Giant congenital diverticulum of the right atrium.

Congenital diverticulum of heart is a rare entity, which may arise from the atria, atrial appendages, coronary sinus or the ventricles. A 3-year-old child presented with history of early fatigability for 6 months and recent upper respiratory tract infection. Chest X-ray and echocardiogram revealed marked right atrial enlargement. At surgery, a right atrial diverticulum was excised under cardiopulmonary bypass. Pathology revealed thickened endocardium with edema and myocardial fiber hypertrophy. Our experience with this rare congenital disease is presented along with a review of the literature.

Comparison between transcatheter closure and minimally invasive surgery for fossa ovalis atrial septal defect: a single institutional experience.

BACKGROUND: Although, conventional surgical closure of atrial septal defect (ASD) provides excellent results with very low mortality and morbidity, it leaves the scar of incision and postoperative pain. Newer treatment modalities like minimal invasive surgery and percutaneous closure are being increasingly used nowadays where available. AIM: To compare the patient population, success, safety, and efficacy of transcatheter closure of ASD (Group A) with that of minimally invasive surgery (Port Access) (Group B). METHODS: In this retrospective non-randomized study, a record of a total of 640 patients with diagnosis of ASD secundum between May 1997 and October 2006 were reviewed. A total of 470 out of 640 patients were selected for transcatheter closure (Group A) while 170 patients were taken for surgical closure by minimally invasive port access surgery (Group B). The safety and efficacy of two groups was evaluated on the basis of morbidity and mortality, duration of intensive care unit (ICU) stay, total duration of hospital stay, post-procedural complications, residual sequel at time of discharge, and residual flow across the ASD. RESULTS: Success rate in two groups was 97.1% and 99.4%, respectively and had no statistically significant difference. Similarly major complication rate also had no difference in statistical significance (1.8% and 2.9% for Group A and B, respectively). Group B patients had longer hospital stay. A small but significant number of patients were not found suitable for device closure. This number is likely to decrease as experience with technique increases. Port access surgery is currently not possible in small children (femoral artery diameter 35 mm) due to difficulty in cannulation. CONCLUSION: Percutaneous device closure of ASD can be offered as a treatment option in suitable patients. Port access is minimally invasive and an equally safe and effective alternative choice in ASDs with deficient rim in patient with appropriate age and weight.

Aortico-left ventricular tunnel: echocardiographic recognition.

Aortico-left ventricular tunnel (ALVT) is a rare congenital malformation characterized by an abnormal communication between aorta and left ventricular cavity and the child presents with features of congestive heart failure in early infancy. We report the case of a 7-day-old baby who was diagnosed as a case of ALVT by echocardiography. The child was operated successfully and echocardiographic findings were confirmed.
