ABSTRACT
BACKGROUND: The recurrence of cardiac myxoma after a surgical excision is a rare condition. The mechanism responsible for the recurrence remains unclear. Multifocal growth of a benign myxoma or malignant transformation, inadequate resection, intraoperative implantation or embolization, familial disposition, and the abnormal DNA ploidy pattern play an important role in development of recurrent myxoma. CASE: We report the case of a 24-year-old female with recurrent multiple cardiac myxomas. She had an abortus 2 months ago. The patient had undergone a resection of left atrial and right ventricular myxoma with extension to the right pulmonary artery 8 years ago. The preoperative echocardiographic examinations revealed recurrent left atrial and right and left ventricular myxomas. The patient underwent a redo-surgery and, in addition to a large myxoma in the right ventricle with involvement of the tricuspid valve and anterior papillary muscle, three myxomas including both myxomas originating at the top and the base of the posterior papillary muscle, respectively, the other myxoma between both papillary muscles in the posterior wall of the left ventricle, and 2 more small myxomas including 1 in the interatrial septum and the other on atrial surface of anterior mitral annulus were found in the left ventricle and atrium. The myxomas were successfully excised through a transmitral approach with a combined bi-atrial incision. The tricuspid valve and mitral valve were repaired with annuloplasty. She had an uneventful postoperative course and no residual myxoma was found by echocardiography. CONCLUSION: We think that a long-term follow-up by echocardiography in all patients after the resection of myxoma is advised for an early detection of any recurrence (Fig. 5, Ref. 9).

Traumatic aortic valve regurgitation is a rare complication of non penetrating blunt chest trauma which usually requires surgical management. We describe a case of a 21 year old man with blunt chest trauma who was diagnosed with aortic valve regurgitation due to rupture of the right coronary cusp one month after falling from a high place. Rupture of aortic valve cusp was treated successfully with aortic valve replacement.

The effect of cardiopulmonary bypass and myocardial ischaemia on the occurrence of atrial fibrillation (AF) after coronary artery bypass graft (CABG) was studied in 136 patients undergoing off-pump CABG who were matched for age and number of distal anastomoses with 136 patients undergoing on-pump CABG. Possible risk factors for post-operative new-onset AF were recorded. AF occurred in 64 (24%) of the 267 patients for whom data could be analysed. AF occurred in 29 patients (22%) in the off-pump group versus 35 (26%) in the on-pump group, but this difference was not statistically significant. On univariate analysis, age and length of hospital stay were significant risk factors for the occurrence of AF. In a multivariate analysis that included operative technique, age was found to be the only significant risk factor. In conclusion, the occurrence of AF after CABG does not depend on the type of operation.

Aortic insufficiency may be either acquired or congenital. A 46-year-old male had a congenital pathology which resulted in aortic insufficiency due to the presence of a fibrous band that stretched from the non-coronary cusp to the aortic wall. The patient underwent successful aortic valve replacement. At surgery, the fibrous band was stretching the non-coronary cusp so that it prevented coaptation of the aortic valve. The situation was termed by us as the 'kite anomaly'.
