BACKGROUND:Left circumflex coronary artery (LCX) fistula is rare, and surgical experience is limited. We report our experience with 29 patients with LCX fistula during a 25-year period in terms of clinical features, pathology, surgical procedure, and late outcomes.METHODS:Between June 1988 and July 2013, 29 patients (19 males, 10 females; median age, 10 years) with LCX fistula were treated surgically and followed up. Preoperative diagnosis was made echocardiographically in 29 patients and angiographically in 17. The fistula drained into the right atrium in 12, the right ventricle in 8, left atrium and left ventricle, each in 3, main pulmonary artery in 2, and coronary sinus in 1. Surgical procedure included endocardial closure in 17 patients, epicardial closure in 5, endocardial and epicardial closure in 2, suture ligation in 1, and off-pump suture ligation in 4. Postoperative anticoagulation was prescribed for at least 6 months.RESULTS:There were no operative deaths. Complications included residual shunt in 2 patients, and LCX thrombosis, pneumothorax, hemoglobinuria, and wound infection, each in 1 patient. At the latest follow-up extending to 25 years (mean, 10.1±4.6 years), 17 patients were asymptomatic and in New York Heart Association functional class I, 4 in II and 2 in III. Residual shunt, myocardial infarction, and right atrial thrombosis occurred, each in 1 patient.CONCLUSIONS:Surgical repair of LCX fistula is safe and effective, with low risks and favorable late outcomes. Our experience implies the necessity for postoperative anticoagulation therapy to achieve good long-term outcomes.

OBJECTIVE:To investigate the clinical characteristics of primary valve tumors and the late surgical results of their resection.METHODS:We reviewed our clinical experience with the surgical treatment of ten primary valve tumors at Fuwai Hospital between November 1983 and November 2002.RESULTS:In this series, cardiac valve tumors constituted 2.65% (10/378) of all primary cardiac tumors, and the incidence of primary valve tumors was roughly one in 4000 cardiac operations. There were 5 male and 5 female patients aged 2 to 66 years (mean age, 30 years). The clinical presentations included exertional dyspnea in 7 patients, neurological symptoms in 2, and cyanosis at rest in 1 patient. The diagnosis was established by preoperative echocardiography in 8 patients, and in the other 2, it was confirmed by the findings at operation. All of the tumors were resected. Eight of the ten tumors were benign, and two were malignant. All patients survived the operation and recovered eventfully. Late outcomes were known for all patients. There were three late deaths. One patient with a benign tricuspid valve died 2 months postoperatively of an electrolyte disorder. The other 2 patients with a malignant mitral valve tumor died within 1 year postoperatively. The 7 survivors, all with a benign valve tumor, were followed up for an average of 5.7 years (range, 8 months to 19 years), and all were in functional Class I. Exercise tolerance improved to normal levels. The latest follow-up echocardiography showed no evidences of the local recurrence in any patients.CONCLUSION:Excellent early and late surgical results can be obtained in patients with benign valve tumors. The prognosis for the patients with a malignant valve tumor is poor.

BACKGROUND:Our goal was to study the clinical characteristics of primary valve tumors and the late surgical results of their resection.METHODS:We reviewed our clinical experience with the surgical treatment of ten primary valve tumors at Fu Wai Hospital over the past 19 years. During that time, cardiac valve tumors accounted for 2.65% of all primary cardiac tumors at our hospital, and the incidence of primary valve tumors was roughly one in 4,000 cardiac operations. There were 5 male and 5 female patients aged 2 to 66 years (mean age, 30.1 years). The clinical presentation included exertional dyspnea in 7 patients, neurological symptoms in 2, and cyanosis at rest in 1 patient. The diagnosis was established by preoperative echocardiography in 8 patients, and in the other 2, it was confirmed by the findings at operation. All of the tumors were resected. Eight of the ten tumors were benign, and two were malignant.RESULTS:All patients survived the operation and recovered uneventfully. Late outcomes were known for all patients. There were three late deaths. One patient with a benign tricuspid valve tumor died 2 months postoperatively of an electrolyte disorder. The other 2 patients with a malignant mitral valve tumor died within 1 year postoperatively. The 7 survivors, all with a benign valve tumor, were followed for an average of 5.7 years (range, 8 months to 19 years), and all were in functional class I. Exercise tolerance improved to normal levels. The latest follow-up echocardiograms showed no evidence of local recurrence in any patient.CONCLUSIONS:Excellent early and late surgical results can be obtained in patients with benign valve tumors. The prognosis for patients with a malignant valve tumor is poor.
