Although periprocedural myocardial infarction frequently occurs with the robustness of percutaneous coronary intervention, the prognosis of the periprocedural myocardial infarction has been known to be relatively good compared with that of spontaneous myocardial infarction. We present a patient with a postinfarction ventricular septal defect, with cardiogenic shock, that developed 7 days after a percutaneous coronary intervention. Emergency surgical repair combined with coronary artery bypass grafting saved the patient, without complications.

Near-infrared spectroscopy (NIRS) is a noninvasive technique that allows continuous monitoring of regional hemoglobin oxygen saturation (rSo2). We evaluated its application to survey oxygenation of the spinal cord region during open thoracoabdominal aortic aneurysm (TAAA) repair and postoperatively in the intensive care unit (ICU). We also validated its association with motor-evoked potential (MEP) monitoring during the operation. ⋯ NIRS is an easily applicable noninvasive tool for continuous surveillance of oxygenation of the spinal cord region during TAAA repair and postoperatively in the intensive care unit. The rSo2 curves provide useful information concerning hemodynamic changes in oxygenation of the spinal cord region and might contribute to early detection of spinal cord ischemia. Further investigation is needed before broad clinical implementation.

The bias against integrated thoracic surgery residency applicants during general surgery interviews.
New paradigms for training cardiothoracic surgeons have been introduced, including the integrated thoracic surgery residency. Currently, a limited number of these programs exist, and all candidates apply to both integrated thoracic and general surgery residencies. We sought to investigate the applicants' experiences applying for both types of positions. ⋯ The applicants to the integrated thoracic surgery residencies become interested in cardiothoracic surgery early and tailor their clinical education to this interest. Although they are academically successful, they report significant negativity regarding their applications to both general surgery and integrated thoracic residencies.

Elevated procalcitonin in patients after cardiac surgery: a hint to nonocclusive mesenteric ischemia.
Nonocclusive mesenteric ischemia (NOMI) can occur after cardiac surgery, commonly in conjunction with use of cardiopulmonary bypass. Some evidence suggests that serum procalcitonin (PCT) levels are increased in patients with mesenteric ischemia; however, an association between PCT and NOMI has not yet been studied. The current study investigates whether elevated serum PCT levels are found in patients exhibiting NOMI. ⋯ Postoperative measurement of PCT seems useful to improve the clinical and noninvasive identification of patients with NOMI after cardiac surgery.

Increased life expectancy and younger patients' desire to avoid lifelong anticoagulation requires a better understanding of bioprosthetic valve failure. This study evaluates risk factors associated with explantation for structural valve deterioration (SVD) in a long-term series of Carpentier-Edwards PERIMOUNT aortic valves (AV). ⋯ Durability of the Carpentier-Edwards PERIMOUNT aortic valve is excellent even in younger patients. Explant for SVD is related to gradient at implantation, especially in younger patients. Strategies to reduce early postoperative AV gradients, such as root enlargement or more efficient prostheses, should be considered.
