3D Echocardiographic and Computed Tomographic Angiography Guidance for Percutaneous Closure of a Type II (Intermediate) Aortopulmonary Window.

A 4-year-old female was diagnosed with Type II Aortopulmonary window after being seen for a murmur. By utilizing multimodality advanced imaging, including 2D and 3D echo, computed tomography (CTA) with semi-transparent overlay as a road map, we were able to preoperatively plan camera angles and device selection as well as close the defect percutaneously under echocardiography guidance. This report highlights the importance of a multimodality imaging approach to interventional procedures.

A rare disease detected in a school-age child aortopulmonary window with anomalous right coronary artery from the pulmonary artery.

Aortopulmonary window is a condition characterized by a communication between the pulmonary artery and the ascending aorta. The coexistence of aortopulmonary window and an anomalous right coronary artery originating from the pulmonary artery is rarely observed together, as mentioned in previous studies. In this report, we aim to describe our diagnostic and treatment experiences with a 6-year-old patient diagnosed with aortopulmonary window associated with an abnormal origin of the right coronary artery from the pulmonary artery.

A rare coexistence: Hammock mitral valve and aortopulmonary window.

Congenital mitral stenosis is a broad-spectrum pathology in which blood flow to the left ventricle is obstructed both functionally and anatomically. Hammock mitral valve, also known as anomalous mitral arcade, is a rare congenital anomaly particularly in infants and children. Hammock mitral valve may not be suitable for repair regarding the advanced dysplastic mitral valve structure. Aortopulmonary window is an unusual cardiac anomaly which is defined as a communication between the main pulmonary artery and the ascending aorta. As a result of the excessive left-to-right shunt, early intervention and surgical closure deemed mandatory to avoid development of severe pulmonary hypertension and its consequences. All patients with an aortopulmonary window necessitates prompt repair immediately. In this brief report, mitral valve replacement with a mechanical valve and repair of aortopulmonary window with a Dacron patch were performed simultaneously in a 5-month-old patient with a hammock mitral valve and accompanying aortopulmonary window.

Interrupted Aortic Arch Associated With Aortopulmonary Window: The Role of Multidetector Computed Tomography Angiography.

We report a case of a 2-day-old male with a diagnosis of interrupted aortic arch combined with aortopulmonary window suspected through echocardiography and confirmed by multidetector computer tomography (MDCT) angiography. Our case highlights how MDCT angiography was a key factor in planning surgical approach as it not only accurately defined aortic arch anatomy but also aortopulmonary window morphology.

Evaluation of aortopulmonary window using virtual dissection of multidetector computed tomography angiography data sets.

AIM: The present study sought to evaluate the morphology and associated cardiovascular anomalies in patients with aortopulmonary window on virtual dissection of multidetector computed tomography (CT) angiography data sets. MATERIAL AND METHODS: We conducted a retrospective search of our departmental database from January 2014 to September 2021 to identify patients with aortopulmonary window and relevant information was extracted from the electronic case records and from routine examination as well as virtual dissection of CT data sets. RESULTS: An aortopulmonary window was observed in 26 patients (20 males; 6 females). Based on location of the defect, a distal aortopulmonary window was the most common subtype, seen in 13/26 (50%) patients followed by a proximal, complete and intermediate subtypes seen in 7/26 (27%), 5/26 (19%) and 1/26 (4%) patients respectively. Associated ventricular septal defect was observed in 9/26 (34.6%) patients while an interrupted aortic arch was present in 5/26 (19.2%) patients. Tetralogy of Fallot was seen in 5/26 (19.2%) patients. Anomalous origin of right pulmonary artery from ascending aorta and crossed pulmonary arteries were seen in 2/26 (7.6%) patients each. An isolated aortopulmonary window without any simple/complex congenital anomaly was seen in 10/26 (38.5%) patients. CONCLUSION: Aortopulmonary window is associated with a wide gamut of cardiovascular lesions, with ventricular septal defect being the commonest associated anomaly followed by tetralogy of Fallot and interrupted aortic arch respectively. Virtual dissection of multidetector CT angiography allows detailed anatomical evaluation of aortopulmonary window, allowing a clear visualization of the defect and associated cardiovascular anomalies.

Aortopulmonary window with anomalous ascending aortic origin of left pulmonary artery: Hitherto unreported pattern.

Anomalous ascending aortic origin of left pulmonary artery in association with aortopulmonary window has not been reported so far in literature and is the main highlight of the present case.

Aortopulmonary window and coronary anatomy - still a pre-operative diagnostic trouble!

We present a case of aortopulmonary window in which the diagnosis of anomalous left coronary artery originating from pulmonary artery was made intra-operatively even if the coronary arteries anatomy was correctly studied pre-operatively with echocardiography. No evidence of coronary anomalies or indirect sings of coronary anomalies has been noted. Should we improve our pre-operative diagnostic accuracy and how?

Unique Association of Aortopulmonary Window With Anomalous Origin of Left Coronary Artery From Pulmonary Artery in an Infant: A Blessing in Disguise?

Aortopulmonary window (APW) seen in association with anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is extremely uncommon. When faced with this combination, ALCAPA usually goes undetected since most of the clinical and echocardiographic features of ALCAPA, including ventricular dysfunction are absent due to co-existent pulmonary hypertension. Herein we report a 5-month-old child with a large APW in whom a preoperative computed tomography angiogram facilitated the diagnosis of ALCAPA. The case is described for its rarity and the challenges faced during management. Also, it is extremely crucial that this coronary anomaly is identified and corrected during surgery, since failure to do so results in unforeseen postoperative ventricular dysfunction.

An unusual case of aortopulmonary window with crossed pulmonary arteries.

We report a case of a 4-year-old boy with a distal type of aortopulmonary window with crossed arrangement of the pulmonary arteries. This case highlights the potential clinical implications of this variant pulmonary arterial anatomy in the setting of the aortopulmonary window and the role of computed tomography angiography in accurately defining vascular relationships in patients with complex congenital cardiac defects.

Surgical Management for Late Presentation of Interrupted Aortic Arch with Aortopulmonary Window.

We report a case of advanced age at presentation of interrupted aortic arch with aortopulmonary window. Although the association between these two defects is well established, their overall prevalence is extremely low. This case presents us with an excellent opportunity to discuss decision making regarding aortic arch repair techniques according to age at which primary surgical correction is intended.

A prenatal diagnosis of unusual aortopulmonary communication: tubular aortopulmonary window.

We described a very rare case of aorto-pulmonary communication with right aortic arch and crossed pulmonary artery that cannot be placed in the typical anatomic classification of aortopulmonary window. At 23 weeks gestation, fetal echocardiography revealed a large tunnel-like communication connecting the great vessels proximal to the main pulmonary artery bifurcation, rather than a classic aortopulmonary window between the ascending aorta and the main pulmonary artery.

Total Anomalous Pulmonary Venous Connection and Aortopulmonary Window: Successful Management of a Rare Association.

The association of total anomalous pulmonary venous connection (TAPVC) with aortopulmonary window (APW) is extremely rare. The coexistence of these two anomalies will have implications on clinical presentation, diagnosis, and pathophysiology. The lungs are exposed to pulmonary venous hypertension due to obstructed TAPVC as well as pulmonary arterial hypertension due to unrestrictive APW. We describe successful management of this unusual association in a three-month-old child.

Rerouting anomalous coronary artery origin in aortopulmonary window in newborn.

Coronary artery anomalies may accompany the aortopulmonary window and, if not noticed, may cause catastrophic consequences. The repair of the aortopulmonary window is quite straightforward; however, establishing a normal coronary pattern may challenge the repair. When the anomalous origin of the coronary artery is on the defect rim, right at the location where sutures are to be placed, it may interfere with proper suture placement. A technique to overcome such a technical obstacle and reroute the anomalous right coronary in such cases is described.
