In this study we describe the echocardiographic features of a complex cardiac defect with a right to left shunt through tetralogy of Fallot and also a left to right shunt through a patent ductus arteriosus (PDA) in a 3-year-old dog. The echocardiography revealed a tetralogy of Fallot with a severely hypertrophied right ventricular outflow tract (RVOT), and a left to right shunting PDA. A contrast echocardiogram showed microbubbles moving from the right ventricle to the aorta through the ventricular septal defect. They then reached the main pulmonary artery through the PDA rather than through the RVOT. The necropsy confirmed tetralogy of Fallot with an RVOT obstruction and a PDA. This patient could have maintained the pulmonary circulation through the PDA in the spite of the right ventricular outflow tract obstruction and survive a long period. Not only the echocardiography, but also the contrast echocardiogram using agitated saline and trans-sectional images in CT enhanced the comprehensive understanding of the anatomic defects in this complex cardiac defect.

Ventricular Outflow Tract Obstruction

Unruptured right sinus of Valsalva aneurysm that causes severe obstruction of the right ventricular outflow tract is extremely rare. We describe the case of a 47-year-old woman who presented with exertional dyspnea. Upon investigation, we discovered an unruptured right sinus of Valsalva aneurysm with associated right ventricular outflow tract obstruction and a supracristal ventricular septal defect. To our knowledge, only 2 such cases have previously been reported in the medical literature. Although treatment of unruptured sinus of Valsalva aneurysm remains debatable, surgery should be considered for extremely large aneurysms or for progressive enlargement of the aneurysm on serial evaluation. Surgery was undertaken in our patient because there was clear evidence of right ventricular outflow tract obstruction, right-sided heart dilation, and associated exertional dyspnea.

AbstractWe present the case studies of two adult patients with tetralogy of Fallot who were scheduled for surgery. After addressing the right ventricular outflow tract obstruction, the aorta was opened and the ventricular septal defect was approached in a straightforward manner as it was located just under the overriding aortic valve. The second patient presented with was a situs inversus, dextroapex Fallot. In this setting, the aortic approach simplified the repair expeditiously. After 2 years, both patients are in New York Heart Association class I, with no residual ventricular septal defect, no aortic regurgitation, and complete relief of right ventricular outflow tract obstruction.
