Prospective application of pre-defined intravascular ultrasound criteria for assessment of intermediate left main coronary artery lesions results from the multicenter LITRO study.

Objectives: This study is a prospective validation of 6 mm(2) as a minimum lumen area (MLA) cutoff value for revascularization of left main coronary artery (LMCA) lesions.

Background: Lesions involving the LMCA are prognostically relevant. Angiography has important limitations in the evaluation of LMCA lesions with intermediate severity.

Clinical outcomes of dexamethasone-eluting stent implantation in ST-elevation acute myocardial infarction.

Objectives: The aim of our study was to evaluate the safety and midterm clinical results of dexamethasone-eluting stent (DexES) implantation in ST-segment elevation acute myocardial infarction (STEMI).

Background: Inflammation plays a pivotal role in both inestabilization of coronary atherosclerotic plaques and development of restenosis after stent placement. Antiinflammatory agents may attenuate those mechanisms and improve clinical outcomes.

[Anomalous coronary arteries originating in the contralateral sinus of Valsalva: registry of thirteen Spanish hospitals (RACES)].

The registry contains information collected during 2003 from thirteen Spanish hospitals on the incidence, clinical presentation, initial course, diagnostic imaging, and treatment of anomalous coronary arteries originating in the contralateral coronary sinus. In a total of 23,300 coronary angiograms, 98 anomalous coronary arteries were detected (incidence 0.4%): 46 circumflex coronary arteries (47%), 25 right coronary arteries (25.
