        • Surgical Treatment of Primary Deep Venous Valvular incompetence of Lower Limb

          Objective To evaluate the surgical effects of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins stripping on primary deep venous valvular incompetence of the lower limb.Methods Seventy-eight patients (92 limbs) with primary deep venous valvular incompetence of the lower limbs received the operations of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins from 1997 to 2004. There were 65 males and 13 females, and their ages ranged from 32 years to 72 years (mean age of 52.5 years). The valvular reflux grades of these 92 limbs varied from Ⅲ to Ⅳ according to Kistner’s standard. A sleeve made from the stripped great saphenous vein was used in the indirect loop valvuloplasty of the superficial femoral vein. The early results of surgery were retrospectively analyzed. Results Pre-operative symptoms, such as edema, ulceration, pigmentation and heavy feeling of the performed limbs disappeared or were remarkably improved in 65 cases (76 limbs) after operation. Eight cases (10 limbs) had alleviative symptoms compared with pre-operative ones. Meanwhile, no improvement of symptoms was observed in 3 patients (4 limbs). Acute ilio-femoral vein thrombosis occurred in 2 patients (2 limbs), which manifested as more servious edema of the lower limbs than those before operation. The overall effective rate of surgery was 93.5%(86/92), and the complications rate was 2.2% (2/92). Conclusion Indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose vein stripping is an effective and convenient way to correct the primary deep venous valvular incompetence of the lower limb. The surgical indications of this disease should be emphasized strictly to assure the good outcomes.

        • Clinical Application of Homemade Flexible Annuloplasty Ring in Mitral Valve Repair

          Abstract: Objective To summarize the clinical results of homemade flexible annuloplasty ring in mitral valve repair, in order to discuss the appropriate ring size. Methods Sixtysix patients (55 males,and 11 females with a mean age of 44.62±15.94 years) with mitral insufficiency underwent mitral valve repair with homemade flexible annuloplasty ring from April 2002 to November 2009 in Fu Wai Hospital. In order to choose the ring with an appropriate size, we made and kept to the following principles: if the intercommissural distance was bigger than size 30, we chose a ring 2size smaller; if the measured distance was smaller than size 30, 1size smaller ring would be chosen. Patients were followed by echocardiography to observe the mitral valve function. Results All patients were cured and discharged from the hospital. The results of echocardiography showed mild to moderate regurgitation in 1 patient, mild regurgitation in 11 patients, and normal mitral function or trace regurgitation in the rest 54 patients. Mitral valve forward velocity was 1.40±0.30 m/s with no mitral stenosis or systolic anterior motion (SAM) of the anterior mitral leaflet. Fiftyone patients were followed up from 2 months to 7 years(24.60±25.90 months). The results of echocardiography on 38 patients showed that 1 patient had moderate regurgitation, 5 patients had mild to moderate regurgitation, 9 patients had mild regurgitation and others had normal mitral function or trace regurgitation. For these 38 patients included in the followup study, mitral valve forward velocity was 1.50±0.40 m/s with no mitral stenosis, SAM or left ventricular outlet tract obstruction. During the followup, the left atrium size (43.19±10.48 mm vs. 48.59±9.40 mm, t=4.524, P=0.000) and left ventricular end diastolic diameter (52.64±7.35 mm vs. 6269±8.77 mm, t=7.607, P=0.000) decreased significantly than the preoperative size and diameter respectively.  The application of restrictive homemade flexible annuloplasty ring in mitral valve annuloplasty had satisfactory, durable and stable clinical results.

        • Surgical Repair of Functional Tricuspid Regurgitation: An Old Issue Revisited

          Abstract: Surgical repair of functional tricuspid regurgitation (FTR) is often carried out concomitantly with other leftsided heart valve procedures. Though diseases of both left heart valve and tricuspid were treated during the surgery, postoperative residual or recurrent tricuspid regurgitation has been clearly associated with progressive heart failure and worsened longterm survival. To date, surgical interventions mainly address FTR at three anatomic levels: commissure, annulus and leaflets. However, a certain mid and longterm failure rate after operation still exists. High surgical mortality rates have been reported in patients with recurrent tricuspid regurgitation requiring complex reoperations. With a better understanding of tricuspid anatomical complex and valvuloplasty, significant improvements have been made in FTR surgical indications and techniques. This review article will focus on the development of surgical indications in tricuspid valve repair, while the repair techniques and their impact on longterm clinical outcome will also be compared.

        • Valvoplasty in children

          Objective To evaluate the surgical characteristics, methods and clinical effect of pediatric valvoplasty through an analysis of valvoplasty in children in the age from 15 h to 14 years. Methods From January 1993 to June 2003, 376 children underwent valvoplasty. There were 349 cases (92.8%) of congenital heart disease and 27 cases(7.2%) of acquired heart disease. The procedure included mitral valvoplasty in 79 (19.4%), tricuspid valvoplasty in 159 (39.1%), aortic valvoplasty in 40 (9.8%), and pulmonary valvoplasty in 129(31.7%). Results There were 12 early deaths (3.2%) after the procedure. 297 patients were followed up from 1 month to 10 years (mean, 4.9±2.4 years). There were 2 late deaths (0.7%) after discharge. There were 5 cases (1.7%) of re-operation due to valve problem. Conclusions Valvoplasty should be the first choice in dealing with valve diseases in children. The effect of the valvoplasty works on the prognosis of the operation.

        • Prognosis and risk factors for mild to moderate or moderate atrioventricular valve regurgitation after Fontan operation

          ObjectiveTo investigate the prognosis and risk factors of mild to moderate or moderate atrioventricular valve regurgitation (AVVR) after Fontan operation.MethodsA total of 34 patients with mild to moderate or moderate AVVR who accepted Fontan operation and atrioventricular valve (AVV) repair between 2004 and 2018 in our center were selected as an AVV repair group. The patients in the same period were matched as a control group by the ratio of 1 : 1-2. Finally 99 patients were included into this study, including 64 males and 35 females, with an average age of 63.4±36.3 months and weight of 17.3±6.7 kg. Grades of AVVR decreased more than 1 was defined as significant improvement. Endpoints of the study were death, Fontan takedown, AVV replacement. Risk factors including Fontan procedures, AVV repair procedures, cardiac anatomy were analyzed.ResultsPatients were followed up for 1.5 (0.3-4.0) years. Overall mortality was 15.2%. Most (82.4%) of AVV repair group accepted single AVV repair procedure while partial annuloplasty was the most common (52.9%). With the extension of follow-up, the degree of AVVR in the whole group showed a gradually increasing trend (r=0.352, P=0.000). Mild to moderate AVVR improved spontaneously after Fontan operation, while moderate AVVR did not. AVV repair could improve the degree of AVVR after moderate regurgitation, without increasing the surgical mortality, and regurgitation significantly decreased in 8.8% patients. AVV repair was not effective for mild to moderate AVVR and would increase surgical mortality. ConclusionAVV function shows a gradual downward trend after Fontan operation. AVV repair is effective for moderate AVVR, does not increase mortality, but the degree of improvement is limited. AVV repair is not effective for mild to moderate AVVR and increases surgical mortality.
