BACKGROUNDTricuspid regurgitation (TR) is frequently associated with severe mitral stenosis (MS), the importance of significant TR was often neglected. However, TR influences the outcome of patients. The aim of this study was to investigate the efficacy and safety of percutaneous balloon mitral valvuloplasty (PBMV) procedure in rheumatic heart disease patients with mitral valve (MV) stenosis and tricuspid valve regurgitation.
METHODSTwo hundred and twenty patients were enrolled in this study due to rheumatic heart disease with MS combined with TR. Mitral balloon catheter made in China was used to expand MV. The following parameters were measured before and after PBMV: MV area (MVA), TR area (TRA), atrial pressure and diameter, and pulmonary artery pressure (PAP). The patients were followed for 6 months to 9 years.
RESULTSAfter PBMV, the MVAs increased significantly (1.7 ± 0.3 cm 2 vs. 0.9 ± 0.3 cm 2 , P < 0.01); TRA significantly decreased (6.3 ± 1.7 cm 2 vs. 14.2 ± 6.5 cm 2 , P < 0.01), right atrial area (RAA) decreased significantly (21.5 ± 4.5 cm 2 vs. 25.4 ± 4.3 cm 2 , P < 0.05), TRA/RAA (%) decreased significantly (29.3 ± 3.2% vs. 44.2 ± 3.6%, P < 0.01). TR velocity (TRV) and TR continue time (TRT) as well as TRV × TRT decreased significantly (183.4 ± 9.4 cm/s vs. 254.5 ± 10.7 cm/s, P < 0.01; 185.7 ± 13.6 ms vs. 238.6 ± 11.3 ms, P < 0.01; 34.2 ± 5.6 cm vs. 60.7 ± 8.5 cm, P < 0.01, respectively). The postoperative left atrial diameter (LAD) significantly reduced (41.3 ± 6.2 mm vs. 49.8 ± 6.8 mm, P < 0.01) and the postoperative right atrial diameter (RAD) significantly reduced (28.7 ± 5.6 mm vs. 46.5 ± 6.3 mm, P < 0.01); the postoperative left atrium pressure significantly reduced (15.6 ± 6.1 mmHg vs. 26.5 ± 6.6 mmHg, P < 0.01), the postoperative right atrial pressure decreased significantly (13.2 ± 2.4 mmHg vs. 18.5 ± 4.3 mmHg, P < 0.01). The pulmonary arterial pressure decreased significantly after PBMV (48.2 ± 10.3 mmHg vs. 60.6 ± 15.5 mmHg, P < 0.01). The symptom of chest tightness and short of breath obviously alleviated. All cases followed-up for 6 months to 9 years (average 75 ± 32 months), 2 patients with severe regurgitation died (1 case of massive cerebral infarction, and 1 case of heart failure after 6 years and 8 years, respectively), 2 cases lost access. At the end of follow-up, MVA has been reduced compared with the postoperative (1.4 ± 0.4 cm 2 vs. 1.7 ± 0.3 cm 2 , P < 0.05); LAD slightly increased compared with the postoperative (45.2 ± 5.7 mm vs. 41.4 ± 6.3 mm, P < 0.05), RAD slightly also increased compared with the postoperative (36.1 ± 6.3 mm vs. 28.6 ± 5.5 mm, P < 0.05), but did not recover to the preoperative level. TRA slightly increased compared with the postoperative, but the difference was not statistically significant (P > 0.05). The PAP and left ventricular ejection fraction appeared no statistical difference compared with the postoperative (P > 0.05), the remaining patients without serious complications.
CONCLUSIONSPBMV is a safe and effective procedure for MS combined with TR in patients of rheumatic heart disease. It can alleviate the symptoms and reduce the size of TR. It can also improve the quality-of-life and prognosis. Its recent and mid-term efficacy is certain. While its long-term efficacy remains to be observed.

OBJECTIVETo evaluate the efficacy and experience in right ventricular pacing-percutaneous balloon aortic valvuloplasty (RVP-PBAV) for congenital aortic stenosis (AS).
METHODA total of sixteen children with AS accepted the treatment with RRVP-PBAV. The patients were at ages 6 months to 15 years, their median age was 5.4 years. Their body weight was between 8.5 and 59.0 kg, average (22.3 ± 16.5) kg. The gradient pressure across the aortic valve was measured for all the patients and aortic regurgitation was observed. The follow-up time ranged from 1 month to 5.5 years.
RESULTAll patients underwent RVP-PBAV successfully. The ratios of balloon/valve were 0.86 to 1.12. The gradient pressure varied from preoperative Δp = (96 ± 32) mmHg (1 mmHg = 0.133 kPa) to the immediate postoperative ΔP = (41 ± 26) mmHg, (P < 0.05). One case had postoperative restenosis, and 3 cases were complicated with bicuspid aortic valve deformity.
CONCLUSIONThe treatment with RVP-PBAV for congenital aortic stenosis is safe and reliable. Rapid ventricular pacing is a safe procedure to stabilize the balloon during balloon aortic valvuloplasty and may decrease the incidence of aortic insufficiency.

Transcatheter aortic valve implantation and transcatheter mitral valve repair (MitraClip) procedures have been performed worldwide. In this paper, we review the use of two-dimensional and three-dimensional transesophageal echo for guiding transcatheter aortic valve replacement and mitral valve repair.

Balloon pulnounary valvuloplasty is an established method in the treatment of congenital valvular pulmonary stenosis. Balloon valvuloplasty was performed by using one or two balloons in a total of 19 mongrel dogs. Cross sectional area ratio ranging 145-406% was used to compare the relative sizes of the pulmonary annulus the balloon Hemodynamic changes and cardiac damages in single and double balloon groups were analyzed. Survival time of double balloon group was longer than that of single balloon group(P<0.05). Increment of the right ven?dular systolic pressure in single balloon group (mean 38 mmHg) was greater than that in double balloon group (mean 18 mmHg) (p<0.05). Decrement of the femoral arterial pressure in single balloon group (mean 87 mmHg) was greater than in double balloon group (mean 41 mmHg) (p<0.05). The locations of trauma were mainly the right ventricular free wall, the main pulmonary artery, the anterior leaflet of the pulmonary valve and in a less degree, anterior wall of the right atrium, the right ventricular outflow tract and the left pulmonary artery in the order of frequency. There were no significant differences in cardiac damages between single and double balloon groups (P>0.05). Major microscopic findings were sloughing of the endotheliu, fibrin deposition, hemorrhage, localized myocardial infarction and so on. In conclusion, double balloon pulmonary valvuloplasty is superior to single balloon technique in survival time and hemodynamics. Therefore, double, balloon technique is recommended for the pulmonary valvuloplasty.
