Exercise 201Tl myocardial scintigraphy has provided a noninvasive means of identifying myocardial perfusion abnormalities in patients with HCM. On the other hand, apical hypertrophic cardiomyopathy (APH) is reported as a subtype of HCM. Whether APH is essentially equal to HCM or not is controversial. To assess myocardial ischemia in patients with APH, we studied 28 patients with APH, with exercise 201Tl SPECT. Myocardial perfusion images were obtained immediately after submaximal exercise and again after a 3-hour delay. Regional perfusion defects during exercise were identified in 19 of the 28 patients (68%) with APH. Complete reversible defects were observed in 15 (79%) patients with APH. Although perfusion defects were present in all regions of the left ventricle in patients with HCM, they were present only in the apical region in patients with APH. Thus, reversible 201Tl perfusion abnormalities commonly occur during exercise in patients with APH as well as in patients with HCM.","PeriodicalId":76077,"journal":{"name":"Kokyu to junkan.

Subjects were 23 patients with Duchenne's muscular dystrophy (DMD) and were divided into two groups by the presence of ventricular tachycardia (VT). Age-matched healthy volunteers were obtained as controls. Abnormal SA-ECG was identified from the data in the controls as over 97 percentile of H/L ratio. Frequency domain analysis from last 40 ms of QRS wave to 80 ms of ST segment was most capable to distinguish the DMD patients with VT from the patients without VT, compared to analysis from last 20 ms. Whereas, analysis from QRS onset failed to detect VT patients. Although filter processing reduce the power of low frequency and increase the H/L ratio, sensitivity for predicting VT was not enhanced significantly. In conclusion, the frequency-domain analysis during the terminal 40 ms of the QRS complex and 80 ms of ST segment was most optimal condition to distinguish the DMD patients with VT.","PeriodicalId":76077,"journal":{"name":"Kokyu to junkan.

Microwave energy generated by a device with a frequency of 2450 MHz, was delivered via a bipolar electrode coaxial catheter with an electrode ball tip. Microwave ablation was applied (50 watts for 15-150 sec.) on the left ventricular endocardium in 6 dogs. No ventricular arrhythmia occurred during ablation in any of the dogs when microwave catheter ablation was applied for less than 45 sec. However, when the duration of microwave catheter ablation was longer than 45-60 sec, ventricular premature contractions were observed in all 6 dogs. When ablation time was set for a longer time, the dogs developed nonsustained ventricular tachycardias. Nevertheless, ventricular arrhythmias after ablation did not occur in all dogs. Ventricular programmed stimulation after ablation did not induce ventricular tachycardia in any of the dogs. When ablation time lasted more than 120 sec, the coagulation layer was extended to the epicardium in all 6 dogs. The results of this study suggest that microwave ablation is feasible for the treatment of tachyarrhythmias from a deep focus of the ventricular myocardium.","PeriodicalId":76077,"journal":{"name":"Kokyu to junkan.

On admission to the hospital, her lung scintigram showed multiple segmental perfusion defects in the right lung. Pulmonary angiography showed several thrombi in the proximal pulmonary artery. A diagnosis of pulmonary thromboembolism was made. AT-III activity was found to be only 50% of normal value, indicating that the pulmonary thromboemboli were due to AT-III deficiency. The patient was then put on anticoagulants for two years. When she was 43-year-old, she was admitted to Keio University Hospital because of worsening of dyspnea. After admission her dyspnea had got better due to bed rest. Her brain CT, which was performed because of her gait disturbance, indicated past right cerebellar infarction. We gave her 2 mg of warfarin and maintained a thrombotest of about 30%. The investigation of her family revealed that her son also showed decrease AT-III activity, indicating a congenital abnormality. 26 families with this disease have been reported in Japan. Most had venous thromboemboli, but only a few cases had brain infarction as well. In addition, it is suggested that an estrogen therapy for irregular menstruation may have contributed, in this particular case, to the onset of thromboemboli.","PeriodicalId":76077,"journal":{"name":"Kokyu to junkan.
