Abstract Background Surgery for congenital heart disease has progressed by leaps and bounds in the last few decades, but the right ventricular outflow tract continues to pose a challenge to the congenital heart surgeon. Objective To describe short and intermediate term outcome in congenital heart disease patients undergoing surgical repair using right ventricle to pulmonary artery conduits. Patients and Methods Our study included 33 patients that were operated upon by putting a conduit between the right ventricle and the pulmonary artery in a single center (Al Agouza police hospital) between 2015 and 2019. Results This study was done in order to follow up patients who underwent surgery for conduit placement between the right ventricle (RV) and the pulmonary artery (PA), to observe the reintervention rates and to determine the most important determinants of re-operation. 33 patients were included in this study, with age range 1.5-17 years and mean age of 8.29 +/- 4.7 years. The mean age at placement of the first conduit was 3.57 +/- 3.18 years. The youngest patient at time of conduit placement for the first time was 0.2 years old and the oldest had 12.5 years. Conclusion The use of conduits to treat the RV to PA discontinuity is a cornerstone in the treatment of some congenital heart diseases requiring construction of the right ventricle outflow tract (RVOT). Nevertheless, conduit failure and replacement is inevitable, and depends on many factors: as age at first operation, type of conduit, mean and peak pressure gradient across the conduit. The higher the age at first conduit, the bigger the event / re-intervention free survival period.

Patent Ductus

Introduction: PDA represents one of the most frequently diagnosed type of congenital heart disease. Ductus arteriosus is a normal structure in foetal life, which permits shunting of oxygenated blood from the pulmonary artery into the aorta. Failure of sealing after birth is an abnormal condition and is called patent ductus arteriosus. In normal PDA, due to fact that systemic pressure is fivefold higher than pulmonary circulation, blood is shunted from the aorta into the pulmonary artery. In reverse PDA, pulmonary artery pressure does not drop after birth, and blood will be shunted form right to left. Aims: We want to evaluate clinical, haematological, ECG and echocardiographic changes in case of reverse PDA. Materials and Methods: Two-year old female Bichon Frise was referred to our clinic with signs of effort intolerance and dyspnoea for more than a year. ECG was performed in the right lateral recumbency using a digital device and echocardiography was done with Esaote MyLab40 Vet with a phased array transducer matched with the size of the dog (7.5 MHz). Results: We identified a dog with a good body score, quite alert and without any sign of illness. Haematological investigation underlined polycythaemia and very high PCV. The ECG revealed a normal sinus rhythm with a deep S wave, changes consistent with right ventricle enlargement.  Right atrial dilation and right ventricle hypertrophy were found on cardiac ultrasonography. The right ventricle free wall was hypertrophied and interventricular septum was flattened, changes consistent with increased pressure on the right side of the heart. The left heart was small. Positive diagnosis was done, performing “bubble study” and identification of contrast bubble within the abdominal aorta.   Conclusion: Reverse PDA is a rarely diagnosed congenital heart disease. Polycythaemia in young dogs could raise the suspicion of reverse PDA.  For positive diagnosis, echocardiography and bubble study are required. ECG is not a sensitive tool for diagnosis.

Congenital heart diseases that cause obstruction of the right ventricular outflow tract are often difficult to diagnose. We report the case of a 49-year-old man who presented with long-standing shortness of breath on exertion. Imaging revealed right ventricular outflow tract obstruction caused by a double-chambered right ventricle, and he was referred for surgical correction. This case emphasizes both the detailed perioperative evaluation that is needed when diagnosing adults who present with manifestations of congenital heart disease and a method of successful surgical correction that resulted in symptom resolution.
