BACKGROUND: Currently, off-pump coronary artery bypass (OPCAB) grafting has been the standard procedure for surgical revascularization in patients with coronary artery disease (CAD). This study aimed to examine the safety and applicability of OPCAB compared with on-pump coronary artery bypass (ONCAB) in patients with severely dilated left ventricle. METHODS: A retrospective study of giant left ventricle patients [left ventricular end diastolic diameter (LVEDD) ≥ VE mm] undergoing coronary bypass grafting from 2009 through 2015 at a single center was conducted...

Significant noncardiac and genetic abnormalities (NC and GA) are common in neonates with congenital heart defects. We sought to examine current-era effect of those abnormalities on early and late outcomes following cardiac surgery. The method from 2002-2012, 1538 neonates underwent repair (n = 860, 56%) or palliation (n = 678, 44%) of congenital heart defects. Regression models examined the effect of NC and GA on operative results, resource utilization, and late outcomes. Neonates with NC and GA (n = 312, 20%) had higher incidence of prematurity (21% vs 13%; P < 0...

BACKGROUND: Children with major and severe congenital heart disease (CHD) undergoing noncardiac surgery are at increased risk of mortality. The objective of this study was to identify the predictors for in-hospital mortality, and to develop a risk stratification score that could be used to help decision making and the development of perioperative management guidelines. METHODS: We included all children with major (eg, tetralogy of Fallot with wide open pulmonary insufficiency, hypoplastic left heart syndrome including stage 1 repair) or severe CHD (eg, children with uncorrected CHD, children with documented pulmonary hypertension, children with ventricular dysfunction requiring medications, or children listed for heart transplant) recorded in the 2012 and 2013 American College of Surgeons National Surgical Quality Improvement Program Pediatric databases in a derivation cohort, and those recorded in the 2014 database in a validation cohort...

BACKGROUND: Right ventricular (RV) function alterations are invariably present in all patients after tetralogy of Fallot (TOF) repair. Unlike the developed world where most of the patients with TOF are corrected in infancy, average age of presentation and thus surgery for these patients in the developing world may be higher. We aimed to study the correlation between RV function parameters such as tricuspid annular peak systolic excursion (TAPSE), fractional area change (FAC), and tricuspid annular peak systolic velocity (S') with early outcome variables after intracardiac repair for TOF...

BACKGROUND: Red blood cell (RBC) transfusion is common during infant cardiac surgery. A previous report of pediatric heart transplant recipients showed that increased RBC transfusion volume was independently associated with increased length of intensive care unit stay. It is unclear whether transfusion to infants as a subgroup carries similar risks. This study investigated relationships between intraoperative RBC transfusion during heart transplantation and postoperative length of stay (LOS), morbidity, and mortality in infants...

We evaluated the effects of different respiratory assist modes on cerebral blood flow (CBF) and arterial oxygenation in single-ventricle patients after bidirectional superior cavopulmonary anastomosis (BCPA). We hypothesized that preserved auto-regulation of respiration during neurally adjusted ventilatory assist (NAVA) may have potential advantages for CBF and pulmonary blood flow regulation after the BCPA procedure. We enrolled 23 patients scheduled for BCPA, who underwent pressure-controlled ventilation (PCV), pressure support ventilation (PSV), and NAVA at two assist levels for all modes in a randomized order...

BACKGROUND: Management of infants with heterotaxy syndrome and functional single ventricle is complicated due to associated cardiac and extracardiac anomalies. We report current era palliation results. METHODS: Between 2002 and 2012, 67 infants with heterotaxy syndrome underwent multistage palliation. Competing risks analyses modeled events after surgery (death vs Glenn procedure) and examined factors associated with survival. In addition, early and late outcomes following first-stage palliation surgery were compared with a matched contemporaneous control group of patients with nonheterotaxy single ventricle anomalies...

BACKGROUND: We sought to further validate the novel vasoactive-ventilation-renal (VVR) score in a prospective study of a heterogeneous cohort of children undergoing cardiac surgery that includes patients with single-ventricle anatomy and residual mixing lesions. METHODS: We prospectively performed an observational study of all children less than 18 years of age who underwent surgery for congenital heart disease at our center from November 2013 to June 2014. We calculated VVR score as follows: vasoactive-inotrope score + ventilation index + (change in serum creatinine from baseline × 10)...

OBJECTIVE: Support with extracorporeal membrane oxygenation for cardiopulmonary failure is done so with venoarterial cannulation in the majority of children with single-ventricle anatomy. However, there is a growing experience for patients with pure oxygenation/ventilation impairment supported with venovenous extracorporeal membrane oxygenation. We describe that experience. METHODS: Data were collected from the Extracorporeal Life Support Organization registry for patients with single-ventricle anatomy supported with venovenous extracorporeal membrane oxygenation from 1990 to 2012...

PURPOSE: Right ventricular dysfunction (RVD) is an important prognostic factor of 30-day mortality in patients with acute pulmonary embolism (PE). The aim of our study was to evaluate whether non-electrocardiogram (ECG)-gated cardiovascular parameters attained during computed tomography pulmonary angiography (CTPA) could predict RVD in patients suspected of PE using ECG-gated cardiac CT angiography as reference. METHODS: Consecutive patients suspected of PE were referred to a ventilation/perfusion single-photon emission tomography (V/Q-SPECT) as first-line imaging procedure...

The aim of this study was to determine the optimal timing of pulmonary artery band (PAB) placement in neonates with single ventricle physiology, unrestricted pulmonary blood flow, and no systemic outflow tract obstruction. Retrospective chart review of all patients who underwent isolated PAB for single ventricle physiology between January 2005 and December 2014 was carried out. The influence of age at the time of PAB on operative mortality, the need for reoperation to adjust the PAB, the preparedness of the pulmonary vascular bed prior to the second-stage bidirectional cavopulmonary shunt (BCPS), and the outcomes following BCPS were studied...

Large head and neck teratomas are very rare. Depending on their site of origin, they can produce varying degrees of airway compromise and can interfere with the conduct of general anesthesia. Large space-occupying lesions of the face may even interfere with the simple task of mask ventilation rendering inhaled induction of general anesthesia and maintenance of spontaneous ventilation difficult. If these neoplasms coexist with cardiac lesions necessitating corrective or palliative procedures, the task of oxygenation, ventilation, and securing a definitive airway becomes challenging especially in the presence of underlying unstable hemodynamics...

A 25-year-old girl was found a large tracheoesophageal fistula (TEF) 20 cm away from the incisors by gastroscope. It was a consequence of prolong intubation after the head operation because of right temporal lobe cerebral hemorrhage broken into ventricles. The patient was tracheotomy and retained spontaneous breathing. Operation was planned to via cervical and thoracic abdominal esophageal transection plus cervical esophagogastrostomy to repair the fistula under single lung ventilation under general anesthesia...
