        • 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.

        • Evaluation of cardiac valve repair by 4D transesophageal echocardiography

          目的 探討四維經食管超聲心動圖(4D-TEE)在瓣膜修復中的作用。 方法 2016 年 1 月我院對 3 例行二尖瓣修復和 1 例行主動脈瓣膜修復的患者采用西門子 SC2000 4D-TEE 進行術前術后評估,其中男 2 例、女 2 例,年齡38~59 (48.0±10.5)歲。同期采用二維經食管超聲心動圖指導二尖瓣和主動脈瓣修復的 13 例患者作為對照,其中男 8 例、女 5 例,年齡43~67(56.4±7.5)歲。 結果 術中 4D-TEE 可實時顯示瓣葉的各項參數,如不同節段瓣葉高度、交界區面積、瓣葉面積、對合面的大小、竇管交界大小,瓣膜運動形態、主動脈管壁位移等信息。可根據內置軟件建立個性化的瓣膜幾何模型,動態模擬瓣膜啟閉并直觀呈現。對照組僅可顯示某切面的瓣膜、腱索、乳頭肌、心腔等信息。 結論 4D-TEE 跳過了對二維圖像的解讀步驟,更直觀完整地顯示了瓣膜形態和動態,可以通過它的輔助來進行更有效的手術決策。

        • 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.

        • 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.
