Coronary artery atherosclerosis is a major cause of sudden cardiac
death (SCD) in the young, accoun ting for nearly 25% of fatalitie s in
this age group (≤40 years old) [1]. Interestingl y, the composition of
the culprit atherosclerotic plaque in young subjects often shows a pecu-
liar morphology, consisting predominantly of smooth muscle cells
(SMCs) with a variable amount of extracellular matrix, and minimal
or absent lipid core [2] leading to the definition of “non-atheromatous

Background-Digoxin use was shown to be associated with an increased risk of cardiovascular events in atrial fibrillation (AF). We hypothesized that digoxin may affect cardiovascular risk by increasing platelet activation. Methods and Results-Post hoc analysis of a prospective study of anticoagulated patients with AF. Patients were divided into 2 groups balanced for age, sex, and cardiovascular risk factors: digoxin users (n=132) and nonusers (n=388). Urinary excretion of 11‐dehydro‐thromboxane B2 (TxB2), a marker of platelet activation, and serum digoxin concentration (SDC) were measured.

Background and aims: Antioxidant status has been shown to be associated with cardiovascular events (CVEs). The aim of the study was to develop an assay measuring serum hydrogen peroxide (H2O2) break-down activity (HBA) of healthy subjects (HS) and to validate it in a cohort of patients with atrial fibrillation (AF). Methods: We developed the HBA assay in 121 HS and validated it in 842 AF patients. The occurrence of CVEs was registered and correlated with HBA in AF during a median follow-up of 30.6 months (3226 patient-years).

BACKGROUND:
When the common femoral artery is not accessible for infrainguinal bypass grafting, the profunda femoris artery (PFA) can be a valuable alternative inflow source for distal arterial revascularization. The purpose of this retrospective study was to evaluate the results of infrageniculate bypass grafting via the PFA as inflow source for critical limb ischemia.
METHODS:

The last two centuries have witnessed countless discoveries in the field of medicine that found their roots in the up growing development of technology as well as in the visionary ideas of brilliant scientists and research groups. One of the most important discoveries in the field of cardiovascular medicine allowed to break the paradigm identifying the heart with mere mechanical pump and to characterize its intriguing endocrine properties.

Thoracic endovascular aortic repair (TEVAR) is a less invasive option for managing traumatic injuries of the descending aorta in polytraumatized patients. Concerns arise when treating young patients with TEVAR. A 22-year-old male was admitted to the emergency department following a high-impact road traffic collision. Whole-body computed tomography (CT) scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke.

Post-pneumonectomy bronchopleural fistula associated with empyema still remains a dreaded complication in thoracic surgery. A variety of surgical and endoscopic procedures have been proposed over the years, but none of these has been suitable for all patients. Herein, we report a new multimodal approach, including the insertion of tracheobronchial conical stent, the open pleural packing, and the closure of bronchial stump with omentoplasty. This procedure was successfully applied in 11 patients with post-pneumonectomy bronchopleural fistula with empyema.

Sub-glottic stenosis may be complex in shape, making challenging its treatment with standard commercially available stents. Personalized stents can lead to successful treatment; however they are not readily available due to the customization waiting time. We report the use of on-site customized temporary silicone stents for difficult benign sub-glottic stenosis in five patients unfit for surgery.
