“…Bicuspid aortic valve disease using diastolic reconstructions, supplemented by systolic reconstructions when appropriate, according to Alkhadi et al, awarding 1 point in case of bicuspid valve, and 0 points in case of tricuspid valve 34 . Coronary height was measured according to Gooley et al, yielding 1 point in case of height ≤ 10 mm, and 0 points in case of height > 10 mm 35 . Ilio-femoral calcification was appraised according to Okuyama et al, awarding 2 points in case of moderate or severe calcification, 1 point in case of mild calcification, and 0 points in case of no calcification 36 .…”

Transcatheter aortic valve implantation (TAVI) requires thorough preprocedural planning with non-invasive imaging, including computed tomography (CT). The plethora of details obtained with thoraco-abdominal CT represents a challenge for accurate and synthetic decision-making. We devised and tested a comprehensive score suitable to summarize CT exams when planning TAVI. An original comprehensive scoring system (TAVI-CT score) was devised, including details on cardiac, aortic, iliac and femoral artery features. The score was applied to a prospectively collected series of patients undergoing TAVI at our institution, driving decision making on access and prosthesis choice. Different TAVI-CT score groups were compared in terms of procedural success, acute complications, and early clinical outcomes. We included a total of 200 undergoing TAVI between February 2020 and May 2021, with 74 (37.0%) having a low (0–2) TAVI-CT score, 50 (25.0%) having a moderate (3) TAVI-CT score, and 76 (38.0%) having a high (≥ 4) TAVI-CT score. Male gender was the only non-CT variable significantly associated with the TAVI-CT score (p = 0.001). As expected, access choice differed significantly across TAVI-CT scores (p = 0.009), as was device choice, with Portico more favored and Allegra less favored in the highest TAVI-CT score group (p = 0.036). Acute outcomes were similar in the 3 groups, including device and procedural success rates (respectively p = 0.717 and p = 1). One-month follow-up showed similar rates of death, myocardial infarction, stroke, and bleeding, as well as of a composite safety endpoint (all p > 0.05). However, vascular complications were significantly more common in the highest TAVI-CT score group (p = 0.041). The TAVI-CT score is a simple scoring system that could be routinely applied to CT imaging for TAVI planning, if the present hypothesis-generating findings are confirmed in larger prospective studies.

few quantitative data on the repair-oriented 3-dimensional anatomy of the aortic root are currently available, which impairs standardization of the surgical technique. 1,11 The aim of the present study is to measure the precise metrics of the normal aortic valve as the standard value for guiding successful surgical repair by using computed tomography. 15 Methods Study PopulationWe retrospectively analyzed the datasets obtained from 264 consecutive patients who underwent cardiac computed A ortic valve-sparing surgery has become one of the popular operational options for the primarily regurgitant valve and/or proximal aortic aneurysm over the last few decades. 1-5 Although outcomes of aortic valve-sparing surgery have improved, 6-8 there remain problems, including intraoperative conversion to aortic valve replacement or recurrence of aortic regurgitation. 9-11 As the aortic root anatomy is too complicated to accurately evaluate only with 2-dimensional methodology, 2,12,13 3-dimensional evaluation is necessary to reveal the underlying mechanism of the aortic regurgitation and to define the predictors of successful surgical repair. 11,12,14 However,
