Abstract Background Relative apical sparing pattern (RASP) is thought to be associated with prognosis in patients with cardiac amyloidosis or left ventricular hypertrophy (LVH). Although almost all patients with severe aortic stenosis (AS) have LVH, little is known about the effect of transcatheter aortic valve implantation (TAVI) in patients with severe AS exhibiting a RASP. Purpose This study aimed to elucidate the effect of TAVI on left ventricular global longitudinal strain (LS; LVGLS) in patients with severe AS exhibiting a RASP. Methods Eighty-four patients who underwent transfemoral or subclavian TAVI were evaluated. They were divided into the RASP and non-RASP groups. The average apical LS divided by the sum of the average mid and basal LS values of >1.0 was defined as the RASP. We analyzed the difference between pre- and post-TAVI LVGLS (ΔGLS = post-TAVI LVGLS − pre-TAVI LVGLS). Results Of the 84 patients (mean age, 84.5±3.9 years; 24 men), 15 (17.9%) exhibited a RASP. No significant difference in mean pre-TAVI LVGLS was found between the RASP and non-RASP groups (−16.6% ± 3.8% vs. −15.8% ± 3.9%). The ΔGLS in the RASP group was significantly higher than that in the non-RASP group (−0.97% ± 2.5% vs. −2.6% ± 3.0%; P<0.05). Multivariate analysis revealed that relative apical longitudinal strain was an independent predictor of ΔGLS (β = 0.35, p=0.002). Conclusion Relative apical longitudinal strain was associated with LVGLS recovery. The effect of TAVI on LVGLS in patients with a RASP is inferior to that in patients without a RASP.

Abstract Background Increasing number of symptomatic patients with severe aortic stenosis is treated with transcatheter aortic valve implantation (TAVI). Stroke is one of the most serious complications of TAVI, and the majority of cerebral events in patients undergoing TAVI have an embolic origin. Case summary A 90-year-old female underwent trans-femoral TAVI for symptomatic severe aortic stenosis. Just before the implantation of the transcatheter heart valve (THV), transoesophageal echocardiography (TOE) showed a mobile, high-echoic mass attached to the THV, which gradually enlarged to 26 mm, then spontaneously detached from the THV and flowed up the ascending aorta, disappearing from the TOE field of. After the procedure, the patient presented with ischaemic stroke. The patient’s stroke was thought to have resulted from the embolism migrating to the distal cerebral arteries. Discussion The detailed images acquired with TOE during TAVI enabled the prompt identification of the unusual intracardiac mass.
