BACKGROUND: To evaluate the influence of changes in mitral valve area (MVA) and left atrial pressure on pulmonary vein flow (PVF) we analyzed PVF with transesophageal echocardiography (TEE) before, after and one-year after percutaneous mitral valvuloplasty (PMV) in patients with mitral stenosis (MS) in sinus rhythm. METHODS: PMV was guided with TEE. Follow-up TEE was done about one year after PMV. MVA and transmitral mean gradient (TMG) were measured. Systolic velocity (S), diastolic velocity (D), atrial reversal velocity (AR), their time-velocity integral (S-TVI, D-TVI, AR-TVI) and their ratio (S/D ratio, S-TVI/D-TVI ratio were evaluated. RESULTS: The number of patients was twenty-two (F:20). The age was 39+/-9 years (range:26-64). Follow-up duration was 16+/-6 months (range:7-28). MVA increased from 0.9+/-0.2 cm2 to 1.9+/-0.3 cm2 after PMV and decreased to 1.7+/-0.3 cm2 on follow-up TEE significantly. TMG decreased from 15.4+/-4.3 mmHg to 5.5+/-1.9 mmHg after PMV and was 6.2+/-2.4 mmHg on follow-up. S increased significantly on follow-up at both pulmonary vein (PV). D increased on follow-up at left PV. S/D ratio increased on follow-up at both PV. AR increased on follow-up at both PV. S-TVI increased after PMV at left PV and increased on follow-up at both PV. D-TVI had no change. S-TVI/D-TVI ratio increased on follow-up at left PV. AR-TVI increased on follow-up at right PV. CONCLUSIONS: The main changes after PMV in patients with MS in sinus rhythm were increasing tendency in S, S-TVI, S/D ratio, S-TVI/D-TVI ratio and AR. And these changes were statistically significant on follow-up TEE rather than immediately after PMV.

BACKGROUND: Balloon mitral valvuloplasty is a favorable procedure as a therapy for mitral stenosis because it minimizes morbidity and shorten hospital stay compared with surgical mitral commissurotomy or mitral valve replacement. Recent reports about concomitant transesophageal echocardiography guide in addition to fluoroscopy suggest that transesophageal echocardiograpy can provide additional benefits during balloon mitral valvuloplasty especially in transseptal puncture, balloon positioning, evaluation of immediate result, and early detection of complications. We performed this study to identify the potential benefits of on-line transesophageal echocardiography guide during balloon mitral valvuloplasty. METHOD: We performed balloon mitral valvuloplasty under on-line transesophageal echocardiography guide in addition to fluoroscopy in 70 patients(male:14, female:56, mean age:44+/-13) with rheumatic mitral stenosis from May 1995 to May 1996. Thirty-two(46%) patients had atrial fibrillation. Included patients were symptomatic with more than NYHA class 2 symptom. Patients with mitral valve score more than 11 and mitral regurgitation more than 2/4 were excluded. Inoue balloons were utilized in all cases. RESULTS: The average mitral valve area increased from 0.9+/-0.2cm2 before valvuloplasty to 1.8+/-0.4cm2 after valvuloplasty(p<0.0001). The averagetransmitral pressure gradient measured by continuous wave Doppler decreased from 14+/-6mmHg before valvuloplasty to 5+/-2mmHg after valvuloplasty(p<0.0001), and the average left atrial pressure measured by catheterization decreased form 22+/-8 mmHg before valvuloplasty to 11+/-5mmHg after valvuloplasty(p<0.0001). The average procedure time was 64+/-22 minutes(ranged from 13 to 150 minutes) and the average fluoroscopy time was 19+/-15 minutes(ranged from 1 to 94 minutes). Two patients underwent surgery due to severe mitral regurgitation associated with papillary muscle rupture which developed after valvuloplasty. In one patient, transesophageal echocardiography detected pericaridal tamponade during the procedure and the transducer was quickly switched to transthoracic transducer to guide the pericardial puncture site. The pericardial tamponade was drained with pigtail catheter and the patient underwent balloon mitral valvuloplasty successfully a week later. Four patients were pregnant at the time of the valvuloplasty procedure and the valvuloplasty was successfully performed with minimal fluoroscopy time(1-3 minutes) without complications in all four patients. Five patients had thrombus in left atrial appendage, but the transesophageal echocardiography was useful in monitoring the ballon position during the procedure and the valvuloplasty was successfully performed without embolic complications in all five patients. CONCLUSION: The transesophageal echocardiography is a very useful guiding adjunct during balloon mitral valvuloplasty in transseptal puncture, balloon positioning, evaluation of immediate result, early detection of complications, and shortening fluoroscopy time especially in pregnant women.

BACKGROUND: Percutaneous mitral balloon valvuloplasty(PMV) is a good treatment modality for patient with mitral stenosis(MS). But it is considered relatively contraindicated in patients with left artrial thrombi because of high risk of embolism. Limitted studies have suggested the feasibility of PMV in patients with left atrial appendage(LAA) thrombi. This study was performed to evaluate the feasibility and safty of PMV in patients with LAA thrombi using Inoue balloon under the transesophageal echocardiographic (TEE) monitoring. METHOD: PMV was performed in 5 patients diagnosed as MS with LAA thrombi from October, 1995 to July, 1996. Four cases were female, and one case was male. Their mean age was 525(46-58years old). Two of them had history of cerebrovascular accident(CVA). The duration of anticoagulant treatment was 6-49 moths. All patients underwent PMV using Inoue balloon catheter under the TEE monitoring. RESULTS: EKG finding of all 5 patients were atrial fibrillation(Af). Their mitral valve score were 5-10(Mean score was 82). Transmitral mean pressure gradient was decreased from 14.62.1 to 5.82.0mmHg, and mitral valve increased from 0.840.43 to 1.720.19 after PMV. There was no procedure related complication. In 3 cases of them LAA thrombi diappeared in the follow up TEE. In two patients, the LAA thrombi were calcified and remained unresolved at the time of follow up TEE( 6month-and 12 month-F/U, eath). CONCLUSION: Although the reported number of PMV in patients with LAA thrombi is small in this study, we believe that, with special precaution and TEE monitoring, LAA thrombi is no longer an absolute contraindication to PMV.

Limb salvage operations for osteosarcoma of the extremity usually consist of wide excision and skeletal reconstruction. Most osteosarcoma patients are anemic prior to the surgery as majority of them undergo preoperative neo-adjuvant chemotherapy; thus, it is necessary to treat anemia before and after the surgery since limb salvage operation tends to accompany significant blood loss. Despite the fact that blood transfusion has bad influence on prognosis, complication, and postoperative outcome of cancer patients, it is still considered as a standard management to fix anemia for limb salvage operations. We would like to present a case report in which the authors succeeded in performing limb salvage operations on patients with distal femur osteosarcoma without transfusion.
