Background: The effects of left ventricular (LV) diastolic function are well known in cardiac

Pregnancy with complete atrioventricular block is rare, and its perioperative management is controversial. We successfully managed cesarean section in a pregnancy with acquired complete atrioventricular block under spinal anesthesia without a pacemaker. Asymptomatic pregnant women with acquired complete atrioventricular block can tolerate cesarean section under spinal anesthesia without a pacemaker.

Transcatheter aortic valve implantation (TAVI) is a new standard treatment for severe, symptomatic patients [1][2][3][4][5][6][7]. TAVI was initially restricted to high-risk inoperable patients for surgical aortic valve replacement [1,2]. Evidence supporting TAVI use, especially trans-femoral TAVI (TF-TAVI), has led to its application in patients with lower risk [8,9]. In these patients, preventing procedure-related adverse events is crucial. One of the most common adverse events during the procedure is cerebral ischemia [2,3,10,11], as there is a high risk of disruption of vascular plaques or calcified debris of the aortic valve, leading to new sparse ischemic regions in the brain [12][13][14][15]. Several studies have investigated serial patterns of micro-embolization, high-intensity transient signals (HITS), and cerebral damage using transcranial Doppler (TCD) [15][16][17][18]. However, there have been no reports to date assessing procedural patterns of HITS during TAVI by monitoring blood flow in cervical arteries. The aim of this study was thus to investigate the incidence, rate, sequential pattern, and risk factors of HITS during TF-TAVI. Materials and methods Study population and designThe study was a prospective, single-center observational study. In total, 128 consecutive patients who underwent TAVI at Teikyo

An 87-year-old man with worsening functional mitral regurgitation underwent transcatheter mitral valve repair under general anesthesia. Intraoperatively, we administered fluid aggressively to induce mitral regurgitation that had been reduced after anesthesia induction. Subsequently, cardiac dilatation due to the excessive fluid and device irrigation made it difficult to capture the mitral valve leaflets. Diuretics and catecholamines were required for several days after the procedure. Mitral regurgitation during transcatheter mitral valve repair should be induced with vasoconstrictors rather than through fluid administration.
