ABSTRACT
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). The measurements were made in both transverse and longitudinal sections. Results: The mean age of the patients was 60 ±7.9 years. The duration of COPD was significantly higher in Group B than in Group A (p = 0.003). The mean SWE values of right transverse mid-portion of corpus penis (RTM) and left transverse mid-portion of corpus penis (LTM) in Group B (21.1 ±5.6 kPa and 20.8 ±4.8 kPa, respectively) were significantly higher than in Group A (15.2 ±2.3 kPa and 15.8 ±2.7 kPa, respectively); (p <0.001 and p <0.001, respectively). There was a significant negative correlation between IIEF-5 scores and the duration of COPD (p <0.05). There was a significant negative correlation between IIEF values and RTM and LTM values of the patients (p <0.05 and p <0.05, respectively). There was a significant positive correlation between the duration of COPD and both RTM and LTM values (p <0.05 and p <0.05, respectively). Conclusions: In our study, according to the SWE findings, we showed the effect of systemic changes created by COPD on penile tissue and the negative effect of this on erectile function in patients.
ABSTRACT
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. RESULTS: All the TDI-derived RV systolic velocities were impaired in COPD (P = 0.0001) compared to controls. IVA was the only parameter that could distinguish the patients with pure COPD and COPD with RHF (P = 0.0001). IVA was found to be significantly correlated with FEV1 (r = 0.41, P = 0.0001), FEV1/FVC (r = 0.43, P = 0.0001), pulmonary artery pressure (r =-0.34, P = 0.001), pulmonary flow acceleration time (r = 0.48, P = 0.0001), and tricuspid annular systolic excursion (r =-0.41, P = 0.0001). In addition, IVA < or = 2.7 m/sec(2) was able to predict COPD patients from controls with 81% sensitivity, 98% specificity and IVA < or = 1.9 m/sec(2) predicted COPD patients accompanied by RHF with 82% sensitivity, 77% specificity from patients without RHF. CONCLUSIONS: TDI-derived RV IVA is a novel, noninvasive echocardiographic index which may be used in the assessment of subclinical RV dysfunction in patients with COPD.

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. Chest radiography was not pathognomonic in this case because the heart silhouette obscured the left diaphragmatic contour. Transthoracic echocardiography showed an extrinsic compression to the right atrium. Right atrial collapse was obvious during heart movements with variation upon respiratory movements. There was no pericardial effusion nor any solid mass lesion. Fluoroscopic sniff test demonstrated a significant paradoxical elevation of the paralyzed right diaphragm in inspiration. Thoracic and abdominal computed tomography scans did not show any other pathology. The diagnosis was made as idiopathic UDP.
