The role of penile elastography in the evaluation of erectile dysfunction in patients with chronic obstructive pulmonary disease.

Introduction: In this study, we aimed to measure the change in penile stiffness by evaluating corpus cavernosum (CC) with shear wave elastography (SWE) in patients with chronic obstructive pulmonary disease (COPD).

Material And Methods: Seventy outpatient patients aged 50-80 years who were diagnosed with COPD were evaluated using SWE. Patients were divided into 2 groups according to the International Index of Erectile Function-5 (IIEF-5) questionnaire (IIEF-5 >17: Group A, IIEF-5 <17: Group B).

Early diagnosis of right ventricular systolic dysfunction by tissue Doppler-derived isovolumic myocardial acceleration in patients with chronic obstructive pulmonary disease.

Objectives: The aim of the study was to assess validity of tissue Doppler imaging (TDI)-derived right ventricular (RV) myocardial systolic velocities in early detection of RV systolic dysfunction in chronic obstructive pulmonary disease (COPD).

Methods: Ninety COPD patients (50 pure COPD and 40 with right heart failure [RHF]) and 40 controls were enrolled. Respiratory function tests, conventional echocardiographic parameters, and TDI-derived isovolumic myocardial acceleration (IVA), peak myocardial velocity during isovolumic contraction (IVV), peak velocity during systolic ejection (Sa) were measured.

Right atrial compression due to idiopathic right diaphragm paralysis detected incidentally by transthoracic echocardiography.

Unilateral diaphragm paralysis (UDP) is an important and often unrecognized cause of dyspnea. We report a 72-year-old man in whom UDP was incidentally detected by transthoracic echocardiography. He was asymptomatic at rest, but experienced dyspnea on exertion.
