Coronary steal syndrome after coronary artery bypass for anomalous aortic origin of a coronary artery.

Anomalous aortic origin of a coronary artery found in a symptomatic 9-year-old boy was initially treated with coronary artery bypass grafting using a left internal mammary artery anastomoses to the left anterior descending coronary artery, but resulted in coronary ischemia, likely from a steal phenomenon. Subsequent transection of the proximal left internal mammary artery with anastomosis to the ascending aorta, and coronary ostial enlargement, resulted in a durable treatment. We recommend caution in choosing coronary artery bypass grafting using a left internal mammary artery pedicle graft for the treatment of anomalous aortic origin of a coronary artery

Comparison of eight prosthetic aortic valves in a cadaver model

OBJECTIVES: Proper valve selection is critical to ensure appropriate valve replacement for patients, because implantation of a small valve might place the patient at risk for persistent gradients. Labeled valve size is not the same as millimeter measure of prosthetic valve diameters or the annulus into which it will fit. Studies that use the labeled valve size in lieu of actual measured diameter in millimeters to compare different valves might be misleading. Using human cadaver hearts, we sized the aortic annulus with 8 commonly used prosthetic aortic valve sizers and compared the valves using geometric orifice area. This novel method for comparing prosthetic valves allowed us to evaluate multiple valves for implantation into the same annulus. METHODS: Aortic annular area was determined in 66 cadavers. Valve sizers for 8 prosthetic valves were used to determine the appropriate valve for aortic valve replacement. Regression analyses were performed to compare the relationship between geometric orifice area and aortic annular area. RESULTS: Tissue valves had a larger orifice area for any annular size but were not different at small sizes. Supra-annular valves were larger than intra-annular valves for the small annulus, but this relationship was not uniform with increasing annular size. CONCLUSIONS: Labeled valve size relates unpredictably to annular size and orifice area. No advantage in geometric orifice area could be demonstrated between these tissue valves at small annular sizes. Valves with the steepest slope on regression analysis might provide a larger benefit with upsizing with respect to geometric orifice area

Providing High-Quality Care for Limited English Proficient Patients: The Importance of Language Concordance and Interpreter Use

Background: Provider–patient language discordance is related to worse quality care for limited English proficient (LEP) patients who speak Spanish. However, little is known about language barriers among LEP Asian-American patients. Objective: We examined the effects of language discordance on the degree of health education and the quality of interpersonal care that patients received, and examined its effect on patient satisfaction. We also evaluated how the presence/absence of a clinic interpreter affected these outcomes. Design: Cross-sectional survey, response rate 74%. Participants: A total of 2,746 Chinese and Vietnamese patients receiving care at 11 health centers in 8 cities. Measurements: Provider–patient language concordance, health education received, quality of interpersonal care, patient ratings of providers, and the presence/absence of a clinic interpreter. Regression analyses were used to adjust for potential confounding. Results: Patients with language-discordant providers reported receiving less health education (β = 0.17, p < 0.05) compared to those with language-concordant providers. This effect was mitigated with the use of a clinic interpreter. Patients with language-discordant providers also reported worse interpersonal care (β = 0.28, p < 0.05), and were more likely to give low ratings to their providers (odds ratio [OR] = 1.61; CI = 0.97–2.67). Using a clinic interpreter did not mitigate these effects and in fact exacerbated disparities in patients’ perceptions of their providers. Conclusion: Language barriers are associated with less health education, worse interpersonal care, and lower patient satisfaction. Having access to a clinic interpreter can facilitate the transmission of health education. However, in terms of patients’ ratings of their providers and the quality of interpersonal care, having an interpreter present does not serve as a substitute for language concordance between patient and provider

Teaching About Health Care Disparities in the Clinical Setting

Clinical teachers often observe interactions that may contribute to health care disparities, yet may hesitate to teach about them. A pedagogical model could help faculty structure teaching about health care disparities in the clinical setting, but to our knowledge, none have been adapted for this purpose. In this paper, we adapt an established model, Time-Effective Strategies for Teaching (TEST), to the teaching of health care disparities. We use several case scenarios to illustrate the core components of the model: diagnose the learner, teach rapidly to the learner’s need, and provide feedback. The TEST model is straightforward, easy to use, and enables the incorporation of teaching about health care disparities into routine clinical teaching

Coronary steal syndrome after coronary artery bypass for anomalous aortic

Anomalous aortic origin of a coronary artery (AAOCA) found in a symptomatic 9 year old boy was initially treated with coronary artery bypass (CABG) using a left internal mammary artery (LIMA) anastomoses to the left anterior descending coronary artery (LAD) but resulted in coronary ischemia, likely from a steal phenomenon. Subsequent transection of the proximal LIMA with anastomosis to the ascending aorta, and coronary ostial enlargement, resulted in a durable treatment. We recommend caution in choosing CABG using a LIMA pedicle graft for the treatment of AAOCA

Conventional aortic valve replacement for elderly patients in the current era.

BACKGROUND: Because of the rising expectation of prolonged life in the general population and the recent recognition of undertreated aortic valve disease in the elderly, updating the available results of aortic valve surgery is imperative, especially considering the rapid evolution of the transcatheter valve implantation procedure. METHODS AND RESULTS: Between 1997 and 2010, 308 patients aged 70 years or older underwent aortic valve replacement (AVR) for aortic stenosis (AS). Short- and long-term results were analyzed and risk factors for long-term mortality were determined. Mean age was 78.5 years and 124 patients were aged 80 or older. Concomitant coronary artery bypass grafting (CABG) was performed in 46% of the cases. Mean left ventricular ejection fraction (LVEF) was 52%. Overall observed and expected operative mortality using the Society of Thoracic Surgeons-Predicted Risk of Mortality score was 3.9% and 4.8%, respectively. Overall survival rates at 1, 5, and 10 years were 88.6%, 71.6%, and 31.8%, respectively. Predictors of long-term mortality included diabetes; preoperative shock; LVEF ≤ 40%; New York Heart Association functional class III or IV; and age. CONCLUSIONS: Short- and long-term results of conventional AVR in the elderly prove it to be durable and, especially in relatively low-risk patients and patients who require concomitant CABG, operative mortality is reasonably low. Conventional AVR ± CABG remains the gold standard for elderly patients with AS

Access to hospital interpreter services for limited English proficient patients in New Jersey: A statewide evaluation

Context/Objectives. We surveyed New Jersey (NJ) hospitals to assess current language services and identify policy recommendations on meeting limited English proficiency (LEP) patients' needs. Methods. Survey with 37 questions regarding hospital/patient features, interpreter services, and resources/policies needed to provide quality interpreter services. Results. Sixty-seven hospitals responded (55% response rate). Most NJ hospitals have no interpreter services department, 80% provide no staff training on working with interpreters, 31% lack multilingual signs, and 19% offer no written translation services. Only 3% of hospitals have full-time interpreters, a ratio of 1 interpreter: 240,748 LEP NJ residents. Most hospitals stated third-party reimbursement for interpreters would be beneficial, by reducing costs, adding interpreters, meeting population growth, and improving communication. Conclusions. Most NJ hospitals have no full-time interpreters, interpreter services department, or staff training on working with interpreters, and deficiencies exist in hospital signage and translation services. Most NJ hospitals stated third-party reimbursement for interpreter services would be beneficial
