Successful Surgical Outcome of Coarctation of Aorta in an adult male

Coarctation of the aorta is a relatively common defect that accounts for 5-8% of all congenital heart defects. Coarctation of the aorta may occur as an isolated defect or in association with various other lesions, most commonly patent ductus arteriosus, bicuspid aortic valve and ventricular septal defect. The diagnosis of coarctation of the aorta may be missed or delayed unless there is a high index of suspicion and the presentation may be congestive heart failure in infant or hypertension in older children and adult. A case of coarctation of the aorta associated with patent ductus arteriosus having features of headache, exertional dyspnea and uncontrolled hypertension is being presented here. PTFE patch aortoplasty and ligation with transfixation of PDA was done. Post-operative period was uneventful and patient was discharged on 7th post-operative day.

Patent Ductus

The current diagnosis of Congenital Heart Disease (CHD) in neonates relies on echocardiography. Its limited availability requires alternative screening procedures to prioritise newborns awaiting ultrasound. The routine screening for CHD is performed using a multidimensional clinical examination including (but not limited to) auscultation and pulse oximetry. While auscultation might be subjective with some heart abnormalities not always audible it increases the ability to detect heart defects. This work aims at developing an objective clinical decision support tool based on machine learning (ML) to facilitate differentiation of sounds with signatures of Patent Ductus Arteriosus (PDA)/CHDs, in clinical settings. The heart sounds are pre-processed and segmented, followed by feature extraction. The features are fed into a boosted decision tree classifier to estimate the probability of PDA or CHDs. Several mechanisms to combine information from different auscultation points, as well as consecutive sound cycles, are presented. The system is evaluated on a large clinical dataset of heart sounds from 265 term and late-preterm newborns recorded within the first six days of life. The developed system reaches an area under the curve (AUC) of 78% at detecting CHD and 77% at detecting PDA. The obtained results for PDA detection compare favourably with the level of accuracy achieved by an experienced neonatologist when assessed on the same cohort.

Patent Ductus

Ten cases are presented of children having patent ductus arteriosus with reversal of shunt. Cyanosis, often greater in the toes, was present in all. Exertional dyspnea developed early. Murmurs were of no diagnostic value, but an accentuated pulmonic second sound was uniformly present. Right ventricular preponderance was found in all cases on the electrocardiogram. Cardiac size varied on roentgenography, but there was usually prominence of the pulmonary artery segment. Six cases showed evidence of bi-directional shunts, one showed only a reversed shunt, while data were insufficient to determine this point in the remaining three. Three patients had surgery, one with a successful outcome. The latter was a 1-year-old infant in whom lung biopsy at surgery revealed only minimal pulmonary arterial changes. Forty-five cases are reviewed from the literature. The majority of these occurred in adults. Twenty-two have been subjected to surgery, four with good results, three of the latter being children. The differential diagnosis is briefly discussed. The safest and simplest diagnostic test to perform is the determination of oxygen saturation of samples of blood obtained simultaneously from the right brachial and femoral arteries. Angiocardiography and cardiac catheterization also provided helpful information. The diagnosis will not be made unless the examiner keeps the entity in mind. The entity can no longer be considered rare. Surgical treatment of the condition has been very disappointing, especially in the adult. There is reason to believe that surgical intervention very early in life will yield a higher salvage rate.
