    ObjectiveTo characterize patients with right heart failure undergoing isolated tricuspid valve surgery, focusing on right heart morphology and function.Patients And MethodsFrom January 2007 to January 2014, 62 patients underwent isolated tricuspid valve surgery. Forty-five patients (73%) had undergone previous heart operations. Right heart morphology and function variables were measured de novo from stored echocardiographic images, and clinical and hemodynamic data were extracted from patient registries and records. Cluster analysis was performed and outcomes assessed.ResultsOn average, the right ventricle was dilated (diastolic area 32 cm2), but its function was preserved (free-wall strain -17% ± 5.8%) and right heart failure manifestations were moderate, with 40 (65%) having congested neck veins, 35 (56%) dependent edema, and 15 (24%) ascites. Average model for end-stage liver disease with sodium score was 11 ± 4.4, but individual values varied widely. Tricuspid valve variables split patients into 2 equal clusters: those with functional tricuspid regurgitation (TR) and those with structural TR. These groups had similar right ventricular function, but the functional TR group had worse right ventricular morphology and more severe manifestations of right heart failure, including greater model for end-stage liver disease with sodium scores (12 ± 44 vs 9.1 ± 3.9; P = .008). Both groups survived operation with low morbidity, but patients with functional TR had worse long-term survival, 48% versus 73% at 10 years after surgery.ConclusionsThe cluster analysis of patients with right heart failure undergoing isolated tricuspid valve surgery separated functional and structural tricuspid valve disease. Good early outcomes suggest expanding criteria for tricuspid valve surgery and earlier intervention for functional TR with right heart failure.Copyright © 2021 The American Association for Thoracic Surgery.
