RESUMO
Background: Balloon angioplasty (BA) for aortic coarctation in neonates and infants remains controversial due to high recurrence rate and vascular complications. Aim: This study aimed to determine the safety and outcome of percutaneous treatment of coarctation in neonates and infants and to share the initial experience of strategy of prepartial dilatation with high-pressure noncomplaint balloon before final targeted dilatation using low-pressure compliant balloon. Materials and Methods: Retrospective analysis of records of all neonates and infants aged <6 months who underwent BA either using only low-pressure balloon (Group A) or those with prepartial dilatation using high-pressure noncomplaint balloon followed by low-pressure compliant balloon (Group B) between July 2017 and February 2020 was performed. Demographic, clinical, echocardiographic, interventional, and follow-up data were collected for all. Results: A total of 51 patients (41.2% neonates) were included in the study. Median age was 1 month 14 days (60.8% girls) and mean weight was 3.6 ± 1.5 kg. The mean peak trans-coarctation gradient was 53 ± 12 (34-80) mmHg. The final pressure gradient dropped to <10 mmHg in all cases of Group B and only in 26.3% (5) patients of Group A (P < 0.001). Recoarctation rate was 25.5% (13) overall and was significantly higher in Group A patients (P < 0.001), in those with borderline/mildly hypoplastic arch (P = 0.04) and in those with postprocedure gradient between 10 and 20 mmHg (P = 0.02). Median time to re-coarctation was significantly delayed in Group B (P < 0.001). There were no major complications or mortality in either group. Conclusions: BA in neonates and young infants has an excellent short and mid-term safety and efficacy. The recoarctation rate is significantly reduced as well as delayed with prepartial dilatation using high-pressure noncompliant balloon.
RESUMO
Atrial myxomas are rare primary cardiac tumours with neurological manifestations being reported in 30% of cases. Though a rare cause of ischemic stroke in young patients, considering it as a possibility in absence of any obvious risk factors can help avoid misdiagnosis at early stages. We present a case of left atrial myxoma in a 36-year-old male with no known co-morbidities, showing an unusual clinical presentation of isolated bilateral painless vision loss. With multiple infarcts on Non Contrast Computerised Tomography (NCCT) and a suspicion of Atrial Myxoma on Transesophageal Echocardiography (TEE), patient was successfully managed surgically with confirmation of diagnosis on histopathology.

Pulmonary artery aneurysm presenting with dissection and hemopericardium is extremely rare, and we came across one such case in our center. The patient was a 22-year-old man who presented with dyspnoea, tachypnoea, and pallor. On evaluation, he was found to have a leaking pulmonary artery aneurysm with dissection and hemopericardium, and a patent ductus arteriosus. He underwent pericardiocentesis followed by successful closure of the ductus, aneurysmectomy, and reconstruction of the pulmonary artery.
