Abstract
BACKGROUND The use of echocardiography in pulmonary hypertension (PH) in advanced chronic obstructive pulmonary disease (COPD) is understudied. We aimed to compare the performance of echocardiography with right heart catheterization (RHC) in the diagnosis of PH in COPD patients undergoing lung transplant evaluation. METHODS We included 111 patients with severe COPD who underwent RHC in a single center as part of lung transplantation evaluation. COPD-PH and severe COPD-PH were defined based on RHC per the 6th world symposium on pulmonary hypertension. Echocardiographic probability of PH was described according to the European Society of Cardiology guidelines. Summary and univariate analyses were performed. RESULTS The mean age (±SD) was 62 (8) and 47% (n=52) were men. A total of 82 patients (74 %) had COPD-PH. The sensitivity, specificity, positive predictive, and negative predictive values of echocardiography in diagnosing COPD-PH were 43 %, 83 %, 88 %, and 34 % respectively and for severe COPD-PH were 67 %, 75 %, 50 %, and 86 % respectively. Echocardiography was consistent with RHC in ruling in/out PH in 53% (n=59) of patients. After controlling for age, sex. BMI, pack year, echocardiography-RHC time difference, GOLD class, FVC, and CT finding of emphysema, higher TLC decreased consistency (parameter estimate=-0.031; odds ratio: 0.97, 95%CI 0.94-0.99; p=0.037) and higher DLCO increased consistency (parameter estimate=0.070; odds ratio: 1.07, 95%CI 0.94-0.99; p=0.026). CONCLUSIONS Echocardiography has high specificity but low sensitivity for the diagnosis of PH in advanced COPD. Its performance improves when ruling out severe COPD-PH. This performance correlates inversely with lung hyperinflation.

Abstract
Critical mitral valve stenosis due to a failed bioprosthetic valve is associated with significant morbidity and mortality, with the transcatheter Valve-in-Valve (ViV) approach becoming a popular treatment option. We present a case of cardiogenic shock secondary to a stenotic mitral bio-prosthetic valve. The Heart team was consulted; the patient was a high-risk surgical candidate for valve replacement. He required venoarterial extracorporeal membrane oxygenation as a bridge to definitive therapy. The patient underwent a successful urgent transcatheter mitral ViV procedure with a trans-septal approach. Follow-up echocardiography showed significant improvement in mitral valve dynamics. Recently emerging transcatheter approaches for mitral ViV implantation after balloon valvuloplasty into a failed mitral valve prosthesis are technically feasible in high-risk patient populations and should be considered over re-operative mitral valve surgery.

Abstract
BACKGROUND AND AIM Cardiac sarcoidosis (CS) is the second most common cause of death in patients with sarcoidosis and data pertaining to its diagnosis and management is limited. We sought to describe diagnostic modalities and management of patients with CS in the United States, based on a national registry questionnaire. METHODS We conducted a retrospective study based on a national registry investigating 3,835 respondents to the Foundation for Sarcoidosis Research Questionnaire. The registry includes patient surveys completed between June 2014 and August 2019. Summary and univariate analyses were performed. RESULTS A total of 394 patients (10.3%) with CS were identified; 57% (n=223) were women and 81% (n=317) were white. The mean (±SD) age at diagnosis was 45 years (±13). CS was the initial presentation of sarcoidosis in 30%. Multiorgan involvement (≥3 organs) was present in 68%. Two-thirds of patients were admitted at least once to the hospital. Cardiac magnetic resonance imaging (74.4%) was the most common diagnostic modality used followed by positron emission tomography (PET) scan (59.3%) and cardiac biopsy (n=52, 13%). Most patients received corticosteroids (86%) and steroid-sparing medications (61%) including methotrexate (26%) and tumor necrosis factor (TNF) inhibitors (19%). A combined cardioverter defibrillator and pacemaker (39%) was the most common cardiac device implanted. CONCLUSIONS The prevalence of CS in this cohort was higher than previously described. CS was a common initial presentation of sarcoidosis. The diagnosis was most likely made using cMRI. Steroids, methotrexate and infliximab are the most common medications used. Conduction abnormalities and arrhythmias often occurred.

Abstract
It is common for patients with inferior myocardial infarction to experience right ventricular infarction, occurring in half of the patients with inferior myocardial infarction. Right ventricular failure due to acute right myocardial infarction is often associated with a worse prognosis. In this case, we report a patient with acute chest pain due to acute right coronary artery occlusion status post placement of multiple stents in the right coronary artery. Unfortunately, he developed refractory cardiogenic shock requiring biventricular assist device placement.

Abstract
Prosthetic valve endocarditis is a devastating infection with a challenging diagnosis and management. Despite advances in its diagnostic modalities, medical, and surgical interventions, prosthetic valve endocarditis still carries high morbidity and mortality rates. Here, we report a case of prosthetic aortic valve endocarditis that progressed to involve the paravalvular space and the importance of multimodality cardiac imaging in the early detection of paravalvular complications.

Abstract
Granular cell tumors (GCTs) are generally thought to be of Schwann cell origin and are typically S-100 positive. Up to 11% of these tumors affect the gastrointestinal tract, most commonly the esophagus, colon, and stomach. While GCTs are mostly benign, malignant and metastatic GCTs have been reported. GCTs are usually found incidentally during esophagogastroduodenoscopy, colonoscopy, imaging studies or during the evaluation of non-specific symptoms. Endoscopically, they are typically yellow in appearance with intact mucosa. On endoscopic ultrasound, they usually are hypoechoic, homogenous, smooth-edged lesions that appear to originate from the submucosal layer, although other endoscopic and ultrasound appearances have been described. There is no consensus on how to treat GCT. Surgical and conservative approaches have been described in the literature. GCTs can also affect the biliary tract, where patients may be misdiagnosed with cholangiocarcinoma. We explore the epidemiology, histology, clinical presentation, diagnosis and treatment of these tumors in the gastrointestinal tract, including the pharynx, esophagus, stomach, small intestine, large intestine and the perianal region. In addition, GCTs in the biliary tract are reviewed.

Abstract
In this study we aimed to explore the effects of epidural analgesia achieved by a combination of low-dose bupivacaine and fentanyl infused through an epidural catheter on mother, foetus and labour process in nulliparous at-term pregnant women during vaginal delivery. This study was designed in a prospective, randomised controlled manner. Epidural analgesia was achieved in 50 nulliparous women. Fifty nulliparous women did not undergo epidural analgesia procedure. The duration of the first stage of labour was significantly shortened, while the second stage was significantly lengthened in pregnant women who underwent epidural analgesia (p < 0.05). In conclusion, starting epidural analgesia application during the active phase of the first stage of labour may shorten the duration of the first stage compared with the group of nulliparous women not undergoing epidural analgesia. The factor that has an impact on this may be the addition of fentanyl to bupivacaine used for epidural analgesia.
