ObjectiveTo analyze the mid-long-term outcomes of surgical balloon valvuloplasty (SBV) for right ventricular decompression in the treatment of pulmonary atresia with intact ventricular septum (PA/IVS).MethodsClinical data of consecutive 91 patients who were diagnosed with PA/IVS and underwent SBV in our institution from January 2005 to December 2017 were retrospectively analyzed, including 52 (57.1%) males and 39 (42.9%) females. The median age was 3 months (1 d, 24 months) and the median weight was 4.1 (2.5, 12.0) kg.ResultsThe SBV was performed in all patients, and 62 of whom received other simultaneous surgeries, including ligation of patent ductus arteriosus (PDA, 33 patients), ligation of PDA with modified Blalock-Taussig shunt (23 patients), ligation of PDA with bidirectional Glenn shunt (6 patients). There was no early postoperative death. The median follow-up time was 8.8 (2.5, 13.4) years, 4 patients were lost. There were 7 (8.0%) deaths and 1 (1.1%) patient with a re-SBV for pulmonary stenosis. The one and a half ventricular repair was performed in 5 (5.7%) patients and Fontan procedure in 2 (2.3%) patients. In addition, the mean Z-value of tricuspid valve annulus was −1.7±1.5, which was significant bigger than that before the operation (t=5.587, P<0.001).ConclusionSBV via right ventricular outflow tract for right ventricular decompression in the treatment of PA/IVS is safe and reliable. The majority of patients can receive biventricular repair instead of single ventricular palliation by SBV with individually customized shunt.
ObjectiveTo evaluate the effectiveness of mitral valve repair for mitral regurgitation. MethodsWe retrospectively analyzed the clinical data of 47 patients underwent mitral repair in General Hospital of Ningxia Medical University between January 2010 and June 2014 year. There were 36 males and 11 females with age of 10 months to 65 years, mean age of 42.38±15.27 years. ResultsThere was no operative death within follow-up time of 18±7 months (ranged 14 to 1 586 days). Mitral valve function was normal or traces regurgitation in 33 patients (70.21%). Mild mitral regurgitation occurred in 11 patients (23.40%). Postoperative transesophageal echocardiography showed that 2 patients (4.26%) had moderate regurgitation. They underwent mitral valve repair again and cured. One patient (2.13%) underwent mitral valve replacement because of moderate to severe regurgitation. The dimensions of left atrium and left ventricle obviously decreased and heart function improved significantly compared with preoperative ones. ConclusionStrict control of surgical indications for different valve disease, the use of mitral valve repair technique, mitral surgery can get a good clinical efficacy. Preoperative diagnosis by transesophageal echocardiography, intraoperative monitoring, and immediate postoperative assessment for mitral valve repair results provide good technical support.
Objective To investigate the efficacy of leaflet augmentation technique to repair the recurrent mitral valve (MV) regurgitation after mitral repair in children. Methods A retrospective analysis was conducted on the clinical data of children who underwent redo MV repair for recurrent regurgitation after initial MV repair, using a leaflet augmentation technique combined with a standardized repair strategy at Fuwai Hospital, Chinese Academy of Medical Sciences, from 2018 to 2022. The pathological features of the MV, key intraoperative procedures, and short- to mid-term follow-up outcomes were analyzed. Results A total of 24 patients (12 male, 12 female) were included, with a median age of 37.6 (range, 16.5–120.0) months. The mean interval from the initial surgery was (24.9±17.0) months. All children had severe mitral regurgitation preoperatively. The cardiopulmonary bypass time was (150.1±49.5) min, and the aortic cross-clamp time was (94.0±24.2) min. There were no early postoperative deaths. During a mean follow-up of (20.3±9.1) months, 3 (12.5%) patients developed moderate or severe mitral regurgitation (2 severe, 1 moderate). One (4.2%) patient died during follow-up, and one (4.2%) patient underwent a second MV reoperation. The left ventricular end-diastolic diameter was significantly reduced postoperatively compared to preoperatively [ (43.5±8.6) mm vs. (35.8±7.8)mm, P<0.001]. Conclusion The leaflet augmentation technique combined with a standardized repair strategy can achieve satisfactory short- to mid-term outcomes for the redo mitral repair after previous MV repair. It can be considered a safe and feasible technical option for cases with complex valvular lesions and severe pathological changes.
ObjectiveTo report the short-term outcomes of a standardized, simplified and reproducible strategy of mitral valvuloplasty (MVP), which was focused on leaflet foldoplasty and anatomic anomalies of congenital mitral regurgitation (MR).MethodsConsecutive 74 patients who underwent MVP by our standardized strategy in our institution from 2016 to 2018 were included retrospectively. There were 30 males and 44 females with a median age of 18.5 (6-146) months and weight of 15.4 (7-51) kg.ResultsAnatomic anomalies of MR included: (1) subvalvular apparatus: 72 (97.3%) patients with mal-connected chordae tendineae, 31 (41.9%) with absent chordae tendineae and 14 (18.9%) with fused or dysplastic papillary muscle; (2) leaflet: 10 (13.5%) patients with cleft of anterior leaflet, 61 (82.4%) with leaflet prolapse including 56 (91.8%) with anterior leaflet prolapse; (3) annulus: 71 (95.9%) patients with annular dilatation. Leaflet foldoplasty was performed in 61 (82.4%) patients with leaflet prolapse. All patients were successfully discharged and 4 (5.4%) patients were with moderate MR. The follow-up time was 22.0 (9.1-41.8) months. During the follow-up period, 3 patients had moderate MR and 1 patient had reoperation for severe MR. All patients were in normal cardiac function with a mean left ventricular ejection fraction of 66.0%±6.1%. In addition, the mean left ventricular end-diastolic dimension was 31.8±6.0 mm, which was significant smaller than that before the operation (t=6.090, P<0.000 1).ConclusionThe standardized leaflet foldoplasty with resection of mal-connected chordae tendineae and posterior annuloplasty technique is safe and feasible with favorable short-term outcomes in MR patients.

Objective To analyze the early prognosis of repairing adult aortic insufficiency with the Florida sleeve procedure. Methods The patients with aortic insufficiency who underwent Florida sleeve repair in the Nanjing First Hospital, Nanjing Medical University between August 2020 and May 2024 were selected. Their general data, perioperative conditions, and echocardiographic data before, during, and after the procedure and at follow-up were analyzed. Results Fifteen patients were included, consisting of 12 males and 3 females, aged 33-71 (53.5±12.4) years. Preoperative echocardiography indicated that there was 1 patient of rheumatic disease, 7 patients of degenerative disease, 4 patients secondary to aortic aneurysm, and 3 patients of bicuspid aortic valve. The severity distribution included 2 patients of severe insufficiency, 4 patients of moderate-to-severe insufficiency, 5 patients of moderate insufficiency, and 4 patients of mild-to-moderate insufficiency. The mean cardiopulmonary bypass time was (135.0±40.0) minutes, the aortic cross-clamp time was (109.9±38.6) minutes, and the median ICU stay was 1.0 day. No mortality was recorded within 30 days postoperatively. Follow-up echocardiography showed that the valve regurgitation, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and sinus diameter all achieved the desired outcomes. Conclusion Florida sleeve repair for aortic valve in patients with a sinus diameter less than 50 mm not only effectively improves hemodynamics in adults with aortic insufficiency, but also has the advantages of low surgical risk and rapid postoperative recovery, making it a promising procedure for clinical application.
ObjectiveTo analyze clinical outcomes of mitral valvuloplasty (MVP) via right anterolateral minithoracotomy. MethodsClinical data of 23 patients with valvular heart disease who underwent minimally invasive MVP via right anterolateral minithoracotomy from January 2011 to February 2013 in the Department of Cardiothoracic Surgery in our hospital were retrospectively analyzed. There were 8 males and 15 females with mean age of 41±10 years. The procedure was performed through a small (4-6 cm) incision via right anterolateral minithoracotomy. Cardiopulmonary bypass (CPB) was established via femoral artery and vein cannulation. Transthoracic clamp was used for ascending aortic clamping. Cold blood cardioplegia was delivered after aortic cross-clamping. Left atrial drainage was established through right superior pulmonary vein. MVP was performed through the atrial septal approach,and tricuspid valvuloplasty was performed for tricuspid regurgitation if necessary. ResultsAll the operations were successfully performed without in-hospital death. Operation duration was 160-290 (229±37) minutes. Aortic cross-clamping time was 40-121 (67±19) minutes. CPB duration was 60-136 (87±21) minutes. Postoperative mechanical ventilation time was 6-47 (16±11) hours. The length of intensive care unit stay was 19-60 (30±12) hours. Postoperative chest drainage was 80-780 (320±184) ml. Postoperative color Doppler echocardiography showed that left ventricular ejection fraction was 49%-65% (56.0%±4.8%). There were 5 patients with trivial mitrial valve regurgitation and 6 patients with mild tricuspid valve regurgitation. Postoperative mean length of the right thoracic incision was 3.9-6.0 (5.3±0.7) cm. The patients were followed up for 1-24 months. The result of echocardiography showed no modern to severe valve regurgitation. ConclusionMinimally invasive MVP via right anterolateral minithoracotomy is safe and feasible with satisfactory cosmetic and clinical results.
Nowadays, percutaneous pulmonary valve treatment is a hot topic in valvular heart disease, consisting of percutaneous balloon pulmonary valvuloplasty and percutaneous pulmonary valve implantation (PPVI). The percutaneous balloon pulmonary valvuloplasty is the prime intervention of pulmonary valve stenosis. The main indication of PPVI is pulmonary valve regurgitation and/or obstruction. PPVI is still the research focus, with the improvement of surgical indications and the development of surgical devices. However, compared with surgical pulmonary valve replacement, it still has limitations. This article reviews the treatment progress of percutaneous pulmonary valve treatment, especially PPVI.
Objective To evaluate the mid-long term results of application research of artificial Gore-Tex chordate in mitral valvuloplasty in patients with mitral insufficiency caused by endocarditis. Methods We retrospectively analyzed the clinical data of 28 consecutive infective endocarditis(IE) patients who received mitral valve repair with Gore-Tex in our hospital between January 2012 and December 2015. There were 17 males and 11 females. The age of these patients ranged from 18 to 69 (52.0±15.4) years. Echocardiography before operation showed the degree of mitral regurgitation (MR) was severe in 19 patients, moderate in 9 patients. Six patients were in New York Heart Association (NYHA) class Ⅱ, 14 in class Ⅲ, 8 in class Ⅳ. There were 26 selective surgeries and 2 emergent surgeries. One patient had concomitant coronary artery bypass graft. Six patients had aortic valve replacement. Five patients had aortic valve repair. Twenty patients had tricuspid valve repair. Five patients had Maze procedure. Results Follow-up was done to all the patients for 6 months to 55 (30.5±6.4) months. During the follow-up, the echocardiography showed that postoperative left atrium diameter (36.64±8.50 mm vs. 51.78±17.50 mm, P<0.05) and left ventricular end-diastolic dimension (49.30±5.05 mmvs. 57.70±7.49 mm, P<0.05) were significantly smaller than those before operation. The left ventricular ejection fraction (EF) increased from 53.86%±8.16% to 59.14%±4.23% (P<0.05). No MR was found in 16 patients, mild MR in 8 patients, mild to moderate MR in 2 patients, moderate MR in 1 patient. One patient required reoperation for recurrent infection. No death or complications related to thrombosis and embolism occurred after operation. Conclusion Application research of artificial Gore-Tex chordate in mitral valve repair is feasible for treating mitral valve lesions caused by endocarditis, and may provide a long-term outcome to the patients.
ObjectiveTo investigate clinical outcomes of mitral valvuloplasty (MVP)for the treatment of infective endocarditis (IE)and mitral regurgitation (MR). MethodsFrom March 2002 to January 2012, 33 patients with IE and MR underwent MVP in Fu Wai Hospital. There were 23 male and 10 female patients with their age of 10-67 (35.7±17.8)years. Thirteen patients had previous cardiac anomalies. Preoperatively, there were 5 patients with mild MR, 15 patients with moderate MR and 13 patients with severe MR. There were 5 patients in New York Heart Association (NYHA)functional classⅠ, 23 patients in classⅡ, 4 patients in classⅢ and 1 patient in classⅣ. All the patients received MVP including 14 patients received MVP in active phase of IE. Concomitantly, 6 patients received aortic valve replacement, 5 patients received tricuspid valvuloplasty, 1 patient received coronary artery bypass grafting, 1 patient received resection of left atrial myxoma and 1 patient received repair of aortic sinus aneurysm. Surgical procedures included pericardial patch closure of leaflet perforation in 5 patients, leaflet excision and suturing in 17 patients, double-orifice method in 3 patients, chordae transfer and artificial chordae implantation in 5 patients, and annuloplastic ring implantation in 15 patients. ResultsOne patient died of acute myocardial infarction 7 days after the operation. All other 32 patients were successfully discharged. Echocardiography before discharge showed left ventricular end-diastolic diameter (LVEDD, 48.9±7.6 mm)and left atrial diameter (LAD, 31.7±7.4 mm)were significantly smaller than preoperative values (P=0.000). Thirty-two patients were followed up for 6-125 (73.0±38.6)months. There was no death, IE recurrence, bleeding or thromboembolism during follow-up. One patient received mitral valve replacement for mitral stenosis 3 years after discharge. There were 25 patients in NYHA func-tional classⅠ, 5 patients in classⅡand 2 patients in classⅢ. There were 4 patients with mild MR, 1 patient with moderate MR, and 26 patients had no MR. One patient had faster mitral inflow at diastolic phase (1.7 m/s). One patient had moderate aortic regurgitation. LVEDD and LAD during follow-up were not statistically different from those before discharge. Left ventricular ejection fraction during follow-up was significantly higher than that before discharge (60.9%±6.6% vs. 57.5%±6.7%, P=0.043). ConclusionMVP is a reliable surgical procedure for patients with IE and MR, and can significantly reduce left atrial and left ventricular diameter and improve cardiac function postoperatively.
