Association of edge-to-edge valve repair with artificial ring annuloplasty for severe tricuspid insufficiency

Objective To analyze whether association of edge to edge valve repair with artificial ring annuloplasty would result in better results in patients with severe tricuspid regurgitation (TR) . Methods From April,2001 to May, 2010,41 patients underwent tricuspid valve repair to treat severe TR were studied. Twenty-one patients were done artificial ring annuloplasty alone (group R) and twenty patients were done artificial ring annuloplasty associated with edge to edge valve repair (group E) . All the

Outcome of surgical treatment of post-traumatic tricuspid insufficiency

Objective： To investigate the optimal time and procedure of surgical treatment of traumatic tricuspid insufficiency. Methods： From May 1984 to September 2004, eight patients underwent operation for traumatic tricuspid valve insufficiency. All patients, male, aged from 7 to 67 years [ median： 38 years, mean： （ 38.5 ± 18. 1 ） years ]. The intervals between trauma and operation ranged from 1 month to 20 years [median： 19 months, mean： （52.5 ± 80.3） months） ]. In seven patients, tricuspid insufficiency was attributed to blunt chest trauma including vehicle accident in three patients and the other patient is a stab wound. Diagnosis was confirmed by echocardiography. Pre-operative cardiac functions in patients were classified as New York Heart Association （NYHA） classes Ⅱ-Ⅳ. During operation, the anterior leaflet of the tricuspid valve was completely or partially flailed as a result of chordal rupture in all patients. Chordal rupture of septal leaflet was found in one patient. Anterior leaflet was perforated in two patients. Septal leaflet was retracted and adherent to ventricular septum in two patients. Valve repair was intended for all patients. Finally, valve repair was performed successfully in 3 patients and tricuspid replacement was performed in 5 patients. Results： No early or late death occurred. With a follow-up through clinical manifestation and echocardiography for 7-129 months [median： 39 months, mean： （53.4 ± 42.8 ） months ], all patients were classified as NYHA class Ⅰ, without any changes. Conclusions： The satisfactory treatment of traumatic tricuspid insufficiency can be obtained by surgical treatment. Earlier surgery may increase the feasibility of tricuspid valve repair and prevent the deterioration of right ventricular function.

First-in-man Experience of a New Transcatheter Edge-to-edge Repair System Neoblazar in Patients With Severe Tricuspid Regurgitation

objective:Severe tricuspid regurgitation frequently leads to increased mortality and a poor prognosis.Transcatheter edge-to-edge repair(TEER)for tricuspid valve regurgitation has been reported as a safe alternative to traditional open-heart surgery.This study endeavors to assess the efficacy and safety of a newly designed Neoblazar TEER system in this high-risk population.Methods:This investigation was structured as a prospective,single-arm,first-in-man trial in China(ClinicalTrials.gov number:NCT05497141).From August 2022 to October 2022,patients with severe tricuspid regurgitation were enrolled from 3 centers(Xiamen Cardiovascular Hospital,Fuwai Yunnan Cardiovascular Hospital,and Wuhan Union Hospital).The primary endpoint was achieving a minimum 1-grade reduction in tricuspid regurgitation at the 6-month post-TEER intervention,in addition to the pertinent New York Heart Association class.Scheduled echocardiographic evaluations were conducted at the following distinct intervals:baseline,discharge,1 month,and 6 months post-TEER intervention.Results:A total of 10 patients were enrolled in the study.Immediately after the TEER procedure with the Neoblazar system,massive tricuspid regurgitation(grade 5+)at baseline decreased to moderate-severe tricuspid regurgitation(grade 3+)in 2 patients and the optimal tricuspid regurgitation reduction(severe tricuspid regurgitation(grade 4+)to mild tricuspid regurgitation(grade 1+)were achieved in 6 patients.After 6 months of follow-up,tricuspid regurgitation reduction was found to be durable in all enrolled patients,among whom at least 1 grade of tricuspid regurgitation reduction was sustained,even without reintervention.Consistently,the New York Heart Association class among these subjects significantly improved,with the percentage of patients categorized as class I-ll increasing from 0/10 at baseline to 5/10 after 1 month(P=0.015)and 8/10 after 6 months(P<0.001).Conclusion:Tricuspid TEER with the newly designed Neoblazar system appears to be a feasible and safe alternative in treating patients with severe tricuspid regurgitation.However,the implementation of larger and more robust randomized trials is still necessary for further verification of the potential benefits.

Diagnosed corrected transposition of great arteries after cesarean section:A case report

BACKGROUND Corrected transposition of the great arteries(cTGA) is a cardiac malformation in which the ventricular and arterial-ventricular positions in the heart are doubly reversed.In general,this defect puts a load on the systemic circulation and causes heart failure,resulting in a poor prognosis.This article reports a case of cTGA detected in a patient with post-caesarean pregnancy who had undergone elective caesarean section and was experiencing an episode of acute heart failure.CASE SUMMARY This was the case of a 36-year-old gravida 3 para 1 woman.No problems were noted in the puerperal course following the previous pregnancy.The current pregnancy was also uneventful.An elective caesarean section was performed and the patient was discharged from the hospital 7 d after the operation.On postoperative day 18,the patient became aware of breathing difficulty and presented at a nearby clinic,where she was referred to our institution after bilateral pleural effusions were detected.She was then diagnosed with acute heart failure after noting the presence of a prominent pedal oedema and SpO_(2) 91%(supine position and room air);the patient was promptly hospitalised for close examination and treatment.Although chest computed tomography revealed the presence of cTGA,no other cardiac malformations were observed.Owing to improvements in both the pedal oedema and pleural effusions,the patient was discharged on day 9.CONCLUSION Close examination should be performed on the premise of congenital cardiac malformation when heart failure symptoms are noted during perinatal control.

Diagnosis and treatment of traumatic tricuspid valve insufficiency

Traumatic tricuspid valve insufficiency (TTVI) is a relatively uncommon disease. To summarize the experience in the diagnosis and treatment of TTVI, we have analyzed the clinical data of 3 patients with TTVI who were admitted to the department of cardiac surgery of our hospital between April 1997 to April 2002. Relevant literatures have also been reviewed.
