RESUMO

We implanted two sinus Superflex DS© stents in a systemic non-stenotic arterial duct of a newborn with hypoplastic left heart syndrome. Forty-eight hours later an important collapse of the stent was detected and treated with a balloon expandable stent. Sinus Superflex DS© has been specifically designed for systemic ducts. This complication generates doubts about its radial force in this scenario.

RESUMO

We report an asymptomatic 5-year-old boy with coronary artery fistulas to pulmonary parenchyma and to systemic thoracic arteries, like a "natural bypass", detected during a coronary angiography performed 11 months after his heart transplant. One year later, a new coronary angiography showed no fistula. Some changes to immunosuppressive therapy during this time could be related to this evolution.

RESUMO

"Persistence of the fifth aortic arch" is a rare congenital abnormal vessel arising from the distal ascending aorta connecting with the systemic or pulmonary circulation. We report a case of a type A interruption of the aortic arch and a coarctation of the fifth aortic arch, which connected the ascending with the descending aorta. No cardiac surgery was required because a covered stent was successfully implanted in the fifth aortic arch when the patient was 4 years old. A chromosome 9 q arm duplication of uncertain significance was also found, an anomaly never described before in this clinical context.

RESUMO

A newborn was referred to our department, due to the presence of a cardiac murmur. Echocardiographic study showed a small membranous ventricular septal defect and a yuxta-aortic mass. In the follow-up, patient remained asymptomatic, ventricular septal defect closed, and yuxta-aortic mass increase in size with somatic growth. A transesophageal echocardiography was carried out, showing a fibrotic and dyskinetic left ventricular subaortic aneurysm of 19×18 mm. Given that the patient remained asymptomatic, a conservative approach was adopted. Congenital left ventricular subaortic aneurysm is an infrequent entity, and rupture, endocarditis, coronary compression, thromboembolism, arrhythmias and aortic insufficiency are some of its complications, but, as in our patient, if aneurysm is not associated with complications, patient is asymptomatic, and aneurysm growth is not very important, a conservative approach can be adopted, with a close surveillance.

RESUMO

A 29-week-old male foetus was diagnosed by foetal echocardiography with severe hypertrophic cardiomyopathy with systolic dysfunction and generalized oedema, undergoing a Caesarean section at 33 weeks. Mechanical ventilation and milrinone infusion were required during the first week. Systolic function and output parameters improved progressively. Metabolic and infectious screenings were negative. At the follow-up, during the first year of life, hypertrophy regressed, posterior right auricular hypertrophy evolved to a mass with cysts, and left ventricular myocardium developed trabeculations accomplishing non-compaction criteria. Recently, mutations in genes previously implicated in the pathogenesis of hypertrophic cardiomyopathy have been identified in patients with left ventricular non-compaction without hypertrophy. This report suggests that these cardiomyopathies may have a similar genetic origin, and can co-exist in the same patient.

RESUMO

Constrictive pericarditis has been defined classically as a progressive condition, characterized by pericardial fibrosis, with or without calcification, which results in chronic refractory congestive heart failure and for witch pericardiectomy is often required. In the last decades there have been reports describing a transient form of constrictive pericarditis, which resolves without surgical therapy. This "fibroelastic form" would represent the acute or subacute phase of constriction. In many patients, pericardial inflammation continues and pericardial fibrosis and calcification develop, leading to a chronic and rigid constrictive pericarditis. However, in some patients, pericardial inflammation resolves without progressing to chronic constrictive pericarditis. We report a 7 year old boy, who developed clinical and echocardiographical findings of pericardial constriction 5 weeks after a cardiac surgery, which resolved with steroid therapy.

RESUMO

An asymptomatic 1-month-old girl was studied in another institution because of the presence of a cardiac murmur, and referred to our center for further evaluation as a result of tricuspid valve abnormalities detected in the echocardiographic study. Echocardiography revealed a very redundant, thin, freely mobile structure in the right atrium, moving rapidly in (systole) and out (diastole) of the right ventricle through the tricuspid orifice. It arose from near the border of the inferior vena cava and attached to the atrial wall close to the coronary sinus ostium, suggesting an unusually prominent Chiari's network. Three-dimensional imaging allowed definition of the structure in all the planes and dimensions, and the relationship of the structure with right atrium and ventricle. Chiari's network is an embryonic remnant present in 2% to 3% of the population. The identification of a Chiari's network is important because the widely mobile structure within the right atrium can be confused with other entities, such as right heart vegetation, flail tricuspid leaflet, ruptured chordae tendinae, or a thrombus.

RESUMO

Congenital ventricular aneurysm (CVA) is a rare, poorly understood and potentially lethal cardiac anomaly. We report a neonatal case, remitted to our hospital due to a cardiogenic shock. Echocardiographic study revealed a severe aortic stenosis and a giant left ventricular aneurysm. Surgical intervention was carried out with extracorporeal circulation support, but without cardiac arrest, achieving aortic valvulotomy and aneurismal resection. The postoperative course was uneventful during the first 24 h, but on the second day, the patient presented a sudden unexpected cardiac arrest, not responding to the resuscitation manoeuvres.
