Rare cause of right heart failure: contained rupture of a sinus of Valsalva aneurysm associated intraventricular septal aneurysm.

Sinus of Valsalva aneurysm (SVA) is a rare congenital lesion described first in 1840 by John Thurnam (Cited by Boutefou JM, Moret PR, Hahn C, Hanf E. Aneurysms of the sinus of Valsalva: report of seven cases and review of the literature. Am J Med 1978;65:18-24). In most cases unruptured Sinus of Valsalva aneurysm (SVA) is clinically silent; however, if it progressively enlarges it may cause coronary artery compression, complete heart block, or right ventricular outflow tract obstruction (Meier JH, Seward JD, Miller FA, Oh J, Sarano ME. Aneurysms in the left ventricular outflow tract: clinical presentation, causes, and echocardiographic features. J Am Soc Echocardiogr 1998;11:729-45; D'Silva SA, Dalve BV, Lokhandwala YY, Kale PA, Tendolkar AG. Unruptured congenital aneurysm of the left sinus of Valsalva presenting as acute right heart failure. Chest 1992;101:578-79) or is a potential source of cerebrovascular emboli. (Shahrabani RM, Jairaj PS. Unruptured aneurysm of the sinus of Valsalva: a potential source of cerebrovascular embolism. Br Heart J 1993;69:266-67). In this report, we describe a case of right coronary sinus of Valsalva aneurysm with a contained rupture. The containing rupture is in intraventricular septal aneurysm; the patient presents with right-sided heart failure.

Enterococcus avium endocarditis.

We describe a rare case of Enterococcus avium endocarditis in a patient with an ovarian malignancy, and review 2 previously reported cases. We contend that Enterococcus avium bacteremia and endocarditis may be associated with gastrointestinal pathology.

Calcified bicuspid aortic valve mass prolapsing into the left main coronary artery.

We report a case of a mobile calcific mass on the aortic valve that prolapsed into the left main coronary artery of a 51-year-old man. This case and a review of the literature suggest that calcific embolization to coronary arteries is a rare but possibly underrecognized complication of calcified degenerative or bicuspid aortic valves. This potentially catastrophic complication of calcified aortic valves needs to be suspected and recognized in clinical practice.

Multidisciplinary education for oxygen prescription. A continuous quality improvement study.

OBJECTIVES: To examine the oxygen-prescribing habits and monitoring patterns on a medical teaching ward and to review the literature in this area. DESIGN: A continuous quality improvement study. SETTING: A 29-bed medical clinical teaching unit in a 453-bed university-affiliated tertiary care hospital. PATIENTS: We studied 50 consecutive patients who required 79 oxygen treatments. METHODS: We recorded the indication, prescriber, documentation of prior hypoxemia, method and mode of delivery, oxygenation assessment after initiation, and duration of therapy. RESULTS: Patients received oxygen for a mean (+/- SD) of 4.7 +/- 4.5 days. Oxygen therapy was ordered on a continuous basis 60.3% of the time. It was ordered by house staff in 54 cases (68%); nurses initiated oxygen therapy in 14 cases (18%) but discontinued it more often than any other health care workers. The most common indications for starting oxygen therapy were dyspnea and tachypnea. In 15 patients (30%), none of the American College of Chest Physicians and National Heart, Lung, and Blood Institute criteria for starting oxygen therapy were fulfilled. For 16 patients (32%), arterial blood gas values were measured within 1 hour of oxygen administration; for 29 patients, oximetry was performed. For 9 patients (18%), no testing of adequate oxygenation was performed within 24 hours. Oxygenation status was assessed daily for 23 patients (46%). CONCLUSIONS: Oxygen prescribing and monitoring practices were suboptimal on our busy medical teaching ward. Practice guidelines based on best available evidence are needed to increase the efficiency of oxygen use. A physiologic, multidisciplinary educational focus on the benefits and hazards of supplemental oxygen is necessary, and randomized trials of such educational interventions should be conducted.
