ABSTRACT

Objective:To confirm the safety and feasibility of totally thoracoscopic repair with leaflet folding, multiple artificial chordae implantation and ring annuloplasty for mitral regurgitation(MR) in Barlow disease.Methods:From June 2018 to December 2019, 10 consecutive Barlow’s disease patients underwent totally thoracoscopic repair with leaflet folding, multiple artificial chordae implantation and ring annuloplasty. The safety and feasibility of this technique was evaluated by its early clinical outcomes.Results:8 males and 2 females. The mean age was(33.5±11.0) years.There was no operative death and related complications. The mean cardiopulmonary bypass(CPB) time was(142±26)(112-194)min, and the aortic clamping time was(96±18)(78-128) min. The average number of artificial chordae implantation was(3.4±0.7)(2-4) pairs/case. Intraoperative transesophageal echocardiography(TEE) showed the mean mitral valve coaptation length and transvalvular pressure gradient was(1.2±0.2)(0.8-1.5) cm and(1.2±0.4) mmHg(1 mmHg=0.133 kPa), respectively, without MR or systolic anterior motion(SAM). During a follow-up of 1-18 months, there were 7 cases with no MR and 3 with trace MR, with a mean transvalvular pressure gradient of( 1.5±0.6 )mmHg.Conclusion:Totally thoracoscopic repair with leaflet folding, multiple artificial chordae implantation and ring annuloplasty was a safe and effective procedure with satisfied early clinical outcomes for MR in Barlow’s disease. However, further randomized and long-term follow-up studies were warranted to determine its clinical effects.

ABSTRACT

Objective:Reported our experience of 100 consecutive cases of thoracoscopic mitral valvuloplasty in the early period.Methods:Between September 2017 and December 2019, 100 consecutive cases of thoracoscopic mitral valvuloplasty had been completed in our institution. There were 56 males and 44 females. The mean age was(49.2±14.7) years old, ranging from 15 to 75 years old.The safety and feasibility of this technique was evaluated by its early clinical outcomes.Results:Mitral valve(MV) repair techniques included leaflet folding in 5 cases, cleft suture in 10, commissuroplasty in 15, edge to edge in 1, artificial chordae implantation in 76 cases with mean of(2.5±1.6)(1-4) pairs, and prosthetic annuloplasty in all cases. Intraoperative transoesophageal echocardiography(TEE) revealed no mitral regurgitation(MR) in 95 cases and a mild in 2 cases with all coaptation length more than 5 mm. The rest 3 cases with moderate or more MR were successfully reconstructed after being blocked again. The mean cardiopulmonary bypass(CPB) time was(164.4±51.0 )min and aortic clamping time was(119.7 ± 39.1) min, and the latest 10 cases were(140.2±45.3 )min and(96.3±25.4) min, the difference was statistically significant( P<0.05). There was one operative death for avulsion of left atrial suture after operation and 2 intraoperative re-exploration for bleeding. Severe MR was observed in 2 patients 3 months after operation, and mitral valve replacement(MVR) was performed through median sternotomy. Conclusion:Totally thoracoscopic mitral valvuloplasty is technically feasible, safe, effective and reproducible in clinical practice after crossing the learning curve. The short-term effect is satisfactory, however, further randomized and long-term follow-up studies are warranted to determine its clinical effects.

ABSTRACT

Objective@#To examine minimally invasive tricuspid valve operations applied in tricuspid valve insufficiency patients with previous left-sided valve surgery.@*Methods@#Between September 2017 and June 2019, thirty-six consecutive patients received minimally invasive totally thoracoscopic tricuspid surgery through right thoracotomy at Department of Cardiovascular Surgery, Fisrt Medical Center, People′s Liberation Army General Hospital. There were 13 males and 23 females, aging (56±11) years (range: 43 to 79 years). All the patients had isolated significant tricuspid regurgitation after previous left-sided cardiac surgeries. A right anterolateral thoracotomy incision about 4 cm was made from the fourth intercostal space as main operating port. The arterial cannula was placed in femoral artery. The venous cannula was placed in femoral vein using Seldingger technique. Tricuspid valve operation was performed on beating heart by assist of vena vacuum.@*Results@#Tricuspid valve repair was performed in 7 patients. Tricuspid valve replacement with bioprosthesis was performed in 29 patients. The operation time was (2.9±0.3) hours (range:2.5 to 3.6 hours). There was no conversion to sternotomy during operation. There was no severe complications during operation period. There were no complications related to this cannulation technique. The time of cardiopulmonary bypass establishment was (22±5) minutes (range: 12 to 24 minutes) and pump time was (82±16) minutes (range: 62 to 93 minutes). The length of hospital stay was (9±3) days after operation (range: 5 to 13 days). There was no early death in hospital. All patients were followed up for 3 to 22 months. No patient died.@*Conclusions@#One single port-based minimally invasive approach seems to be safe, feasible, and reproducible in case of redo tricuspid valve operations. Only cannulation of inferior vena cava significantly simplified the complexity of isolated redo tricuspid surgery.

ABSTRACT

Behcet's disease with aortic regurgitation as its initial or prominent manifestation is relatively rare. The prognosis of these patients is poor and the death rate is high. Perivalvular leakage and pseudoaneurysm often occur after surgery due to clinicians failed to diagnose Behcet's disease before surgery . At present, the etiology of the disease is not clear , and there is lack of experience and consensus in drug control, selection of operation timing and methods, or prediction of postoperative complications. This review summarizes the pathophysiological changes, clinical manifestations, diagnosis and treatment methods and prognosis of the disease, with a view to improve the level of cognition and treatment of this disease and improving the quality of life of patients.
