TL;DR: The data suggest that prior to operation, operative mortality can be best predicted by urgency of operation and left ventricle ejection fraction, and afterwards, prognostic factors include preoperative LVEF < or = 35%, non-elective operation, and prolonged cardiopulmonary bypass time.
Abstract: Background: The purpose of this study was to determine the factors which can help to predict operative mortality before performing the operation, and afterwards. Methods: The study population consisted of 504 patients (91 women and 413 men) who underwent primary isolated coronary artery bypass surgery from December 1997 to September 1999 by the same surgeon in a referral center in Tehran, Iran. Perioperative data were gathered and analyzed both in a univariate and multivariate model. Results: After the operation patients spent 7.3 ^ 4.0 days in hospital. The total operative morbidity was 20.5%. Arrhythmias were the most common complication, with atrial fibrillation as the predominant feature. Major complications of the operation were: low cardiac output (4.2%); prolonged ventilatory support (2.4%); hemorrhage and exploratory reoperation (2.0%); postoperative myocardial infarction (1.4%); postoperative renal failure in (1.4%); and postoperative cerebrovascular accident (0.8%). Operative mortality rate in this study was 2.98%. Factors associated with high operative mortality in univariate analysis were: recent myocardial infarction, low ejection fraction, non-elective operation, left main coronary artery disease and prolonged cardiopulmonary bypass time. Conclusion: Our data suggest that prior to operation, operative mortality can be best predicted by urgency of operation and left ventricle ejection fraction. After performing the operation, prognostic factors include preoperative LVEF # 35%, non-elective operation, and prolonged cardiopulmonary bypass time. Further study is required to assess the generalization of our findings to Iranian patients. q 2002 Elsevier Science B.V. All rights reserved.

TL;DR: A case of non-familial cardiac myxoma, which after successful resection of the tumor mass from the left atrium, recurred in the atrial surface of anterior leaflet of the mitral valve, along with a review of similar cases in the literature.
Abstract: Recurrence of intracardiac myxoma is unusual, and heart valves are extremely rare locations for this tumor to originate, either as the primary site or the site of recurrence. We present a case of non-familial cardiac myxoma, which after successful resection of the tumor mass from the left atrium, recurred in the atrial surface of anterior leaflet of the mitral valve, along with a review of similar cases in the literature. Myxoma was originally believed to recur due to inadequate resection, but recent data suggest the multicenteric disease to be the reason. Mitral valve myxoma mainly presents with symptoms of embolization and appears to affect women more often. It involves both leaflets with the same frequency and usually originates from the atrial side. Transesophageal echocardiography is the gold standard for non-invasive diagnosis and localization. Operative resection of the tumor along with the underlying tissue followed by suture repair of the valve and annuloplasty is recommended as the most appropriate treatment option. Long-term follow-up of patients by echocardiography is advised for early detection of any recurrence.
