Successfully Treated Nonocclusive Mesenteric Ischemia After Transcatheter Aortic Valve Replacement.
An 80-year-old man with symptomatic severe aortic stenosis underwent transcatheter aortic valve replacement. Postoperatively, the patient was hemodynamically stable without inotropic or mechanical support. ⋯ We suspected nonocclusive mesenteric ischemia and performed emergency selective angiography of the superior mesenteric artery, which showed vasospasm. We confirmed the diagnosis of nonocclusive mesenteric ischemia, and it was treated successfully with intraarterial infusion of vasodilators into the superior mesenteric artery.

Minocycline-induced hyperpigmentation of tissues has been documented previously, but extensive cardiovascular involvement is rarely described in literature. We report a case of marked cardiovascular hyperpigmentation resulting from approximately 4 years of minocycline exposure. We will highlight how intraoperative differentiation of minocycline-induced hyperpigmentation from more sinister causes of discoloration led to the appropriate surgical management.

Bilateral internal thoracic artery (BITA) grafting in patients with diabetes mellitus is controversial because of a higher risk for sternal infection. The purpose of this study is to compare the outcome of BITA grafting to that of single ITA (SITA) grafting in patients with diabetes. ⋯ The findings of this large cohort study suggest that the long-term outcome of patients with diabetes and multivessel disease who undergo BITA grafting is better than that of diabetic patients who undergo coronary artery bypass graft surgery with SITA and saphenous vein grafts.

Pulmonary Valve Replacement With a Trifecta Valve Is Associated With Reduced Transvalvular Gradient.
Outcomes after surgical pulmonary valve replacement (PVR) in patients with congenital cardiac disease are limited by long-term valve deterioration, which may be hastened by turbulent flow. The use of the Trifecta valve (St. Jude Medical, Little Canada, MN) at our institution (Duke University Medical Center, Durham, NC) appears to result in low postimplantation transvalvular gradients. This study was performed to compare the early transvalvular gradient associated with the Trifecta valve with that associated with two other valves commonly used for PVR. ⋯ PVR for congenital heart disease with the Trifecta bioprosthetic valve is associated with a reduced early transvalvular gradient. This finding may be associated with reduced valve deterioration over time.

The Physician Payment Sunshine Act was implemented to provide transparency to financial transactions between industry and physicians. Under this law, the Open Payments Program (OPP) was created to publicly disclose all transactions and inform patients of potential conflicts of interest. Collaboration between industry and cardiothoracic surgeon-scientists is essential in developing new approaches to treating patients with cardiac disease. The objective of this study is to characterize industry payments to cardiothoracic surgeons as reported by the OPP. ⋯ Among cardiothoracic surgeons who are listed as recipients of nonresearch industry payments, 50% of cardiothoracic surgeons received less than $181. Awareness of the OPP data is critical for cardiothoracic surgeons, as it provides a means to prevent potential public misconceptions about industry payments within the specialty that may affect patient trust.
