Arrhythmogenic right ventricular dysplasia/cardiomyopathy presenting as ST-segment elevation myocardial infarction: a case report.

Diagnosis of arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is often challenging due to differing clinical presentations and unpredictable progression of the disease. We report a case of ARVD/C that presented as cardiac arrest in an 18-year-old male while playing soccer. The electrocardiographic features after resuscitation were typical of anterior ST-segment elevation acute myocardial infarction, and the patient was initially managed accordingly.

Safety of percutaneous left heart catheterization directly performed by cardiology fellows: a cohort analysis.

Background: No previous study has analyzed the possible responsibility of fellows-in-training in terms of the risk of complications during cardiac catheterization. Thus, we sought to identify possible risk factors for access site complications following cardiac catheterization procedures, with particular attention to the role of cardiology fellows.

Methods: A total of 1,288 left heart catheterization procedures (both diagnostic and interventional), performed over a 1-year period at a university hospital, were retrospectively evaluated to determine the incidence of local complications (pseudoaneurysm, arterio-venous fistula, major hematoma or bleeding, vascular dissection).

Clinical effectiveness of bare-metal stenting compared with balloon angioplasty in total coronary occlusions: insights from a systematic overview of randomized trials in light of the drug-eluting stent era.

Background: We sought to compare, using meta-analytic techniques, bare-metal stent versus balloon angioplasty in the percutaneous treatment of total coronary occlusions by means of a quantitative systematic review and to indicate new avenues for future treatments.

Methods: MEDLINE and CENTRAL were searched. Inclusion criteria were random allocation, prospective comparison, and intention to treat.

Safety and efficacy of the percutaneous radial artery approach for coronary angiography and angioplasty in the elderly.

Background: The transradial approach to coronary interventions has been accepted as a safe and effective alternative to the femoral approach due to fewer access site complications and improved patient comfort. In the present study we aimed to investigate the safety and efficacy of transradial procedure in the elderly.

Methods: We analyzed 850 patients who underwent transradial coronary angiography and/or angioplasty.

Plasma levels of oxidized-low-density lipoproteins are higher in patients with unstable angina and correlated with angiographic coronary complex plaques.

Objectives: To measure circulating levels of oxidized-low-density lipoproteins (ox-LDL) in patients with stable and unstable angina and controls, and to investigate their correlation with the extent of coronary artery disease (CAD) and the presence of complex plaques at coronary angiography.

Methods And Results: Circulating ox-LDL were assessed, using ELISA, in patients with unstable angina (UA, n=26), stable angina (SA, n=29) and in controls (C, n=27). All patients underwent coronary angiography.

Is bare-metal stenting superior to balloon angioplasty for small vessel coronary artery disease? Evidence from a meta-analysis of randomized trials.

Aims: To compare, by meta-analytical techniques, the clinical impact of bare-metal stenting vs. balloon angioplasty for the treatment of lesions in small coronary arteries.

Methods And Results: We included trials with random allocation and prospective comparison of angioplasty vs.

Radial versus femoral approach for percutaneous coronary diagnostic and interventional procedures; Systematic overview and meta-analysis of randomized trials.

Objectives: We sought to compare, through a meta-analytic process, the transradial and transfemoral approaches for coronary procedures in terms of clinical and procedural outcomes.

Background: The radial approach has been increasingly used as an alternative to femoral access. Several trials have compared these two approaches, with inconclusive results.

Stenting versus surgical bypass grafting for coronary artery disease: systematic overview and meta-analysis of randomized trials.

Background: Coronary angioplasty and coronary artery bypass grafting (CABG) are both major techniques for the management of coronary artery disease, but CABG is associated with a lower incidence of repeat revascularization. Recent studies comparing angioplasty with stenting vs CABG have yielded conflicting results, with some suggesting improved survival with stenting, and others the opposite. We thus undertook a systematic overview of the randomized trials comparing stenting vs CABG in coronary artery disease.
