Concomitant valve-sparing aortic root replacement with tetralogy of Fallot repair in a 30-year-old patient: A case report.

Int J Surg Case Rep 2021 May 29;82:105930. Epub 2021 Apr 29.

Adult Cardiac Surgical Intensive Care Unit, Hanoi Heart Hospital, Hanoi, Viet Nam.

Introduction And Importance: Aortic regurgitation and aortic root dilatation are common features in adults with both repaired and unrepaired tetralogy of Fallot (TOF). Valve-sparing aortic root replacement (VSARR) is an effective repair for aortic regurgitation due to progressive aortic root dilatation with TOF after repair. However, the effectiveness of this technique for unrepaired patients has rarely been reported.

Case Presentation: We reported a case of a 30-year-old man with cyanosis and exertional dyspnea. Echocardiography and computed tomography showed unrepaired TOF with significant aortic regurgitation and massively dilated aortic root. Aortic root replacement was mandatory. He underwent successful concomitant VSARR with TOF repair. At 6-month follow-up, he remains stable with trivial aortic regurgitation on echocardiogram.

Clinical Discussion: In unrepaired TOF, the absence of sub-annular muscular rim and the unbalance of aortic sinuses make VSARR utmost challenging. If can be done successfully, VSARR preserves the native aortic valve and avoids lifelong anticoagulation therapy.

Conclusion: Concomitant VSARR with TOF repair can be safely and effectively applied for unrepaired patients presenting with progressive aortic root dilatation and significant aortic regurgitation.

Fruit characteristics, phytochemical and antioxidant properties of blueberry ash ().

Heliyon 2018 Oct 5;4(10):e00834. Epub 2018 Oct 5.

Blueberry ash ( Sm.) fruit has potential for human nutrition, but there is limited information on this fruit. This preliminary study aimed to characterise blueberry ash fruit and examine the influence of extraction solvents on its phytochemical and antioxidant properties. Blueberry ash fruit is dark blue in colour and is a stone fruit of small size (7 mm) and light weight (0.2 g). However, it has a high portion of flesh (60% of fruit weight), which is edible and can be a potential source of phytochemicals. Water, ethanol, acetonitrile, acetone, and their combination were tested for extraction of phytochemicals from flesh of this fruit. Water or absolute organic solvent was ineffective for extraction of phenolic compounds from this fruit, but mixtures of water and organic solvents were more effective, and 50% acetone was the most suitable extraction solvent. Extraction with 50% acetone, this fruit was found to contain high levels of total phenolic content, flavonoids, proanthocyanidins, and anthocyanins (104 mg GAE/g, 155 mg RUE/g, 78 mg CE/g, and 119 mg CGE/g, respectively). In addition, this fruit was found to possess potent antioxidant properties. Therefore, this fruit should be further studied for identification of its phenolic compounds and further tested for their biological properties.
