Pentalogy of Cantrell.

Abstract

Pentalogy of Cantrell (POC) consists of 5 congenital defects that include defects of the heart, pericardium, sternum, diaphragm, and the anterior abdominal wall. The reported incidence varies between 1:65,000 and 1:200,000 births,1Cantrell J.R. Haller J.A. Ravitch M.M.

Patients with pentalogy of Cantrell usually have ectopia cordis, a condition where the heart protrudes to the ventral abdominal wall, and it is covered by an omphalocele-type membrane. Multiple cardiac anomalies can be found in these patients, the most common being ventricular septal defects and tetralogy of Fallot.2Alphonso N. Venugopal P.S. Deshpande R. Anderson D.

At the 32 weeks of gestation, an epigastric hernia with ectopia cordis covered by pericardium was observed. Postnatal echocardiography was performed, showing the absence of sternum, a common atrium, single, double outlet, morphologic right ventricle with complete atrioventricular septal defect with a common atrioventricular valve and pulmonic stenosis (maximum gradient of 61 mm Hg) and posterior aorta (Fig. 1A-C). Cardiac magnetic resonance imaging was performed, confirming the echocardiographic findings of bronchial and abdominal situs solitus (Fig. 2A-E).Figure 2(A) Cardiac magnetic resonance. T1-sequence MRI in sagittal view showed tortuosity in the aorta (yellow arrow), ectopia cordis and severe kyphosis of the thoracic column (blue arrow). (B) T2-weighted sequences presenting atrial situs solitus (right and left atrial appendages marked with an asterisk and white arrow) with a common atrioventricular valve and single ventricle, central liver, and loss of the continuity of the anterior thoracic wall due to the absence of the sternum. (C) Three-dimensional (3D) volumetric reconstruction showed a thoracic mass corresponding to the ectopic heart. (D) 3D navigator in axial view evidenced the main pulmonary artery and its branches. (E) 3D navigator in sagittal view confirmed the tortuosity in the aorta and showed the outlet of the main pulmonary artery, both arising from the single ventricle.CV, common ventricle; LPA, left pulmonary artery; PA, pulmonary artery; RPV, right pulmonary artery.View Large Image Figure ViewerDownload Hi-res image Download (PPT)Because treatment involves an extensive surgical approach, different image modalities are necessary in the preoperative evaluation.
