Optimal timing for aortic valve replacement in symptomatic patients with less than severe aortic stenosis (AS) is not well defined. There is limited information on the benefit of valve replacement in these patients. Symptomatic patients with less than severe AS, defined as a mean aortic gradient ≥20 and <40 mm Hg, peak aortic velocity >3 and <4 m/s, and aortic valve area >1.

We aimed to evaluate AS natural history, compare outcomes for physicians' AS assessment vs. quantitative parameters, and identify AS parameters with the most explanatory power.
View Article and Find Full Text PDFBackground: Transcatheter aortic valve replacement (TAVR) may be used to urgently or emergently treat severe aortic stenosis, but outcomes for this high-risk population have not been well-characterized. We sought to describe the incidence, clinical characteristics, and outcomes of patients undergoing urgent or emergent vs. elective TAVR.
View Article and Find Full Text PDFBackground: Data on the epidemiology of aortic stenosis (AS) are primarily derived from single center experiences and administrative claims data that do not delineate by degree of disease severity.
Methods: An observational cohort study of adults with echocardiographic AS was conducted January 1st, 2013-December 31st, 2019 at an integrated health system. The presence/grade of AS was based on physician interpretation of echocardiograms.
Background: The relative safety of drug-eluting stents (DES) and bare-metal stents (BMS) in primary percutaneous coronary intervention (PPCI) in ST elevation myocardial infarction (STEMI) continues to be debated. The long-term clinical outcomes between second generation DES and BMS for primary percutaneous coronary intervention (PCI) using network meta-analysis were compared.
Methods: Randomized controlled trials comparing stent types (first generation DES, second generation DES, or BMS) were considered for inclusion.
Background: The optimal management for coronary drug eluting stent in-stent restenosis (DES ISR) is unclear. We performed a meta-analysis of observational and randomized studies to compare the outcomes of management of DES ISR using DES, drug eluting balloon (DEB), or balloon angioplasty (BA).
Methods: Eligible studies (25 single arm and 13 comparative, including 4 randomized studies with a total of 7,474 patients with DES ISR) were identified using MEDLINE search and proceedings of international meetings.
Aortic atherosclerosis has been linked with worse peri- and post-procedural outcomes following a range of aortic procedures. Yet, there are currently no standardized methods for non-invasive volumetric pan-aortic plaque assessment. We propose a novel means of more accurately assessing plaque volume across whole aortic segments using computed tomography angiography (CTA) imaging.

We sought to characterize the aortic root and annulus in bicuspid aortic valve (BAV) and tricuspid aortic valves (TAV).
Methods And Results: We identified patients with severe AS who underwent multi-detector computed tomographic (MDCT) imaging prior to surgical aortic valve replacement (SAVR, n = 200) for BAV and TAVR (n = 200) for TAV from 2010 to 2013.

Background: We conducted a retrospective cohort study of patients after first-time isolated coronary artery bypass graft surgery (CABG) and assessed the impact of a discharge regimen including beta-blockers and statin therapy and their relationship to long-term all cause mortality and major adverse cardiovascular events (MACE).
Methods: We identified patients age >18 years, undergoing first time isolated CABG from 1993 to 2005. Patients were identified using the Cardiovascular Information Registry (CVIR).
Objective: To assess the relationship between the development of transient post-operative atrial fibrillation (TPOAF) following coronary artery bypass graft (CABG) surgery and risk of long-term mortality.
Background: Atrial fibrillation (AF) following CABG is common and associated with increased morbidity and mortality in the perioperative period. However the impact of TPOAF and its management on long-term morbidity and mortality in patients undergoing first time, isolated CABG surgery remains unclear.
Background: The optimal treatment of patients with severe mitral regurgitation (MR) at high surgical risk (HSR) is unknown. Recently, the EVEREST II (Endovascular Valve Edge-to-Edge Repair) High Risk Study suggested MitraClip (MC) was a safe and effective treatment option.
Methods: We performed a search strategy for MC or mitral valve surgery (MVS) in patients at HSR for surgical mortality (logistic EuroSCORE >18 or STS score > 10) using Medline databases, proceedings of international meetings, and the STS database.
Background: The relative safety of drug-eluting stents (DESs) and bare-metal stents (BMSs) with respect to stent thrombosis (ST) continues to be debated. There are limited data comparing safety and efficacy of second-generation DES to BMS. We compared the clinical outcomes between second-generation DES and BMS for primary percutaneous coronary intervention using network meta-analysis.
View Article and Find Full Text PDFObjectives: The aim of this study was to assess the impact of atherosclerotic renal artery stenosis (ARAS) on outcomes after open-heart surgery (OHS).
Background: Acute kidney injury after OHS portends significant morbidity and mortality.
Methods: Data from all adult patients undergoing OHS from January 2000 to April 2010 who underwent renal duplex ultrasound were prospectively collected.
Objective: To compare multi-detector computed tomography (MDCT) and aortography in the assessment of the internal pudendal artery (IPA) anatomy and degree of atherosclerosis.
Methods: Eighty-three patients underwent MDCT and aortography of the pelvic vasculature prior to consideration for transcatheter aortic valve replacement. These modalities were used to localize the IPA origin, degree of stenosis (normal: <50% stenosis or abnormal: >50% stenosis or occlusion), normal= and extent of calcification, quantified using a nominal scale (0 = no calcification, 1 = <25%, 2 = 25-50%, 3 = >50% of the IPA length).

Normal erectile function requires adequate penile arterial inflow, normal penile architecture and an intact venous capacitance system. Vascular disease is the dominant etiology of erectile dysfunction (ED) and current medical therapy increases penile blood flow. However, in a large proportion of patients, medical therapy is inadequate or contraindicated requiring the use of mechanical constrictive devices or implantation of a penile prosthesis.
