Adrian J Tarca, Luke Eckersley, Darshan Kothari
This brief report describes a case of flail anterior tricuspid valve leaflet in a neonate associated with maternal antiphospholipid syndrome. Fetal echocardiography at 27 weeks of gestation showed competent atrioventricular valves with biventricular echogenic chordae. Fetal distress was noted at delivery, and echocardiography showed a flail anterior leaflet of the tricuspid valve with severe regurgitation. Possible causation and implications of maternal antiphospholipid syndrome are discussed.

BACKGROUND: Mechanical circulatory support is a common practice nowadays in the management of patients after cardiogenic shock due to myocardial infarction. The single or combined use of one or more devices for mechanical support depends not only on the advantage or disadvantage of these devices but also on the timing of use of these devices before the development of multi organ failure. In our case we used more than one tool for mechanical circulatory support during the prolonged and complicated course of our patient with postcardiotomy cardiogenic shock after coronary artery bypass surgery...

OBJECTIVE: Patients with a borderline left ventricular hypoplasia in the hypoplastic left heart syndrome variant or an unbalanced atrioventricular canal who undergo initial single-ventricle palliation may be candidates for biventricular (BiV) conversion following left ventricle (LV) recruitment procedures. We investigated associations among preoperative parameters and postoperative outcomes in patients undergoing BiV conversion. METHODS: We performed a retrospective review of patients who underwent BiV conversion to determine variables associated with clinical outcomes...

OBJECTIVES: Management strategy for unbalanced complete atrioventricular septal defects (CASVSDs) includes single-ventricle (SV) palliation and primary or staged biventricular (BiV) repair. More recently, BiV conversion (BiVC) from SV palliation and staged BiV recruitment (BiVR) have also been advocated. This study assesses mid-term outcomes in patients with unbalanced CASVSDs according to management strategy. METHODS: Consecutive patients with unbalanced CASVSDs who underwent surgery at a tertiary care centre from January 2000 to February 2016 with institutional review board approval...

OBJECTIVES: Open heart surgery for interrupted aortic arch in the neonatal period is still a high-risk procedure related in part to patient factors such as low birth weight, other morphologic anomalies, and, especially, small aortic valve size. Recently, we performed hybrid palliation with bilateral pulmonary artery banding and ductal stenting as the first-stage palliation for such cases. In this study, the outcomes of this procedure were examined. METHODS: Six cases of interrupted aortic arch with a small aortic valve underwent the hybrid procedure in the neonatal period in our institute from 2010 to 2015 (mean age: 6...

OBJECTIVES: In the surgical treatment of pulmonary atresia with intact ventricular septum, the size of the tricuspid valve annulus (as measured by z-scores) has emerged as a significant factor in deciding which repair to perform. Various tricuspid valve annulus z-scores are reported as "cutoffs" for successful biventricular repair. We aimed to determine whether the use of different z-score data sets contributed to the gross variation in "cutoffs" for successful biventricular repair reported in the literature...

BACKGROUND: Although the majority of Class III congestive heart failure (HF) patients treated with cardiac resynchronization therapy (CRT) show a clinical benefit, up to 40% of patients do not respond to CRT. This paper reports the design of the MultiPoint Pacing (MPP) trial, a prospective, randomized, double-blind, controlled study to evaluate the safety and efficacy of CRT using MPP compared to standard biventricular (Bi-V) pacing. METHODS: A maximum of 506 patients with a standard CRT-D indication will be enrolled at up to 50 US centers...

We report an initial investigation of a subtraction-based method to estimate right ventricle ejection fraction (RVEF) from ECG-gated planar equilibrium radionuclide angiography (ERNA) data. Twenty-six consecutive patients referred for scintigraphic evaluation of cardiac function prior to chemotherapy had ECG-gated first-pass (FP) imaging and ERNA imaging performed following the same radiotracer injection. RVEF was computed from FP images (RVEFFP) and separately from ERNA images (RVEFERNA). Standard methods for computing ejection fractions were used to obtain RVEFFP values...

PURPOSE: Cardiac resynchronization therapy (CRT) has been shown to improve left atrial function; however the effect on reverse electrical remodeling has been poorly evaluated. We hypothesized that CRT might induce reverse atrial electrical remodeling manifesting in the surface ECG as a shortening in P-wave duration. METHODS: Patients with CRT and more than 92% biventricular pacing at minimum follow-up of 1 year were included in the analysis. Those with prior history of atrial fibrillation (AF) were excluded...

Right ventricular (RV) pacing can be associated with impairment of left ventricular (LV) function due to electrical dyssynchrony and myocardial remodeling (Janousek et al. in J Cardiovasc Electrophysiol 15:470-474, 2004). RV-pacing induced ventricular dysfunction is reversible by techniques such as biventricular pacing and LV apical or LV free wall pacing or turning the pacemaker off which have all been shown to restore synchrony and improve left ventricular function (Janousek et al. in J Cardiovasc Electrophysiol 15:470-474, 2004; Geldorp et al...

Right ventricular failure (RVF) is a significant issue when considering left ventricular assist device (LVAD) implantation in pediatrics. The aim of this study was to evaluate the effects of LVAD on right ventricular (RV) function in children. We retrospectively reviewed clinical and echocardiographic data of children who underwent Berlin Heart EXCOR LVAD focusing on RV function before and after implantation (1, 3, and 6 month follow-up). An isolated LVAD was used in 27 patients. Median age was 11 months (interquartile range [IQR]: 5-24 months), with a median weight of 6...

BACKGROUND: The currently proposed criteria for identifying patients who would benefit from cardiac resynchronization therapy (CRT) still need to be optimized. A multi-scale heart simulation capable of reproducing the electrophysiology and mechanics of a beating heart may help resolve this problem. The objective of this retrospective study was to test the capability of patient-specific simulation models to reproduce the response to CRT by applying the latest multi-scale heart simulation technology...

OBJECTIVE: Limited data exist regarding the outcomes of non-cardiac procedures (NCPs) in adult patients after Fontan operations (Fontan patients). METHODS: To compare procedural outcomes after NCPs in Fontan patients with outcomes for two matched control groups: patients with repaired congenital heart disease and biventricular circulation (CHD-BiV) and patients with no heart disease (NHD). We defined cyanosis as oxygen saturation <90% and procedural hypoxia as saturation <80% or a decrease in saturation >10% from baseline...

BACKGROUND AND AIM OF THE STUDY: Left ventricular (LV) distention, a recognized complication in patients supported with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for refractory cardiogenic shock, can lead to pulmonary edema, increased myocardial oxygen consumption, and LV thrombus formation. Atrial septostomy was examined as a management strategy for LV distension. METHODS: Of 72 patients supported with VA-ECMO, seven patients underwent atrial septostomy through a trans-septal approach...

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (RV) dysfunction, accounting for 20% of sudden cardiac deaths. Characterized by the fibro-fatty infiltration of the RV free wall, ARVD/C presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular failure in adults. The coronary risk in these patients is not clear. We present an incidental finding: the left anterior descending artery cut-off in a middle-aged man with ARVD/C...

The development of technology and limitation of numerous ventricular assist devices has increased usage of the total artificial heart (TAH) for mechanical circulatory support. A primary important feature of TAH is that it is one of the few mechanical circulatory support devices that provides biventricular support. As the number of patients with TAH rises, spreading awareness about the device in the interventional radiology community is important.

OBJECTIVE: To evaluate left univentricular (LUV) pacing for cardiac resynchronization therapy (CRT) using a rate-adaptive atrioventricular delay (RAAVD) algorithm to track physiological atrioventricular delay (AVD). METHODS: A total of 72 patients with congestive heart failure (CHF) were randomized to RAAVD LUV pacing versus standard biventricular (BiV) pacing in a 1: 1 ratio. Echocardiography was used to optimize AVD for both groups. The effects of sequential BiV pacing and LUV pacing with optimized A-V (right atrio-LV) delay using an RAAVD algorithm were compared...
