Abstract: Tricuspid insufficiency founded in the setting of left-sided heart disease is usually secondary tricuspid insufficiency caused by tricuspid valve annular dilation. Some patients had rheumatic tricuspid valve diseases. Tricuspid valve repair rather than valve replacement is recommend for functional tricuspid regurgitation. Linear annuloplasty and ring annuloplasty are two main tricuspid valve repair methods. However, the indications for treatment of secondary tricuspid regurgitation remain controversial. The optimal surgical repair technique to eliminate secondary tricuspid regurgitation remains challenging. In this article, we review the assessment of tricuspid valve lesions, criteria for correction, and surgical management of secondary tricuspid insufficiency.methods. However, the indications for treatment of secondary tricus
Abstract: Objective To summarize the clinical results of homemade flexible annuloplasty ring in mitral valve repair, in order to discuss the appropriate ring size. Methods Sixtysix patients (55 males,and 11 females with a mean age of 44.62±15.94 years) with mitral insufficiency underwent mitral valve repair with homemade flexible annuloplasty ring from April 2002 to November 2009 in Fu Wai Hospital. In order to choose the ring with an appropriate size, we made and kept to the following principles: if the intercommissural distance was bigger than size 30, we chose a ring 2size smaller; if the measured distance was smaller than size 30, 1size smaller ring would be chosen. Patients were followed by echocardiography to observe the mitral valve function. Results All patients were cured and discharged from the hospital. The results of echocardiography showed mild to moderate regurgitation in 1 patient, mild regurgitation in 11 patients, and normal mitral function or trace regurgitation in the rest 54 patients. Mitral valve forward velocity was 1.40±0.30 m/s with no mitral stenosis or systolic anterior motion (SAM) of the anterior mitral leaflet. Fiftyone patients were followed up from 2 months to 7 years(24.60±25.90 months). The results of echocardiography on 38 patients showed that 1 patient had moderate regurgitation, 5 patients had mild to moderate regurgitation, 9 patients had mild regurgitation and others had normal mitral function or trace regurgitation. For these 38 patients included in the followup study, mitral valve forward velocity was 1.50±0.40 m/s with no mitral stenosis, SAM or left ventricular outlet tract obstruction. During the followup, the left atrium size (43.19±10.48 mm vs. 48.59±9.40 mm, t=4.524, P=0.000) and left ventricular end diastolic diameter (52.64±7.35 mm vs. 6269±8.77 mm, t=7.607, P=0.000) decreased significantly than the preoperative size and diameter respectively. The application of restrictive homemade flexible annuloplasty ring in mitral valve annuloplasty had satisfactory, durable and stable clinical results.
Objective To summarize clinical characteristics and treatment results of adult patients with coronary heart disease and ventricular aneurysm,and evaluate surgical outcomes. Methods Clinical data of 86 adult patients with coronary heart disease and ventricular aneurysm who underwent surgical treatment in Fu Wai Hospital from January 2011 to November 2012 were retrospectively analyzed. There were 70 male and 16 female patients with their average age of 57.7±10.6 years and average body weight of 71.7±10.5 kg. Preoperative echocardiography or left ventriculography showed left ventricular thrombus in 22 patients. Coronary angiography showed 47 patients with 3 vessel disease,29 patientswith 2 vessel disease,and 10 patients with single vessel disease. Sixteen patients underwent direct linear suturing of theaneurysm off pump,39 patients underwent simple linear suturing under cardiopulmonary bypass,15 patients received endoventricular purse-string reconstruction,and 16 patients received endoventricular purse-string reconstruction and patch plasty. Three patients underwent reexploration for bleeding. Sixty-four patients received concomitant coronary artery bypass grafting(CABG). Results Postoperatively 2 patients(2.3%) died of refractory ventricular fibrillation and multiple organ dysfunction syndrome respectively. Patients undergoing concomitant CABG received 2.3±1.2 grafts on the average. Seventy-eightpatients (92.9%) were followed up for 2-24 months after discharge. During follow-up,patients’ angina symptoms significantlyresolved,heart function improved in varying degrees,and no new sign of myocardial ischemia was found on electrocardiogram.Left ventricular ejection fraction (LVEF) was significantly higher than preoperative LVEF(51%±7% vs. 41%±9% ,t=6.20,P=0.00),and left ventricular end-diastolic diameter (LVEDD) was significantly smaller than preoperative LVEDD (54.2±6.2 mm vs. 56.0±6.8 mm,t=4.60,P=0.00) . Conclusion Ventricular aneurysm repair and concomitant CABG (or ventricular septal perforation repair,mitral valvuloplasty et al) are positive and effective treatment strategies for postinfarction ventricular aneurysm. Satisfactory clinical outcomes can be achieved by individualized treatment based on appropriate surgical strategies according to the size of ventricular aneurysm.
ObjectiveTo assess early and mid-term outcomes and our clinical experience of reduction ascending aortoplasty (RAA) for patients with aortic valve disease and ascending aortic dilatation, and improve treatment effects. MethodsClinical data of 36 patients with aortic valve disease and ascending aortic dilatation who underwent aortic valve replacement and RAA in Fu Wai Hospital between January 2002 and August 2010 were retrospectively analyzed. There were 26 male and 10 female patients with their age of 7-72 (51±16) years. Ascending aorta diameter (AAD) was measured by echocardiography preoperatively, postoperatively, during follow-up and compared. ResultsThere was no perioperative death. Cardiopulmonary bypass time was 96.2±28.3 minutes, and aortic cross-clamp time was 69.2±22.1 minutes. Posto-perative hospital stay was 11.0±7.8 days. All the 36 patients were followed up after discharge for 1.1-9.0 (4.0±2.3) years. During follow-up, there was 1 death, but none of the patients needed reoperation. Echocardiography showed normal aortic valve function. Postoperative AAD was significantly smaller than preoperative AAD (36.4±6.1 mm vs. 46.8±4.6 mm, t=13.12, P=0.00). AAD during follow-up was significantly larger than postoperative AAD (40.8±6.8 mm vs. 36.4±6.1 mm, t=-2.64, P=0.01) but significantly smaller than preoperative AAD (40.8±6.8 mm vs. 46.8±4.6 mm, t=3.48, P=0.00). ConclusionEarly and mid-term outcomes of RAA are satisfactory for patients with aortic valve disease and ascending aortic dilatation, but long-term results need further observation.
