Article Abstract
A 63-year-old female with complex congenital heart disease underwent a classical Blalock-Taussig (B-T) shunt operation at the age of 3 years in 1948. The cardiac morphology was not amenable to further definite surgical repair in that period of time. With this palliative operation, the patient survived to the age of 63 years and now presented with exercise intolerance and significant desaturation. Cardiac catheterization with angiography revealed a severe stenosis of the B-T shunt at the pulmonary end. Balloon dilation and stent implantation could be performed successfully. Follow-up after 5 months showed a patent B-T shunt and an increase of oxygen saturation from 65% to 80% and mild improvement of pulmonary blood flow and exercise tolerance.

Portal Venous Remodeling Determines the Pattern of Cirrhosis Decompensation: A Systems Analysis.
Clin Transl Gastroenterol

Introduction: As liver disease progresses, scarring results in worsening hemodynamics ultimately culminating in portal hypertension. This process has classically been quantified through the portosystemic pressure gradient (PSG), which is clinically estimated by hepatic venous pressure gradient (HVPG); however, PSG alone does not predict a given patient's clinical trajectory regarding the Baveno stage of cirrhosis. We hypothesize that a patient's PSG sensitivity to venous remodeling could explain disparate disease trajectories.

Purpose: To describe a case of late post-surgical sympathetic ophthalmia documented with multimodal imaging.
Observations: A 74-year-old male presented to the urgent care of the New York Eye and Ear Infirmary with blurry vision and discomfort in his left eye for three weeks. His vision was 20/50, with intraocular pressure of 13 mmHg, and slit lamp examination was significant for conjunctival congestion, 1+ anterior segment cell and flare, and diffuse keratic precipitates.

Background: In military trauma, temporary vascular shunts restore arterial continuity until delayed vascular reconstruction, often for a period of hours. A novel US Air Force-developed trauma-specific vascular injury shunt (TS-VIS) incorporates an accessible side port for intervention or monitoring, which may improve patency under adverse hemodynamic conditions. Our objective was to evaluate TS-VIS patency in the setting of volume-limited resuscitation from hemorrhagic shock.

To summarize the experience of arterial duct (AD) stenting in children with ductus-dependent hypoplastic right heart syndrome (HRHS). Seven children including 4 cases of pulmonary atresia with intact ventricular septum (PA-IVS) with HRHS and 3 cases of critical pulmonary stenosis (CPS)-IVS with HRHS underwent AD stenting in Qingdao Women and Children's Hospital between January 2012 and January 2019. During the same period, 9 patients of PA-IVS with HRHS received Blalock Taussig (B-T) shunt.

This method was selected in order to minimize the surgical manipulations in the setting of a critically ill infant.
