Objective To retrospectively review the clinical experience and early surgical results of combined cardiac valve surgery and coronary artery bypass grafting （CABG）. Methods From Jan. 2000 to Dec. 2005, combined valve surgery and CABG was performed in 81 patients. 37 patients were rheumatic heart disease with coronary stenosis, and 44 patients were coronary artery disease with valvular dysfunction. Single vessel disease was in 18 patients, two vessels disease in 9 and triple-vessel disease in 54. All the patients received sternotomy and combined valve surgery and CABG under cardiopulmonary bypass. Mitral valve repair and CABG were done in 26 patients. Valve replacement and CABG were done in 55 patients with 49 mechanical valves and 16 tissue valves. Four patients had left ventricular aneurysm resection concomitantly. The number of distal anastomosis was 3.12 5= 1.51 with 66 left internal mammary arteries bypassed to left anterior descending. Post-operative intra-aortic balloon pump was required in 4 cases for low cardiac output syndrome. Results Two patients died of low cardiac output syndrome with multiple organs failure. 79 patients had smooth recovery and discharged from hospital with improved heart function. 64 patients had completed follow-up with 5 late non cardiac related death in a mean follow-up period of 14.2 months. Conclusion Combined one stage valve surgery and CABG is effective with acceptable morbidity and mortality.
Abstract： Objective To evaluate the early and late results of mitral valve replacement with home made C-L pugesturt tilting disc and analyse the factors which impact on the therapeutic effect，so as to elevate the operative effect. Methods A retrospective study was made on the result of clinical data and longterm followup of 259 patients who had undergone the Chinesemade C-L pugesturt tilting disc mechanical valve replacement from October 1991 to November 2006. Results The data showed that there were 12 patients died in the duration of hospital stay.The hospital mortality was 4.63% (12/259).There were no mechanical valverelated complication in the earlier postoperative period.The mortality fell to 2.59% since 1996.Among the 235 patients,12 patients were lost during the followup,the rate of followup was 95.1%(235/247).The time for followup was 9.77±3.09 years. There were 26 late deaths.During the follow-up,death associated with the deterioration of valve structure were not observed. The 5 years, 10 years and l5 years survival rates were 86.80%±2.30%, 78.20%±3.33% and 55.23%±4.34% respectively; the thromboembolic event free rates for 5 years, 10 years and l5 years were 95.95%±0.74%, 92.52%±4.11% and 80.52%±4.11% respectively; the anticoagulant related bleeding free rates for 5 years, 10 years and l5 years were 94.64%±1.75%, 89.55%±3.28% and 79.39%±4.43% respectively.There were 141 patients(67.46%) in New York Heart Association(NYHA) classⅠ, 56 patients(26.79%) in class Ⅱ, 10 patients(4.78%) in class Ⅲ and 2 patients(0.95%) in class Ⅳ. Conclusion The results of follow-up for 15 years suggest that the Chinesemade C-L pugesturt tilting disc medical mechanical valve is a reliable and safe choice for mitral valve replacement.
Technical advances both in cardiac surgery and relating to anesthesia,cardiopulmonary bypass and myocardial protection have significantly improved the prognosis for patients combined with coronary heart disease and heart valve disease. In addition to technology, variable factors that affect operative survival following combined operation include the severity of valvular disease, the number of coronary vessels affected, impairment of left ventricular function and both age and gender differences. In this article, we review the outcome of surgical intervention for heart valve disease combined with coronary heart disease and discuss future prospects in this field.
Abstract: Objective To summarize the clinical experience of 13 patients of tricuspid valve replacement and to investigate the indication and method. Methods From January 1994 to December 2005, the clinical datum of the thirteen patients suffering from tricuspid valve disease were reviewed, including rheumatic heart disease 6 cases, congenital heart disease 3 cases, infective endocarditis 3 cases and right ventricular tumor 1 case. All the cases underwent tricuspid valve replacement. Results Two reoperative rheumatic heart disease patients died early after operation and their cardiac function was New York Heart Association (NYHA) class Ⅳ before operation. The followup interval was 3 months to 12 years in 11 cases. There were 2 late death, one died of recurrence of infective endocarditis, and another died of the recurrence of the tumor. One Ebstein anomaly case’s NYHA functional recovered to class Ⅲ, eight cases’s recovered to NYHA classⅠ-Ⅱ. Conclusion The tricuspid valve disease may be a secondary lesion from many causes. Indication of tricuspid valve replacement must be strictly commanded. The late results of tricuspid valve mechanical prostheses replacement is satisfactory.
Objective To observe the midterm haemodynamic manifestation of the home made C-L pugestrut tilting disc mechanical valve in aortic valve replacement, and to evaluate its function. Methods Twenty patients underwent aortic valve replacement over 5 years were collected and divided into two groups, the C-L pugestrut group （n=10）：aortic valve was replaced by home-made C-L pugestrut tilting disc mechanical valve（21mm）; Medtronic-Hall group （n=10）：aortic valve was replaced by Medtronic-Hall mechanical valve （21mm）. The peak transprosthetic gradients （△P）, mean transprosthetic gradients （△Pm）and effective orifice area（EOA） at rest were compared between two groups. Results At rest, △P of the C-L pugestrut group and Medtronic-Hall group were 11.63±3.23mmHg vs. 9. 78±3. 35mmHg; △Pm of the C-L pugestrut group and Medtronic-Hall group were 6. 25±2. 32 mmHg vs. 5.85±2.32mmHg： EOA of the C-L pugestrut group and Medtronic-Hall group were 1.07±0.17 cm2 vs. 1.25±0.27 cm2. There was no statistically significance in △P, △Pm and EOA between two groups（P〉0.05）. Conclusions The midterm haemodynamic results of the home-made C-L pugestrut tilting disc mechanical valve show that it has comparable haemodynamic results to those of Medtronic-Hall mechanical valve ,and it has well-done function. The home-made C-L pugestrut valve is one of the reliable mechanical heart valves.
According to new clinical evidence, the European Society of Cardiology (ESC) and European Association for Cardio-Thoracic Surgery (EACTS) updated and published 2021 ESC/EACTS guidelines for the management of valvular heart disease. This new guideline gives recommendation for clinical assessment, internal treatment and intervention for patients with valvular heart disease with/without comorbidities, which is a globally approbatory reference for clinical practice. This article summarized the updated contents of the new guideline in terms of transcatheter therapy for valvular heart disease.
In recent years, the number of interventions for valvular heart disease has been increasing day by day, and it has become a hot topic in the field of cardiovascular surgery. Given the aging global population and trends in the prevalence of valvular disease and the broadening of indications for transcatheter aortic valve replacement (TAVR), a breakthrough of 130000 TAVR procedures is expected by 2026. In the new technology development period, the development potential and technical advantages of heart valve interventional therapy should be faced squarely. This paper focuses on key issues such as comparison of outcomes after TAVR versus surgical aortic valve replacement (SAVR), prosthetic valve endocarditis after TAVR, and broadening of indications for TAVR, as well as recommendations on how surgeons face the era of TAVR. We hope that this article will help and attract the attention of cardiac surgeons.
