Cardiac papillary fibroelastomas are the second most common primary cardiac tumor. This tumor is usually benign and it involves the cardiac valve. However, most cardiac papillary fibroelastomas originate from a single site, and the incidence of cardiac papillary fibroelastomas originating from multiple sites is very rare (5%). A 55-year-old woman who presented with momentary dizziness and syncope was evaluated by performing echocardiography. Multiple tumors attached to the aortic valve were noted. The mass was removed freely without leaving any defect on the aortic valve leaflet. After the recovery period, the patient is currently being followed up at the outpatient department.

BACKGROUND: The purpose of this study was to identify factors associated with recurrent pneumothorax after wedge resection in primary spontaneous pneumothorax in our hospital. MATERIAL AND METHOD: Two hundred thirty-five consecutive patient (98% males; mean age, 23.9+/-4.5 years) who had undergone video-assisted thoracoscopic surgery (VATS) were reviewed retrospectively. The two groups were divided as follows: group A, non-recurrent patients (225 patients [96%]); and group B, recurrent group (10 patients [4%]); the risk factors were compared between the two groups. The single and multiple factors that influenced the recurrence rate were analyzed using Cox's proportional hazard model. RESULT: There were no significant differences between the recurrent and non-recurrent groups in terms of gender, smoking, site of recurrence, degree of collapse, operative time, and number or weight of resected bullae. The recurrence rate was significantly more common in the following: younger ages, increased height/weight ratio, longer initial air leakage period, and shorter duration of chest drainage. Early aggressive exercise (<30 days) of patients after wedge resection increased the tendency for recurrence. CONCLUSION: Thoracoscopic wedge resection does not have a higher recurrence rate than open thoracotomy. However, young age, height/weight ratio, continuous air, and duration of chest tube placement were risk factors for a recurrent pneumothorax.

Extracorporeal membrane oxygenation (ECMO) provides mechanical cardiopulmonary support and has been used for children with severe respiratory failure, intractable heart failure, sepsis, pulmonary hypertension, and as a bridge to heart transplantation. There have been few reports of the use of ECMO to provide cardiac support in children with low cardiac output as a result of arrhythmias. We report the case of a 15-year-old female with circulatory collapse due to refractory ventricular arrhythmia after one and a half repair in Ebstein's anomaly, who was successfully resuscitated using ECMO.
