Correlation of Echocardiographic and Right Heart Catheterization Estimations of Pulmonary Artery Systolic Pressure.

Background: Pulmonary artery pressure (PAP) is one of the most important and valuable markers in cardiovascular disease, measured by right heart catheterization (RHC) as the gold standard diagnostic modality. However, due to several limitations, such as invasiveness, lack of repeatability, and high health costs, echocardiographic estimation of PAP has been used to substitute RHC for diagnosis and monitoring of this disease. This study aimed to evaluate the correlation of echocardiographic and RHC estimations of systolic PAP.

Cystic echinococcosis (CE) or hydatid disease is a zoonosis caused by ingestion of the eggs of the tapeworm . Larger cysts can cause symptoms by compressing surrounding tissues. Large cysts can also rupture and cause sudden onset of cough, fever, hypersensitivity reactions, and massive hemoptysis.

Intermediate-Dose versus Standard-Dose Prophylactic Anticoagulation in Patients with COVID-19 Admitted to the Intensive Care Unit: 90-Day Results from the INSPIRATION Randomized Trial.

Background: Thrombotic complications are considered among the main extrapulmonary manifestations of coronavirus disease 2019 (COVID-19). The optimal type and duration of prophylactic antithrombotic therapy in these patients remain unknown.

Methods: This article reports the final (90-day) results of the Intermediate versus Standard-dose Prophylactic anticoagulation In cRitically-ill pATIents with COVID-19: An opeN label randomized controlled trial (INSPIRATION) study.

Evaluation of cardiomyopathy diagnosis in heart transplant recipients: comparison of echocardiographic and pathologic classification.

Background: Definite diagnosis of cardiomyopathy types can be challenging in end-stage disease process. New growing data have suggested that there is inconsistency between echocardiography and pathology in defining type of cardiomyopathy before and after heart transplantation. The aim of the present study was to compare the pre-heart transplant echocardiographic diagnosis of cardiomyopathy with the results of post-transplant pathologic diagnosis.

Effect of Intermediate-Dose vs Standard-Dose Prophylactic Anticoagulation on Thrombotic Events, Extracorporeal Membrane Oxygenation Treatment, or Mortality Among Patients With COVID-19 Admitted to the Intensive Care Unit: The INSPIRATION Randomized Clinical Trial.

Importance: Thrombotic events are commonly reported in critically ill patients with COVID-19. Limited data exist to guide the intensity of antithrombotic prophylaxis.

Objective: To evaluate the effects of intermediate-dose vs standard-dose prophylactic anticoagulation among patients with COVID-19 admitted to the intensive care unit (ICU).

Preemptive non-selective bronchial artery angioembolization to reduce recurrence rate of hemoptysis.

Background: Massive hemoptysis which is presented in advanced lung diseases is a life-threatening condition. Bronchial artery embolization as a minimally invasive procedure is the treatment of choice either in first or recurrent hemoptysis. This study aimed to assess the early and late efficacy of bronchial angioembolization (BAE) without microcatheter.
