Key result

Combined pulmonary artery pulsatility index (PAPi) and pulmonary arterial capacitance (PAC) phenotyping after TAVI provides important prognostic insights.

Key Points

To discuss interpretive and translational considerations regarding the prognostic utility of pulmonary artery pulsatility index (PAPi) and pulmonary arterial capacitance (PAC) following transcatheter aortic valve implantation (TAVI).
Evaluation and commentary on the hemodynamic findings and prognostic implications reported by Ozaki et al.
Synthesis of physiological mechanisms linking right ventricular performance, pulmonary compliance, and post-TAVI outcomes.
Simultaneous phenotyping using PAPi and PAC provides comprehensive assessment of right ventricular-pulmonary vascular coupling.
Combined metric analysis improves post-procedural risk stratification compared to evaluating either parameter in isolation.
