BACKGROUND AND OBJECTIVE: With aging, the progression of atherosclerosis in the coronary arteries is expected. The Medtronic™ self-expandable aortic bioprosthetic valve is deployed in the supra-annular position, and it has been challenging to selectively engage coronary arteries post-transcatheter aortic valve replacement (TAVR) even though there are diamond-shaped spaces in the mesh frame within the valve. Given the scarcity of data, we analyzed angiographic and clinical data from all patients requiring coronary angiography (CA) or intervention post-TAVR...

performing percutaneous coronary intervention (PCI) following transcatheter aortic valve implantation (TAVI) will become more frequent with the increasing use of TAVI in lower surgical risk populations. The ideal management strategy for coronary artery disease (CAD) in the setting of TAVI is not well defined and CAD is often left untreated prior to TAVI. Engaging the coronary ostia through the TAVI side cells can be challenging; techniques for rapid coronary cannulation, especially in the acute setting, need to be developed...

The safety and utility of GuideLiner catheters in complex percutaneous coronary interventions (PCI) has been well established. Patients with prior trans-catheter aortic valve replacement especially with CoreValve, who present for PCI, pose a unique set of challenges. Not only does the operator often encounter difficulty with selective engagement of coronary ostia through the struts of the CoreValve, but also the complex nature of the underlying CAD in this high-risk population. We present a case series to illustrate the use of GuideLiner catheter as an adjunctive tool for PCI in this patient population...

Pseudomonas aeruginosa (PA) is an opportunistic pathogen with an exceptional ability to adapt to a range of environments. Part of its adaptive potential is the ability to survive drastic osmolarity changes. Upon a sudden dilution of external medium, such as during exposure to rain, bacteria evade mechanical rupture by engaging tension-activated channels that act as osmolyte release valves. In this study, we compare fast osmotic permeability responses in suspensions of wild-type PA and Escherichia coli (EC) strains in stopped-flow experiments and provide electrophysiological descriptions of osmotic-release channels in PA...

We present a case of a geriatric male with giant ascending aortic aneurysm (AAA) who underwent successful coronary angiography using telescoping technique for evaluation his coronary arteries before surgery for AAA. Since the ascending aorta and root were extremely dilated, we knew it would not have been possible to engage the coronaries using regular catheters and standard technique. Hence, telescopic technique was used. Amplatz left 3 (AL3) 7F (French) guide catheter (90 cm) was initially used, and nonselective injection of contrast was done to see the coronary ostium...

OBJECTIVES: Comprehension of risks, benefits, and alternative treatment options has been shown to be poor among patients referred for cardiac interventions. Patients' values and preferences are rarely explicitly sought. An increasing proportion of frail and older patients are undergoing complex cardiac surgical procedures with increased risk of both mortality and prolonged institutional care. We sought input from patients and caregivers to determine the optimal approach to decision making in this vulnerable patient population...

Atrial fibrillation is the most common cardiac arrhythmia and conveys a significant risk of morbidity and mortality due to related stroke and systemic embolism. Oral anticoagulation (OAC) is the mainstay of thromboembolism prevention, and management of anticoagulation can be challenging. For patients without significant valvular disease, decisions around anticoagulation therapy are first based on the presence of additional stroke risk factors, as measured by the CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75, diabetes, prior stroke or transient ischemic attack, vascular disease, age 65-74, and sex category [female]) score...

The Engager aortic bioprosthesis consists of bovine pericardial leaflets mounted on a self-expandable frame with unique anatomic orientation capabilities to engage the aortic valve cusps. We report the initial North American transcatheter aortic valve implantation (TAVI) experience with the Engager device. Transapical TAVI was performed in 4 patients (mean age 80 ± 6 years, Society of Thoracic Surgeons score 5 ± 1%). The valve was anatomically oriented and successfully implanted in all patients. There were no conversions to open operation or major procedure-related adverse events...

Transcatheter aortic valve replacement (TAVR) has become an established treatment for patients with severe aortic stenosis and high surgical risk. Ten years of technological advances in valve structure and delivery systems alongside growing operator and centre experience has opened TAVR implantation to an increasingly broad range of patients. The extension to off-label use however needs careful consideration and monitoring. Through discussion of our case involving an inoperable 24-year-old male with severe aortic regurgitation (AR), we highlight the need for an experienced and multidisciplinary team, together with early and extensive patient and family disclosure and engagement, prior to considering any off-label application of TAVR...

OBJECTIVES: Transcatheter aortic valve replacement (TAVR) is an established therapy for patients with aortic stenosis (AS) at high surgical risk. The JenaValve™ is a second-generation, self-expanding transcatheter heart valve (THV), implanted through transapical access (TA). During stent deployment, a specific 'clipping-mechanism' engages native aortic valve cusps for fixation. We present 1-year outcomes of the JUPITER registry, a post-market registry of the JenaValve for TA-TAVR. METHODS: The JUPITER registry is a prospective, multicentre, uncontrolled and observational European study to evaluate the long-term safety and effectiveness of the Conformité Européenne-marked JenaValve THV...

BACKGROUND: Gastroesophageal reflux disease (GERD) is defined by the intensity and/or quality of the reflux of gastric or duodenal contents into the esophagus. Surgical treatment of GERD has shown conflicting results and unacceptable recurrence rates, mainly due to herniation of the antireflux valve into the chest. A variety of techniques has been proposed to reduce GERD recurrence, including routine use of prosthesis in cruroplasty. The prevalence of GERD in patients with hiatal hernia (HH) can reach 94 %...

Transcatheter aortic valve implantation (TAVI) is a relatively new procedure to treat aortic stenosis in patients at high surgical risk, and it is becoming increasingly available in Canada. Variation exists in the clinical care, program coordination, evaluation, and funding across provinces and centres. As a part of the Canadian Cardiovascular Society (CCS) quality initiative, the TAVI Quality Indicator (QI) Working Group was established in 2014 to develop a set of indicators to measure quality of care for Canadians undergoing TAVI for aortic stenosis...

In Titan's atmosphere, photochemical pathways that lead to nitrogen heteroaromatics may incorporate photoisomerization of their structural isomers as a final step. (E)- and (Z)-phenylvinylnitrile ((E)- and (Z)-PVN, C6H5-CH=CHCN) are structural isomers of quinoline that themselves possess extensive absorptions in the ultraviolet, and thus may engage in such photoisomerization pathways. The present study explores the vibronic spectroscopy and photo-induced isomerization of gas-phase (E)- and (Z)-PVN in the 33,600-35,850 cm(-1) region under jet-cooled conditions...
