Transcatheter Ventricular Septal Defect Closure with Lifetech ™ Konar-MF Occluder in Infants Under 10 kg with Only Using Venous Access
AbstractTranscatheter closure of VSD remains a complex procedure in infants with technical challenges and carries the risk of significant complications, due to its complex anatomical morphology and closed proximity to the atrioventricular valves and the conduction system. In this article, we presented transcatheter VSD closure in infants under 10 kg using the Lifetech Konar-MF device via only venous route without TEE guidance and arterial access. Between January 2021 and May 2023, a total of 34 patients weighing less than 10 kg who underwent transcatheter VSD closure antegradely with Lifetech™ Konar-Multifunctional (M...

Efficacy of High-Density Three-Dimensional Mapping for Verapamil-Sensitive Left Posterior Fascicular Ventricular Tachycardia in Pediatric Patients
This study included four patients who had undergone electrophysiological study (EPS) and pediatric patients with verapamil-sensitive LPF-VT who had undergone RFA using high-density three-dimensional (3D) mapping. The included patients were 11 –14 years old. During EPS, right bundle branch block and superior configuration VT were induced in all patients. VT mapping was performed via the transseptal approach. P1 and P2 during VT were recorded in three of the four patients. All patients initially underwent RFA via the transseptal approac h. In three patients, P1 during VT was targeted, and VT was terminated. The lesion siz...

Clinical Prognosis of Vocal Cord Paralysis After Cardiothoracic Surgery in Infants
In conclusion, symptoms of postoperative VCP improved in most cases; however, paralysis persisted in half of the patients. As a screening method, LUS is useful for evaluating postoperative VCP. A more accurate understanding of VCP is needed to improve postoperative outcomes. (Source: Pediatric Cardiology)

Longitudinal Strain vs. Conventional Echocardiographic Parameters in the First Week of Life in Healthy Term Newborns
In conclusion, the results of our study show how different echocardiographic techniques capture hemodynamic changes and changes in myocardial contractility and compliance. Both longitudinal strain and tissue Doppler imaging parameters seem to offer greater sensitivity in comparison with conventional echocardiographic parameters. (Source: Pediatric Cardiology)

Impact of Atrial Pacing in Fontan Patients with Junctional Rhythm: A Prospective Echocardiographic Study
AbstractSinus node dysfunction (SND) with junctional rhythm (JR) is common after the Fontan operation. Atrial pacing (AP) restores atrioventricular (AV) synchrony, but the placement of a pacemaker carries significant morbidity. To study the impact of AP on echocardiographic parameters of function in Fontan patients with SND and JR. Nine Fontan patients with AP for SND and JR were prospectively studied with echocardiography in the following conditions —baseline paced rhythm, underlying JR and, if possible, slow-paced rhythm below their baseline paced rate (~ 10 bpm faster than their JR rate). Cardiac index was signific...

Valved Conduits for Right Ventricular Outflow Tract Reconstruction: A Review of Current Technologies and Future Directions
AbstractThe need for right ventricular outflow tract reconstruction is common and growing in congenital heart surgery given expanding indications for the repair of congenital as well as acquired heart disease. Various valved conduit options currently exist including homografts, xenograft pulmonary valved conduits (Contegra ™), and porcine valved conduits. The major limitation for all conduits is implant durability, which requires reoperation. Currently, cryopreserved homografts are often used given their superiority shown in long-term data. Significant limitations remain in the cost and availability of the graft, pa rtic...

QRS Duration After Pulmonary Valve Replacement in Adults with Repaired Tetralogy of Fallot: Association with Ventricular Arrhythmia and Correlation with Right Ventricular Size
AbstractThe aim of this study is to analyze the relationship between QRS duration after pulmonary valve replacement (PVR) and ventricular arrhythmias (VA) in patients with repaired tetralogy of Fallot (ToF). ToF patients may face complications such as heart failure and VA after primary repair, often mitigated by PVR. Prior studies have shown a decrease in QRS duration and right ventricular (RV) size following PVR. It remains unclear whether a lack of QRS duration reduction identifies patients at risk of VA. We retrospectively identified adult patients with repaired ToF who underwent surgical or transcatheter PVR. EKG data ...
