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.
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.
ObjectiveTo compare the outcomes of repeated tricuspid valve surgery for patients with late severe tricuspid regurgitation (TR) after cardiac surgery through right anterior minithoracotomy and conventional median sternotomy approaches. MethodsBetween June 2002 and June 2013, 89 patients with late severe tricuspid regurgitation after cardiac surgery underwent repeated tricuspid valve surgery through right anterior minithoracotomy in our hospital. The patients were divided into two groups. Fifty one patients were in a minimally invasive group with 28 males and 23 females at age of 46.59±11.53 years. Thirty eight patients were in a conventional median sternotomy (conventional group) with 15 males and 23 females at age of 50.42±9.30 years. The outcomes of the two groups were compared. ResultsThere was no statisitcal difference in preoperative clinical data between two groups. All patients successfully underwent repeated tricuspid valve surgery. Tricuspid valve replacement (TVR) was performed in 68 patients (38 patients vs. 30 patients), and tricuspid valvuloplasty (TVP) was performed in 21 patients (13 patients vs. 8 patients). Compared with the conventional group, operation time, time of establishing cardiopulmonary bypass and postoperative in-hospital time were significantly shorter in the minimally invasive group (P<0.001). The postoperative drainage was significantly reduced in the minimally invasive group compared with the value of the conventional group (P<0.001). Three patients died in the early postoperative period (1 patient vs. 2 patients). In the conventional group, one patient needed re-exploration for bleeding and 2 patients had wound infection. At discharge, transthoracic echocardiography showed that all patients had no or mild TR and no paravalvular leakage occurred. During the follow-up (12-144 months), 4 patients died (2 patients vs. 2 patients). In the minimally invasive group, one patient underwent repeated TVR due to severe TR associated with infective endocarditis, and another patient had moderate TR. In the conventional group, one patient underwent repeated TVR due to mechanical valve thrombosis. ConclusionRight anterior minithoracotomy is safe, effective and reliable for patients with late severe TR after cardiac surgery. It has the similar effect of the correction of valvular lesions with conventional median sternotomy, but right anterior minithoracotomy has more benefits, including more, minimally invasive, less blood loss, shorter operation time and faster recover.
ObjectiveTo evaluate the clinical efficacy of tricuspid valve re-operation after left cardiac valve surgery. MethodsWe retrospectively analyzed the clinical data of 23 patients underwent tricuspid valve re-operation in the Affiliated Drum Tower Hospital of Medical School, Nanjing University from January 2009 to November 2014. There were 3 males and 20 females with a mean age 53.48±10.79 years ranging from 34 to 71 years. The average body mass index of the 23 patients was 21.77±2.42 kg/m2. We followed up all the patients in outpatient department or through telephone for 3 months to 5 years. ResultsAll surgeries were operated under cardiopulmonary bypass. There were 15 patients underwent operation through medisternal incision and 8 patients underwent operation through the fourth intercostal incision of right anterolateral side. The mean operation time was 284.35±56.16 minutes and the mean time of cardiopulmonary bypass was 138.61±46.91 minutes. One patient died postoperatively and 2 patients chose to discharge automatically after operation. The other 20 patients recovered and discharged uneventfully. We followed up the patients for 3 months to 5 years. One patient underwent permanent pacemaker therapy for atrioventricular block, 3 patients accepted pharmaceutical therapy for atrial arrhyttmia, 1 patient underwent re-operation for infectious endocarditis of left cardiac artificial valve. and the follow-up conditions of the rest patients were well. Besides, the follow-up data showed that there was a mild regurgitation in 3 patients underwent tricuspid valve plasty. ConclusionTricuspid valve re-operation after left cardiac valve surgery can take multiple surgical pathways and strategies. The clinical effect has been proved and the midterm follow-up condition is well, but we still need the long-term follow-up for the further effect.
