Combined assessment of pulmonary artery pulsatility index and pulmonary arterial capacitance for risk stratification following transcatheter aortic valve implantation

Key Result

Combined PAPi-PAC assessment identified distinct haemodynamic phenotypes with prognostic significance following transcatheter aortic valve implantation.

Key Points

• To evaluate the prognostic value of combined PAPi and PAC assessments following transcatheter aortic valve implantation.
• Conducted assessments of pulmonary artery pulsatility index (PAPi) and pulmonary arterial capacitance (PAC) following TAVI.
• Identified distinct haemodynamic phenotypes based on combined PAPi-PAC data.
• Established a framework for individualized postprocedural management.
• Distinct haemodynamic phenotypes were identified, each with unique prognostic implications.
• The combined assessment provided improved risk stratification after TAVI.
