Aortic root characteristics of human pulmonary autografts.
BACKGROUND After pulmonary autograft replacement of the aortic valve and root, the pulmonary artery (PA) wall is subjected to higher pressures. Concern exists that this may lead to structural and functional changes in the implanted autograft and subsequent aortic root dilatation and neoaortic regurgitation. We therefore assessed root dimensions and neoaortic regurgitation, morphological structu...
متن کاملClinical anatomy of the normal pulmonary root compared with that in isolated pulmonary valvular stenosis.
OBJECTIVES This study aimed to clarify the clinical anatomy of the pulmonary root. BACKGROUND Many descriptions of valvular anatomy have focused on the annulus, leading to varied interpretations of abnormal valves. METHODS Twenty-two heart specimens with isolated pulmonary valvular stenosis were examined to analyze the gross structure of the pulmonary root. For comparison, we examined a nor...
متن کاملEffect of Pulmonary Rehabilitation Program on Severity of Symptoms in Patients with Chronic Obstructive Pulmonary Disease
800x600 Background and Objectives: Cough and dyspnea are two most common symptoms in chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effect of pulmonary rehabilitation program on severity of symptoms in patients with chronic obstructive pulmonary disease. Materials and Methods: This study was a clinical trial in which 70 patien...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
متن کاملMeasurements of mouse pulmonary artery biomechanics.
BACKGROUND Robust techniques for characterizing the biomechanical properties of mouse pulmonary arteries will permit exciting gene-level hypotheses regarding pulmonary vascular disease to be tested in genetically engineered animals. In this paper, we present the first measurements of the biomechanical properties of mouse pulmonary arteries. METHOD OF APPROACH In an isolated vessel perfusion s...
