Patients who have dialysis-dependent renal disease frequently present with coronary artery disease but are considered at high risk for coronary artery bypass grafting. From 1 September 2000 through 31 August 2003, we performed complete off-pump coronary revascularization in 6 patients who had end-stage dialysis-dependent renal failure, and we prospectively studied the perioperative and early postoperative results. The effect of off-pump coronary artery bypass grafting on mortality, morbidity, postoperative complications, and transfusion requirements in this group of patients was investigated. ⋯ The mean duration of follow-up was 172 +/- 12.4 months. Patients with dialysis-dependent chronic renal failure who present with coronary artery disease should be thoroughly evaluated preoperatively for risk factors and coexistent severe diseases. We believe that in patients with end-stage dialysis-dependent chronic renal failure, off-pump coronary revascularization is a good alternative.

Electrical injury can cause a variety of cardiac arrhythmias. Atrial fibrillation as a result of such injury is fairly rare, however, and is rarer still in cases of low-tension electrical injury. We present the case of a patient who developed acute atrial fibrillation in association with low-voltage electrical injury, which resolved after the intravenous administration of digoxin.

Chronic tricuspid valve insufficiency secondary to blunt chest trauma is rare in the pediatric population, with fewer than 10 cases reported. Surgical repair has focused on the tricuspid valve. We present 2 cases of traumatic tricuspid valve insufficiency in pediatric patients after blunt chest trauma in whom tricuspid valve repair was performed along with superior cavopulmonary anastomosis. To our knowledge, this is the 1st report of the use of this combination of surgical procedures for repair of traumatic tricuspid regurgitation in either adults or children.

A 41-year-old woman had acute respiratory failure related to a myocardial infarction. Attempts at orotracheal intubation were unsuccessful; therefore, an emergency percutaneous tracheostomy was performed. ⋯ After the tracheostomy cannula was removed, the patient recovered successfully and was discharged from the hospital. The percutaneous tracheostomy technique may be useful in similar patients who need emergency airway access.
