Four-year outcomes of a single-center experience with coronary everolimus-eluting bioresorbable scaffolds.

Background: Bioresorbable scaffolds (BRS) have been introduced to overcome the limitations of drug-eluting stents and the ABSORB (Everolimus-Eluting BRS, Abbott Vascular, Santa Clara, CA, USA) was the most extensively tested. Nevertheless, major RCTs reported higher rates of target lesion failures and BRS thrombosis at 3 years follow-up, bringing to the withdrawing of the device from the market. It has been suggested that a better lesions selection and an optimized implantation technique could mitigate the displayed adverse results.

Training-induced right ventricular remodelling in pre-adolescent endurance athletes: The athlete's heart in children.

Aims: Little is known about the adaptation of the right ventricle (RV) to endurance exercise in children. The aim of this study was to assess the effects of 5months of intensive training on RV morphology and function in preadolescent endurance athletes.

Methods: Ninety-four children were evaluated in this study.

Electrocardiographic Changes Induced by Endurance Training and Pubertal Development in Male Children.

Training-induced electrocardiographic changes are common in adult athletes. However, a few data are available on electrocardiogram (ECG) in preadolescent athletes and little is known about the potential changes induced by training on 12-lead electrocardiogram (ECG) at rest. Twelve-lead ECGs at rest and complete echocardiographic examinations were performed in 94 children (57 endurance athletes, 37 sedentary controls; mean age 10.

Optical coherence tomography evidence of endothelial erosion as a cause of ST-segment elevation myocardial infarction.

High-resolution intracoronary imaging provided relevant insights into the field of pathophysiology of acute coronary syndromes (ACS). Human autopsy studies have shown that endothelial erosion may lead to intravascular thrombosis and acute myocardial infarction. We report the case of a 51-year-old woman presenting with ST-segment elevation ACS.

Acute ST elevation myocardial infarction in pregnancy due to coronary vasospasm: a case report and review of literature.

Acute myocardial infarction during pregnancy is rare but may be associated with high risk complications. We present a very rare case about an acute myocardial infarction with anterior ST elevation in a 40-year-old woman, at 38th week of gestational period. The coronary arteriograms showed a diffuse left coronary vasospasm.

Hand-held echocardiography: added value in clinical cardiological assessment.

Background: The ultrasonic industry has recently produced echocardiographic Hand Held Devices (miniaturized, compact and battery-equipped echocardiographic systems). Their potential usefulness has been successfully assessed in a wide range of clinical conditions. The aim of the study was to verify if the routine use of a basic model of echocardiographic Hand Held Device (HHD) could be an important diagnostic tool during outpatient cardiologic consulting or in non-cardiologic hospital sections.

Midwall mechanics in physiologic and hypertensive concentric hypertrophy.

Objective: We sought to analyze and compare midwall fractional shortening (mFS), and its relations with circumferential end-systolic stress (cESS) and relative wall thickness (RWT), among subjects with physiologic concentric left ventricular (LV) hypertrophy, patients with hypertension and concentric LV hypertrophy, and control subjects.

Methods: A total of 51 normotensive athletes and 56 young patients with hypertension and echocardiographic evidence of concentric LV hypertrophy were enrolled. In addition, 49 age- and sex-matched control subjects were recruited.

Effects of simvastatin on walking performance and symptoms of intermittent claudication in hypercholesterolemic patients with peripheral vascular disease.

Purpose: To analyze the effects of short-term therapy with simvastatin on walking performance in hypercholesterolemic patients with peripheral vascular disease.

Methods: Eighty-six patients with peripheral arterial disease (Fontaine stage II), intermittent claudication, and total cholesterol levels >220 mg/dL were enrolled in a randomized, placebo-controlled, double-blind study. Forty-three patients were assigned to simvastatin (40 mg/d); the remaining 43 patients were assigned to placebo treatment.

Spontaneous acute coronary dissection after cocaine abuse in a young woman.

Spontaneous coronary artery dissection is an unusual trigger for acute coronary syndrome or sudden death, occurring more frequently in relatively young people and mainly in the female sex. The underlying mechanism is not completely understood, but predisposing factors may include metabolism and collagen synthesis disorders. The case of a 34-year-old woman who underwent coronary angiography for acute anterolateral myocardial ischemia after cocaine abuse is reported.
