Purpose: In this study, subjects with femoral anterior glide type were examined to investigate the effects of femoral head anterior glide fixation during active straight leg raise on the strength of the hip flexor in a supine position. Methods: Fifteen subjects participated in this study. All subjects were classified through an evaluation form for femoral anterior glide type (FAGT). The strength of the hip flexor was measured during active straight leg raise test (ASLR test), and compared with and without femoral anterior glide fixation in a supine position. The fixation of the femoral head was achieved as per the therapist’s manual guidelines. Paired t-test was applied to compare changes in the strength of the hip flexor according to fixation conditions. The level of statistical significance was set at α= 0.05. Results: The strength of the hip flexor was lesser during the ASLR test with fixation compared to without fixation (p= 0.007). Conclusion The strength of the hip flexor decreases with fixation. Results of this study revealed a difference between hip flexor strength, with and without femoral anterior glide fixation during ASLR, in subjects with femoral anterior glide type.

Sustemic arterialization of the lung without sequestration is the rarest from of congenital anomalous systemic arterial supply to the lung, where an anomalous systemic artery arising from aorta supplies a normal unsequestrated segment of the lung. The non-sequestrated lung parenchyma which is supplied by an aberrant artery, has no parenchyma or bronchial abnormalities, and there is a normal connection with the bronchial trees. The symptoms of this disease varies. In most patients, it is often asymptomatic, but symptoms including dyspnea, hemoptysis, and central nervous system complications are possible. Here, we report a case of systemic arterialization of the lung without sequestration, which confirmed by angiography, with a review of the literature.

OBJECTIVES:We performed a prospective observation for the patients with chronic nonvalvular atrial fibrillation who underwent electrical cardioversion after failed pharmacological cardioversion with amiodarone. The aim of this study was to look at the immediate sinus conversion rate, the maintenance rate of sinus rhythm at long-term follow-up, and the clinical and echocardiographic parameters that influence on the rate of immediate sinus conversion and maintenance of sinus rhythm. At simultaneously, we intended to evaluate the efficacy of electrical cardioversion for the patients with chronic nonvalvular atrial fibrillation. METHODS: After anticoagulation therapy with coumadine for four weeks before cardioversion, we tried pharmacological cardioversion with amiodarone first. Failed cases included in this study. The direct current cardioversion was performed under transesophageal echocardiography monitoring to exclude the left atrial thrombus and to measure various echocardiographic parameters. After successful sinus cardioversion, we prescribed amiodarone with maintenance doses and coumadine at least 4 weeks. Transthoracic echocardiography was performed before cardioversion and one day, one month, 3 months, 6 months, and 9 months after sinus conversion. The minimum duration of atrial fibrillation was one month before the trial of pharmacological cardioversion. RESULTS: 1) The total number of patients was forty three (male: 28, female: 15, average age: 60+/-9). The initial success rate of sinus conversion was 88 %. 2) The maintenance rate of sinus rhythm with maintenance dose of amiodarone was 52 % after 9 months follow-up. 3) The direct current cardioversion was performed to 10 patients among 17 patients who recurred atrial fibrillation after sinus conversion. Among 10 patients, 5 patients of them were converted to sinus rhythm and maintained sinus rhythm after 9 months follow-up. 4) The initial success rate of sinus conversion was significantly higher in patients with lone atrial fibrillation compared with those patients with other associated heart disease (100 % vs. 83 %, p < 0.05), but the long-term maintenance rate of sinus rhythm was not influenced by the presence of associated disease. 5) The duration of atrial fibrillation before cardioversion was shorter in patients who were naintained sinus rhythm than that of those who were recurred atrial fibrillation. 6) The initial energy requirement at sinus conversion was lower in the patients who were maintained sinus rhythm than that of those who were recurred atrial fibrillation at 9 months follow-up. CONCLUSIONS: Direct current cardioversion was an effective treatment modality for patients with chronic nonvalvular atrial fibrillation after failure of pharmacological cardioversion with amiodarone.

BACKGROUND: Significant aortic stenosis of various underlying etiologies presents with similar clinical characteristics and is usually treated with aortic valve replacement. We performed a clinical study to evaluate the clinical characteristics, changes of echocardiographic parameters before and after aortic valve replacement in adult aortic stenosis patients. METHODS: From January 1991 through December 1995, 159 patients underwent aortic valve replacement at Sejong General Hospital. Sixty-two cases(39%) of those patients were pure or predominant aortic stenosis. We observed the clinical characteristics, etiology, operative procedure, perioperative complication and mortality, And we observed the changes of echocardiographic parameters such as mean and peak pressure gradients at aortic valve, ejection fraction, systolic and diastolic left ventricular internal dimensions, left ventricular wall thickness, left ventricular mass index retospectively at preoperative and postoperative periods regularly within 1 month, 1 yr, 3 yrs after operation(mean follow up period : 16 months, 1-36 months). RESULTS: 1) The age of patients ranged from 31 to 71 years(mean 55+/-11), and 60%(37 cases) of them were men. 2) Regarding underlying heart disease, the most common etiology of aortic stenosis was rheumatic valvular heart disease(32 cases, 52%), followed by congenital bicuspid aortic valve(16 cases, 25%) and degenerative change(14 cases,23%). 3) 44 cases(77%) of the patients had dyspnea,12 cases(19%) had chest pain, and 5 cases(8%) had history of syncope at the time of operation. Asymptomatic patient was only 1 case. 4) Seven patients(11%) had associated coronary artery disease, and only 1 case(about 2%) underwent concomitant coronary bypass surgery. 5) Post-operative complications which developed within 1 month were bleedings(8 cases, 13%), arrhythmias(7 cases, 11%) and infections(4 cases, 6%). After 1 month, bleedings related with anticoagulation were most common(7 cases, 11%). Other complications were hemolytic anemia(1 case), and aortic dissection(1 case). There was one surgery related mortality(2%) which happened during operatin due to myocardial ischemia. 6) The size of implanted prosthetic valves ranged from 19 to 25mm(mean 22+/-2mm). Larger valves(23-25mm) showed lower peak(p=0.839) and mean pressure gradients(p=0.019) than smaller valves(19-21mm). 7) We observed that peak and mean pressure gradient, left ventricular internal dimension, and left ventricular mass index had decreased significantly after aortic valve replacement. 8) The average preoperative functional class(2.3) had improved significantly at 1 month after surgery(1.2), and 1 year after surgery(1.0). CONCLUSIONS: In our series, the most common etiology of aortic stenosis was rheumatic valvular disease(52%). The incidence of combined coronary artery disease was 11%, lower than other reports. And only 1 case(2%) underwent concomitant coronary artey bypass graft surgery. The average size of implanted valves was 22mm, and the larger size had lower transaortic peak and mean pressure gradients after operation. The most common perioperative complication was bleeding and mortality rate was about 2%. Echocardiography was useful for evaluation of postoperative changes, such as transaortic peak and mean pressure gradient, left ventricular internal dimension and left ventricular mass index.

OBJECTIVE: Systemic embolism related with left atrial thrombi is a well known complication of percutaneous ballon valveloplasty of the mitral valve stenosis. The presence of left atrial thtombi is believed to be a contraindication to balloon valvuloplasty. The purpose of this study was to determine whether balloon valvuloplasty is possible in mitral stenosis patients with left atrial thrombi after oral anticoagulation therapy. METHODS: We studied 13 consecutive patients(12 : female, 1 : male, mean age : 44+/-11) who had mitral stenosis and left atrial appendage thrombi by serial transesophageal echocardiography before balloon valvuloplasty of the stenotic mitral valve from May 1995 to January 1997. We started oral anticoagulation in those 13 patients with mitral stenosis and left atrial appendage thrombi to keep the INR 2-3. Regular follow up was performed by transesophageal echocardiagraphy to determine whether the left atrial appendage thrombi are resolved. Patients underwent percutaneous balloon valvuloplasty after complete resolution of left atrial appendage thrombi. RESULTS: 9 patients(69.2%) underwent balloon valvuloplasty after complete resolution of left atrial appendage thrombi with oral anticoagulation for average 6 months. Two (15.4%) patients had normal sinus rhythm. Three patients had coronary A-V fistular due to neovascularization to left atrial appendage thrombi. In four patients, oral antiocoagulation failed to resolve the left atrial appendage thrombi and they underwent balloon valvuloplasty under TEE guide with special caution to avoid systemic embolization. There were no complications such as systemic embolization in those 4 patients. CONCLUSION: Left atrial appendage thrombi in mitral stenosis could be resolved in high proportion(69.2%) by oral anticoagulation therapy. Percutaneous mitral balloon valvuloplasty could be a safe and effective treatment modality despite of the presence of left atrial appendage thrombi after adequate oral anticoagulation therapy.

A 43-year-old female patient with a congenital right coronary artery to right atrial fistula presented as congestive heart failure and aortic valve infective endocarditis. The diagnosis was made on the basis of echocardiography, especially TEE and confirmed by tight heart catheterization & aortography. She underwent aortic valve replacement due to severe aortic valve regurgitation with vegetations, fistulectomy and coronary aneurysmorrhaphy. The postoperative course was uneventful. She was treated with antibiotics because of infective endocarditis for 6 weeks. At present she remains well and visits out patient clinic regularly for oral anticoagulation without problem.
