Indirect arterial cannulation techniques, such as of the innominate artery (IA) using an end-to-side anastomosed vascular graft, are commonly used to establish cardiopulmonary bypass in congenital cardiac surgery. Although rare, unintended consequences, graft infection, may occur. We describe a case IA infection with subsequent pseudoaneurysm formation 10-year-old child who underwent multiple procedures for Tetralogy Fallot absent pulmonary valve syndrome.
Background Extracorporeal membrane oxygenation (ECMO) is a life-saving measure for pediatric patients with cardiopulmonary failure. The option of cannulating neck vessels versus those the groin exists over 15 kg; however, each carries risk complications. We present single-center experience comparing risks and benefits these alternate peripheral ECMO cannulation sites. Methods All supported by venoarterial (VA) via from January 2006 to May 2013 were retrospectively reviewed, excluding...
Stent infection following percutaneous transluminal coronary angioplasty is rare. We present such a case involving drug-eluting stent placed in the left anterior descending artery that was managed surgically with removal of concomitant bypass grafting. Early surgical intervention directed at infected stent, debridement and distal vessel revascularisation recommended to deal prevent myocardial compromise.
Objective: This study examines the efficacy of a comprehensive, multidisciplinary wound management team and negative pressure therapy (NPWT) for treatment sternal infections in congenital heart surgery patients. Method: A single-institution retrospective review all patients with post-operative who were treated NPWT was performed. Patients evaluated based on (a) whether occurred before or after establishment team, (b) initiated early (within 2 days) late (greater than diagnosis infection....
Background: Congenital ion channel disorders, including congenital long QT syndrome (LQTS), cause significant morbidity in pediatric patients. When medication therapy does not control symptoms or arrhythmias, more invasive treatment strategies may be necessary. This study examines our institution’s clinical experience with surgical cardiac denervation for management of these arrhythmogenic disorders children. Methods: An institutional review board–approved retrospective identified ten...
Following congenital heart surgery, pediatric patients may experience persistent respiratory failure that requires tracheostomy placement. Currently, definitive knowledge of the optimal timing for placement in this patient population is lacking.An 8-year retrospective review 17 who underwent surgery and subsequently required was performed. Patients were evaluated with regard to mortality.The overall study mortality 24%. The median duration intubation prior 60 days (interquartile range: 19-90...
Right ventricular outflow tract (RVOT) aneurysm is a known complication of tetralogy Fallot repair when ventriculotomy done. It leads to RV dysfunction and may require re-operation. We describe rare instance patient who developed an RVOT after trans-ventricular Fallot, which was complicated with the formation thrombus in sac. The underwent re-operation thrombectomy, excision pulmonary valve replacement. To best our knowledge, occurrence this combination its implications have not been reported.
Background: Mechanical circulatory support (MCS) of a failing Fontan circulation remains challenging. We hypothesized that MCS can be provided by converting the into mechanically assisted single ventricle parallel (MASVC). Methods: A porcine model functionally univentricular was created under cardiopulmonary bypass (CPB) performing an atrial septectomy, tricuspid valvectomy, and interrupting antegrade pulmonary blood flow. centrifugal flow pump placed with inflow from common atrium. Eight...
Background: Although there are considerable data regarding in-hospital results of congenital heart surgery (CHS) patients requiring postoperative extracorporeal membrane oxygenation (ECMO) support, is limited information on intermediate-term outcomes. Methods: A single-institution retrospective review 25 consecutive CHS who required ECMO and survived to hospital discharge between January 2003 June 2008. Survival was estimated by the Kaplan-Meier method. Results: At a median follow-up 3.3...
We hypothesize that mechanical assistance of the pulmonary blood flow in a Norwood circulation can increase systemic and oxygen delivery. The aim study was to compare haemodynamics an unassisted Blalock-Taussig shunt with mechanically assisted flow-based circulation, using lumped parameter computational model.A neonatal circulatory model developed simulate 3.5-mm 3.5-kg neonate. A roller pump assist device inflow bladder incorporated into support circulation. Computer simulations were used...
Tricuspid atresia and aortopulmonary window are rare congenital cardiac anomalies. The occurrence of both these anomalies in the same patient is extremely rare, with only 1 case reported literature. We report surgical management one such discuss issues respect to Stage single ventricle palliation.
Abstract: Pulmonary artery (PA) stenosis due to Takayasu Arteritis (TA) is usually managed by angioplasty techniques. We present a patient with isolated PA TA in-stent stenosis. The surgical management and pathophysiology of this disease are reviewed. (J Card Surg 2012;27:365-367)
The use of extracorporeal membrane oxygenation (ECMO) in terminally ill pediatric patients who are not candidates for long-term mechanical circulatory support or heart transplantation requires careful deliberation. We present the case a 16-year-old female with relapse acute lymphoid leukemia and acute-on-chronic cardiomyopathy received short-term ECMO therapy. In addition, we highlight several ethical considerations that were crucial to this patient’s family-centered care demonstrate therapy...
