, and there is no consensus as to the best method. We previously described experimental and initial clinical results with the simultaneous kissing stents (SKS) technique in a small series using drug-eluting stents (DES).

Impact of incomplete revascularization in patients undergoing PCI for unprotected left main stem stenosis.

Introduction: Percutaneous revascularization of patients with multivessel and left main stem (LMS) disease may be incomplete and the impact of this is not well reported and may influence outcome. In this study we assessed the role of completeness of revascularization upon outcome after PCI for unprotected left main stem (uLMS) PCI in the "real world."

Materials And Method: Consecutive patients (n = 353) with uLMS disease were treated by PCI by a single operator with a policy of maximal feasible revascularization between 2000 and 2011.
