Aortic Valve Repair (AVRep) appeared to be the first considered in the armamentarium to treat AV disease in children of various ages for the last two decades because of its lifelong durability and reproducibility. Several advantages of AV Rep over techniques of Aortic Valve Replacement (AVR) are identified. Surgical repair strategy should be individualized to the age of the patient depending on aortic root growth potential. New repair techniques developed by innovative surgeons are gradually becoming adopted.

Review Analysis

Literature review analysis is accomplished relating to the alternativeness of aortic valve (AoV) repairs in children of various ages with AoV disease. Long- and midterm results of AoV repairs in children both with severe aortic regurgitation and aortic stenosis are outlined. Several advantages and feasibility of AoV repairs over aortic valve replacement accentuating on the individualization of surgical repair strategy to the age of the patient, durability of the repair depending on material properties, growth potential and geometry of AoV are substantiated.

Midline Sternotomy

Annular rupture is a rare but life-threatening complication of transcatheter aortic valve replacement (TAVR). Mortality rates are high if immediate intervention, most often necessitating surgical repair, is not performed. Herein, we describe an 87-year-old man who, after deployment of TAVR, experienced acute decompensation and required urgent conversion to a midline sternotomy to repair an aortic annular rupture. This case demonstrates an example of a rare but severe complication of TAVR. This report provides an in-depth description of the surgical approach to repair an aortic annular rupture and demonstrates the utility of performing minimally invasive procedures inside a hybrid operating room.

Survival And Growth

Environmental conditions and seedling quality interact to produce complex patterns of seedling survival and growth. Root growth potential (RGP) is one metric of seedling quality that can be rapidly measured prior to planting, but the correlation of RGP and seedling performance is not consistent across studies. Site factors including microsite objects that cast shade and competing vegetation can also influence seedling performance. We examined the effects of RGP, presence/absence of a microsite object, and competition cover on the survival and growth of three native conifers to the Inland Northwest, USA, over 5 years. We found that RGP had no effect on the survival or growth of western larch (Larix occidentalis), Douglas fir (Pseudotsuga menziesii var. glauca), and grand fir (Abies grandis) at a mesic north aspect site and a xeric south aspect site. Comparatively, the presence of a microsite increased the odds of survival by 37% for western larch and 158% for grand fir, while the absence of forb cover increased the odds of survival of western larch by 72% and of grand fir by 26%. Douglas fir was less sensitive to microsites and competition. The strong effects of neighborhood conditions around seedlings help inform silvicultural practices to enhance the establishment of western larch and grand fir, including planting seedlings near shading objects and competition control, while these practices may not be as important for Douglas fir.

Repair Techniques

ObjectivesRetrospective review of early results with aortic valve repair (AVr) techniques.Methods61 consecutive patients underwent AVr surgery at our institutions between 2008 and 2018. 14 patients had a bicuspid aortic valve and 16 had a connective tissue disorder. In 48 patients, aortic regurgitation (AR) was secondary to an aortic root and/or ascending aneurysms, while in 13 it was due to primary cusp pathologies. 13 patients underwent isolated cusp repair, 19 sinotubular junction remodelling, 25 valve-sparing root replacement (VSRR) and 4 hemiroot replacement. Cusp repair techniques included: 18 free margin plication, 18 commissural re-suspensions, 3 raphe resections and 1 free-edge reinforcement. Subcommissural annuloplasty was performed in 25 patients (42%) with a dilated annulus (>28 mm).Results50 patients (82%) left the operating theatre with no AR, 8 with mild central and 3 with mild eccentric AR. In-hospital survival was 100%. Clinical follow-up was complete at 5.08±2.29 years and all patients were alive. Transthoracic echocardiographic follow-up was complete at 2.35±1.92 years and showed the presence of a moderate AR in 10 patients (18%) and severe AR in 2 patients (4%). One of these required re-do aortic valve replacement 6 years after VSRR. Freedom from re-operation at 8 years was 88.15%±1.51%.ConclusionGood early results are achievable following AVr with acceptable medium-term outcomes. AVr surgery continues to evolve, and concentrating the experience in specialist centres in the UK is recommended.
