Case ReportsLeft atrial myxoma associated with obstructive coronary artery disease.
We describe a case of a 67 year-old patient with obstructive coronary artery disease that, in the preoperative survey for inguinal herniorraphy surgery, discovered, by a two-dimensional echocardiogram, a tumor in left atrium, mobile, non-obstructive. The patient underwent a cineangiocoronariography showing severe stenosis in the left anterior descending artery, moderate stenosis in the left circumflex artery, near the origin of the first marginal branch, and a non-obstructive plaque in the right coronary artery. ⋯ After that, the patient has gone coronary artery bypass surgery and resection of the left atrial tumor. The histological exam revealed that the tumor was, in fact, a myxoma.

Analysis of ventilation and hemodynamic changes resulting from noninvasive bilevel pressure mechanical ventilation applied to patients with congestive heart failure.
To observe in practice how noninvasive bilevel positive pressure, applied at different levels, may interfere with systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), and peripheral oxygen saturation (SpO2), in patients with congestive heart failure (CHF). ⋯ Noninvasive bilevel mechanical ventilation improves oxygenation and reduces respiratory work, thus being beneficial for patients with congestive heart failure. It was not possible to observe statistically significant changes in the hemodynamic data due to the small number of patients and to other associated heart diseases.
