Transesophageal echocardiography combining with peripheral injection of agitated saline solution is a useful diagnostic tool to detect the intrapulmonary shunt. We performed transesophageal contrast echocardiography in a case of hepatopulmonary syndrome with normal pulmonary angiography to define the intrapulmonary right-to-left shunt bilaterally.
Right pneumothorax complicated by an endocardial atrial lead has never been reported. Herein, we report on a small-build 79-year-old Taiwanese woman who suffered from complete AV block and underwent dual-chamber permanent pacemaker implantation. An active fixation screw-in atrial lead was chosen. The procedure was complicated by right pneumothorax… (More)
Coronary arterio-venous fistula (CAVF) is a rare coronary artery anomaly. We demonstrated the rare findings of a large congenital aorto-right atrial fistula with initial presentation of heart failure symptoms. Transthoracic echocardiography and transesophageal echocardiography made the accurate diagnosis. Further haemodynamic and angiographic study proved… (More)
Adolescent idiopathic scoliosis (AIS) is a common orthopedic disorder of unknown etiology and pathogenesis. Melatonin and melatonin pathway dysfunction has been widely suspected to play an important role in the pathogenesis. Many different types of animal models have been developed to induce experimental scoliosis mimicking the pathoanatomical features of… (More)
This study describes a case of exercise-induced myocardial ischaemia accompanied by complete atrioventricular block (CAVB). A 59-year-old man with major depression, treated with regular imipramine and lithium for 20 years, experienced syncope episodes during exercise. Exercise, testing initially, identified ST depression in the inferior leads, and later… (More)
