Chest wall syndrome is the most frequent cause of chest pain complained by patients admitted to physician’s office, in outward as well emergency department. It may affect all ages with sex ratio 1:1 between man and woman. History illness sensibility palpation or tenderness were keys diagnostic approach. Pain was generally moderate, localized, continuous intermittent over a number hours days wee...
To examine the mechanism of mitral flow deceleration in diastole and its potential influence on the genesis of third (S3) and fourth (S4) heart sounds, we simultaneously recorded left atrial and left ventricular pressures (micromanometers), mitral flow velocity (electromagnetic catheter-tip flow velocity meter), and internal and external phonocardiograms in 25 open-chest dogs. Diastolic time in...
Between 1994 and 2012, chest wall resection and reconstruction were performed 15 patients (16 cases) with primary chest wall tumors, metastatic tumors. and chest wall recurrence of breast carcinoma. In all the patients, reconstruction of the chest wall was performed using layers of polypropylene Marlex mesh sheets. In 9 patients, only Marlex mesh sheets were used. The post-operative course was ...
BACKGROUND Aortic stiffening contributes to the left ventricular (LV) afterload, hypertrophy, and substrate for diastolic dysfunction. It is also known that aortic elastic properties could be investigated with color tissue Doppler imaging (TDI) in aortic upper wall. The purpose of this study is to evaluate the relation of aortic upper wall TDI and aortic stiffness and other parameters of LV dia...
According to the thoracic pump model of cardiopulmonary resuscitation (CPR), the heart serves as a passive conduit for blood flow from the pulmonary to the systemic vasculature, necessitating an open mitral valve and anterograde transmitral blood flow during chest compression. To assess the applicability of this model to manual CPR techniques, two-dimensional echocardiograms were recorded from ...
