REVIEW
Ibrahim Sultan, Mary Siki, Tyler Wallen, Wilson Szeto, Prashanth Vallabhajosyula
Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

OBJECTIVES: The authors sought to compare the outcomes of commercial transcatheter aortic valve replacement (TAVR) with the repositionable Evolut R platform to those observed with the CoreValve device in the Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) Transcatheter Valve Therapy (TVT) Registry. BACKGROUND: TAVR continues to evolve, with rapid adoption of iterative changes for commercial practice. Insight into the outcomes of this adoption is needed...

Aims: In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities. We sought to evaluate the prognostic impact of a newly-defined staging classification characterizing the extent of extravalvular (extra-aortic valve) cardiac damage among patients with severe AS undergoing AVR. Methods and results: Patients with severe AS from the PARTNER 2 trials were pooled and classified according to the presence or absence of cardiac damage as detected by echocardiography prior to AVR: no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4)...

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...

BACKGROUND AND AIM: Concomitant endovascular stent grafting of the descending thoracic aorta during open repair for acute DeBakey I aortic dissection can be performed in patients with extensive dissection and malperfusion. We analyzed the effects of this strategy on distal aortic remodeling. METHODS: From 2006-2014, acute DeBakey I dissection patients without primary aortic arch tear undergoing open distal hemiarch reconstruction (Standard group) versus those undergoing hemiarch with descending thoracic aorta (DTA) thoracic endovascular aortic repair (TEVAR group) were retrospectively reviewed...

OBJECTIVE: To compare the cost of and payments for transcatheter aortic valve replacement (TAVR), a novel and expensive technology, and surgical aortic valve replacement (SAVR). METHODS: Medicare claims provided hospital charges, payments, and outcomes between January and December 2012. Hospital costs and charges were estimated using hospital-specific cost-to-charge ratios. Costs and payments were examined in propensity score- matched TAVR and SAVR patients. RESULTS: Medicare spent $215,770,200 nationally on 4083 patients who underwent TAVR in 2012...

OBJECTIVE: To comprehensively evaluate and compare utilization, outcomes, and especially costs of transfemoral (TF), transapical (TA), and transaortic (TAO) transcatheter aortic valve replacement (TAVR). METHODS: All Medicare fee-for-service patients undergoing TF (n = 4065), TA (n = 691), or TAO (n = 274) TAVR between January 1, 2011, and November 30, 2012, were identified using Health Care Procedure Classification Codes present on Medicare claims. Hospital charges from Medicare claims were converted to costs using hospital-specific Medicare cost-to-charge ratios...

BACKGROUND: This study evaluated outcomes of elective aortic hemiarch reconstruction for aneurysmal disease in the elderly. METHODS: Patients undergoing elective aortic hemiarch reconstruction for aneurysmal disease at a single institution between 2009 and 2014 were retrospectively reviewed. Patients were stratified into nonelderly (aged less than 75 years) versus elderly (aged 75 years or more). Outcomes included operative mortality and morbidity. RESULTS: In all, 629 patients (95 elderly; 15%) were included...

OBJECTIVE: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology. METHODS: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement...

OBJECTIVE: To report the initial and midterm results of the Bolton Relay Thoracic Stent Graft for the endovascular treatment of thoracic aortic lesions [thoracic endovascular aortic repair (TEVAR)]. METHODS: The Bolton Relay Thoracic Aortic Endovascular Pivotal Trial was a prospective, nonrandomized, multicenter, U.S. Investigational Device Exemption study conducted at 27 U.S. investigational sites. One hundred twenty TEVAR subjects were treated with the Relay device between January 2007 and May 2010, with 13 patients enrolled during the continued access phase through September 2012...

Howard C Herrmann, Wilson Y Szeto, Harold Litt, William Vernick
Left ventricular outflow tract (LVOT) obstruction is a recognized complication of transcatheter mitral valve-in-valve replacement in previous surgical prostheses. We describe a patient who was high risk for repeat open surgery in whom the LVOT was compromised by a surgical strut and the potential for LVOT obstruction. A novel approach to avoiding this complication was utilized. A perfusion balloon was inflated in the outflow tract to provide an opposing force during mitral valve deployment resulting in less flaring of the strut into the outflow tract thereby improving the neo-LVOT area...

Aims: Limited data exist on the long-term outcome of patients (pts) with non-ischemic cardiomyopathy (NICM) and ventricular tachycardia (VT) refractory to conventional therapies undergoing surgical ablation (SA). We aimed to investigate the long-term survival and VT recurrence in NICM pts with VT refractory to radiofrequency catheter ablation (RFCA) who underwent SA. Methods and results: Consecutive pts with NICM and VT refractory to RFCA who underwent SA were included...

An 87-year-old woman with severe aortic stenosis underwent a transfemoral transcatheter aortic valve replacement (TAVR). Intraoperative transesophageal echocardiography demonstrated a well-seated valve with no paravalvular leak; however, a new acute type B aortic dissection was identified. Endografts were delivered through the TAVR sheath and deployed, effectively treating the dissection. The patient did well postoperatively, with imaging at 2 years demonstrating a well-functioning aortic valve and no migration or endoleak of the thoracic endografts...

OBJECTIVES: The aim of this study was to evaluate the long-term performance of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) through longitudinal echocardiographic analysis. BACKGROUND: The long-term performance of the SAPIEN TAVR is not well-described. Therefore, we examined the hemodynamic and valvular profile of the SAPIEN TAVR over 5 years. METHODS: All patients receiving TAVR or SAVR with first post-implant (FPI) and 5-year echoes were analyzed for aortic valve (AV) peak velocity, AV mean gradient, AV area, peak left ventricular (LV) outflow tract and in-stent velocities, Doppler velocity index, aortic regurgitation (AR), LV mass index, stroke volume index, and cardiac index...
