We explored the efficacy of laparoscopic fundoplication (LF) in patients with uncomplicated, medically recalcitrant pathologic gastroesophageal reflux disease (GERD) for whom we previously would have recommended open surgical repair. ⋯ Intermediate-term results with LF suggest this to be a reasonable approach to surgical management of medically recalcitrant uncomplicated GERD. Thoracic surgeons interested in GERD should become familiar with minimally invasive surgical approaches.

We investigated whether percutaneous cannulation of the coronary sinus could be accomplished without fluoroscopy using transesophageal echocardiography in patients undergoing minimally invasive cardiac operations. The coronary sinus was cannulated without significant complications using transesophageal echocardiography in 10 of 11 patients (mean, 10.5 minutes). Percutaneous cannulation of the coronary sinus can be accomplished in a safe and efficient manner using transesophageal echocardiography without the need for fluoroscopy.

Neurologic complications, primarily resulting from ischemic insults, represent the leading cause of morbidity and disability, and the second most common source of death, after cardiac operations. Previous studies have reported that increases (as occur during the rewarming phase of cardiopulmonary bypass [CPB]) or decreases in brain temperature of a mere 0.5 degrees to 2 degrees C can significantly worsen or improve, respectively, postischemic neurologic outcome. The purpose of the present study was to evaluate a novel approach of selectively cooling the brain during hypothermic CPB and subsequent rewarming. ⋯ The magnitude of selective brain cooling observed in both study groups typically exceeded the 0.5 degrees to 2.0 degrees C change previously reported to modulate ischemic injury, and was most prominent during the latter phases of CPB. When compared with previous research from our laboratory, application of cold forced air to the cranial surface resulted in brain temperatures that were cooler than those observed during hypothermic CPB without pericranial cooling. On the basis of the assumption that similar beneficial brain temperature changes can be induced in humans, we speculate that selective convective brain cooling may enable clinicians to improve neurologic outcome after hypothermic CPB.

The aim of this study was to determine the long-term survival and control of angina in patients with coronary artery disease and sequentially decreased ejection fractions (EF) after first-time coronary artery bypass grafting. ⋯ In the long term there is a higher mortality in patients with sequentially decreased left ventricular function undergoing coronary artery bypass grafting, although more than 60% of patients with an EF less than 0.25 were alive and had good control of angina at 5 years despite having a higher percentage of risk factors, poorer functional status, and more complex coronary disease. Failure of symptom control and survival beyond 5 years appeared to be influenced by preexisting medical conditions and factors that affect the ability to completely revascularize the myocardium. These results suggest that in selected patients with ischemia and poor left ventricular function, coronary artery bypass grafting may preserve remaining viable myocardium, provide relief of symptoms, and offer survival greater than 60% at more than 5 years.
