Background and aims: Pulmonary hypertension (PH) is associated with higher mortality and morbidity after valvular heart surgery, mainly through its adverse effect on right ventricular hemodynamic. Recently, the European Society of Cardiology (ESC) PH guidelines introduced a PH probability grading that lists additional parameters related to right ventricular dimensions. We evaluated the impact of such score on short- and mid-term outcomes in patients undergoing left heart valvular surgery. Methods and results: We included 60 consecutive patients (mean age 70 ± 9 years) undergoing left heart valvular surgery with or without coronary artery bypass. Patients were divided into 3 groups according to the PH probability: “low” (n = 18), “intermediate” (n = 18), or “high” (n = 24). The high PH probability group had higher rate of World Health Organization-Functional Class (WHO-FC) III and IV, hemodynamic complications, deaths, major bleeding events and infections after heart surgery than the other groups. A “high” PH probability was associated with reduced right ventricular systolic function, as measured by the fractional area change (FAC), but not with the tricuspid annular plane systolic excursion (TAPSE). Conclusion: The high PH probability as evaluated by the ESC PH echocardiographic probability model, is associated with increased short- and mid-term mortality and morbidity and reduced right ventricular systolic function after cardiac surgery, Thus, additional echocardiographic parameters assessing PH probability are valuable tools to stratify risk in patients undergoing cardiac surgery.

Abstract

Background and aims: Pulmonary hypertension (PH) is associated with higher mortality and morbidity after valvular heart surgery, mainly through its adverse effect on right ventricular hemodynamic. Recently, the European Society of Cardiology (ESC) PH guidelines introduced a PH probability grading that lists additional parameters related to right ventricular dimensions. We evaluated the impact of such score on short- and mid-term outcomes in patients undergoing left heart valvular surgery. Methods and results: We included 60 consecutive patients (mean age 70 ± 9 years) undergoing left heart valvular surgery with or without coronary artery bypass. Patients were divided into 3 groups according to the PH probability: “low” (n = 18), “intermediate” (n = 18), or “high” (n = 24). The high PH probability group had higher rate of World Health Organization-Functional Class (WHO-FC) III and IV, hemodynamic complications, deaths, major bleeding events and infections after heart surgery than the other groups. A “high” PH probability was associated with reduced right ventricular systolic function, as measured by the fractional area change (FAC), but not with the tricuspid annular plane systolic excursion (TAPSE). Conclusion: The high PH probability as evaluated by the ESC PH echocardiographic probability model, is associated with increased short- and mid-term mortality and morbidity and reduced right ventricular systolic function after cardiac surgery, Thus, additional echocardiographic parameters assessing PH probability are valuable tools to stratify risk in patients undergoing cardiac surgery.
