Article Abstract
Objective: To demonstrate a detailed procedural guide for right ventricular outflow tract (RVOT) stent placement for palliation of tetralogy of Fallot and pulmonary stenosis in a patient weighing <2 kg.
Key Steps: Obtain wire position with an 0.018-inch Hi-Torque floppy wire in a distal branch pulmonary artery. Exchange femoral venous sheath with a 5-F CHB sheath for stable stent delivery and angiograms during stent positioning. Stent RVOT with a 5 × 16 mm Formula 418 stent.
Potential Pitfalls: Coronary stents have a smaller profile and can be easier to position in the RVOT, but limit subsequent dilations to larger diameters without additional stent placement. Long sheaths can be difficult to manipulate in small infants, but allow for angiograms during stent positioning for optimal placement.
Take-home Message: Bare metal stents that are expandable to larger diameters can be safely used for RVOT stenting even in neonates <2 kg and allow for palliation until surgical repair with a single stent.

Department of Adult Cardiology, Jakaya Kikwete Cardiac Institute (JKCI), Dar es Salaam, Tanzania.
Background: Transcatheter pulmonary valve implantation (TPVI) has emerged as a viable alternative to surgical pulmonary valve replacement for patients with congenital heart disease and right ventricular outflow tract dysfunction. However, its adoption in low-resource settings has been limited.
Case Summary: We report the first successful TPVI procedures in Tanzania.

Objective This research investigated the application of real-time, three-dimensional speckle tracking imaging (RT-3D-STI) to evaluate left atrial (LA) function in individuals suffering from hypertensive heart disease (HHD) and heart failure with preserved ejection fraction (HFpEF).Material and methods This retrospective study included 100 patients with HHD and HFpEF hospitalized from August 2023to June 2024 (HFpEF group). 100 healthy individuals undergoing physical examinations comprised the control group.

Background: Mitral regurgitation (MR) may rarely worsen after transcatheter aortic valve implantation (TAVI) due to mechanical interference from the transcatheter heart valve (THV). Standard surgical approaches in these cases are often challenging due to anatomical constraints. Thus, there is a need for the development of effective alternatives to address this issue.

: This study aimed to compare the long-term outcomes of a modified réparation à l'étage ventriculaire (REV) and the Rastelli repair for ventricular septal defect (VSD) and pulmonary outflow tract obstruction without ventriculoarterial concordance. : The study included 100 consecutive patients who underwent a modified REV ( = 50) or Rastelli repair ( = 50) for transposition of the great arteries, double outlet right ventricle, or double outlet left ventricle with VSD and pulmonary outflow tract obstruction. The mean ages of the patients who underwent the modified REV and Rastelli repair were 2.

Background: Proper risk stratification tools for patients with obstructive hypertrophic cardiomyopathy (oHCM) undergoing septal myectomy are lacking. Our objective was to assess the predictive value of preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) on perioperative outcomes and late survival in patients with oHCM undergoing transaortic septal myectomy.
Methods: Between 2008 and 2021, 834 patients with preoperative NT-proBNP measurements underwent septal myectomy.
