title: Analysis of benign ventricular tumors: long-term outcome after resection.
abstract: OBJECTIVE
  We sought to compare clinical and pathologic characteristics of ventricular tumors and to detect whether differences exist in short- and long-term survival after resection.
  
  
  METHODS
  From 1964 to 2005, 323 patients had cardiac surgery for resection of primary cardiac tumors; 53 (16%) patients had primary ventricular tumors. We randomly sampled 53 characteristics of ventricular tumors.
  
  
  RESULTS
  Patients with ventricular tumors were younger than those with atrial tumors (34.8 vs 54.6 years; P < .0001). New York Heart Association functional status was similar at presentation, although patients with atrial tumors had increased risk of atrial fibrillation (P < .05), thromboembolic events (P = .04), and mitral stenosis (P = .008) at the time of presentation. Patients with ventricular tumors had an increased incidence of myocardial invasion (14% vs 2%; P = .02) and had significantly longer cardiopulmonary bypass (80 vs 65 minutes; P < .05) and crossclamp (52 vs 39 minutes; P = .03) times. Operative mortality was 4% and 0% in the ventricular and atrial groups, respectively (P = not significant). Follow-up was obtained in 89% of patients at a mean follow-up time of 7.21 years. A Kaplan-Meier survival plot demonstrated no difference in survival characteristics of both groups. At follow-up, 81% and 74% of ventricular and atrial tumors, respectively, were minimally symptomatic (New York Heart Association class I/II; P = .13). Patients with atrial and ventricular tumors had a 6% and 0% tumor recurrence rate, respectively (P = .12).
  
  
  CONCLUSIONS
  Surgical resection for ventricular tumors is effective and results in excellent long-term outcome. Early surgical treatment should be strongly considered in patients with primary ventricular tumors.
