Implication

Supports further investigation of pulmonary-artery angiocardiography for left atrial thrombi in mitral stenosis; does not yet establish preoperative reliability.

Key Points

To evaluate the efficacy and diagnostic reliability of pulmonary-artery angiocardiography for detecting left atrial thrombi prior to surgery in patients with mitral stenosis.
Retrospective review of medical and radiographic records of 113 patients with predominant mitral stenosis.
All patients underwent cardiac catheterization alongside pulmonary-artery angiocardiography prior to surgical intervention.
Pulmonary-artery angiocardiography identified left atrial intracavitary thrombi to assist in selecting surgical techniques and evaluating operative risk.
A prior clinical history of systemic embolization did not reliably predict the presence of a left atrial thrombus.
