PMID: 27118056
Background: Chronic total occlusions (CTOs) of native coronary arteries are a frequent finding among patients who are referred for surgical revascularization with coronary artery bypass grafting (CABG). The long-term clinical...

. 2015 Nov;
87(6):1063-70.
PMID: 26602868
Background: Gender differences exist in the presentation and outcomes of patients with coronary artery disease (CAD). Our study objective was to compare gender differences in prevalence, co-morbidities, and revascularization treatment...

JACC Cardiovasc Interv
. 2014 Jul;
7(7):761-7.
PMID: 25060019
Objectives: The aim of the study was to determine native coronary artery patency 1 year after coronary artery bypass grafting and to identify clinical and angiographic predictors for the development...

Am J Cardiol
. 2013 Dec;
113(4):607-12.
PMID: 24332697
The specific mechanisms by which diabetes may affect the myocardial tissue response to ischemia are unclear. Our objective was to prospectively quantify the degree of myocardial edema in diabetics versus...

EuroIntervention
. 2013 Jan;
8(9):1081-9.
PMID: 23339813
Aims: Percutaneous revascularisation of chronic total occlusions (CTO) is limited by failure of guidewire crossing. Neovascularisation within the proximal CTO segment may be important for guidewire crossing and dramatically declines...

Circ Cardiovasc Imaging
. 2012 Jun;
5(5):566-72.
PMID: 22744938
Background: Accurate characterization of the longitudinal trends of myocardial edema and hemorrhage has been previously limited by subjective qualitative methods. We aimed to prospectively characterize the evolution of myocardial edema...

Atherosclerosis
. 2012 Apr;
223(1):106-13.
PMID: 22503825
Background: Venous grafts (VG) have high failure rates by 10 years in aortocoronary bypass surgery. We have previously shown that expansive remodeling followed by increased LDL retention are early atherosclerotic...

Circulation
. 2011 Dec;
125(3):522-8.
PMID: 22179536
Background: Percutaneous interventions for chronic total occlusions have low success rates, primarily because of failure of guide wire crossing. Collagen-rich matrix constitutes the main barrier to chronic total occlusion crossing....
