ABSTRACT
@#Objective 聽 聽To evaluate the mid-term outcomes between tricuspid valve detachment (TVD) and non-detachment (NTVD) for ventricular septal defect (VSD). Methods 聽 聽 The patients who underwent perimembranous VSD repair in the Department of Cardiovascular Surgery, West China Hospital from 2015 to 2020 were included. According to the surgical method, the patients were divided into a TVD group and a NTVD group. The clinical data of the two groups were compared. Results 聽 聽 Totally 538 patients were included in the study. There were 240 patients in the TVD group, including 121 males and 119 females, with an average age of 3.85卤8.42 years and an average weight of 14.12卤12.97 kg. There were 298 patients in the NTVD group, including 149 males and 149 females, with an average age of 4.42卤9.36 years and an average weight of 14.87卤12.51 kg. There was no statistical difference in the age, weight, sex, preoperative New York Heart Association (NYHA) classification or tricuspid regurgitation (TR) degree between the two groups (P>0.05). Median follow-up was 30 (23, 40) months in the TVD group, and 29 (23, 41) months in the NTVD group (P=0.600). After operation, one patient in each group developed third-degree atrioventricular block and recovered to sinus rhythm before discharge (P=0.848). No pacemaker was needed. There was no statistical difference in the length of stay (P=0.054), mortality (P=1.000), in-hospital reoperation (P=0.199), or follow-up reoperation (P=0.505). More than 98% of patients in both groups had postoperative TR less than moderate (P=0.926). At the last follow-up, only 7 (2.9%) patients in the TVD group were detected trivial residual shunting, and 14 (4.7%) in the NTVD group (P=0.289). No one needed to have reoperation because of residual VSD. The TVD group showed less TR during the follow-up (P=0.019). Conclusion TVD is an alternative technique which can be safely used in the closure of VSD, especially in technologically mature medical center. Appropriate tricuspid valve detachment for those hard-to-expose VSDs does not result in poorer tricuspid valve function or higher risk of atrioventricular block, and might reduce the incidence of residual shunting.
ABSTRACT
A 71-year-old woman underwent VVI pacemaker implantation for complete atrioventricular block 38 years ago at the cardiovascular department of another hospital. In the course of observation, she developed atrial fibrillation. One year ago, she was admitted to hospital for aggravated congestive heart failure and was subsequently treated by a cardiovascular practitioner. She had persistent shortness of breath and lower leg edema, which were treated with increasing doses of oral diuretics. Due to poor treatment outcomes, she was referred to our hospital. Her echocardiography results suggested severe tricuspid regurgitation (TR) and moderate mitral regurgitation. She was also found to have impaired renal function and liver cirrhosis (Stage A of the Child classification), and was admitted. In addition, she had undernutrition with suspected cardiac cachexia. She was first treated by inotrope infusion and central venous hyperalimentation before tricuspid annuloplasty and mitral valvuloplasty were performed. Even though her postoperative management was complicated, she was discharged from our hospital. The conservative treatment with the increased dose of the diuretic for TR-associated right heart failure was prolonged in this patient, leading to severe right heart failure and aggravation of impaired renal function or congestive liver-associated hepatic disorders. Eventually, the patient required operative intervention; however, postoperative management is usually complex, and the operation result may be poor in such patients. We suggest that, from the time when right heart failure can be managed with relatively small doses of diuretics, surgeons should be involved in the care of patients with severe TR who do not require left heart valvular surgery, and should discuss the necessity of surgery earlier than the relevant guidelines suggest, depending on the patient's condition.
ABSTRACT
Objective:To explore the value of transesophageal echocardiography(TEE) guidance for transcatheter DragonFly? system edge-to-edge tricuspid regurgitation (TR) repair.Methods:Five cases who were chosen in the Second Affiliated Hospital, Zhejiang University School of Medicine from December 2020 to January 2021 with surgical high-risk and severe functional TR underwent transcatheter DragonFly edge-to-edge repair with the guidance of TEE. Preoperative TEE was used to evaluate the tricuspid valve anatomy and the origin and etiology of regurgitation in detail; intra-procedure guidance of TEE was performed during the DragonFly system for tricuspid valve edge-to-edge repair intervention and after release of the DragonFly clip, the effect of surgery was assessed immediately and compared with pre-procedure TEE.Results:A total of 10 DragonFly clips were implanted in 5 patients (3 in each of patients, 2 in 1 patient, and 1 in each of patients). One of the 3 clips in 1 patient fell off unilaterally from the septal valve after release, and the other 9 clips were well positioned and fixed. Immediately post-operation assessment by TEE depicted the TR in 3 patients declined to mild and 2 to moderate. The vena contracta area by using three-dimensional color blood flow quantitative assessment was reduced[(0.93±0.26)cm 2 vs (0.20±0.11)cm 2]. No complications such as serious tricuspid valve injury, pericardial tamponade, thromboembolism occurred in the 5 patients. Conclusions:TEE plays an important role in guiding and monitoring transcatheter DragonFly system edge-to-edge TR repair during the entire procedure.
ABSTRACT
@#Recently, several transcatheter devices for aortic valve replacement and mitral valve repair have been used in clinic, and researchers have designed a variety of tricuspid valve (TV) intervention devices. We reviewed the current status of transcatheter TV intervention, and focused on the structures of these devices and the early results of clinical trials. Undoubtedly, transcatheter intervention for TV is promising, innovational and safe for patients with severe TV regurgitation.
ABSTRACT
PURPOSE: Significant late-onset tricuspid regurgitation (TR) is unfortunately common after double valve replacement (DVR); however, its underlying factors remain undefined. We evaluated the effect of aortic patient-prosthesis mismatch (PPM) on late-onset TR and clinical outcomes after DVR. MATERIALS AND METHODS: Of the 2392 consecutive patients who underwent aortic valve replacement between January 1990 and May 2014 at our institution, we retrospectively studied 462 patients who underwent DVR (excluding concomitant tricuspid valvular annuloplasty or replacement). Survival and freedom from grade >3 TR were compared between PPM (n=152) and non-PPM (n=310) groups using the Kaplan-Meier method. RESULTS: Although the overall survival rates were similar between the two groups at 5 and 10 years (95%, 91% vs. 96%, 93%, p=0.412), grade >3 TR-free survival was significantly lower in the PPM group (98%, 91% vs. 99%, 95%, p=0.014). Small body-surface area, atrial fibrillation, PPM, and subaortic pannus were risk factors for TR progression. However, aortic prosthesis size and trans-valvular pressure gradient were not significant factors for either TR progression or overall survival. CONCLUSION: Aortic PPM in DVR, regardless of mitral prosthesis size, was associated with late TR progression, but was not significantly correlated with overall survival. Therefore, we recommend careful echocardiographic follow-up for the early detection of TR progression in patients with aortic PPM in DVR.

A 28-year-old man was involved in a traffic accident that sandwiched his chest between a wall and a truck. Shortness of breath and other symptoms started to appear several years later. Echocardiography at that time showed severe tricuspid regurgitation due to a failed valve and ruptured chordae in the anterior leaflet. He was followed up with medication. Leg edema developed at the age of 62 years and worsening symptoms of heart failure over a period of 6 months indicated a need for surgery. Intraoperative findings revealed the ruptured chordae attached to the anterior leaflet and a scarred myocardium at the septomarginal trabeculation. The tricuspid valve was surgically repaired, the anterior leaflet chordae were surgically reconstructed, an annuloplasty ring was implanted to address the tricuspid regurgitation and atrial fibrillation was treated using the Maze procedure. Surgery 34 years after trauma has improved hemodynamic cardiac function and normalized the cardiac rhythm in this patient.
ABSTRACT
Transvenous pacemaker leads may impair tricuspid valve coaptation, and is a well-known cause of tricuspid regurgitation (TR). The mechanism underlying TR may be the perforation or laceration of the valve leaflets, direct lead interference with the valve closure, or adhesion of scar tissue between the leads of the pacemaker and the valve leaflet. Recently, three-dimensional echocardiography has clarified the pathway of the pacing lead and its interference with the tricuspid valve, but surgical treatment is not conventionally performed in the early stages of TR because of the necessity of the pacing lead. Occasionally, patients with TR develop severe right-sided heart failure, and the operative mortality in such conditions is very high. Thus, it is important to study the relationship between transvenous leads and TR. Tricuspid valve surgery is usually performed after replacing the transvenous lead with an epicardial lead. However removal of the transvenous lead may cause injury to the right ventricle, and ventricular chronic stimulation thresholds with epicardial stimulation have been shown to be significantly higher than those with endocardial stimulation. We performed TR surgery in 5 patients without removing the transvenous leads. To avoid interference with the valve closure, we shifted the pacemaker leads to the commissure and fixed them to the annulus. All the patients underwent successful tricuspid valve repair or replacement, and the symptoms of right-sided heart failure improved after the operation. We concluded that this technique is a very simple, and feasible method for treatment of most patients with TR caused by pacing leads.
ABSTRACT
Objective To compare the mid- and long-term results of tricuspid valve (TV) repair with or without an annuloplasty ring. Methods Two hundred seventy-seven patients underwent TV repair at our division (Sep. 2001 to Sep. 2008) ,of which 203 had, predominantly, a De Vega or Kay procedure (non-ring group) and 74had an annuloplasty with an artificial ring (ring group). TV pathology mainly was functional (secondary) and several with rheumatic leaflets involvement. Concomitant procedures consisted of mitral valve surgery in all patients,aortic valve surgery in 81 ,and coronary bypass in 19. Clinical and echocardiographic data followed for 1.5 to 3.5years were obtained. Results Postoperationally,the mid-term(1.5 years) follow-up was 100% completed and the long-term follow-up for 3. 5 years was 89. 9%. The recurrence of TV regurgitation (TR) of moderate and lower degree was not significantly different(χ2 = 1.3128, P= 0.26) in the 1.5 years follow-up between the two group,whereas the recurrence of TR of moderate to severity degree was significantly less in the ring group (χ2 =5. 8159,P =0.023).In the long term follow up,the TR in the ring group (25%) was significantly lower than that of 15% in the non-ring group (χ2 = 4. 9328, P = 0.036) . There are higher proportion of patients developing to moderate TR in the non ring group(34%) than in the ring group (10%) (χ2 =7. 9120,P =0.005). The TR developed fast in the ring group,increasing from 18% at 1.5 years follow up to 10% at 3.5 years follow up (χ2 = 2. 1327, P = 0.016),whereas it was relatively stable in the non-ring group,with 7% at 1.5 year follow up and 10% at 3.5 year follow up. Conclusions Placement of an annuloplasty ring in patients undergoing TV repair could remarkably improved the mid and long terum outcome. In clinic practice, we should be more positive to the functional TR and prefer to the procedure with annuloplasty ring.
ABSTRACT
Objective Tricuspid regurgitation is often associated in patients with congenital heart disease. Significant morbidity and mortality are related to tricuspid valve replacement. Tricuspid valve plasty is still a preferred choice. This report deals with our surgical experience in using edge-to-edge valve plasty technique to correct severe tricuspid regurgitation in patients with congenital heart disease. Methods From April 2001 to Mar. 2010, severe tricuspid regurgitation was corrected with a flexible band anuloplasty and edge-to-edge valve plasty technique in 14 patients with congenital heart disease. The age ranged from 7 years to 62 years [average (31.2 ± 16.1 ) years]. Congenital cardiac anomalies include: atrioventricular canal in 5 cases, secundum atrial septal defect in 6 cases, secundum atrial septal defect with mitral valve regurgitation in 2 cases and cor triatriatum in 1 case. Results No hospital death or postoperative morbidity occurred. No or trivial tricuspid regurgitation was present in 11 cases and mild tricuspid regurgitation in 3 cases at discharge. The follow-up ranged from 3 month to 97 months [average (51.6 ± 26.8 ) months]. No tricuspid stenosis was found. No or trivial tricuspid regurgitation was present in 5 cases. Mild tricuspid regurgitation was present in 8 cases, and moderate tricuspid regurgitation in 1 case at the latest followup. Conclusion Edge-to-edge valve plasty is an easy, effective and important procedure to correct severe tricuspid regurgitation in patients with congenital heart disease.
ABSTRACT
Although very rare, the incidence of tricuspid valve regurgitation after blunt chest trauma has risen in line with the increasing rate of car accidents and steering wheel trauma. It is easy to miss the diagnosis of tricuspid valve regurgitation following blunt chest trauma because most patients feel no symptoms at trauma, and the condition is sometimes overlooked for a long period of time due to its mild symptoms. A 49-year-old man suffered dyspnea on exertion for 1 month due to right heart failure 8 years after accidentally falling from a third floor. Preoperative echocardiography revealed severe tricuspid valve regurgitation resulting from prolapse of the anterior leaflet with annular dilatation. The patient underwent tricuspid valvuloplasty with a 36-mm Carpentier tricuspid ring. Intraoperative transesophageal echocardiography showed mild tricuspid valve regurgitation. We report a case of successful native valve salvage of ruptured tricuspid valve after blunt chest trauma, and present a review of the relevant literature.
