Abstract
BACKGROUND
Takotsubo syndrome (TTS) has been reported in solid-organ transplant recipients. However, the pooled data regarding TTS after liver transplant remain limited.
METHODS
A systematic review was performed through February 2022 using PubMed, Embase, Scopus, and Google Scholar to review case reports/series and original studies on liver transplant-associated TTS. Descriptive analysis was performed for case reports and pooled analysis for the prevalence using random effects models.
RESULTS
A total of 56 case reports were included from 30 articles (51.8 % male; mean age, 53 years; India 56%, US 27%, and Europe 8.93%) and 10 original studies (US 88.65%, India 10.92%) revealing liver transplant-associated TTS. The pooled prevalence of TTS was 1.1% (95% Cl, 0.6%-1.7%) of all liver transplants with comparable rates in studies from India and the US (P = .92). Indications for liver transplant included end-stage liver disease due to alcohol-related cirrhosis (25%), hepatitis C virus infection (17.9%), hepatocellular carcinoma (10.7%), and non-alcohol-related steatohepatitis (8.9%); the average Model for End-Stage Liver Disease score was 24.75. TTS commonly presented as hypotension (30%), dyspnea (14%), and oliguria, occurring mostly post-transplant (82%), whereas 14% were intraoperative. Common electrocardiogram findings were ST changes, ventricular tachycardia, and atrial fibrillation. Common echocardiogram findings showed left ventricular apical ballooning in 46.5% of cases and reduced ejection fraction < 20% in 41.9% of cases. Common complications were cardiogenic shock (32.1 %), acute kidney injury (12.5%), arrhythmia, stroke, cardiac arrest, and hepatic artery thrombosis. Mechanical circulatory support was required in 30.3%. Recurrence was reported in 15, and mortality in 30.4% of patients.
CONCLUSIONS
Takotsubo syndrome prevalence after liver transplant is significantly higher than TTS prevalence in general US hospitalizations with potentially worse outcomes. Prospective registries reporting TTS in liver transplant recipients are warranted.
