Background and Objectives: Infective endocarditis in the pulmonary position is a rare disease. Isolated pulmonary valve endocarditis is extremely rare. The aim of our study was to assess patients who were treated surgically for pulmonary endocarditis at our institution from January 2003 to December 2017. Materials and Methods: We analyze eight cases of infectious endocarditis in pulmonary position out of 293 patients who were operated for infective endocarditis (2.7%, 8/293). Only two of these eight patients were not related to congenital heart malformation. They were followed for early and late mortality, long-term survival, postoperative morbidity and reoperations. Results: Among six patients suffering from congenital heart disease, four patients underwent corrections of pulmonary valve malformation previously, and their infected grafts were replaced by two allografts and two xenografts. The two other patients had replaced their infected pulmonary valves with allografts. Two non-congenital patients with pulmonary valve endocarditis underwent valve replacement with biological prosthesis. All patients survived the early postoperative course. The mean follow-up time was 9.1 (interquartile range (IQR), 5.3–12.6) years. The long-term follow-up included seven patients. One patient (12.5%, 1/8) died more than 4 years after the surgery due to sepsis. Pulmonary endocarditis was the rarest endocarditis treated surgically (p < 0.001). Conclusion: Surgery for infective endocarditis in the pulmonary position (IEPP) is an effective method of treatment with excellent early outcome and good late results despite a very uncommon pathology and few operations being performed. Surgery performed earlier may make the procedure less radical.
Background Pulmonary artery sling is commonly associated with tracheal stenosis and intracardiac anomalies. While surgical repair is standardized, coexistent anomalies often determine outcomes. With the paucity of risk stratification, this study aimed to review our experience and stratify risk factors for the surgical outcome of complex pulmonary artery sling repair in the presence of airway or intracardiac lesions. Methods Seventy-nine consecutive children with pulmonary artery sling were evaluated retrospectively following surgical repair. Median age at surgery was 5 months (interquartile range 3–9). Surgical approaches included pulmonary artery sling alone ( n = 10), pulmonary artery sling with tracheoplasty ( n = 41), and pulmonary artery sling with both intracardiac and tracheal surgery ( n = 28). Results There were 7 early (8.8%) deaths. Two patients after left pulmonary artery reimplantation needed revision of the anastomosis. The median intensive care and hospital stay were 11 (interquartile range 9.2–24.8) and 17.9 (interquartile range 4.3–19.8) days, and considerably longer when associated tracheal surgery ( p = 0.002). Follow-up was complete in 66/69 and 3 (3.8%) children died late: 2.7, 10.2, and 17 months after surgery. Univariate analysis showed abnormal lung and coexisting structural heart disease as risk factors. Multivariate analysis revealed total cardiopulmonary bypass time as an independent predictor of overall mortality. Conclusion Complex pulmonary artery sling repair can be performed with a good surgical outcomes even when associated with airway malformations or structural heart diseases. Lung abnormality and longer cardiopulmonary bypass time as a surrogate marker of complex surgery, are possible risk factors.
Giant congenital right atrial aneurysms are rare, with their natural history complicated by death, heart failure, arrhythmias, and thrombosis. Prenatal diagnosis of the defect is feasible and allows an early preparation of a plan for management. We present details of a patient diagnosed prenatally with a giant right atrial aneurysm, which was successfully treated surgically as soon as the patient became symptomatic.
MV repair with the Physio II ring has excellent short-term results, including subgroups with large anterior mitral valve leaflet (AMVL). Moreover, the dimensional ratios of the ring may allow it to be used for MV repair for degenerative MV disease, irrespective of anterior leaflet size.
