frozen elephant trunk for aortic arch reconstruction is associated with reduced mortality as compared to conventional techniques
wariber [46]

To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).

<h3>What is Aortic arch ?</h3>

The top portion of the principal artery sending blood away from the heart is known as the aortic arch. A combination of symptoms and signs known as aortic arch syndrome are linked to anatomical issues in the arteries that branch off the aortic arch. The valves, chambers, and accompanying vessels that make up the heart's interior.

Pyruvate is a direct precursor of anapleurotic reactions which produce which intermediates of the tca cycle?
Virty [35]

The correct answer is:  oxaloacetate

Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.

The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.
