We conducted a study to compare medical school experiences, values, career paths, and career satisfaction of under-represented in medicine (URiM) and non-URiM physicians approximately 15 years after medical school, guided by the Theory of Planned Behavior and the concept of stereotype threat. The sample consisted of four graduating classes, 1996-1999, of Harvard Medical School, 20% of whom were URiM. URiM respondents came from families of lower educational attainment and graduated with more debt. As students, they reported a greater experience of stereotype threat and, and at graduation they showed a tendency to place a higher value on avoiding a career that places them under constant pressure. Concerning their current status, URiM respondents expressed a lower level of satisfaction with their career progress. Multivariable analyses indicated that across the entire sample, URiM status was not a significant predictor of employment in academic medicine, but that being in academic medicine was predicted by mentors' encouragement for a research career, greater intention to pursue research, and a lower value on having a financially rewarding career. Lower career satisfaction was predicted by one's status as URiM, employment in academic medicine, greater involvement in research, and a greater value on avoiding constant pressure. The data suggest that negative student experiences in medical school, combined with the lack of mentor encouragement and financial pressures may discourage URiM medical students from pursuing academic careers, and that pressures for productivity and working in academic medicine may degrade the satisfaction derived by physicians in general.

Arterial cannulation with a chimney polytetrafluoroethylene graft to the innominate artery is commonly used for antegrade cerebral perfusion during neonatal aortic arch surgery. When properly retained and prepared before sternal closure, resuscitation of the polytetrafluoroethylene graft to innominate artery can be performed months later during sternal reentry. It is a safe and reproducible technique for expeditious arterial cannulation at stage II palliation in single-ventricle patients or complete intracardiac repair of biventricular lesions. We report our experience utilizing this technique successfully during reoperation in 90 of 92 patients, with no adverse thromboembolic events identified.

BACKGROUND

Class 1C antiarrhythmic drugs (AADs) are effective first-line agents for atrial fibrillation (AF) treatment. However, these agents commonly are avoided in patients with known coronary artery disease (CAD), due to known increased risk in the postmyocardial infarction population. Whether 1C AADs are safe in patients with CAD but without clinical ischemia or infarct is unknown. Reduced coronary flow capacity (CFC) on positron emission tomography (PET) reliably identifies myocardial regions supplied by vessels with CAD causing flow limitation.

OBJECTIVE

To assess whether treatment with 1C AADs increases mortality in patients without known CAD but with CFC indicating significantly reduced coronary blood flow.

METHODS

In this pilot study, we compared patients with AF and left ventricular ejection fraction ≥50% who were treated with 1C AADs to age-matched AF patients without 1C AAD treatment. No patient had clinically evident CAD (ie, reversible perfusion defect, known ≥70% epicardial lesion, percutaneous coronary intervention, coronary artery bypass grafting, or myocardial infarction). All patients had PET-based quantification of stress myocardial blood flow and CFC. Death was assessed by clinical follow-up and social security death index search.

RESULTS

A total of 78 patients with 1C AAD exposure were matched to 78 controls. Over a mean follow-up of 2.0 years, the groups had similar survival (P = .54). Among patients with CFC indicating the presence of occult CAD (ie, reduced CFC involving ≥50% of myocardium), 1C-treated patients had survival similar to (P = .44) those not treated with 1C agents.

CONCLUSIONS

In a limited population of AF patients with preserved left ventricle function and PET-CFC indicating occult CAD, treatment with 1C AADs appears not to increase mortality. A larger study would be required to confidently assess the safety of these drugs in this context.
