BACKGROUND: Stroke and transient ischemic attack after transcatheter aortic valve replacement results in significantly higher morbidity and mortality. Severe carotid artery disease may be a contributing factor to this increased risk. We report our technique and outcomes of combined carotid endarterectomy (CEA) with transcatheter aortic valve replacement (TAVR). METHODS: From March 2013 to November 2017 a total of 753 TAVRs were performed at our institution for symptomatic severe aortic stenosis...

BACKGROUND: In severe aortic stenosis, different left ventricle (LV) remodeling patterns as a response to pressure overload have distinct hemodynamic profiles, cardiac function, and outcomes. The most common classification considers LV relative wall thickness and LV mass index to create 4 different groups. A new classification including also end-diastolic volume index has been recently proposed. AIM: To describe the prevalence of the newly identified remodeling patterns in patients with severe aortic stenosis and to evaluate their clinical relevance according to symptoms...

Background: Aortic valve stenosis (AS) is very common in the elderly patients above 80 years. Transcatheter aortic valve replacement (TAVR) in such patients is being increasingly performed. This study sought to assess in-hospital outcome differences between octogenarians and nonagenarians and predictors of mortality in nonagenarians undergoing TAVR with severe AS. Method: The study population was derived from the National Inpatient Sample (NIS) for the years 2012-2014 using ICD-9 CM procedure codes 35...

Background: The ankle-brachial index (ABI) and pulse wave velocity (PWV) are indices of atherosclerosis and arterial stiffness. The Japan-made measuring devices of those indices have spread widely because of their convenience and the significance of the parameters. However, studies that comprehensively discuss the various pitfalls in using these indices are not available. Methods: This study presents several representative pitfalls in using the ABI and brachial-ankle PWV (baPWV) by showing the result sheets of the device, "the Vascular Profiler"...

OBJECTIVES: Ventricular pacemaker stimulation may cause deterioration of hemodynamics in patients with left-ventricular hypertrophy following aortic valve replacement. Since the diastolic function is often impaired, it remains unclear which heart rate best optimizes cardiac output. Low heart rates are suggested to treat impaired diastolic function chronically, but it is possible that cardiac output may be augmented by increasing the heart rate in patients with a fixed stroke volume (SV)...

BACKGROUND: Aortic stenosis is a common form of valvular heart disease which often coexists with hypertension. These diseases represent two distinct forms of left ventricular systolic overload and in combination may be associated with disadvantageous left ventricular remodeling, increased mortality and heart failure. The treatment of hypertension in aortic stenosis remains a challenging problem with limited data to guide clinical practice. METHODS: We performed a comprehensive online literature review to find relevant published literature on the topic of hypertension and aortic stenosis...

Effect of natural complex of cytokines with activity of IL-1, IL-2, IL-6, TNF, MIF, and GTFβ on the structure and metabolism of conduction cardiomyocytes was assessed in the control and under acute experimental aortic stenosis. After systemic administration of the cytokine complex in the control, structural abnormalities were revealed in a relatively low number of conduction cardiomyocytes; their relative number increased in the left ventricle and interventricular septum. When the complex was administered against the background of aortic stenosis, morphological changes in the conduction system were seen in a significant number of cells with their plasma imbibition, especially in the left ventricle and interventricular septum...

BACKGROUND: Current guidelines recommend transcatheter aortic valve replacement (TAVR) in patients with severe symptomatic aortic stenosis (AS) who are not suitable for conventional surgical aortic valve replacement (SAVR). In light of the recent trend in performing TAVR in patients with lower risk profile, we assessed the midterm outcome comparing TAVR and SAVR for the treatment of patients with severe AS at low to intermediate risk. METHODS: PubMed, EBSCO, and Cochrane CENTRAL were systematically searched for randomized controlled trials that reported the clinical outcomes of TAVR versus SAVR in patients at low to intermediate surgical risk with at least 2 years of follow-up...

Persistent left superior vena cava (LSVC) with absent right SVC (RSVC) is a rare congenital anomaly. If undetected, the condition may pose difficulties in central venous catheter insertion, pacemaker electrode insertion, and cannulation during cardiopulmonary bypass. We describe a case of persistent LSVC with absent RSVC, who was diagnosed to have bicuspid aortic valve with aortic stenosis.

Asymmetrical septal occluder device (ASOD) has made percutaneous closure of ventricular septal defect an easy and effective management option. Although there are reports of aortic and tricuspid valvular regurgitation after deployment of ASOD, only few cases of tricuspid stenosis (TS) has been reported so far in the literature. We report a case of malaligned ASOD that occurred after successful device closure resulting in TS along with mild tricuspid and aortic regurgitation requiring surgical retrieval. Transesophageal echocardiography played crucial role in detecting the cause of tricuspid valve dysfunction besides providing continuous monitoring during the procedure...

Introduction: Ultrafast tracking of anesthesia (UFTA) is practiced routinely, whereas immediate on-table extubation after off-pump coronary artery bypass (OPCAB) grafting surgery has many concerns. The purpose of our study was to evaluate the safety and feasibility of immediate extubation (IE) versus UFTA. Methods: Sixty patients were enrolled who underwent OPCAB surgery. The two groups IE and UFTA had thirty patients each. Inclusion criteria were patients for OPCAB surgery including left main stenosis...

During the late 1950s and most of the 1960s, Dr John Ross and I led the busy clinical cardiology program then existing at the Clinical Center of the National Institutes of Health. During this period, the assessment and surgical treatment of severe aortic stenosis (AS) in adults, predominantly rheumatic in origin, were both undergoing rapid changes. In the 1950s, before open heart surgery and left-sided heart catheterization were available, after thoracotomy dilators were inserted through a ventriculotomy, and severely obstructed aortic valves were "blindly" opened...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement (SAVR), but unbiased data regarding evolution of the treatment of patients with aortic stenosis at the nationwide level are scarce. OBJECTIVES: This study sought to evaluate the number of aortic valve replacements (AVRs) performed in France, changes over time, and the effect of the adoption of TAVR. METHODS: Based on a French administrative hospital-discharge database, the study collected all consecutive AVRs performed in France between 2007 and 2015...

Transcatheter aortic valve implantation (TAVI) has become the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. In this high risk patient population, early and late mortality and rehospitalization rates after TAVI are still relatively high. In spite of recent improvements in procedural TAVI, and establishment of risk models for poor outcome, determining individual risk remains challenging. In this context, current data from several small studies strongly suggest that blood biomarkers of myocardial injury, cardiac mechanical stretch, inflammation, and hemostasis imbalance might play an important role by providing informations on patient risk at baseline, and postprocedural progression of patient clinical conditions from days up to years post-TAVI...
