OBJECTIVES: To determine the early, intermediate and long-term outcomes of pulmonary atresia with ventricular septal defect (PA/VSD) Types I, II and III initially palliated by a right ventricle to pulmonary artery (RVPA) connection. METHODS: We performed a retrospective study from 2000 to 2014 that included 109 patients with PA/VSD who had undergone an RVPA connection (tetralogy of Fallot and PA/VSD Type IV excluded). The end-points of this strategy were adequate pulmonary artery tree post-palliation, second palliation, biventricular repair, right ventricular pressure post-biventricular repair and late reoperation...

Ebstein's anomaly in combination with tetralogy of Fallot (TOF) is rare. We report a male infant with these combined anomalies who presented with severe cyanosis, heart failure, and respiratory distress after birth. Biventricular repair was successfully performed with 1-stage correction of his ventricular septal defect (VSD), right ventricular outflow tract (RVOT) obstruction, and tricuspid regurgitation. The downward displaced tricuspid valve was also restored to the normal annulus position. The infant recovered well...

Through a series of complex surgical and interventional procedures including downsizing of an unrestricted atrial septal defect, aortic arch reconstruction, pulmonary artery banding, reversed Potts shunt, and Melody valve in a mitral position, biventricular conversion was successfully achieved in a patient with a distinct borderline left ventricle. By use of these interventional steps, flow-mediated and load-mediated growth of a small left ventricle was observed, highlighting the plasticity of hearts in growing children...

The increasing number of patients with adult congenital heart disease (ACHD) calls for the development of noninvasive imaging techniques that allow a long-term evaluation of native and postsurgical anatomy and function. Echocardiography remains the imaging modality of choice for congenital heart disease, but it is affected by limited acoustic windows and poor tissue characterization. Cardiac computed tomography and cardiac catheter angiography are 2 valid alternatives for the anatomic and functional assessment of ACHD; however, both use ionizing radiation, and cardiac catheter angiography requires an invasive approach...

INTRODUCTION: Right ventricular (RV) systolic dysfunction is common in acute respiratory distress syndrome (ARDS). While preload optimization is crucial in its management, dynamic fluid responsiveness indices lack reliability, and there is no consensus on target central venous pressure (CVP). We analyzed the utility of RV free wall longitudinal strain (RVFWS) in the estimation of optimal RV filling pressure in ARDS. METHODS: A retrospective cross-sectional analysis of clinical data and echocardiograms of patients with ARDS was performed...

BACKGROUND: Although right ventricular pacing can contribute to cardiomyopathy, the impact of complete atrioventricular block (cAVB) on heart failure (HF) development in pacemaker patients has not been well characterized. We evaluated the incidence and time course for developing HF after pacemaker implantation for cAVB. METHODS AND RESULTS: A MarketScan database identified patients undergoing dual-chamber pacemaker implantation from 2008 to 2014. Patients with cAVB were identified by an atrioventricular node ablation or diagnosis of third-degree AVB...

BACKGROUND: In biventricular hearts the filling and contractility of one ventricle affects the performance of the other. In this study, we compared right ventricular systolic function and exercise capacity in patients with a subaortic right ventricle (RV) in relation to the presence of a left ventricular outflow tract obstruction (LVOTO). METHODS: Retrospective chart review of adults with congenitally corrected transposition of the great arteries (ccTGA) or with a previous atrial switch procedure for complete TGA (D-TGA)...

OBJECTIVES: Although evidence exists of broadly defined memory impairment among adolescents with critical congenital heart disease (CHD), nuanced investigations of declarative memory in this at-risk population have not been conducted. This study had two primary aims: (1) to conduct a fine-grained analysis of a range of relevant learning and memory processes in adolescents with critical biventricular CHD, and (2) to identify risk, odds, and predictors of memory impairment. METHODS: Data were combined from two single-center studies of neurodevelopmental outcomes in critical CHD...

The objective assessments of left ventricular (LV) and right ventricular (RV) ejection fractions (EFs) are the main important tasks of routine cardiovascular magnetic resonance (CMR). Over the years, CMR has emerged as the reference standard for the evaluation of biventricular morphology and function. However, changes in EF may occur in the late stages of the majority of cardiac diseases, and being a measure of global function, it has limited sensitivity for identifying regional myocardial impairment. On the other hand, current wall motion evaluation is done on a subjective basis and subjective, qualitative analysis has a substantial error rate...

BACKGROUND: Electrophysiology procedures require fluoroscopic guidance, with the associated potentially adverse effects of ionising radiation. Newer fluoroscopy systems have more features that enable dose-reduction strategies. This study aimed to investigate any reduction in radiation dose between an older fluoroscopy system (Philips Integris H5000) and one of the latest systems (Siemens Artis Q), optimised with dose-reduction strategies. METHODS: Radiation dose measures were collected over a two year period in a single electrophysiology laboratory...

BACKGROUND: Swift and adequate fluid loading is a cornerstone of septic shock therapy. Yet, careful assessment of volume responsiveness and volume amount during the resuscitation process is a prerequisite. Both overzealous initial fluid administration and late fluid overload are harmful and may be associated with increased mortality. MAIN BODY: Static (i.e., central venous or pulmonary artery occlusion) pressure readings are erroneous for monitoring fluid resuscitation and should be abandoned...

Recurrent aortic arch obstruction (RAAO) remains a major cause of morbidity following surgical neonatal repair of coarctation of the aorta (CoA). Elucidating predictors of RAAO can identify high-risk patients and guide postoperative management. The Coarctation index (CoA-I), defined as the ratio of the diameter of the narrowest aortic arch segment to the diameter of the descending aorta, has been used to help diagnose RAAO in neonates following the Norwood Procedure. We sought to assess the predictive value of the CoA-I on RAAO after CoA repair in infants with biventricular circulation...

BACKGROUND: Device reimplantation after extraction due to cardiac implantable electronic device (CIED) infection in pacemaker-dependent patients can be challenging in patients with limited access options. OBJECTIVE: We describe a straight-forward, low lateral thoracic implantation technique for patients with a patent axillary vein but unavailable bilateral pectoral sites. METHODS: We included 9 pacemaker-dependent patients (mean age 70±13, 7 male) who underwent CIED extraction and low lateral thoracic reimplant, in whom bilateral pectoral sites were unavailable...

PURPOSE: Pulmonary hypertension (PH) is characterized by abnormally increased pulmonary vascular pressure, leading to deteriorated right ventricular function and premature death. Pulmonary mean transit time (PMTT) and biventricular function response to exercise in first-pass radionuclide angiography (FP-RNA) may provide early detection and timely disease monitoring of PH. This study aimed to investigate the diagnostic and prognostic values of this imaging modality in PH patients. METHODS: Left and right ventricular ejection fraction (LVEF/RVEF) and PMTT at rest and immediately after exercise treadmill test were measured by FP-RNA in 77 consecutive patients with clinical presentations suggestive of PH (aged 46 ± 15 years, 33 men), mostly with symptoms of unexplained progressive dyspnea...

BACKGROUND: Exercise stress echocardiography (ESE) can unmask ventricular dysfunction in asymptomatic patients with congenital heart disease (CHD), but its acquisition and interpretation is often challenging, and the method has not been validated in CHD. This study aimed to evaluate the feasibility of ESE using Doppler imaging and to assess myocardial response to exercise in patients with biventricular (BiV) and univentricular (UniV) circulation after CHD repair. METHODS: In this single-center prospective study, we recruited 55 participants (17 females), median age 14 years (8-22 years)...

Endo-ventricular thrombosis represents a possible clinical complication of stress(takotsubo)-cardiomyopathy (SC). Depressed ventricular systolic ventricular function, localized left ventricular (LV) dyskinesis, but also an increased pro-thrombotic state induced by catecholamine surge may facilitate the occurrence of endovascular thrombosis in SC. SC, however, may also present as right ventricular (RV) dysfunction or even as biventricular ballooning. Ventricular thrombosis may therefore theoretically occur in either ventricles or both...
