Selective Sinus Replacement for Aortic Root Aneurysm: Durable Approach in Selected Patients.

Background: Selective sinus replacement (SSR) allows a tailored repair approach in patients with sinus of Valsalva or asymmetric aortic root aneurysm. SSR avoids the need for coronary reimplantation for nondiseased sinuses and shortens operative time, although potential for late growth of retained sinuses exists. This study describes selection of patients and assesses operative outcomes and late root dimensions after SSR.

Tailored approach and outcomes of aortic arch reconstruction after acute type A dissection repair.

Objective: After limited root/ascending with or without hemiarch repair for acute type A aortic dissection (ATAAD), 20% to 30% of patients require distal reintervention, frequently for arch pathology. In this report, we describe an institutional algorithm for arch management after previous limited ATAAD repair and detail operative and long-term outcomes.

Methods: From August 2005 to April 2021, 71 patients status post previous limited ATAAD repair underwent reoperative arch repair involving zones 1 to 3 for aneurysmal degeneration of residual arch dissection including complete cervical debranching with zone 0/1 thoracic endovascular aortic repair in 6 (8%), open total arch in 13 (18%), type I hybrid arch repair in 23 (32%), and type II/III hybrid arch repair in 29 (41%).

Stent Graft-induced Aortic Wall Injury: Incidence, Risk Factors, and Outcomes.

Background: Stent graft-induced new entry has been described in thoracic endovascular aortic repair for aortic dissection. The incidence of stent graft-induced aortic wall injury (SAWI) related to iatrogenic injury in nondissections is incompletely described. We describe incidence, risk factors, and outcomes of SAWI.

Long-term outcomes of aortic root replacement for endocarditis.

Background: Infective endocarditis (IE) involving the aortic valve and root is associated with high risk requiring thoughtful surgical decision-making. The impact of valve and conduit choices and patient factors on long-term outcomes in this patient population is poorly documented.

Methods: From January 1976 to December 2013, 485 patients underwent aortic root and valve replacement at a single institution.

Coronary Anastomosis Simulation: Directed Interventions to Optimize Success.

Background: The role of simulation-based training in coronary artery bypass grafting remains undefined. Barriers to simulator use include clinical and personal obligations, insufficient materials, and lack of mentorship. The purpose of this study was to implement a longitudinal, residency-wide coronary anastomosis simulation curriculum.

Emerging trends in mediastinitis: National Veterans Health Administration experience with methicillin-resistant Staphylococcus aureus prevention.

Objectives: Perioperative bacterial decolonization and prophylactic antibiotic therapy at the Veterans Affairs Health Care System have changed over the past decade. Our objectives were to identify associated changes in the microbiology of mediastinitis and to perform a contemporary survival analysis in patients with mediastinitis after isolated coronary artery bypass grafting procedure.

Methods: From January 2006 to December 2015, 45,323 consecutive patients underwent coronary artery bypass grafting at 83 medical centers.

Early outcomes with durable left ventricular assist device replacement using the HeartMate 3.

Background: The HeartMate 3 (HM3) left ventricular assist device (LVAD) (Abbott, Inc, Chicago, Ill) is a fully magnetically levitated centrifugal implantable pump used to treat patients with chronic heart failure. The MOMENTUM (Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3) trial demonstrated that patients treated with the HM3 experienced reduced need for reoperation for LVAD replacement compared with a control group receiving an axial flow design, Heartmate II (Abbott, Inc). However, there are few reports of using HM3 as the replacement pump in patients who already are supported by a durable LVAD and experience a device-related complication necessitating replacement.

Minimally Invasive Pulmonary Fibroelastoma Resection.

Pulmonary fibroelastomas are a rare primary cardiac tumor with less than 50 cases reported in the literature to date. We performed a minimally invasive valve-sparing tumor resection through a left anterior mini-incision (LAMI). The procedure was performed without cardiac arrest or aortic cross clamp, expediting postoperative recovery and allowing for an uncomplicated discharge on postoperative day 5.

Constrictive Pericarditis After Lung Transplantation.

Background: Constrictive pericarditis is a rare, but increasingly recognized long-term postoperative complication of lung transplantation. Heightened clinical suspicion, improved diagnostic imaging, and effective surgical treatment of the disease have led to progressive awareness of the pathology. We present our institutional experience with constrictive pericarditis after lung transplant in an effort to investigate the cause and natural history of the disease.

A Model for a Formal Mentorship Program in Surgical Residency.

Background: Mentorship is a key component in preventing burnout and attrition in surgical training, yet many residencies lack a formal program, one method used to establish successful mentor relationships. We aimed to measure the difference in resident perceptions and experience after the implementation of a mentorship program.

Methods: An anonymous survey was distributed to all general surgery residents at a single academic institution before and after implementation of a year-long mentorship program that involved assigned mentors, two social events, and recommended mentorship meetings.
