A case of mid-apical obstructive hypertrophic cardiomyopathy treated with a transapical myectomy approach: a case report.

Introduction: Hypertrophic cardiomyopathy is a genetic cardiac disease characterized by marked variability in morphological expression and natural history. The hypertrophic myocardium is often confined to the septum or lateral wall of the left ventricle, but it can also be encountered in the middle or apical segments of the myocardium. Treatment is based on medical therapy.

Comparison between off-pump and on-pump coronary artery bypass grafting in patients with severe lesions at the circumflex artery territory: 5-year follow-up of the MASS III trial.

Objectives: The technical difficulty in the revascularization of the circumflex artery territory with off-pump surgery may compromise the outcome of this method in clinical follow-up. We aimed to evaluate cardiac events in patients with stable coronary artery disease and severe obstruction of the circumflex system, undergoing coronary artery bypass grafting (CABG) with or without cardiopulmonary bypass.

Methods: MASS III was a single-centre study that evaluated 308 patients with multivessel coronary artery disease randomized to on-pump (153) or off-pump (155) CABG.

Hypotheses, rationale, design, and methods for evaluation of ischemic preconditioning assessed by sequential exercise tests in diabetic and non-diabetic patients with stable coronary artery disease--a prospective study.

Background: Ischemic preconditioning is a powerful mechanism of myocardial protection and in humans it can be evaluated by sequential exercise tests. Coronary Artery Disease in the presence of diabetes mellitus may be associated with worse outcomes. In addition, some studies have shown that diabetes interferes negatively with the development of ischemic preconditioning.

Hypotheses, rationale, design, and methods for prognostic evaluation of cardiac biomarker elevation after percutaneous and surgical revascularization in the absence of manifest myocardial infarction. A comparative analysis of biomarkers and cardiac magnetic resonance. The MASS-V Trial.

Background: Although the release of cardiac biomarkers after percutaneous (PCI) or surgical revascularization (CABG) is common, its prognostic significance is not known. Questions remain about the mechanisms and degree of correlation between the release, the volume of myocardial tissue loss, and the long-term significance. Delayed-enhancement of cardiac magnetic resonance (CMR) consistently quantifies areas of irreversible myocardial injury.

Budd-Chiari syndrome in a 25-year-old woman with Behçet's disease: a case report and review of the literature.

Introduction: The risk that patients with Behçet's disease will develop thrombotic complications has been previously described. Although it is distributed worldwide, Behçet's disease is rare in the Americas and Europe. Even though the pathogenic mechanisms of vascular complications of Budd-Chiari syndrome in patients with Behçet's disease are unknown, severe vascular complications of Budd-Chiari syndrome associated with Behçet's disease seem to affect mainly young men.
