   Introduction Top


Tetralogy of Fallot (TOF) is the most common congenital heart disease with survival to adulthood. Infective endocarditis accounts for 1.7-6.2 cases per 100,000 in the Western world but such estimates are not available from India for patients with a congenital heart lesion. [1] This report is unique in that an embolic lesion of the main pulmonary artery (MPA), probably of infective etiology, was noted in a child with TOF.


   Case Report Top


An unusual association of TOF and bacterial endocarditis of the MPA is presented.


   Conclusion Top


In this case report, the diagnostic implications and therapeutic consequences of TOF with infective endocarditis are discussed. In addition, this case report emphasizes the use of transesophageal echocardiography (TEE) in patients with congenital heart disease for shunt surgery. The risk of a coincident infective endocarditis in patients with congenital heart disease is highlighted, and the need for careful attention to this possibility during intraoperative evaluation of such patients emphasized, especially if it has been overlooked in the preoperative data!

A 7-year-old male known case of TOF presented to emergency room with a history of cyanotic spells. On the basis of clinical examination, he was cyanosed and was not able to maintain saturation, thus intubated and was planned to shift to operation room for emergency central shunt. Primary examination of transthoracic echo or angiography was not done; however, old echo confirmed the diagnosis of TOF. Detailed intraoperative examination of TEE revealed a large perimembranous ventricular septal defect (VSD) of 1.52 mm, overriding of aorta more than 50% [Figure 1] and to our surprise a vegetation in MPA, measuring 1.67 mm × 0.735 mm [Figure 2] and [Figure 3], which is a rarity. Continuous-wave Doppler showed a gradient of 40 mmHg across VSD [Figure 4]. The child was extubated after 5 days following recovery from pneumonia and discharged from the hospital on the 20 th postoperative day, after full recovery. On the first follow-up visit, he had no complaints. His histopathology and culture report confirmed the diagnosis of bacterial endocarditis.

Echocardiography plays a key role in the diagnosis of infective endocarditis, its complications, follow-up evaluation after therapy, and prognostic assessment. [2],[3] This report describes patient with TOF with vegetations in MPA who presented with cyanotic spells. This case illustrates and reiterates the important role of TEE in diagnosis of intraoperative infective endocarditis lesion in providing hemodynamic data and helped to review the surgical discussion of the central shunt and converted the case into total correction and gave a new lease of life to the patient. It was being overlooked as an artifact otherwise. TEE intraoperatively in TOF is a must. [4]
