Aims: In patients with severe aortic stenosis (AS) and preserved left ventricular ejection fraction (LVEF), low flow (LF) is currently defined using Doppler-echocardiography by a stroke volume index (SVi)<35 mL/m2. However, the relationship between LF and outcome remains unclear as data on normal reference values defining LF are scarce, and previous studies did not explore the risk associated with other SVi cut-points. We analysed the relationship between LF and mortality in severe AS to establish prognostic LF values associated with mortality risk...

BACKGROUND: This study sought to analyze in-hospital outcomes associated with pre-existing and newly implanted Permanent Pacemaker (PPM) in patients who underwent Transcatheter Aortic Valvular Replacement (TAVR). PPM implantation following the development of conduction abnormalities is a common adverse event following TAVR. Furthermore, PPM implantation rates are higher in TAVR patients compared to the surgical alternative, thus we have analyzed the predictors of pacing post-TAVR. METHODS: The study population was identified from the National Inpatient Sample Database between 2012 and 2014...

BACKGROUND : Comparative echocardiographic data on transcatheter aortic valve replacement systems from randomized trials are limited. The REPRISE III trial (Repositionable Percutaneous Replacement of Stenotic Aortic Valve through Implantation of Lotus Valve System - Randomized Clinical Evaluation) is a multicenter, randomized comparison of a mechanically expanded (Lotus) versus self-expanding (CoreValve) transcatheter aortic valve replacement device. This analysis rigorously assesses Doppler-derived valve hemodynamics and the impact on outcomes at 1 year in patients with extreme/high surgical risk treated with Lotus and CoreValve from REPRISE III...

BACKGROUND: Frailty is an important predictor of outcomes after cardiac surgery, but utility is limited by difficult assessment and quantification. We hypothesize that sarcopenia defined as psoas muscle cross-sectional area is a useful predictor of surgical aortic valve replacement (SAVR) outcomes in moderate to high-risk patients. METHODS: Moderate to high-risk (predicted risk of mortality [PROM] >3%) patients who underwent SAVR with or without coronary bypass were extracted from an institutional database (2009-2016)...

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare cardiac anomaly associated with sudden cardiac death (SCD). Single-center studies describe surgical repair as safe, although medium- and long-term effects on symptoms and risk of SCD remain unknown. We sought to describe outcomes of surgical repair of AAOCA. METHODS: We reviewed institutional records for patients who underwent AAOCA repair, from 2001 to 2016, at 2 affiliated institutions...

Major vascular complications still occur in ~4.2% of transcatheter aortic valve replacement (TAVR) procedures. These complications are a major safety drawback of TAVR when compared to surgical aortic valve replacement (SAVR). Contemporary strategies designed to minimize and effectively treat vascular complications are of immense importance to a successful TAVR program. This review discusses strategies to optimize TAVR access and device choice along with TAVR access complication management. Iliac complications are less frequently encountered and can be managed effectively via the TAVR sheath over the TAVR wire employing ipsilateral proximal iliac balloon occlusion and endovascular repair...

Postoperative bleeding with its important socioeconomic cost is associated with an increased morbidity and mortality. It causes hemodynamic instability, increases blood loss, and multiplies the number of transfusions required. Especially in vascular or aortic surgery, postoperative bleeding can become a life-threatening complication due to anticoagulant or antiaggregation preoperative status or postoperative coagulation dysfunction after a high level of heparinization. Presently described is the case of a patient who underwent an aortic valve and ascending aorta replacement...

PURPOSE OF REVIEW: This review will summarize the growing importance of diagnosing and managing paravalvular leak associated with surgical and transcatheter valves. RECENT FINDINGS: The burden of paravalvular leak is increasing; however, advanced imaging techniques and high degree of clinical suspicion are required for diagnosis and management. The latest data from pivotal clinical trials in the field of transcatheter aortic valve replacement suggest that any paravalvular leak greater than mild was associated with worse clinical outcomes...

Background: Time-driven activity-based costing (TDABC) is a methodology that calculates the costs of healthcare resources consumed as a patient moves along a care process. Limited data exist on the application of TDABC from the perspective of an anesthesia provider. We describe the use of TDABC, a bottom-up costing strategy and financial outcomes for three different medical-surgical procedures. Methods: In each case, a multi-disciplinary team created process maps describing the care delivery cycle for a patient encounter using the TDABC methodology...

OBJECTIVES: Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. METHODS: Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively...

BACKGROUND: Minimally invasive aortic valve replacement (mAVR) is gaining clinical acceptance, however, it is associated with increased operative times due to limited surgical field and access. The Cor-Knot is an automated fastening device designed to facilitate suture fastening, but clinical data in mAVR are lacking. METHODS: From May 2014 to February 2017, 92 patients underwent mAVR at our center with 39 valves secured with manually-tied (MT) sutures and 53 valves entirely secured with the Cor-Knot (CK)...

Diseases of the cardiovascular system account for nearly 42% of all deaths in the European Union. In Germany, approximately 12,000 patients receive surgical replacement of the aortic valve due to heart valve disease alone each year. A three-dimensional (3D) numerical model based on patient-specific anatomy derived from four-dimensional (4D) magnetic resonance imaging (MRI) data was developed to investigate preoperatively the flow-induced impact of mounting positions of aortic prosthetic valves to select the best orientation for individual patients...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is now the treatment of choice for high-surgical risk patients with symptomatic aortic stenosis. Little is known regarding the outcome of TAVR in patients with previous malignancy. METHODS: We investigated 477 patients who underwent TAVR in a tertiary medical center. Subjects were divided into two groups according to malignancy status: no history of malignancy (n = 386) and positive history of malignancy (n = 91)...
