ObjectiveTo investigate the therapeutic effect of modified tricuspid valvuloplasty using anterior leaflet in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia. MethodsNinety-five patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia underwent surgical treatment in our hospital from June 2002 to March 2014. There were 39 males and 56 females with an average age of 3.2±6.6 years (range 3 months to 46 years). Preoperative echocardiography prompted all patients had varying degrees of tricuspid valve dysplasia and tricuspid regurgitation (mild in 14 cases, moderate in 49 cases, and severe in 32 cases). According to the different development of anterior and septal leaflet, we used different techniques to repair the tricuspid problems. If the residual septal leaflet was larger than one third of the normal septal leaflet, we continuously stitched the half of the septal side of anterior leaflet to the two third of the left side of residual septal leaflet. If the residual septal leaflet was less than one third of the normal septal leaflet, we reserved part of pericardial patch at right side of septal crest at repairing the atrial septal defect, and continuously stitched the left two third of the patch edge to the half of septal side of anterior leaflet. All patients received transesophageal echocardiography (TEE) to evaluate the intraoperative effect of valvuloplasty. The patients were followed up with echocardiography after 3 to 6 months to evaluate the condition of tricuspid. ResultsThere was no perioperative death or Ⅲ degree atrioventricular block. Intraoperative TEE showed that the effect of tricuspid valvuloplasty was good with 3 cases of mild regurgitation and 2 cases of moderate regurgitation. Other 90 cases had no significant regurgitation. The aortic cross-clamping time was 35.2±11.2 min and cardiopulmonary bypass time was 64.9±16.6 min. In the followed-up between 3 to 6 months, tricuspid regurgitation situation improved significantly than that in preoperative period with mild regurgitation or no reflux in 89 cases and moderate regurgitation in 6 cases. There was no severe regurgitation occurred. ConclusionThe therapeutic effect is satisfactory by using anterior leaflet to repair the regurgitation of tricuspid in patients with partial antrioventricular septal defect and tricuspid septal leaflet dysplasia.
ObjectiveTo analyze the clinical efficacy of right minithoracotomy approach in the treatment of patients with regurgitation after left-sided valve surgery (LSVS).MethodsThe clinical data of 77 patients who suffered tricuspid regurgitation (TR) after LSVS and received surgical treatment in the Heart Center of Henan Provincial People's Hospital from 2012 to 2019 were selected. According to the operation method, the patients were divided into a right minithoracotomy group (n=32), including 13 (40.6%) males, aged 57.3±5.3 years and a median sternotomy group (n=45), including 17 (37.8%) males, aged 55.7±6.6 years. Preoperative and postoperative clinical data of the two groups were compared and analyzed.ResultsThere was no significant difference in preoperative data between the two groups. There were 24 patients of tricuspid valvuloplasty (TVP) and 8 patients of tricuspid valve replacement (TVR) in the right minithoracotomy group. There were 29 patients of TVP and 16 patients of TVR in the median sternotomy group. The operation time, postoperative hospitalization time, intubation time and ICU stay time of the right minithoracotomy group were shorter than those of the median sternotomy group (P<0.001). The operative bleeding, postoperative drainage in 24 hours, postoperative blood transfusion rate and incision poor healing of the right minithoracotomy group were significantly decreased compared with those of the median sternotomy group (P<0.05). The extracorporeal circulation time between the two groups was not significantly different (P=0.382). The postoperative complications and mortality of the righ minithoracotomy group were significantly lower than those of the median sternotomy group (P<0.05).ConclusionThe procedure of right minithoracotomy access can reduce perioperative morbidity and mortality compared with the median sternotomy, and results in satisfied clinical efficacy.
ObjectiveTo compare the efficacy of additional tricuspid valve annuloplasty (TVP) and isolated closure for atrial septal defect (ASD) with moderate to severe tricuspid regurgitation (TR). MethodsClinical data of the patients diagnosed with ASD combined with secondary moderate to severe TR and treated in our hospital from January 2009 to June 2020 were retrospectively analyzed. Patients were divided into a TVP group and a non-TVP group based on whether TVP was performed simultaneously. The baseline data of two groups were matched with a ratio of 1∶1 propensity score. ResultsA total of 32 pairs from 257 patients were successfully matched. In the TVP group, there were 24 females and 8 males with an average age of 44.0±13.1 years. In the non-TVP group, there were 28 females and 4 males with an average age of 44.5±11.6 years. The TR area and estimated pulmonary artery pressure in the two groups were significantly decreased compared with preoperation (all P<0.001). The TR area (P=0.001) and the estimated pulmonary artery pressure (P=0.002) were decreased more significantly in the TVP group than those in the non-TVP group. Linear regression analysis showed that age and preoperative TR area had a positive correlation with TR area at follow-up (β=0.045 and 0.259, respectively, both P<0.05), while additional TVP had a negative correlation (β=–1.542, P=0.001). ConclusionAdditional TVP can significantly reduce the TR area and pulmonary artery pressure, and elderly patients with severe TR before surgery should actively receive TVP.
Abstract： Objective To evaluate the surgical effect of ring annuloplasty using prosthetic vascular graft for the treatment of tricuspid regurgitation. Methods From July 2000 to July 2010, ring annuloplasty using prosthetic vascular graft was performed to a total of 56 patients with tricuspid regurgitation in Changhai Hospital of Second Military Medical University. There were 24 male patients and 32 female patients. Their mean age was（45.7±21.8）years (ranging from 14 to 73 years). All the patients were diagnosed as moderate to severe tricuspid regurgitation by color Doppler echocardiography examination, including 47 patients with rheumatic heart valve diseases, and 9 patients with congenital heart disease (Ebstein’s anomaly). All the 56 patients underwent ring annuloplasty using prosthetic vascular graft instead of Carpentier annuloplasty ring for the treatment of tricuspid regurgitation. Results There was no in-hospital death. Postoperatively, one patient had acute respiratory failure, one patient had acute kidney failure, and one patient had re-exploration for bleeding. All patients had none or mild tricuspid regurgitation by echocardiography examination one month after surgery. Forty eight patients were followed up from 1.0 to 9.5 years with a median follow-up time of 3.8 years. During follow-up, there was no late death, but one patient had brain embolism as an anticoagulation complication. Sixteen patients were in New York Heart Association (NYHA) functional classⅠ, 26 patients in NYHA classⅡ, and 6 patients in NYHA class Ⅲ. Thirty six patients had no tricuspid regurgitation, 10 patients had mild tricuspid regurgitation, and 2 patients had moderate tricuspid regurgitation by echocardiography examination during follow-up. Conclusion The early and mid-term follow-up results of ring annuloplasty using prosthetic vascular graft instead of Carpentier annuloplasty ring for the treatment of tricuspid regurgitation are satisfactory. It is a good choice for the surgical treatment of tricuspid regurgitation.
In historic perspectives, tricuspid valve was considered as “forgotten valve” in the cardiovascular field. Tricuspid regurgitation (TR) is the main disease of the tricuspid valve, and the number of patients is large. TR patients have mostly treated conservatively with drugs due to high surgical mortality, so the effective treatment of TR patients is far from satisfactory. With the development of interventional technology, transcatheter tricuspid valve intervention (TTVI) is expected to become a better choice. In recent years, a number of TTVI devices have entered clinical trials and achieved good results. Due to the late development of TTVI technology and insufficient accumulation of clinical applications, there are no uniform inclusion criteria and evaluation indicators for research endpoints when conducting clinical trials. This article focuses on the introduction of different instruments of TTVI, and summarizes the current status, research progress and problems of these treatments.
Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of re-operation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation.
