BACKGROUND. Heart failure (HF) is an uncommon complication after TIPS placement; its development represents a poor prognostic factor. OBJECTIVE. The purpose of our study was to evaluate the frequency, risk factors, and association with survival of HF developing within 90 days after TIPS placement in patients with cirrhosis. METHODS. This retrospective single-center study included patients with cirrhosis who underwent nonemergent covered-stent TIPS placement from June 2003 to December 2018 and who underwent echocardiography within 2 months before TIPS placement and had at least 90 days of post-TIPS follow-up. Development of HF within 90 days after TIPS was recorded. Frequency of TIPS reduction for post-TIPS HF was determined. Univariable logistic regression analysis and ROC curve analysis were performed to assess potential risk factors for post-TIPS HF. Association of post-TIPS HF and 1-year survival was assessed by the log rank test. RESULTS. The study sample included 107 patients (71 men and 36 women; median age, 58 years). Post-TIPS HF developed in 11 of 107 (10%) patients; median time to development of HF was 16 days (range, 2-62 days). Of these 11 patients, three (27%) required TIPS reduction to achieve resolution of HF symptoms after unsuccessful diuretic therapy. Pre-TIPS right atrium size (odds ratio [OR], 3.26 [95% CI, 1.22-10.16]; p = .03], left ventricle (LV) end-systolic dimension (OR, 5.43 [95% CI, 1.44-24.50], p = .02), LV end-diastolic dimension (OR, 4.12 [95% CI, 1.51-13.47]; p = .009), and estimated peak pulmonary artery systolic pressure (PASP) (OR, 1.27 [95% CI, 1.12-1.50]; p = .001) were associated with post-TIPS HF. AUC of right atrium size, LV end-systolic dimension, LV end-diastolic dimension, and estimated peak PASP for development of post-TIPS HF were 0.71, 0.74, 0.72, and 0.83, respectively. At a cutoff of 31 mm Hg, PASP achieved sensitivity of 70% and specificity of 86% for post-TIPS HF. Patients with post-TIPS HF and those without post-TIPS HF had 1-year survival of 46% versus 73% (p = .06). CONCLUSION. Multiple pre-TIPS echocardiographic variables predict the development of post-TIPS HF in patients with cirrhosis. CLINICAL IMPACT. Preprocedural echocardiography may guide risk stratification in patients with cirrhosis being considered for TIPS placement.
