Mitral valve repair with artificial chordae replacement in children: a single-center experience.

OBJECTIVES:To summarize the experience of mitral valve (MV) repair with artificial chordae replacement in children, and analyze early and intermediate outcomes.METHODS:From January 2011 to May 2019, all patients (< 18 years) who received MV repair with artificial chordae replacement were retrospectively reviewed. Freedom from MV reoperation, MV dysfunction, moderate or severe MR were estimated by the Kaplan-Meier curve and log-rank test.RESULTS:A total of 30 patients were included in this study. According to our definition, 15 patients had simple lesions and 15 patients had complex lesions. During 36 months' follow-up (range 3-97 months), two patients received MV reoperation and seven patients developed MV dysfunction, including six patients with moderate or severe MR and one patient with mitral stenosis. Freedom from MV reoperation at 1, 5 and 8 years were 100%, 91.3% and 91.3%, respectively. And freedom from MV dysfunction at 1, 3 and 5 year were 96.0%, 77.1% and 61.8%, respectively. Five-year freedom from MV dysfunction showed significant differences between patients with simple lesions and patients with complex lesions (100% vs 32.7%, log-rank P = 0.008), and between patients aged less than 12 years and patients aged more than 12 year (33.5% vs 90.0%, log-rank P = 0.025).CONCLUSION:The early and intermediate outcomes of mitral valve repair with artificial chordae replacement were acceptable in children, and the outcomes were optimal in patients with simple lesions, and patients aged more than 12 years.

Surgical treatment for primary mitral valve tumor: a 25-year single-center experience.

OBJECTIVE:Primary mitral valve (MV) tumor is a rare lesion, and to date, there have been few larger surgical series of MV tumors. We retrospectively analyzed 11 cases of primary MV tumors regarding clinical and pathological features, surgical procedure and long-term outcomes.METHODS:From November 1983 to December 2008, we operated on 11 patients (age 36.3 ± 17.7 years, weight 55.4 ± 11.2 kg) with primary MV tumors. Symptoms were cardiac in 8 cases (72.7%) and neurologic in 3 (26.3%). Surgical procedures included en bloc excision and MV repair in 8 cases and tumor resection and MV replacement in 3. No radiotherapy or chemotherapy was given to patients with malignant tumors.RESULTS:Pathological diagnosis was papillary fibroelastoma in 3 cases, myxoma in 3, lymphangioma in 1, lipoma in 1, hemangioma in 1 and sarcoma in 2. No early deaths or complications occurred. Late death occurred in 2 patients with sarcoma 1 year postoperatively. At the latest follow-up, with a maximum of 25 years (mean 10.6 ± 8.8), the 9 survivors were in New York Heart Association functional class I with normal MV function and no echocardiographic evidence of local recurrence.CONCLUSIONS:The majority of primary MV tumors are benign. They can cause cardiac or neurologic symptoms and should be excised as soon as a diagnosis is made. For benign tumors, valve-sparing resection and valve repair are often possible with excellent long-term outcomes. The prognosis of malignant MV tumors is poor.

Surgical and transcatheter closure of right pulmonary artery to left atrial fistula.

BACKGROUND AND AIM OF THE STUDY:Right pulmonary artery to left atrium fistula is a very rare cardiac malformation. We sought to describe our experience with surgical and transcatheter treatment of this defect in three cases.MATERIAL AND METHODS:Between October 2000 and October 2009, three patients with right pulmonary artery to left atrial fistula were treated at our institute. They were all males and aged 23, 7, and 14, respectively. They presented with cyanosis with clubbing of fingers and toes in three cases, and exertional dyspnea in two. Laboratory tests showed elevated hemoglobin and decreased systemic arterial oxygen saturation. Preoperative diagnosis was made by echocardiography and cardioangiography. The fistula was closed surgically in two patients either by simple ligation without cardiopulmonary bypass or by suture of the fistula from inside the right pulmonary artery lumen under cardiopulmonary bypass. In the third patient, the fistula was occluded with an 18-mm Amplatzer septal occluder (AGA Medical, Plymouth, MN, USA).RESULTS:The systemic oxygen saturation rose up to above 96% immediately after the procedures. No operative or procedural complication and late deaths occurred. All three patients were asymptomatic on follow-up.CONCLUSIONS:Both surgical and transcatheter closure are safe and reliable treatment for patients with right pulmonary artery to left atrial fistula. The treatment should be individualized and performed as soon as the diagnosis is made.

[Surgical treatment of giant coronary artery aneurysm].

OBJECTIVE:To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA).METHODS:From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction. The giant CAA was often combined with other cardiac diseases. Four cases underwent additional procedures of fistula closure, 3 aortic valve replacements, 2 aortoplasty and 1 thrombus cleaning at the same time.RESULTS:All patients recovered uneventfully. The mean of cardiopulmonary bypass time was (144 +/- 26) min (range 67 to 207 min). Aortic cross clamping time was (104 +/- 21) min (range 56 to 172 min). Patients follow-up time occurred from 8 to 87 months (mean of 48 months). All patients were free of symptoms during follow-up. None of the patients died during the follow-up period and none of the CAA recurred.CONCLUSIONS:The giant CAA is a serious cardiovascular disease, early diagnosis and surgical treatment are mandatory.

Surgical treatment of giant coronary artery aneurysm.

OBJECTIVE:Giant coronary artery aneurysm is an extremely uncommon disease. Most previous reports have involved only single cases. This report describes 6 patients with giant coronary artery aneurysm, examines its causes, and aims to establish the optimal surgical strategies for this exceptional and rare pathology.METHODS:From July 1996 to October 2004, a total of 30,268 patients underwent heart surgery at Fuwai Hospital in Beijing. Among these, 6 patients had giant coronary artery aneurysm diagnosed and underwent operation. Various surgical strategies were used for the operations of these 6 patients, such as coronary artery aneurysm resection, coronary artery reconstruction, and concomitant coronary bypass. Additional procedures, such as fistula closure, aortic valve replacement, aortoplasty, and embolectomy, were done at same time for the patients with complications of coronary fistula, aortic valve insufficiency, or thrombus. Patients were followed up from 8 to 87 months, with a mean of 48 months. Doppler echocardiography, ultrafast computed tomography, and 3-dimensional aerial image studies were performed during follow-up.RESULTS:Five of these six cases were found combined with coronary artery fistula, and the cause for these giant coronary artery aneurysms was congenital. The remaining case was caused by atherosclerosis. After surgery, all patients recovered uneventfully, without in-hospital mortality. None died during the follow-up, nor did any have recurrence of the symptoms or giant coronary artery aneurysm.CONCLUSION:Giant coronary artery aneurysm is a rare entity that is commonly caused by congenital malformation and combined with other cardiac anomalies. An optimal surgical operation should be based on the specific cardiac anomaly of the individual patient.

Correction of traumatic tricuspid insufficiency using the double orifice technique.

Traumatic tricuspid insufficiency is an uncommon clinical condition and surgical procedures vary. In this paper we report our experience in treating traumatic tricuspid insufficiency using the double orifice technique. From January 2000 to September 2003, 10 patients with traumatic tricuspid regurgitation were admitted to our hospital, 5 of whom were corrected using the double orifice technique. There were 4 males and 1 female with ages ranging from 31 to 52 years. Preoperative transthoracic echocardiography (TTE) detected severe tricuspid regurgitation in 4 patients and moderate tricuspid regurgitation in 1 patient. At surgery, tear of the tricuspid anterior papillary muscle was found in 2 cases and anterior chordal rupture in 3 cases. The valves were successfully repaired using the double orifice technique in combination with ring annuloplasty. There was no repeat operation, no operative complications or deaths. Before discharge, TTE detected normal tricuspid valve function in 2 cases and tiny regurgitation in 3 cases. After a follow up of 8 to 36 months, TTE demonstrated normal valve function in 1 patient and tiny regurgitation in 4 patients. The double orifice technique appears to be a simple but effective method of repairing traumatic tricuspid incompetence. Satisfactory clinical outcomes can be produced in carefully selected patients.
