Background: In patients who underwent transaortic myectomy for hypertrophic obstructive cardiomyopathy (HOCM), we evaluated the role of concomitant procedures for short and long term outcome. Methods: From 1985 to 2000, in 125 patients a myectomy according to Morrow was performed. A total of 75 patients (group I) had isolated HOCM: 37 females, 38 males, mean age 52.1 years (14–79). The 50 patients of group II – 22 females, 28 males, mean age 62.4 years (36–77)-had concomitant procedures: coronary artery bypass grafting (36), mitral valve repair (15), DeVega-plasty (1), ventricular septal infarction-closure (1). Follow-up data of a total of 680.9 years (mean 5.4) were analyzed. Results: Postoperatively, left ventricular outflow tract gradients at rest and after ventricular premature beats were significantly reduced (P , 0:001). Mean performance of survivors (112/125 1⁄4 89.6%) improved significantly (P , 0:001). Perioperative complication rates: 10.7/12.0% (groups I/II), early lethality: 1.3/2.0%. Survival rates after 5/10 years were 93 ^ 3/87 ^ 6 and 80 ^ 7/80 ^ 7% for groups I and II, respectively. Conclusion: Long term results after surgical treatment of HOCM are convincing also if concomitant procedures are performed. q 2002 Elsevier Science B.V. All rights reserved.

Lipomatous hypertrophy of the interatrial septum is an uncommon entity that usually occurs in elderly patients. We report a patient who presented with atrial fibrillation, congestive cardiac failure and a large intracavitary mass in the right atrium on echocardiography. He underwent successful resection of the mass with septal reconstruction. Pathology was consistent with lipomatous hypertrophy...

We present rupture of lung hydatid cyst in a patient with multiple organ involvement during albendazole treatment. The patient was first provided mechanical ventilation than residue cavity and the other intact cyst was treated surgically. We concluded that albendazole should be used in postoperative period in patients with hydatid disease of the lung to prevent recurrent disease. q 2002 Elsevie...
