An interactive, online decision aid assessing patient goals and preferences for treatment of aortic stenosis to support physician-led shared decision-making: Early feasibility pilot study.

Background: Guidelines recommend shared decision making when choosing treatment for severe aortic stenosis but implementation has lagged. We assessed the feasibility and impact of a novel decision aid for severe aortic stenosis at point-of-care.

Methods: This prospective multi-site pilot cohort study included adults with severe aortic stenosis and their clinicians.

Treatment of Severe Symptomatic Aortic Stenosis During Pregnancy: A Potential Role for TAVR?

A 35-year-old woman presented at 22 weeks gestation with severe symptomatic aortic stenosis with a mean gradient of 94 mm Hg and an aortic valve area of 0.53 cm. After multidisciplinary discussion, she underwent transcatheter aortic valve replacement during pregnancy.

3-Year Outcomes After Transcatheter or Surgical Aortic Valve Replacement in Low-Risk Patients With Aortic Stenosis.

Background: Randomized data comparing outcomes of transcatheter aortic valve replacement (TAVR) with surgery in low-surgical risk patients at time points beyond 2 years is limited. This presents an unknown for physicians striving to educate patients as part of a shared decision-making process.

Objectives: The authors evaluated 3-year clinical and echocardiographic outcomes from the Evolut Low Risk trial.

Association of Transcatheter Aortic Valve Replacement Reimbursement, New Technology Add-on Payment, and Procedure Volumes With Embolic Protection Device Use.

Importance: In the setting of uncertain efficacy and additional, unreimbursed cost, use of an embolic protection device (EPD) during transcatheter aortic valve replacement (TAVR) has had variable uptake. The Centers for Medicare & Medicaid Services (CMS) instituted a new technology add-on payment to cover EPD use in October 2018.

Objective: To evaluate the association between CMS TAVR reimbursement rates and EPD use.

What matters most to patients with severe aortic stenosis when choosing treatment? Framing the conversation for shared decision making.

Background: Guidelines recommend including the patient's values and preferences when choosing treatment for severe aortic stenosis (sAS). However, little is known about what matters most to patients as they develop treatment preferences. Our objective was to identify, prioritize, and organize patient-reported goals and features of treatment for sAS.

Adjunctive Techniques for Repair of Ischaemic Mitral Regurgitation.

Ischaemic mitral regurgitation is a complex process with debate in the literature as to the optimal treatment pathway. Multiple therapies are available to alleviate mitral regurgitation including medical management, transcatheter edge-to-edge repair, mitral valve repair and mitral valve replacement. Medical management with goal-directed therapy should be utilised in patients with heart failure and mild-to-moderate regurgitation.

Alterations in Intracardiac Flow Patterns Affect Mitral Leaflets Dynamics in a Model of Ischemic Mitral Regurgitation.

Purpose: This study was to evaluate the effects of ischemic mitral regurgitation (IMR) on vortex formation and leaflet dynamics using an established porcine infarct model of IMR.

Methods: Using direct coronary ligation, five animals were subjected to a posterolateral myocardial infarction (MI) followed by an MRI at 12-weeks post MI. MR imaging consisted of 4D time-resolved left ventricular (LV) flow, full coverage 2D LV cine, and high resolution 2D cine of mitral valve dynamics.

Early US experience with cardiac donation after circulatory death (DCD) using normothermic regional perfusion.

Background: Given the shortage of suitable donor hearts for cardiac transplantation and the growing interest in donation after circulatory death (DCD), our institution recently began procuring cardiac allografts from DCD donors.

Methods: Between October 2020 and March 2021, 15 patients with heart failure underwent cardiac transplantation using DCD allografts. Allografts were procured using a modified extracorporeal membrane oxygenation circuit for thoracic normothermic regional perfusion (TA-NRP) and were subsequently transported using cold static storage.

Impact of increased donor distances following adult heart allocation system changes: A single center review of 1-year outcomes.

Background: On October 18, 2018, several changes to the donor heart allocation system were enacted. We hypothesize that patients undergoing orthotopic heart transplantation (OHT) under the new allocation system will see an increase in ischemic times, rates of primary graft dysfunction, and 1-year mortality due to these changes.

Methods: In this single-center retrospective study, we reviewed the charts of all OHT patients from October 2017 through October 2019.

Multi-institutional collaborative mock oral (mICMO) examination for cardiothoracic surgery trainees: Results from the pilot experience.

Objective: The American Board of Thoracic Surgery-certifying examination is challenging for applicants. Single institutions have reported good results with a mock oral examination (MOE) for trainees. General surgery literature has demonstrated success with in-person multi-institutional MOE examinations.

Modeling the impact of delaying transcatheter aortic valve replacement for the treatment of aortic stenosis in the era of COVID-19.

Objective: The aim of this study was to model the short term and 2-year overall survival (OS) for intermediate-risk and low-risk patients with severe symptomatic aortic stenosis (AS) undergoing timely or delayed transcatheter aortic valve replacement (TAVR) during the 2019 novel coronavirus (COVID-19) pandemic.

Methods: We developed a decision analysis model to evaluate 2 treatment strategies for both low-risk and intermediate-risk patients with AS during the COVID-19 novel coronavirus pandemic.

Results: Prompt TAVR resulted in improved 2-year OS compared with delayed intervention for intermediate-risk patients (0.

Intraoperative venous congestion and acute kidney injury in cardiac surgery: an observational cohort study.

Background: Increased intravascular volume has been associated with protection from acute kidney injury (AKI), but in patients with congestive heart failure, venous congestion is associated with increased AKI. We tested the hypothesis that intraoperative venous congestion is associated with AKI after cardiac surgery.

Methods: In patients enrolled in the Statin AKI Cardiac Surgery trial, venous congestion was quantified as the area under the curve (AUC) of central venous pressure (CVP) >12, 16, or 20 mm Hg during surgery (mm Hg min).

Adjunctive endovascular balloon fracture fenestration for chronic aortic dissection.

Objective: Positive remodeling after thoracic endovascular aortic repair (TEVAR) for chronic thoracic aortic dissection is variable due to incomplete distal seal and retrograde false lumen perfusion. We assessed the outcomes of adjunctive balloon fracture fenestration (BFF) during TEVAR in patients with chronic aortic dissection complicated by negative remodeling.

Methods: From June 2013 to January 2016, 49 patients with chronic aortic dissection complicated by aneurysm due to negative remodeling underwent TEVAR with BFF.

Preparing for Bundled Payments: Impact of Complications Post-Coronary Artery Bypass Grafting on Costs.

Background: Bundled payments for coronary artery bypass grafting (CABG) provide a single reimbursement for care provided from admission through 90 days post-discharge. We aim to explore the impact of complications on total institutional costs, as well as the drivers of high costs for index hospitalization.

Methods: We linked clinical and internal cost data for patients undergoing CABG from 2014 to 2017 at a single institution.

Clinical Implications of Physical Function and Resilience in Patients Undergoing Transcatheter Aortic Valve Replacement.

Background Gait speed is a reliable measure of physical function and frailty in patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Slow gait speed pre-TAVR predicts worse clinical outcomes post-TAVR. The consequences of improved versus worsened physical function post-TAVR are unknown.

Quantitative three-dimensional echocardiographic analysis of the bicuspid aortic valve and aortic root: A single modality approach.

Background: Patients with bicuspid aortic valves (BAV) are heterogeneous with regard to patterns of root remodeling and valvular dysfunction. Two-dimensional echocardiography is the standard surveillance modality for patients with aortic valve dysfunction. However, ancillary computed tomography or magnetic resonance imaging is often necessary to characterize associated patterns of aortic root pathology.

Prevalence of and Risk Factors for Permanent Pacemaker Implantation After Aortic Valve Replacement.

Background: Damage to the cardiac conduction system requiring permanent pacemaker implantation is a complication of aortic valve replacement (AVR) that may importantly affect quality of life. We investigated the prevalence of and preprocedure risk factors for new permanent pacemakers after surgical (SAVR) and transcatheter AVR (TAVR) at a single institution.

Methods: Preoperative variables and baseline electrocardiograms were reviewed for 5807 patients undergoing elective SAVR, with or without coronary artery bypass grafting, and 1292 undergoing TAVR, with or without percutaneous coronary intervention, from 2006 to 2017 at Cleveland Clinic.

Perforation of a mesenteric Meckel's diverticulum.

Meckel's diverticulum is a remnant of the embryologic omphalomeseteric duct and is a common congenital anomaly found in ~2% of the population. The clinical significance of this anomaly is that the persistent diverticulum can lead to intestinal obstruction or diverticulitis and may contain ectopic tissue which can lead to bleeding, ulceration or perforation. The classic location of a Meckel's diverticulum has been described ~40 cm from the ileocecal valve on the antimesenteric side of the distal ileum.

Outcomes of a Less-Invasive Approach for Proximal Aortic Operations.

Background: Less-invasive techniques have previously been described for mitral and aortic valve operations; however, few studies have examined their benefit for aortic root and ascending aorta reconstruction. Using propensity matching, we compared outcomes of patients undergoing proximal aortic operations through a J incision compared with full sternotomy.

Methods: From January 1995 to January 2014, 8,533 patients underwent proximal aortic operations at Cleveland Clinic.

The value of preoperative 3-dimensional over 2-dimensional valve analysis in predicting recurrent ischemic mitral regurgitation after mitral annuloplasty.

Objectives: Repair for ischemic mitral regurgitation with undersized annuloplasty is characterized by high recurrence rates. We sought to determine the value of pre-repair 3-dimensional echocardiography over 2-dimensional echocardiography in predicting recurrence at 6 months.

Methods: Intraoperative transesophageal 2-dimensional echocardiography and 3-dimensional echocardiography were performed in 50 patients undergoing undersized annuloplasty for ischemic mitral regurgitation.

Preoperative Three-Dimensional Valve Analysis Predicts Recurrent Ischemic Mitral Regurgitation After Mitral Annuloplasty.

Background: Valve repair for ischemic mitral regurgitation (IMR) with undersized annuloplasty rings is characterized by high IMR recurrence rates. Patient-specific preoperative imaging-based risk stratification for recurrent IMR would optimize results. We sought to determine if prerepair three-dimensional (3D) echocardiography combined with a novel valve-modeling algorithm would be predictive of IMR recurrence 6 months after repair.
