Objective To evaluate the effect of treating Ebstein ’s anomaly w ith tricuspid valve replacement (TVR), and analyze the indications and personali ze the surgical methods of TVR. Methods 35 TVR in 32 cases of Eb stein’s anomaly not amenable to repair from May 1993 to June 2007 in An zhen Hospital were retrospectively. The mortality and complication incidence wer e estimat ed and the KaplanMeier survival curves were constructed to estimate actual sur vival and freedom from thrombus embolism rate, and comparative studies were unde rtaken to e valuate the clinical effect between implanting the prosthesis in the original tr icu spid ring or above the coronary sinus, and between fold the atrialized ventricle or not, and between preserve the autologous tricuspid or not. The univariate an alysis and logistic regression were used to explore the early and late death ris k factors. Results There were 2 early hospital death (6.25%). Followup of 30 patients who survived 30 days ra nged up to 14 years (4.2±3.5years),there were 3 TVR reoperation due to the pro sthesis deterioration. There were 2 late deaths(6.67%), and the actuarial surv i val at 5,10 year was 92.1%±4.6%, 86.5%±5.8% respectively in KaplanMeier cu rve. There were 2 events of thrombus embolism that were cured through thromboly tic therapy, thus the freedom from thrombus embolism at 5 and 10 yers reached 91 . 3%±4.5%,82.3%±4.2% respectively. 24 late survivors were in New York Heart Ass ociation(NYHA) functional cl ass I, and 4 in NYHA functional class II. The incidence of atria ventricular nod e rhythm in patients with the prosthesis implanted in original tricuspid ring wa s statistically higher than that of prosthesis implanted above the coronary sinus,and the incidence of paradoxical ventricular septal motion in patients wi thout folding the atrialized ventricle was statistically higher that of with fol ding the atrialized ventricle, but the NYHA functional class was not affected by these factors.The univariate analysis and logistic regres sion revealed that preoperative functional right ventricle/atrialized ventriclelt; 1 and ascites were the independent risk factor for the early death (P=0.023, 0.025), whereas preoperative ascites and edema in lower extremities were the in dependent risk factors for late death (P=0.026, 0.019). Conclusion TVR is a good therapeutically option for Ebstein’s anomaly si nce the operative risk is low, the functional status improved in all patients an d the durability of prosthesis in tricuspid position has been good. In order to maximize the effect of the TVR in Ebstein’s anomaly, personalized procedure sho uld be adopted in deciding whether to fold the atrialized ventricle or not, to p reserve the autologous tricuspid valve or not, and to implant the prosthesis in the original tricuspid ring or above the coronary sinus.
Abstract: Objective To summarize the clinical experience of 13 patients of tricuspid valve replacement and to investigate the indication and method. Methods From January 1994 to December 2005, the clinical datum of the thirteen patients suffering from tricuspid valve disease were reviewed, including rheumatic heart disease 6 cases, congenital heart disease 3 cases, infective endocarditis 3 cases and right ventricular tumor 1 case. All the cases underwent tricuspid valve replacement. Results Two reoperative rheumatic heart disease patients died early after operation and their cardiac function was New York Heart Association (NYHA) class Ⅳ before operation. The followup interval was 3 months to 12 years in 11 cases. There were 2 late death, one died of recurrence of infective endocarditis, and another died of the recurrence of the tumor. One Ebstein anomaly case’s NYHA functional recovered to class Ⅲ, eight cases’s recovered to NYHA classⅠ-Ⅱ. Conclusion The tricuspid valve disease may be a secondary lesion from many causes. Indication of tricuspid valve replacement must be strictly commanded. The late results of tricuspid valve mechanical prostheses replacement is satisfactory.
ObjectiveTo investigate the indications and clinical effects of tricuspid cone reconstruction and tricuspid valve replacement in the treatment of downward displacement of tricuspid valve (Ebstein anomaly).MethodsThe clinical data of 22 patients with Ebstein anomaly who underwent surgical treatment in our hospital from January 2013 to March 2020 were collected. There were 7 males and 15 females, aged 4-56 (33.68±17.78) years. The patients were divided into two groups according to different surgical methods: a tricuspid cone reconstruction group (tricuspid valvuloplasty group, n=12) and a tricuspid valve replacement group (n=10). The curative effect of the two operative methods were compared.ResultsTwenty-two patients underwent surgical treatment under general anesthesia and cardiopulmonary bypass. One patient died of severe low cardiac output syndrome during operation. Downward displacement of tricuspid septum was found in 22 patients, and downward displacement of tricuspid septum and posterior septum in 21 patients, downward displacement of tricuspid in 8 patients. Twelve patients were treated with tricuspid valvuloplasty, 10 patients with tricuspid valve replacement, and patients with other intracardiac structural malformations were treated at the same time. Postoperative cardiac doppler ultrasound indicated no tricuspid regurgitation in 9 patients, mild regurgitation in 8 patients, and moderate regurgitation in 4 patients. No perivalvular leakage occurred in all patients undergoing valve replacement. Four patients developed degree Ⅲ atrioventricular block after operation, among whom 3 patients recovered to sinus rhythm and 1 patient implanted the permanent pacemaker. Twenty-one patients were cured and discharged after successful operation, and were followed up for 3 to 78 months, with a follow-up rate of 100.0%. During the follow-up period, there was no severe tricuspid regurgitation in tricuspid valvuloplasty group, but mild or moderate regurgitation was found. After tricuspid valve replacement, only 1 patient had mild regurgitation, and the rest patients had no valve regurgitation.ConclusionTricuspid valvuloplasty and tricuspid valve replacement are effective in the treatment of Ebstein anomaly, and the tricuspid regurgitation is less severe after tricuspid valve replacement operation. The operation method should be selected according to the different anatomical characteristics and condition of tricuspid valve. The combined intracardiac malformation or arrhythmia can be dealt with simultaneously.
ObjectiveTo evaluate the long-term clinical effect and risk factors of tricuspid valve replacement (TVR) as a relief treatment for adult patients with congenitally corrected transposition of the great artery (CCTGA).Method We retrospectively analyzed the clinical data of 47 adult patients with CCTGA who underwent tricuspid valve replacement in Fuwai Hospital between 2000 and 2017 year. There were 27 males and 20 females with operation age of 14–62 (38.8±13.5) years. Preoperative echocardiography showed moderate or more tricuspid regurgitation in all patients. The basic data of patients before and during operation were recorded. Survival was followed up by telephone and ultrasound report.ResultsThe average follow-up time was 6.5±3.7 years. The 1-year, 5-year and 10-year survival rate or the incidence of heart transplant-free was 94.6%, 90.5% and 61.7%, respectively. During the follow-up period, the long-term right ventricular ejection fraction of most patients (>90%) was still greater than or equal to 40%. Increased preoperative right ventricular end diastolic diameter (RVEDD) was a risk factor for death or heart transplantation (risk ratio 1∶11, P=0.04). The survival rate of patients with RVEDD (>60 mm) before operation was significantly reduced (P=0.032).ConclusionTVP is a feasible treatment for adult patients with CCTGA. The increase of preoperative RVEDD is a risk factor for long-term mortality.
Objective To investigate the surgical indications and the mid and long term results of morphologic tricuspid valve replacement for corrected transposition of the great arteries(cTGA). Methods From September 1997 to September 2007, 18 cases with cTGA were treated in Fu Wai Hospital. There were 15 male and 3 female, aged from 16 to 51 years(33.3±12.8 years), and weighed from 47 to 90 kg(60.9±14.7 kg). There were 10 cases with isolated morphologic tricuspid valve insufficiency, 3 complicated with ventricular septal defect, 2 complicated with ventricular septal defect and pulmonary valve stenosis, 2 with morphologic tricuspid valve insufficiency after septal defect repair, and 1 with mechanical valve dysfunction after morphologic tricuspid valve replacement. The preoperative mean morphologic right ventricle ejection fraction was 562%±11.6%. Of the 18 cases, 12 were in grade Ⅱ and 6 were in grade Ⅲ according to New York Heart classification(NYHA).All the cases had undergone morphologic tricuspid valve replacement. Postoperative indices such as cardiac function and morphological right ventricle ejection fraction were followed up. Results One patient died of postoperative low cardiac output syndrome. Two had pervavlvular leak, which were cured by pervavlvular leak repair at 7th and 30th day after operation, respectively. Sixteen were followed up with a followup time of 57.0±407 months. There was no statistical significance between preoperative and postoperative mean morphologic right ventricle ejection fraction(52.8%±9.2% vs.56.2%±11.6%; t=2.062, Pgt;0.05). The followup showed that 12 were in NYHA grade Ⅰ or Ⅱ, and 4 were in NYHA grade Ⅲ. There was no statistical significance between preoperative and postoperative percentage of cases in NYHA grade Ⅲ(χ2=1.532,Pgt;0.05). Conclusion Morphologic tricuspid valve replacement can prevent the further damage to morphologic right ventricular function caused by morphologic tricuspid valve insufficiency. The mid and long term results were satisfying. During the followup, the morphologic right ventricle can function appropriately.
Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
