Randomized Controlled Trial Comparative Study
Subxiphoid versus intercostal chest tubes: comparison of postoperative pain and pulmonary morbidities after coronary artery bypass grafting.
Chest tubes are one cause of pain after cardiac surgery. In a prospective, randomized study, we investigated the effects of the position of chest tubes on acute postoperative pain and pulmonary morbidities in patients who underwent coronary artery bypass grafting. From June through December 2010, 40 patients who underwent elective coronary artery bypass grafting were enrolled in the study. ⋯ Pleural effusion and atelectasis were each diagnosed in 3 patients in Group 1 (15%) and 1 patient in Group 2 (5%) (both P=0.68). Two of the patients in Group 1 required drainage of the pleural effusion. In our study, we found that the subxiphoid and intercostal approaches for chest-tube placement yielded similar clinical outcomes.

We report a case of mitral valve replacement in a patient who had previously undergone transcatheter aortic valve implantation. A transseptal approach was used to avoid displacing the aortic prosthesis. Because of the small mitral annulus, a bioprosthetic aortic valve was used in reverse position for mitral valve replacement. ⋯ To the best of our knowledge, this is the first report of mitral valve replacement in a patient who had a preceding transcatheter aortic valve implantation. We believe that the transseptal approach is promising for mitral valve replacement in such patients. Moreover, using a bioprosthetic aortic valve in reverse position is an option for mitral valve replacement when the mitral annulus is too small for placement of a standard bioprosthetic mitral valve.

Since the implantable cardioverter-defibrillator was first used clinically in 1980, several large randomized controlled trials have shown that therapy with this device can be beneficial in various patient populations. Evidence suggests that this therapy is useful in the secondary prevention of sudden cardiac death among patients who have survived arrhythmic events. ⋯ When used with cardiac resynchronization therapy, implantable cardioverter-defibrillators have improved survival rates and quality of life in patients with severe heart failure. Further research is needed to examine the potential benefits of implantable cardioverter-defibrillators in elderly, female, and hemodialysis-dependent patients, and to determine the optimal waiting period for implantation after myocardial infarction, coronary revascularization, and initial heart-failure diagnosis.

Case Reports
Minimally invasive retrieval of patent foramen ovale closure device after device migration to the descending aorta.
Percutaneous treatment of patent foramen ovale with a septal closure device has become a common procedure, but it is associated with various complications. Migration of the device is uncommon, and migration through the aortic valve into the aorta is rare. ⋯ We report a rare case in which a patient experienced migration of a large patent foramen ovale closure device to the descending aorta. Rarer still was its successful percutaneous management.

Scimitar syndrome and gastrointestinal bleeding from an aberrant right subclavian artery-esophageal fistula are each extremely rare. Although scimitar syndrome and aberrant right subclavian artery are typically asymptomatic in adults, fistulous connection between the aberrant artery and the esophagus is associated with a poor prognosis. Outcomes are contingent upon timely diagnosis and prompt surgical repair. ⋯ We report the case of a 57-year-old woman in whom an aberrant right subclavian artery-esophageal fistula developed after surgical correction of symptomatic scimitar syndrome. Massive gastrointestinal bleeding resulted from prolonged nasogastric and endotracheal intubation. To our knowledge, this is the first report of aberrant right subclavian artery and scimitar syndrome in the same patient, and the 4th report of a patient's surviving a fistula between the aberrant artery and the esophagus.
