“…Venous contrast echocardiography can provide grounds for suspicion about the presence of an arteriovenous fistula, although the origin or place of a fistula cannot be specified with this technique. 7,16,19,26 This is why it is very important to consider the speed with which micro-bubbles appear in the left atrium. As can be seen in case 2 (Fig 6), the bubbles appeared almost simultaneously in the right atrium, right ventricle, and left atrium.…”

“…2 This pathology has been considered a variant of pulmonary arteriovenous fistula, 6 and delay in diagnosing it leads to severe complications caused by hypoxia, mainly by neurologic complications such as cerebral abscesses, cerebrovascular accidents, or systemic embolisation caused by paradoxical embolism. 7,8 As remarked in several publications, diagnosis can be easily missed, and this -associated with the few published cases -explains why this pathology is not taken into consideration.…”

“…Most of these cases have been described after the first decade of life and the oldest patient recorded so far was 60 years old; fewer patients have been diagnosed during childhood and/or during the neonatal period, and only 10 cases have been published for the latter group 2 . This pathology has been considered a variant of pulmonary arteriovenous fistula, 6 and delay in diagnosing it leads to severe complications caused by hypoxia, mainly by neurologic complications such as cerebral abscesses, cerebrovascular accidents, or systemic embolisation caused by paradoxical embolism 7 , 8 .

Right pulmonary artery to left atrial fistula is a rare pathology characterised by a right to left shunt. Another important aspect of this pathology is the difficulty encountered in making a diagnosis, which is why the diagnosis is frequently delayed into adulthood. A description of two cases is used to emphasise the importance of the different modes of echocardiography as a diagnostic tool in diagnosis, as well as the two different clinical forms that it adopts: a group of patients suffering cardiac failure and cyanosis without apparent cause generally in neonates and a second group of mostly older patients with dyspnoea and cyanosis without apparent cause. Symptoms thus differ depending on the time of presentation and are related to the size of the fistula.

“…The report of a rare case of right pulmonary artery (PA) to left atrial (LA) fistula by Faizal and colleagues 1 is very interesting. The authors performed transthoracic echocardiography with contrast injection in a peripheral vein.…”

This is a collective review of 59 published cases of right pulmonary artery to left atrium communication in the English-language literature. In this article, we review the literature on the clinical presentation, anatomic variations, diagnostic features, and management considerations of previously reported cases. Two-dimensional echocardiography and cardiac catheterization including selective angiography provided the necessary diagnostic information and defined the anatomy before surgery in all patients. Various management options including medical, surgical, and transcatheter closure have been reported. The lesions have been classified into four types (I, II, III, and IV) that have a bearing on the appropriate surgical approach and techniques of repair that are discussed in the text. Use of extracorporeal circulation may be considered in selected instances. The operative mortality rate during the earlier era (1950 to 1979) was high, at 22%. More recently, the mortality rate has approached zero. An individualized surgical approach depending on the type of surgical connections is recommended.
