Aortic stenosis (AS) is the most common age-related valvular condition with a prevalence of 13.1% in patients older than 75 years of age. Based on the severity of AS and symptoms, current guidelines recommend interval monitoring with transthoracic echocardiogram (TTE).

With increasing use of non-gated CT scans in clinical practice, the visual coronary artery scoring system (Weston Method) could quickly provide clinicians with important information of CAC for patient triage and management. We retrospectively studied the available CT imaging data and estimated CAC burden using the Weston method in 493 emergency room or other hospitalized patients.

Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a polyester graft (Dacron) using the graft inclusion technique. He presented currently in cardiogenic shock.

Background: RGs and HGs are objective tools in defining the hemodynamic significance of an arterial stenosis.
Methods: In 25 subjects with infrainguinal arterial stenosis, RG and HG were measured via a pressure wire before and after angioplasty.
Aortic dissection is the most common fatal condition of the aorta, yet it is often missed on initial clinical presentation. Aortic dissection associated with acute coronary syndrome (ACS) is relatively rare, but if it occurs, it can be diagnostically challenging, and the condition can be fatal. Here we describe a case of aortic dissection presenting as ST-segment elevation myocardial infarction (STEMI) managed via the transradial approach.

Background: CTOs are one of the most challenging complex coronary lesion subsets to intervene upon.
Objectives: To compare outcomes of elective percutaneous coronary interventions (PCI) in same-day discharge and overnight hospital stays.
Background: Advances in PCI techniques and equipment have allowed same-day discharge after elective PCI. In this study, we investigated the safety of same-day discharge ambulatory PCI in patients according to age, creatinine, and ejection fraction (ACEF) scores.

Statins do not appear to have a significant benefit in heart failure (HF) as they do in coronary artery disease (CAD). Significant evidence exists that low serum cholesterol levels may be harmful in HF. This study sought to determine the optimal low-density lipoprotein (LDL) level in patients hospitalized with acute HF.

Left main coronary artery (LMCA) disease remains an important risk factor for increased mortality and morbidity at all stages of diagnosis and treatment of coronary artery disease. Left main stem pathology is often silent, with unpredictable presentation: as such it poses diagnostic and management challenges. This article reviews the anatomy, epidemiology and diagnosis of left main stem disease, as well as advances in multidisciplinary concepts of diagnosis and management, and summarises the outcomes of recent prospective studies comparing percutaneous and surgical revascularisation in LMCA disease.

Objectives: We assessed image quality, radiation dose, and diagnostic accuracy of a low-dose, prospectively gated axial cardiac CT angiography protocol for the evaluation of patients with suspected coronary artery disease (CAD).
Methods: Fifty consecutive patients referred for diagnostic invasive coronary angiography (ICA) and with a stable heart rate < 60 beats/min after beta-blocker administration were prospectively enrolled in a single center study.
Objectives: We studied the use of 8 Fr Angio-Seal in closure of access sites up to 10 Fr.
Background: The use of larger French catheters for procedures such as valvuloplasty and percutaneous valve replacement has required the use of better methods for arterial closure. The use of 6 and 8 Fr Angio-Seal hemostatic devices (St.
Fibrillar collagens are the principal structural molecules of connective tissues. The assembly of collagen fibrils is regulated by quantitatively minor fibrillar collagens, types V and XI. A unique amino-terminal propeptide domain of these collagens has been attributed this regulatory role.
