We present the use of a low-resistance membrane oxygenator (Quadrox D, Maquet) in series with a pulsatile right ventricular assist device (Berlin Heart EXCOR, Berlin Heart) in a patient with biventricular support who required high-frequency oscillatory ventilation (HFOV), due to refractory acute respiratory distress syndrome associated with Cytomegalovirus pneumonia. The high mean airway pressure associated with the use of HFOV resulted in a significant negative impact on left ventricular assist device (LVAD) filling that led to a combined respiratory and metabolic acidosis and the need for vasopressor support...

Extracorporeal membrane oxygenation (ECMO) is an accepted treatment modality for life support refractory to conventional efforts in neonates with complex congenital heart lesions. Cannulation for ECMO can be accomplished by venovenous (VV) access where patients receive primarily respiratory support or venoarterial (VA) access which provides complete cardiopulmonary support. VV ECMO delivered by a single-vessel cannulation with a dual-chamber venous cannula allows for respiratory support while the patient remains dependent upon intrinsic cardiac function to support hemodynamics...

We report two neonates with distal ductal origin of the left pulmonary artery who also had rare vascular rings comprised of a left aortic arch and right arterial duct with a midline/rightward descending aorta. To the best of our knowledge, this association has not previously been described, although other abnormalities of the left pulmonary artery in the setting of vascular rings have been reported. We review the embryology, utility of imaging, and clinical course.

Raghib defect and double-orifice tricuspid valve are two rare congenital heart defects. We report a case of a 42-year-old man with both Raghib defect and DOTV. The patient underwent reroofing of the coronary sinus with an intra-atrial baffle and annuloplasty of the tricuspid and mitral valves via median sternotomy.

Transposition of the great arteries occurs rarely in patients with mirror image dextrocardia and situs inversus, while the combination with severe coarctation of the descending aorta (CoA) makes the anatomy even more unusual. Therefore, it is not surprising that a case with such unusual and complicated anatomy presents unique problems when a primary definitive correction is attempted. We report a patient with situs inversus totalis and complex congenital heart disease including transposition of the great arteries and severe CoA who underwent successful complete, single-stage, anatomic correction...

Accessory mitral valve tissue (AMVT) causing left ventricular outflow tract obstruction (LVOTO) is rare. We report a case of AMVT causing severe LVOTO resulting in acutely progressive symptoms of near-collapse. Urgent surgical resection eliminated the patient's life-threatening symptoms. AMVT should be considered among potential LVOTO diagnoses, and early surgical intervention may be required.

Patcharapong Suntharos, Lourdes R Prieto
Percutaneous pulmonary valve implantation is now an acceptable treatment option. The Edwards SAPIEN valve, intended for transcatheter aortic valve implantation, has been used in patients whose landing zone diameter is >22 to 24 mm which is not suitable for Melody valve. We report a patient in whom we successfully placed the latest generation, Edwards SAPIEN 3 (ES3) in the pulmonary position. However, because of the short covered portion of this valve, there was a significant paravalvular leak through the stent struts requiring implantation of a second ES3 valve...

OBJECTIVE: To assess medium-term effects of treatment for mild to moderate recoarctation in an adult population. DESIGN: We identified all patients who had coarctation repair between 1965 and 1985 in our institution. They were all (n = 156) invited to a thorough outpatient examination, which was accepted by 133. Eleven (median age 36 [28-53] years) were identified with isolated mild to moderate recoarctation and received reintervention. They comprise the patient population of the current study...

We report two cases of newborns with critical pulmonary stenosis having intact ventricular septum, who underwent pulmonary valve balloon valvuloplasty followed by banding of a patent ductus arteriosus. Transcatheter pulmonary valvuloplasty was performed one week after delivery. Following the procedure, both developed "circular shunting" as a consequence of left-to-right ductal flow and pulmonary regurgitation. This in turn caused increased blood flow into a dysfunctional right ventricle and low systemic cardiac output syndrome...

We report the case of a 23-year-old man who developed constrictive pericarditis within four months after pulmonary valve replacement and repair of partial anomalous pulmonary venous connection. He had previously undergone repair of tetralogy of Fallot in infancy. After an unsuccessful trial of medical management for persistent right heart failure, magnetic resonance imaging was done, which showed a thickened pericardium. He underwent a radical pericardiectomy with a good outcome. The case is presented to illustrate a less well-recognized cause of cardiac failure following congenital cardiac surgery, which may otherwise be attributed to the failure of surgery or residual complications...

An intramural coronary artery in the setting of truncus arteriosus (common arterial trunk) is an uncommon association. Following an uneventful surgical repair, a neonate developed a low cardiac output state deteriorating into cardiac arrest shortly after arrival into the intensive care unit, requiring extracorporeal membrane oxygenation support. Echocardiography and angiography showed occlusion of the left coronary artery, prompting emergency surgical reexploration. A "slit-like" orifice with an intramural left coronary artery was successfully unroofed, allowing full recovery...

A 2-month-old male with dysmorphic facies, neonatal thrombocytopenia, left congenital cataract, and long bone abnormalities became hypotensive with ST depression on induction of anesthesia for congenital cataract repair. Echocardiogram demonstrated decreased left ventricular function (ejection fraction 46%), mild mitral valve regurgitation (MR), and regional wall motion abnormalities. The left coronary artery could not be visualized. Subsequent cardiac catheterization confirmed atresia of the left main coronary artery...

A rare case of massive pulmonary embolism is presented in an oligosymptomatic teenager with predisposing factors. Computed tomography pulmonary angiography supported by three-dimensional reconstruction was diagnostic. The embolus qualified as massive by conventional anatomical guidelines, but as low risk by more recent functional criteria. Functional assessment has complemented morphologic assessment for risk stratification in adult patients. Such evidence is scarce in pediatrics. The patient underwent surgical embolectomy, followed by prophylactic anticoagulation, without further events...

The availability of extracorporeal membrane oxygenation (ECMO) is the standard of care at most high-acuity congenital heart surgery programs. Extracorporeal membrane oxygenation is also an integral part of managing children with in-hospital cardiac arrest refractory to conventional cardiopulmonary resuscitation (extracorporeal cardiopulmonary resuscitation). In this article, we aim to provide a practical guide to initiate rapid ECMO in a nonoperating room setting.

Circulatory arrest (CA) is traditionally utilized during the repair of total anomalous pulmonary venous return (TAPVR). Since 2005, we have exclusively repaired all types of TAPVR using continuous cardiopulmonary bypass. We present our technique using continuous cardiopulmonary bypass throughout the duration of the repair, by temporarily occluding the vertical vein and placing a pump sucker within the pulmonary venous confluence. This technique has been used on 29 consecutive patients and resulted in limited morbidity and absence of pulmonary vein stenosis from most recent follow-up...

Isolation of the subclavian artery is a rare aortic arch anomaly with fewer than 100 cases reported in the literature. Left subclavian artery isolation is seen in 0.8% of right aortic arches, and right subclavian artery isolation is seen four times less frequently. Other intracardiac or arch malformations are usually associated, among which tetralogy of Fallot is commonly described. We describe the presentation, preoperative imaging, surgical strategies, and outcomes of four patients with this rare condition and review the published literature...

BACKGROUND: Adults with congenital heart disease (ACHD) comprise a growing, increasingly complex population. The Boston Adult Congenital Heart Disease Biobank is a program for the collection and storage of biospecimens to provide a sustainable resource for scientific biomarker investigation in ACHD. METHODS: We describe a protocol to collect, process, and store biospecimens for ACHD or associated diagnoses developed based on existing literature and consultation with cardiovascular biomarker epidemiologists...

BACKGROUND: In recent decades, humanitarian cardiology and cardiac surgery have shifted toward sending short-term surgical and catheter missions to treat patients. Although this model has been shown to be effective in bringing cardiovascular care to the patients' environment, its effectiveness in creating sustainable service is questioned. This study reports the barriers to contribution of missions to effective skill transfer and possible improvements needed in the future, from the perspective of both the local and overseas teams...
