BACKGROUND: Early experience with leadless pacemakers has shown a low rate of complications. However, little is known about system revision in patients with these devices. OBJECTIVE: To describe the system revision experience with the Micra Transcatheter Pacing System (TPS). METHODS: Implanted patients from the Micra TPS and the Micra Continued Access study (N = 989) were analyzed and compared to 2667 patients with transvenous pacemakers (TVP)...

OBJECTIVE: Conduction disturbances are common in patients with aortic stenosis. We investigated the incidence, reversibility, and prognosis of conduction disorders requiring permanent pacemaker implantation in patients with degenerative aortic stenosis after isolated aortic valve replacement. METHODS: This was a retrospective study conducted at a tertiary care center. We evaluated the incidence of conduction disturbances in patients who underwent isolated surgical aortic valve replacement for aortic stenosis between January 2005 and May 2015...

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...

BACKGROUND: The del Nido cardioplegia (DC) procedure offers prolonged cardiac protection with single-dose administration and has proven safe in adult coronary artery bypass grafting (CABG) surgery. We set out to evaluate the efficacy of cardiac protection and clinical outcomes of DC versus standard blood cardioplegia (BC) in minimally invasive aortic valve surgery. METHODS: Between August 2011 and May 2016, 178 patients underwent minimally invasive aortic valve replacement (AVR) with BC (n = 101) or DC (n = 77)...

OBJECTIVES: To evaluate aortic velocity, wall shear stress (WSS) and viscous energy loss (EL) of stented and stentless bioprostheses using 4D flow MRI 1 year after surgical aortic valve replacement. METHODS: For this cross-sectional study 28 patients with stented (n = 14) or stentless (n = 14) bioprosthesis underwent non-contrast-enhanced 4D-flow MRI at 1.5 T. Analyses included a comparison of velocity, WSS and EL in the ascending aorta during peak systole for both spatially averaged values and a comparison of local differences using per-voxel analysis...

REVIEW
Andrei D Mǎrgulescu
Aortic valve disease [aortic stenosis (AS) and aortic regurgitation (AR)] represents an important global health problem; when severe, aortic valve disease carries poor prognosis. For AS, aortic valve replacement, either surgical or interventional, may provide definite treatment in carefully selected patients. For AR, valve surgery (either replacement or - in selected cases - aortic valve repair) remains the gold standard of care. To properly identify those patients who are candidates for surgery, the clinician has to carefully assess the severity of valve disease with an understanding of the potential pitfalls involved in these assessments...

Aortic root abscess is a complication of aortic valve endocarditis that is associated with a high morbidity and mortality. The diagnosis usually is made with transesophageal echocardiography, which is highly sensitive and specific for the disease. We present a case of suspected aortic root abscess 1 week after mechanical aortic valve replacement for native valve endocarditis. The diagnosis was made by the use of transesophageal echocardiography but surgical inspection revealed that the paravalvular fluid collection was excessive surgical adhesive...

Trifecta valve is a 3rd-generation, stented bioprosthesis which is made from one bovine pericardial sheet. A 77-years-old male patient had undergone combine aortic valve replacement (AVR) using a 23-mm Trifecta valve and ascending aorta replacement for severe aortic valve regurgitation and ascending aorta aneurysm. The postoperative period was uneventful. However, he presented with dyspnea on effort and severe aortic valve regurgitation 31 months after operation. Re-do AVR with a new bioprosthetic valve was performed via 2nd sternotomy...

BACKGROUND: Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) may be less effective in small surgical valves because of patient/prosthesis mismatch. Bioprosthetic valve fracture (BVF) using a high-pressure balloon can be performed to facilitate VIV TAVR. METHODS AND RESULTS: We report data from 20 consecutive clinical cases in which BVF was successfully performed before or after VIV TAVR by inflation of a high-pressure balloon positioned across the valve ring during rapid ventricular pacing...

BACKGROUND: Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects. METHODS: AOx during SAVR was divided into five consecutive steps...

BACKGROUND: Frailty is a geriatric syndrome that diminishes the potential for functional recovery after a transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) procedure; however, its integration in clinical practice has been limited by a lack of consensus on how to measure it. OBJECTIVES: This study sought to compare the incremental predictive value of 7 different frailty scales to predict poor outcomes following TAVR or SAVR...

Cirrhosis is known to adversely affect cardiac surgery outcomes. Our objective was to quantify the morbidity, mortality, and cost that cirrhosis adds to surgical aortic valve replacement. From 1998 to 2011, 423,789 patients in the Nationwide Inpatient Sample Healthcare Cost Utilization Project underwent isolated aortic valve replacement; 2,769 (0.7%) had cirrhosis. Multivariable linear regression and 1:1 propensity matching were used to determine the effect of cirrhosis on postsurgical outcomes. The number of patients with cirrhosis who underwent surgical aortic valve replacement per year more than tripled during the 13-year study period...

BACKGROUND: Patients undergoing surgical aortic valve replacement (sAVR) have high rates of 30-day readmissions. They also report a low health-related quality of life (HRQOL) and elevated anxiety and depression. The aim of the AVRre study is to determine the efficacy and cost of a 24/7 phone-support intervention in reducing post-discharge readmissions after sAVR. The nature of the support is to help patients better understand and self-manage non-urgent symptoms at home. METHODS/DESIGN: AVRre is a prospective, randomised controlled study comprising 30 days of continuous phone-support intervention and then intermittent follow-up for the first 12 months...

BACKGROUND: This study presents data on post-discharge costs of care among patients treated with transcatheter or surgical aortic valve replacement over a two year period. METHODS: Based on a prospective clinical trial, post-discharge utilization of health services and status of assistance were collected for 151 elderly patients via 2250 monthly telephone interviews, valued using standardized unit costs and analysed using two-part regression models. RESULTS: At month 1 post-discharge, total costs of care are substantially elevated (monthly mean: €3506...

AIMS: Patients with degraded bioprosthetic heart valves (BHV) who are not candidates for valve replacement may benefit from transcatheter valve-in-valve (VIV) therapy. However, at smaller sized surgical BHV the resultant orifice may become too narrow. To overcome this, the valve frame can be fractured by a high-pressure balloon prior to VIV. However, knowledge on fracture pressures and mechanics are prerequisites. The aim of this study is to identify the fracture pressures needed in BHV, and to describe the fracture mechanics...

OBJECTIVES: Vascular complications remain a significant technical challenge for transfemoral TAVR (Transcatheter Aortic Valve Replacement). The goal of this study was to develop a pre-operative tool for prediction of major vascular complications of TAVR. METHODS: A retrospective review was performed of all patients who underwent transfemoral TAVR at a tertiary medical center from 2011-2015. Iliofemoral arterial measurements were obtained with CTA 3D reconstructions images and an Iliac Morphology Score (IMS) was created from these measurements...
