Women in Thoracic Surgery 2020 Update-Subspecialty and Work-Life Balance Analysis.

BACKGROUND: While women comprise nearly half of medical school graduates, they remain underrepresented in cardiothoracic (CT) surgery. To better understand ongoing barriers, we aimed to delineate issues relevant to the CT subspecialities, emphasizing personal life. METHODS: An anonymous Research Electronic Data Capture (REDCap; hosted at Indiana University School of Medicine) survey link was emailed to female diplomats of the American Board of Thoracic Surgeons (ABTS). The survey included questions on demographics, professional accolades, practice details, and personal life. Survey responses were compared across subspecialities using χ2 testing. RESULTS: Of 354 female ABTS diplomats, we contacted 309, and 176 (57%) completed the survey. By subspecialty, 42% practice thoracic, 26% adult cardiac, and 10% congenital cardiac; 19% report a mixed practice. The subspecialties differed in length of training (congenital-the longest), practice location (mixed practice-less urban), and academic rank (thoracic-most full professors at 17%), but were largely similar in their personal lives. Among all respondents, 65% are in a committed relationship, but 40% felt that being a CT surgeon negatively impacted their ability to find a partner. Sixty percent have children, but 31% of those with children reported using assisted reproductive technology, surrogacy, or adoption. The number with leadership roles (eg, division chief, committee chair of national organization) did not differ among subspecialities, but was low, ranging from 0 to <30%. CONCLUSIONS: Women remain underrepresented in CT surgery, particularly in the academic rank of full professor and in leadership positions. We advocate for scholarship and mentorship opportunities to encourage women to enter the field, increased female leadership, and policies to enable families.

Epstein-Barr Virus Predicts Malignancy After Pediatric Heart Transplant, Induction Therapy and Tacrolimus Don't.

BACKGROUND: Patients after heart transplantation are at increased risk for malignancy secondary to immunosuppression and oncogenic viral infections. Most common among children is posttransplant lymphoproliferative disorder (PTLD), occurring in 5% to 10% of patients. We used a national database to examine the incidence and risk factors for posttransplant malignancy. METHODS: The United Network for Organ Sharing database was queried for pediatric (<18 years) heart transplant recipients from October 1987 through November 2019. Freedom from malignancy after transplant was assessed with Kaplan-Meier analysis. Cox regression was performed to generate hazard ratios (HRs) and 95% CIs for risk of malignancy development. RESULTS: Of 8581 pediatric heart transplant recipients, malignancy developed in 8.1% over median follow-up time of 6.3 years, with PTLD compromising 86.4% of the diagnosed cancers. The incidence of PTLD development was 1.3% at 1 year and 4.5% at 5 years. Older age at the time of transplant was protective against the development of malignancy (HR, 0.98; 95% CI, 0.96-0.99; P < .001), whereas a history of previous malignancy (HR, 1.9; 95% CI, 1.2-3.0; P = .007) and Ebstein-Barr virus (EBV) recipient-donor mismatch (HR, 1.7; 95% CI, 1.3-2.2; P < .001) increased the risk. Induction therapy, used in 78.9% of the cohort, did not increase malignancy risk (P = .355) nor did use of maintenance tacrolimus (P = .912). CONCLUSIONS: PTLD occurred after 7% of pediatric heart transplants, with risk increased by younger age and EBV mismatch, highlighting the importance of PTLD monitoring in EBV-seronegative recipients. Induction therapy, used in most of the pediatric heart transplants, does not seem to increase posttransplant malignancy nor does tacrolimus, the most commonly used calcineurin inhibitor.

Aiming to Preserve Pulmonary Valve Function in Tetralogy of Fallot Repair: Comparing a New Approach to Traditional Management.

Pulmonary valve (PV) incompetence following transannular patch (TAP) repair of tetralogy of Fallot (TOF) results in long-term morbidity and mortality. Valve-sparing repairs have recently gained recognition; however, they may be associated with residual pulmonary stenosis (PS) in patients with small PV z scores. We sought to determine whether a repair that increases the PV annulus and augments the valve leaflet with a biomaterial would result in annular growth and in longer duration of valve competence compared with TAP. Eighty patients (median age 136 days, range 4-350) who underwent surgical repair of TOF between 2010 and 2014 were included in the study. Patients were divided into three groups based on the PV intervention: balloon dilation/valvotomy (n = 29), valve-sparing transannular repair (VSTAR) (n = 19) and TAP (n = 32). Intraoperative, early postoperative and midterm follow-up echocardiographic data (median 19 months, range 1-59) were obtained. The primary outcomes were the presence and severity of pulmonary regurgitation and/or PS. Compared with TAP, VSTAR patients demonstrated significantly less severe PR with 100 % freedom of severe PR immediately post-op (vs. 0 % in TAP), 60 % at 6 months and 20 % at 20 months. There were no differences in PS between VSTAR and TAP at follow-up. A subgroup analysis of the VSTAR group was performed. PV z scores were calculated and fit to a random effects model. Patient data fit the model closely, predicting a reproducible increase in valve annulus size over time. With better short-term and comparable midterm results, VSTAR may be appropriate for TOF repair in patients with small PV that would conventionally require a TAP.
