BACKGROUND: Transcatheter Aortic Valve Replacement (TAVR) is increasingly performed using a minimalist approach under monitored anesthesia care (MAC). The safety of this approach remains controversial and adoption has been low in the US. METHODS: The study cohort was comprised of 130 patients (98% male) who underwent TAVR between 4/2015 and 4/2017 at the Minneapolis VA. We compared the outcomes of 81 patients who underwent TAVR using a standard approach (standard TAVR) and 49 who underwent TAVR using a minimalist approach (minimalist TAVR)...

BACKGROUND: Thromboembolic events are infrequent but serious complications of transcatheter aortic valve implantation (TAVI), occurring in 2.3-10% of the patients. However, the cause of post-TAVI stroke is unclear. CASE DESCRIPTION: A 90-year-old female underwent transfemoral-TAVI for severe aortic stenosis. Ten days later, she presented with an ischemic stroke of the left middle cerebral artery territory due to new-onset atrial fibrillation (NOAF). She underwent emergent endovascular thrombectomy with good reperfusion approximately 6 hours after onset of symptoms...

BACKGROUND: The interval between the onset of cerebral vessel occlusion and recanalization has been shown to be an independent predictor of poor outcomes. However, endovascular recanalization of symptomatic cerebral vessel occlusion in the subacute period has not been well documented. We investigated the safety and efficacy of subacute recanalization of occluded cerebral vessels in patients with ischemic stroke or transient ischemic attacks (TIAs). METHODS: Between 2014 and 2015, 98 patients were admitted to the emergency room for ischemic stroke or TIA with a small infarct core, which was defined as modest early ischemic change on non-contrast CT or overt diffusion-perfusion mismatch...

A 59-year-old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre-stenting...

In the United States, valvular heart disease (VHD) has a prevalence of 2.5%, most commonly presenting as aortic stenosis (AS) or mitral valve regurgitation (MR) and increasingly observed to be of a degenerative etiology. Women frequently have latent symptoms despite significant disease, and it is therefore pertinent to consider both clinical symptoms and imaging findings for decision-making on treatment. Indeed, significant advances have been made in noninvasive imaging allowing for more accurate diagnosis and disease prognostication...

Respiratory complications are a major factor contributing to postoperative morbidity and mortality, especially in patients with chronic obstructive pulmonary disease (COPD). Our objective was to compare the rate of respiratory complications in patients with COPD with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR). Low-to-intermediate surgical-risk patients with moderate or severe COPD who underwent TAVI or SAVR at 2 tertiary centers were included in this study...

BACKGROUND: Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety...

Algorithms for locomotion mode recognition (LMR) based on surface electromyography and mechanical sensors have recently been developed and could be used for the neural control of powered prosthetic legs. However, the variations in input signals, caused by physical changes at the sensor interface and human physiological changes, may threaten the reliability of these algorithms. This study aimed to investigate the effectiveness of applying adaptive pattern classifiers for LMR. Three adaptive classifiers, i.e...

Background -Conscious sedation is used during transcatheter aortic valve replacement (TAVR) with limited evidence as to the safety and efficacy of this practice. Methods -The NCDR STS/ACC TVT Registry was used to characterize the anesthesia choice and clinical outcomes of all U.S. patients undergoing elective percutaneous transfemoral TAVR between April 1, 2014 and June 30, 2015. Raw and inverse probability of treatment weighted (IPTW) analyses were performed to compare general anesthesia patients with conscious sedation patients on an intention-to-treat basis for the primary outcome of in-hospital mortality, and secondary outcomes including 30-day mortality, in-hospital and 30-day death/stroke, procedural success, ICU and hospital length-of-stay, and rates of discharge to home...

Cardiac computed tomography (CT) provides additional information with ultrasound in the transcatheter heart valve (THV) size selection. However, the influence of these incremental data on outcomes has not been evaluated in a randomized study. A single-center prospective, randomized, and open study was performed. Patients referred for transfemoral transcatheter aortic valve implantation with a balloon-expandable endoprothesis were included. THV size selection was performed using either transthoracic and transesophageal echocardiography data (control group) or ultrasound and CT results (CT group)...
