“…Only a few of these patients were operated on by themselves but the process of reviewing the results prompted a technical paper about PEARS — ‘how to implant it’ — which should be required reading for any surgeons embarking on a PEARS programme [12 ▪▪ ]. The illustrations provided by Kenny et al are superb [23 ▪▪ ]. Figs.…”

“…There was an inadvertent ‘proof of concept’ experiment. The surgeon had decided against completing the operation according to the manufacturer's instructions for use [23 ▪▪ ] and instead of dissecting the aorta down to the aorto-ventricular junction, he cut the personalised sleeve and discarded the portion intended to support the sub coronary root. The unsupported aorta progressively dilated in that segment and aortic valve regurgitation ensued.…”

Purpose of reviewTo bring together and annotate publications about personalised external aortic root support reported in the 18 months preceding submission.Recent findingsThe total number of personalised external aortic root support (PEARS) operations is now approaching 700 in 30 centres in Australia, Belgium, Brazil, Czech Republic, Great Britain, Greece, Ireland, Malaysia, Netherlands, New Zealand, Poland and Slovakia. There are continued reports of stability of aortic dimensions and aortic valve function with the only exceptions known being where the surgeon has deviated from the instructions for use of the device. The median root diameter of Marfan patients having PEARS was 47 mm suggesting that the existing criterion of 50 mm is due for reconsideration. The peri-operative mortality currently estimated to be less than 0.3%. The first recipient remains alive and well after 18 years. The use of PEARS as an adjunct to the Ross operation to support the pulmonary autograft is being explored in several centres.SummaryThe operation requires proctoring and adherence to a strict operative protocol and with those precautions excellent results are attained. The evidence and opinions provided in the cited publications indicate that PEARS is a proven and successful prophylactic operation for aortic root aneurysm.
