Acquired infundibular pulmonary stenosis associated with a congenital membranous ventricular septal defect (Gasul phenomenon) in a dog and discussion regarding causes of infundibular stenosis.

An aclinical Havanese dog was diagnosed with a membranous restrictive ventricular septal defect. The patient was represented later in their natural history due to the development of syncope. At that time the patient was diagnosed with acquired pulmonary infundibular stenosis. Balloon dilation of the stenosis was performed successfully twice over the patient's lifetime. The patient died suddenly approximately 14 months after the second balloon dilation. A discussion regarding primary infundibular pulmonary stenosis versus causes of acquired infundibular pulmonary stenosis including anomalous muscle bundles (double chamber right ventricle), tetralogy of Fallot, and infundibular stenosis is presented.

Giant right atrium and subvalvular pulmonary stenosis: A case report of an interesting combination.

A 20-year-old Congolese woman presented with presyncope, dyspnea, and anasarca. Past medical history was unremarkable. Echocardiography revealed a rare combination of giant right atrium (RA), a dilated and hypertrophied right ventricle, subvalvular pulmonary stenosis (subPS), severe tricuspid regurgitation (TR), pericardial effusion and what appeared to be a spontaneously closed ventricular septal defect (VSD). Cardiac Magnetic Resonance and Cardiac Computed Tomography confirmed the findings excluding the presence of intra-cardiac and extra-cardiac shunt and other associated congenital anomalies. The patient underwent subPS resection, right atrioplasty, and tricuspid annuloplasty. Multimodality approach facilitated the detection of the abnormalities and provided clarity when determining the optimal surgical strategy.

Double-orifice mitral valve repair.

We present the case of a 6-year-old patient with double-orifice mitral valve and severe regurgitation, which was successfully repaired. We demonstrate that mitral valve repair may be attempted even in complex anatomy such as the double-orifice mitral valve, where it can offer excellent results.

Severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in an asymptomatic woman with congenitally corrected transposition of great arteries and mesocardia: A rare case report.

Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract.

Infundibular pulmonary stenosis after radiotherapy for breast cancer.

Postoperative radiotherapy for breast cancer may be associated with cardiotoxicity. We present a case of acquired infundibular pulmonary stenosis that developed 43 years after radiotherapy for left breast cancer, which necessitated a right ventricular outflow tract myectomy.

Glomerulopathy in patients with distal duplication of chromosome 6p.

BACKGROUND: Duplication of the distal part of chromosome 6p is a rare genetic syndrome. Renal involvement has been reported in the majority of patients, including a wide range of congenital abnormalities of kidney and urinary tract and, occasionally, a proteinuric glomerulopathy. CASE PRESENTATION: Here, we report a 13-year-old girl with 6p25.3p22.1 duplication who presented with proteinuria in infancy, was later diagnosed as focal segmental glomerulosclerosis, progressed to end-stage renal disease and was successfully transplanted. CONCLUSION: A systematic literature review suggests that 15-20 % of individuals with distal 6p duplication develop progressive proteinuric glomerulopathy. Monitoring of kidney function should be recommended in all cases.

A classical case of the Gasul phenomenon.

This case demonstrates the development of secondary infundibular stenosis in a 10-year-old male child with documented large non-restrictive perimembranous ventricular septal defect in infancy - the classical Gasul phenomenon.

Muerte súbita en paciente con síndrome LEOPARD / Sudden death in a patient with LEOPARD syndrome

El síndrome LEOPARD o de Moynahan, también llamado lentiginosis múltiple, es una rara enfermedad de origen genético que origina múltiples anomalías viscerales, que incluye al corazón, y puede ser causa de muerte súbita. Se presenta el caso de una mujer de 26 años de edad, con antecedentes de miocardiopatía hipertrófica diagnosticada desde la infancia temprana que es remitida por pérdida de la conciencia relacionada con esfuerzos físicos moderados y muerte súbita recuperada. El estudio demostró la presencia de un síndrome LEOPARD con estenosis pulmonar subvalvular y miocardiopatía hipertrófica del ventrículo izquierdo como causa de la muerte súbita de origen cardíaco(AU)

20 years of arterial switch operation for simple TGA.

BACKGROUND: Arterial switch operation became the golden treatment for simple transposition of the great arteries (sTGA). We describe our experience with the arterial switch operation regarding long-term outcome and the need for re-intervention. Nevertheless, supravalvular pulmonary stenosis (SPS) remains a concern in the long run. We assess the evolution of SPS over time and evaluate the effect of technical modifications on SPS during our experience. METHODS: We performed a retrospective study on 133 patients operated with ASO for TGA between October 1991 and November 2009. Last report method was used. We reviewed our pediatric cardiology and cardiac surgery database to examine the echocardiographic data and electrocardiograms. A mean follow-up of 9.2 years (+/- 5.83 SD) was reached. RESULTS: One (0.8%) patient deceased postoperatively due to cardiogenic shock. The overall actuarial freedom from reoperation (open and percutaneous) was 88.1%, 78.5% and 76.9% at 1, 5 and 10 years. SPS needed to be treated in 17 patients. Valve regurgitation at final investigation was maximal moderate in 5 patients for the aortic valve, 10 for pulmonary valve and 3 in tricuspid valve. CONCLUSIONS: ASO shows excellent long-term results in sTGA with a very low morbidity and mortality and is therefore the procedure of choice. Re-intervention rate is determined by SPS. Since the extensive mobilization of the pulmonary arteries and the creation of a longer neo-pulmonary root, reduction in SPS was seen with no re-interventions in the second half of the group. To obtain a final comparison with the atrial switch operation, a longer Follow-up is necessary.

Tetralogía de Fallot en el paciente adulto: a propósito de un caso / Fallots tetralogy in an adult patient: Apropos of a case

La tetralogía de Fallot constituye el 10 % de todas las cardiopatías congénitas. Representa la cardiopatía congénita cianógena más frecuente en el adulto, con una incidencia de 5,8 por ciento al nacer, pero solo el 6 por ciento de los pacientes no operados viven a los 30 años de edad y el 3 por ciento a los 40 años. Después de realizada una historia clínica completa de la paciente y los exámenes complementarios necesarios, se procede a revisar la literatura y se comparan los hallazgos y en especial la evolución con lo descrito por otros autores. Se presenta a la paciente MDCC de 48 años de edad con historia clínica No 18605 que ingresa el 21/2/2013 por falta de aire intensa de 4 días de evolución, que tendía a incrementarse al realizar esfuerzo físico o al caminar largas distancia, que no se aliviaba al cambio de posición. Describe, además, que ese mismo día comenzó a notarse como si se le inflamaran haran los pies, sin coloración cianótica, ni se acompañaba de tos, expectoración, ni fiebre. Examen físico, hallazgos positivos. Aparato cardiovascular: ruidos cardiacos rítmicos de buen tono e intensidad, se ausculta soplo sistólico pulmonar III/VI, que se irradia hacia el resto del área precordial. Se le realiza la analítica de laboratorio y los exámenes de imágenes disponibles (Rx de tórax, Tomografía Axila Computarizada contrastada de tórax, ecocardiograma doppler). Se analizan fisiopatológicamente los síntomas de la pacientes y su supervivencia con tan buena calidad de vida (incluyendo dos embarazos, uno de ellos a término) sin haber sido operada y sin un seguimiento adecuado. Aunque es baja la supervivencia de los pacientes con tetralogía de Fallot después de los 40 años algunos como la paciente estudiada lo logra y con buena calidad de vida, esto no significa que no pueda presentar ciertas enfermedades, como insuficiencia cardiaca derecha o congestiva, arritmias y endocarditis(AU)

Fallot's tetralogy amounts to 10 % of all the congenital cardiopathies. It is the most frequent cyanogenic congenital cardiopathy in adults, with a 5,8 percent incidence at birth, but only 6 percent of the non-operated patient lives at the age of 30 years, and 3 percent at the age of 40. After making the clinical record of the female patient and the necessary complementary examination, we reviewed the literature and compared the findings, specially the evolution, with the facts described by other authors. We present the MDCC patient, aged 48 years with clinical record Nr 18605, entering the service on February 21st, 2013, for lack of breath of 4 days of evolution, with a tendency to increase when exercising or when walking long distances, and that do not alleviate when changing position. We also describe that the same day we began to notice feet swelling, without a cyanotic coloration or cough, expectoration or fever accompaniment. Physical examination showed positive findings. Cardiovascular tract: rhythmic cardiac noise of good tonus and intensity; we auscultated a systolic pulmonary blow III/VI, irradiating to the rest of the pre cordial area. Laboratory analysis and available imaging examination (Thoracic Rx, thoracic contrasted computerized tomography, Doppler echocardiogram) were carried out. We physio-pathologically analyzed the patient's symptoms and her survival (including two pregnancy, one of them a term pregnancy) without being operated and without an adequate follow. Although the survival of the patients with Fallot¡'s tetralogy after they are 40 years old is low, some of them, like the studied patient, achieve it and with good life quality, it does not mean that they might not present several diseases, like right or congestive cardiac insufficiency, arrhythmia and endocarditis(AU)

Isolated subpulmonic fibrous ring, mirror-image dextrocardia and situs solitus in a young lady unreported and a near miss.

Congenital diseases causing obstruction of the right ventricular outflow tract (RVOT) are common, but the isolated subpulmonary membrane/ring is extremely rare and can be difficult to diagnose precisely, especially in adults. We report a case of surgically resected isolated subpulmonic fibrous ring in a lady with mirror-image dextrocardia and abdominal situs solitus that was misdiagnosed by echocardiography as a subaortic membrane.
