Comparing HeartModel and cardiac magnetic resonance imaging for left ventricular volume and function evaluation in patients with dilated cardiomyopathy.

Background: Integration of artificial intelligence enhances precision, yielding dependable evaluations of left ventricular volumes and ejection fraction despite image quality variations. Commercial software like HeartModel provides fully automated 3DE quantification, simplifying the measurement of left chamber volumes and ejection fraction. In this manuscript, we present a cross-sectional study to assess and compare the diagnostic accuracy of automated 3D echocardiography (HeartModel) to the standard Cardiac Magnetic Resonance Imaging in patients with dilated cardiomyopathy.

Age-dependent association between aneurysmal and isolated redundant inter-atrial septum with patent foramen ovale.

Background: Interatrial septum (IAS) could be redundant by abnormal movement with or without aneurysmal bulging. We aimed to determine the prevalence of isolated redundant and aneurysmal IAS motion and their probable relationship with age and presence of patent foramen ovale (PFO) in a large-scale referral center.

Method: A total of 15,288 patients who underwent transthoracic echocardiography (TTE) at Tehran Heart Center were included From March 2019 to March 2021.

Assessing the role of anastomotic level in low anterior resection (LAR) surgery among rectal cancer patients in the development of LAR syndrome: a systematic review study.

Background: The etiology of LARS has not been elaborated on clearly. Studies have reported neoadjuvant therapy, low-lying rectal cancers, adjuvant therapy and anastomotic leakage as risk factors for the development of LARS. Anastomotic level has also been proposed as a possible risk factor; However, there have been conflicting results.

Lethal outcome of Covid-19 pneumonia in a new liver recipient with neurological manifestation.

COVID-19 is a new contagious viral pneumonia with various signs and symptoms, including loss of consciousness, liver injury, and cerebrovascular accident; however, there is little data on the manifestation and outcome of COVID-19 in liver transplant patients. Moreover, because transplant units in Iran were closed from the first day of the COVID-19 pandemic, accurate data about nosocomial COVID-19 and the liver transplant setting is not available. In this article, we introduce a liver transplant recipient with a final fatal outcome, who had had neurological manifestations, and whose COVID-19 manifestations began in the hospital within 2 days of transplant surgery.
