We report the case of a successful transatrial hybrid atrial septal defect (ASD II) closure in a borderline 9-month-old girl with multiple congenital defects.
The patient, with hemodynamically significant ASD II, had scoliosis of the thoracic spine with multiple axial skeleton defects, including congenital defects of thoracic vertebrae, defects of the right ribs and agenesis of the sternum (Figure 1 A). Moreover, the patient suffered from overflow pulmonary hypertension, associated with hypoplasia of the right lung, hypotrophy with low body weight and height (< 3 percentile), and obstructive bronchitis (during pharmacological treatment and permanent nasal oxygen therapy). Intragastric tube feeding was carried out from birth. Despite intensive conventional treatment, the girl had permanent mixed inspiratory-expiratory dyspnea, with signs of central cyanosis, reduction of vesicular murmur on the right side, as well as rales and wheezing.
The echocardiographic examination showed dilatation of the right ventricle (RV), right atrium (RA) and pulmonary artery (PA), paradoxical interventricular septal (IVS) motion, normal size and contractility of the left ventricle (LV), with ASD II (8–10 mm width) in the central area of the septum, with massive left-to-right shunt (Qp : Qs > 2.5 : 1), turbulent inflow from pulmonary veins to the left atrium, and elevated systolic pressure of the right ventricle (60–65 mm Hg).
After analysis of the heart defect and hemodynamic effects, with concomitant severe general comorbidities, in the face of clear contraindications to surgery (vascular positional anomalies) as well as to cardiac intervention from peripheral access (small venous diameter), the patient was electively qualified for hybrid transatrial ASD II closure.
The anterior minithoracotomy was made via the 4th intercostal space, where agenesis of the ribs was palpable. The upper lobe of the right lung was naturally expanded, the middle collapsed, and the lower in deep involution. The pericardial sac was opened above the RA in front of the right phrenic nerve. The heart was enlarged and rotated to the left, with enlargement of the RA. A purse string suture was made on the free wall of the RA and the arterial sheath was introduced. The size of the defect was measured in two dimensions using preoperatively transthoracic echocardiography (TTE) and intraoperatively epicardial echocardiography (Figure 1 B). Under guidance of transesophageal...
