Background and Purpose: The prevalence of a patent foramen ovale has been shown to be increased in patients with ischemic stroke. Transesophageal echocardiography, transthoracic echocardiography, and transcranial Doppler examination with contrast injection can all be used to search for a patent foramen ovale. We compared the accuracy of these techniques for identifying a patent foramen ovale in...
A subaortic membrane is an uncommon cause for left ventricular outflow tract obstruction. Hypertrophic cardiomyopathy with dynamic left ventricular outflow tract obstruction would mask the presence of the subaortic membrane on transthoracic echocardiography and cause a false diagnosis. We report a patient with subaortic stenosis due to flail subaortic membrane misdiagnosed as obstructive hypert...
The modern generation of transthoracic defibrillators now employ impedance compensated biphasic waveforms. These new devices are superior to those with monophasic waveforms and practice is currently switching to biphasic defibrillators for the treatment of both ventricular and atrial fibrillation. However, there is no universal guideline for the use of biphasic defibrillators in direct current ...
Myocardial bridging is a common congenital coronary abnormality recognized primarily with systolic narrowing or 'milking effect' shown by coronary angiography. We report the case of a 58-year-old man with signs and symptoms of myocardial ischemia who underwent transthoracic echocardiography and coronary angiography. The present case suggests the clinical role of transthoracic echocardiography i...
Background Echocardiography is the preferred initial imaging method for assessment of cardiac masses. However, CMR, with its excellent tissue characterization and wide field of view, can provide unique information in the evaluation of cardiac masses. Our objective was to identify CMR and echocardiographic parameters that predict the presence of tumor or malignancy in biopsy proven cardiac masse...
BACKGROUND For esophageal cancer patients, radical esophagolymphadenectomy is the cornerstone of multimodality treatment with curative intent. Transthoracic esophagectomy is the preferred surgical approach worldwide allowing for en-bloc resection of the tumor with the surrounding lymph nodes. However, the percentage of cardiopulmonary complications associated with the transthoracic approach is ...
To compare the clinical outcomes and prognoses in patients with gastroesophageal junction adenocarcinoma (Siewert type II/III), by transthoracic and transabdominal hiatal approaches. Siewert II/III gastroesophageal junction adenocarcinomas patients (334 cases) underwent different surgical procedures at the Affiliated Hospital of Qingdao University from July 2007 to July 2012 and were analyzed r...
OBJECTIVE To examine factors determining defibrillation success and outcome in patients with ventricular fibrillation. DESIGN Observational prospective study of age, sex, transthoracic impedance, site of cardiac arrest, ventricular fibrillation duration and amplitude, primary or secondary ventricular fibrillation, aetiology, number of shocks to correct ventricular fibrillation, and drug treat...
