Description
Sachiyo Igata and co-authors measured timing spread in the right heart chamber in 2026 in 30 patients with high pressure in the lung arteries from narrowed vessels. Scans, ultrasound speckle tracking, and direct pressure readings through a catheter were combined in one visit.
Wider timing spread tracked with higher artery pressure and higher flow resistance, and with weaker matching between chamber and artery. After adjustment, artery pressure alone predicted the spread, covering about a quarter of its variation. Chamber size and pumping share did not. Dyssynchrony appeared even when chamber function was only mildly reduced. The authors propose the ultrasound measure as a stand-in for invasive pressure checks.
