Objectives In patients with symptomatic aortic valve disease who are at intermediate to high risk for open surgical aortic valve replacement, transcatheter aortic valve replacement (TAVR) decreases overall mortality and improves quality of life. Hypertension (HTN) after TAVR has been associated with improved cardiac function and short-term survival but its effect on survival over 1 year is unclear. Our study aims to evaluate the effect of HTN following TAVR on short-term and long-term clinical and echocardiographic outcomes
Methods A retrospective chart review case–control study of 343 consecutive patients who underwent TAVR between August 2012 and November 2016 was performed to elucidate the relationship between HTN and post-TAVR outcomes.
Results 193 patients who underwent TAVR (56.2%) developed or had a worsening of their HTN after TAVR. The development of post-TAVR HTN was associated with a significantly better overall survival at 1 year (89% vs 67%, p<0.001) and 2 years (72% vs 46%, p=0.002). Patients with increased blood pressure also had a significant lower in hospital cardiovascular mortality (1% vs 12%, p<0.001). However, the development or worsening of their HTN after TAVR was associated with an increase in heart failure (HF) exacerbations and diuretic use.
Conclusions The development or worsening of HTN after TAVR is associated with improved overall survival despite an increase in postprocedural HF exacerbations and antihypertensive medication utilisation. The outcomes of this study could be important in postoperative management of patients who underwent TAVR.
