Massive left atrial thrombus complicating mitral stenosis with atrial fibrillation: results of surgical treatment
S John, S Muralidharan, PS Jairaj, S Krishnaswamy, IP Sukumar and G Cherian
Thirty-five patients with massive atrial thrombus complicating mitral
stenosis and atrial fibrillation were treated surgically. The mean age in
this series is lower than that reported in the West. Furthermore, the
incidence of preoperative embolic manifestations has been less frequent in
our experience. We believe it is desirable to document the presence of a
thrombus by selective left atrial cineangiography. Surgical treatment was
accomplished with an acceptable mortality. The vital role played by the use
of low-molecular-weight dextran and early anticoagulation in decreasing the
incidence of postoperative cerebral embolism is emphasized. Follow-up data
in the survivors has shown excellent functional status with no late embolic
phenomena in any subject.
