Coma might not preclude emergency operation in acute aortic dissection.

BACKGROUND: Syncope or new onset focal neurologic deficits are described in as many as one fifth of patients with acute aortic dissection referred for surgery. Coma or stroke caused by involvement of the arch vessels and secondary brain malperfusion is considered a major contraindication for emergency aortic repair. Initial experience with emergency operation in selected patients with acute type A aortic dissection complicated by coma is described. METHODS: Five comatose (median Glasgow coma score, 5.5), hemodynamically stable (systolic blood pressure > or = 100 mm Hg) patients with preserved pupillary reactivity and coma duration of less than 12 hours underwent emergency surgical repair. The ascending aorta was always replaced using profound hypothermic circulatory arrest. RESULTS: There were no operative deaths. No hemorrhagic brain infarction developed postoperatively. Ischemic strokes were documented by radiology in 3 patients, and were always right-sided. Four patients returned to normal life with no neurologic sequelae, whereas 1 patient showed partially recovered left hemiparesis and mild cognitive impairment. CONCLUSIONS: Coma may not represent an absolute contraindication for resuscitative surgery in hemodynamically stable patients with acute type A aortic dissection. A larger experience is necessary to draw more definitive conclusions.

Early surgical anteroseptal ventricular endocardial restoration after acute myocardial infarction. Pathophysiology and surgical considerations.

BACKGROUND: The efficacy and safety of surgical anteroseptal ventricular endocardial restoration (a procedure that excludes non-contracting scarred segments) in the left ventricle with chronic dilation and remodeling secondary to an anterior myocardial infarction are well established. We present a small series and discuss the indication for early left ventricular restoration in the setting of complicated acute myocardial infarction. METHODS: Early ventricular restoration was performed in 8 patients (4 males, 4 females, mean age 70 +/- 8 years). A postinfarction ventricular septal defect was diagnosed in 3 cases. All patients were operated, on an urgent or emergent basis, between 1 and 16 days following the onset of infarction. Surgical coronary revascularization was associated in 7 patients. RESULTS: There was one operative death. At discharge, echocardiographic morphofunctional assessment revealed: a reduction of the left ventricular end-diastolic and end-systolic volume indexes, an increase of the ejection fraction, and, most importantly, an improvement of remote myocardial shortening fraction. At a mean follow-up of 15.6 months (range 2-21 months), there were no late deaths and all survivors are in NYHA functional class I or II. CONCLUSIONS: Left ventricular restoration may represent an effective adjunct to the surgical management of patients with an acute extensive anterior myocardial infarction complicated by severe heart failure, with or without septal rupture.

[Resection of unusual atrial mass complicated with fungal endocarditis in a patient undergoing immunosuppressive treatment].

Nodules of mesothelial and monocytic cells (Mesothelial/Monocytic Incidental Cardiac Excresences; MICE) are rare cardiac lesions, non neoplastic, possibly reactive and in part derived from mesothelium. A 76 years old woman, treated with low dose of steroid and methotrexate for rheumatoid arthritis, underwent surgical excision of cardiac "MICE". Postoperative period was complicated with early and severe fungal endocarditis requiring reintervention. Two aspects are of interest: rarity of both cardiac pathologies and the possible relation to immunosuppressive therapy. Treatment of fungal endocarditis should be aggressive, overall survival is rather poor. Possibility to discontinue immunosuppressive treatment should be considered before cardiac surgery.
