Bronchopleural fistula and empyema are serious complications after thoracic surgical procedures, and their prevention is paramount. Herein, we review our experience with routine prophylactic use of the pedicled ipsilateral latissimus dorsi muscle flap. From January 2004 through February 2006, 10 surgically high-risk patients underwent intrathoracic transposition of this muscle flap for reinforcement of bronchial-stump closure or obliteration of empyema cavities. ⋯ Two patients retained peri-flap air that required no surgical intervention. We conclude that the use of transposed pedicled latissimus dorsi muscle flap effectively and reliably prevents clinically overt bronchopleural fistula and recurrent empyema. We advocate its routine use in first-time and selected reoperative thoracotomies in patients who are undergoing high-risk lung resection or reparative procedures.

Review Meta Analysis
Statin therapy may influence the incidence of postoperative atrial fibrillation: what is the evidence?
Atrial fibrillation is the most common postoperative arrhythmia in patients who undergo cardiac surgery. We sought to determine whether the administration of statins reduces the incidence of postoperative atrial fibrillation in cardiac surgery patients. We performed a meta-analysis on all studies published between 2004 and 2008 that reported comparisons between statin treatment or nontreatment in these patients. ⋯ In studies wherein only coronary artery bypass grafting was performed, statin treatment decreased postoperative atrial fibrillation (OR, 0.64; 95% CI, 0.43-0.95). We conclude that statin administration results in a reduction in the incidence of atrial fibrillation in patients who undergo cardiac surgery. Further research into the underlying mechanism can elucidate possible relationships between the dosage and type of statin used.

We sought to evaluate retrospectively the outcomes of patients at our hospital who had moderate ischemic mitral regurgitation and who underwent coronary artery bypass grafting (CABG) alone or with concomitant mitral valve repair (CABG+MVr). A total of 83 patients had a reduced left ventricular ejection fraction and moderate mitral regurgitation: 28 patients underwent CABG+MVr, and 55 underwent CABG alone. Changes in mitral regurgitation, functional class, and left ventricular ejection fraction were compared in both groups. ⋯ In patients with moderate ischemic mitral regurgitation, either surgical approach led to an improvement in functional class. Early and intermediate-term mortality rates were low with either CABG or CABG+MVr. However, an increased rate of late recurrent mitral regurgitation in the CABG+MVr group was observed.
