Tetralogy of Fallot with rheumatic mitral stenosis: a case report

A rare case of Tetralogy of Fallot with right atrial thrombus presenting with hemiplegia complicating the clinical course

BACKGROUND

Cerebrovascular accidents represent a dangerous complication of cyanotic children with tetralogy of Fallot with the incidence of 8.6%. Tetralogy of Fallot has been associated with raised hematocrit with low arterial saturation.

AIM

Here we describe an 18 months old female child of Tetralogy of Fallot with cyanotic spells acute onset right-sided hemiplegia with right atrial thrombus who underwent emergency surgery with the intraoperative predicament.

MATERIALS AND METHODS

A female child with Tetralogy of Fallot presented to emergency department with acute onset right sided hemiplegia. After hemodynamic stabilization the patient underwent series of investigations and was diagnosed to have thrombus of size in right atrium.

DISCUSSION

Among the few causes causing neurological complications in Tetralogy and Fallot, right atrial thrombus appears to be a rare but possible cause.

CONCLUSION

ntracardiac thrombus can be considered as a cause for embolic neurological events in patients with Tetralogy of Fallot.

Unusual cardiac associations with Tetralogy of Fallot-a descriptive study

We present a large single-center series (>2200 cases) operated for Tetralogy of Fallot (TOF). We analyzed the incidence of associated unusual and uncommonly described cardiac lesions and their diagnostic and therapeutic implications in TOF patients. This retrospective study was conducted by reviewing records of patients operated for TOF at a large tertiary care pediatric cardiac centre. From 2002 to 2008, a total of 2235 cases of TOF were evaluated with echocardiography, cardiac catheterization, and/or cardiac computed tomography followed by cardiac surgery. Known and well-described associations were excluded from the study. Unusual associations were tabulated. Several unusual associations having an incidence >0.1% were detected. These included subaortic membrane (1%), pulmonary venous abnormalities (0.5%), small left ventricle (0.5%), interrupted inferior vena cava (0.5%), mitral valve abnormalities (0.4%), hemitruncus (0.4%), tricuspid valve abnormalities (0.4%), biventricular dysfunction (0.3%), retroaortic innominate vein (0.3%), bicuspid aortic valve (0.2%), and pericardial effusion (0.2%). This series describes unusual, not previously routinely reported cardiac lesions associated with TOF that may affect management and should be sought on preoperative evaluation. We demonstrate that more unusual associations do exist in not infrequent numbers, i.e., a TET is not just a TET.
