Practice patterns of female cardiothoracic surgeons older than age 58 years: Are we making progress?

OBJECTIVE: Women remain a small minority of cardiothoracic surgeons, and within adult cardiac surgery, the gender gap widens. This study examines the career pathway and trajectory of female adult cardiac surgeons. METHODS: Female cardiothoracic surgeons were identified from the American Board of Thoracic Surgery diplomates over 58 years. Publicly available information was obtained to determine years in practice, practice type, academic and leadership title(s), and location of practice. RESULTS: The average number of years in practice for female adult cardiac surgeons was 13.1. Those categorized as adult cardiac surgeons composed 25.4% (n = 90) of all female cardiothoracic diplomates and 134 (37.9%) were categorized as other subspecialty practice. Of the adult cardiac surgeons, 33.3% (n = 30) practiced privately and the remainder in academic practice. Academic titles were held by 47.8% (43 out of 90) and 30% (27 out of 90) held a position of leadership. Of those in academic practice, 25% (11 out of 42) are titled professor, whereas 43% (18 out of 42) are assistant professors. Most commonly, those in positions of leadership held the title "director," which reflects 37% (10 out of 27) of individuals. Practice locations were distributed throughout the United States, with the highest number in the northeast (26.7%). CONCLUSIONS: Only a small portion of female cardiothoracic surgeons pursue a career in adult cardiac surgery compared to their male counterparts. From 1999 to 2009, 1300 individuals were board certified cardiothoracic surgeons, of whom only 103 (7.9%) were female. Of these, the majority of female cardiothoracic surgeons entered academic practice. Although the overall number of practicing female adult cardiac surgeons has increased with a growth rate of 10.7%, this number remains extremely low. A discrepancy remains between gender representation of academic titles and leadership positions. Although the field has increased female representation over the past few decades, work remains to ensure all potential talent is encouraged and supported.

Unconventional use of total artificial heart in a patient with severe, destructive prosthetic valve endocarditis.

Here, we report the case of a patient who presented to our institution with severe, destructive, and unreconstructable prosthetic valve endocarditis which required the planned implantation of a total artificial heart (TAH) to function as a bridge to cardiac transplantation. The use of TAH in this fashion has been infrequently reported in the literature. This case highlights the importance of a thoughtful, preoperative multidisciplinary approach to these complex patients to provide the most appropriate and life-saving care.

Left ventricular assist device implantation by bi-thoracotomy technique: A single-center perspective.

BACKGROUND: Left ventricular assist devices (LVAD) are standardly implanted via full sternotomy. Nonsternotomy approaches are gaining popularity, but potential benefits of this approach have not been well-studied. We hypothesized that LVAD implantation by bi-thoracotomy (BT) would demonstrate smaller and more consistent inflow cannula angles leading to improved postoperative outcomes compared to sternotomy. METHODS: Charts of patients who underwent LVAD implantation between June 2018 and June 2020 at a single academic institution were retrospectively reviewed. Patient demographics, surgical approach (sternotomy vs. BT), laboratory values, and postoperative course were compared. The inflow cannula angle was measured on the first chest radiograph available postoperatively. RESULTS: Of 40 patients studied, BT approach was used in 17 (42.5%). Mean inflow cannula angles were smaller in BT patients (23.0 vs. 37.1 degrees, p = .018) and had a smaller standard deviation (13.8 vs. 20.3). Excluding patients who went on to receive a heart transplant or died in the same hospitalization, there was no difference in median length of hospital stay after surgery (16.0 vs. 17.5 days, p = .768). However, BT patients required fewer days of postoperative inotrope support (4.0 vs. 7.0 days, p = .012). CONCLUSIONS: Our data suggest inflow cannula angles are smaller and more consistent with the BT approach, which leads to a shorter duration of postoperative inotropic support. This finding may suggest improved right heart function following LVAD implant via BT approach. Further study is warranted to determine additional benefits of the BT approach.

Successful heart transplantation in a patient who recovered from COVID-19.

Coronavirus disease-2019 has created unprecedented challenges for society, and specifically the medical community. While the pandemic continues to unfold, the transplant community has had to pivot to keep recipients, donors, and institutional transplant teams safe given the unique circumstances inherent to solid organ transplantation.

The changing landscape of percutaneous technology leading to surgical complications.

With new technology comes new complications. We discuss the interesting case presented by Bjelic and colleagues regarding a misplaced TAVR (transcatheter aortic valve replacement) valve into the inflow cannula of a left ventricular assist device, leading to hemodynamic collapse. The author describes the pitfalls of the new technology and interesting surgical maneuvers to address these complications.

Intra-aortic balloon pump placement in coronary artery bypass grafting patients by day of admission.

INTRODUCTION: Intra-Aortic Balloon Pumps (IABPs) can be utilized to provide hemodynamic support in high risk patients awaiting coronary artery bypass grafting (CABG). There are many indications for IABP and institutional practice patterns regarding the placement of IABPs is variable. As a result, the preoperative placement of an IABP in a patient awaiting CABG is not standardized and may vary according to non-clinical factors. We hypothesize that the rate of IABP placement varies by day of the week. METHODS: A retrospective cohort analysis of the Office of Statewide Health Planning and Development database from 2006 to 2010 was performed. All patients admitted for CABG were included. Patients who died within 24 h of admission and those who had absolute contraindications to IABP placement were excluded. The primary outcome was preoperative IABP placement versus non-placement. A multivariable logistic regression analysis to identify predictors of IABP placement was performed, adjusting for patient demographics, clinical factors, and system variables. RESULTS: A total of 46,347 patients underwent CABG, of which 7695 (16.60%) had an IABP placed preoperatively. On unadjusted analysis, IABP rates were significantly higher on weekends versus weekdays (20.83% vs. 15.70%, p < 0.001). On adjusted analysis, patients awaiting CABG were 1.30 times more likely to have an IABP placed on weekends than on weekdays (OR: 1.30, 95% CI 1.20-1.40, p < 0.001). CONCLUSION: The odds of preoperative IABP placement prior to CABG is significantly increased on weekends compared to weekdays, even when controlling for clinical factors. Further exploration of this phenomenon and its associations are warranted.

Balancing supply and demand: Review of the 2018 donor heart allocation policy.

Heart transplant remains the most effective treatment for patients with end stage heart failure. Advances in mechanical circulatory support devices have changed the therapeutic landscape and contributed to a demographic shift in patients awaiting transplant. In the setting of a growing waitlist and concern for an inability of current policies to accurately account for patient acuity and equitable geographic distribution of organs, the United Network for Organ Sharing developed a new donor heart allocation policy which was introduced in 2018. The new policy creates more precise listing criteria to reflect patient acuity, addresses previously marginalized groups, and takes steps to address geographic inequalities.

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. Due to small numbers of cardiothoracic training programs and significant geographic variability, we hypothesized that a multi-institutional, collaborative remotely administered MOE (mICMO) pairing faculty with trainees from different institutions would provide an important educational experience. METHODS: mICMOs were conducted via the Zoom virtual platform across 6 institutions. Descriptive results via post-experience survey were analyzed and reported. RESULTS: In total, 100% of trainees found mICMO useful. The majority would recommend to a peer, and 100% of faculty examiners found mICMO useful and would participate in another examination. CONCLUSIONS: Faculty and trainees found the experience to be effective with respect to creating a high-stakes environment, educationally beneficial, and productive. These results support the continued use of mICMO and encourage expansion and collaboration with additional institutions across the country.
