The first clinical experience of the successful application of electrostimulation of the atrial septum is described. Sickle-shaped electrodes were used for this purpose. Electrostimulation of the atrial septum was medically indicated in all cases. In 2 cases the electrode was fixed to the atrial septum after open-heart surgery and in 3 cases it was done because of an excessively high threshold of cardiac electrostimulation. Sickle-shaped electrodes are shown to be the most optimal for continuous electrostimulation of the atrial septum.

A 40-year-old man with a medical history of hepatitis B presented with abdominal distention and leg swelling. A computed tomography scan of the abdomen revealed cirrhosis and a large mass extending from the liver into the inferior vena cava and extending into the right atrium. A transthoracic echocardiogram revealed a large right atrial mass extending from the inferior vena cava with possible attachment to the interatrial septum.

Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

One of the major issues encountered in patients undergoing evaluation for Transcatheter mitral valve replacement (TMVR) is the risk of Left ventricular outflow tract (LVOT) obstruction. LVOT obstruction is a catastrophic complication of TMVR, the result of displacement of the anterior mitral valve leaflet (AML) toward the interventricular septum. Several strategies to mitigate the risk of LVOT obstruction have been described and include percutaneous laceration of the anterior mitral leaflet (LAMPOON), alcohol septal ablation, trans-atrial leaflet modification (SITRAL) and Balloon Assisted Translocation of Mitral Anterior leaflet to prevent LVOT obstruction (BATMAN).

Background: Few studies have incorporated echocardiography and laboratory data to predict clinical outcomes in heart failure with preserved ejection fraction (HFpEF).
Objectives: This study aimed to use machine learning to find predictors of heart failure (HF) hospitalization and cardiovascular (CV) death in HFpEF.
Methods: From the Chang Gung Research Database in Taiwan, 6,092 HFpEF patients (2,898 derivation, 3,194 validation) identified between 2008 and 2017 were followed until 2019.
Early Clinical Results for a New Self-Organizing Hybrid Fabric in Congenital Cardiac Surgery.

Department of Thoracic and Cardiovascular Surgery, Osaka Medical and Pharmaceutical University, Osaka, Japan.
Background: We have developed a new hybrid warp-knit fabric for induction of in situ tissue regeneration that has shown appropriate antideterioration properties and expandability in preclinical studies. This study was performed to assess the clinical efficacy and safety of this fabric in the early postoperative period after congenital cardiac surgery.
Methods: The fabric comprises biodegradable (complete degradation period, 2-3 years) and nonbiodegradable yarns coated with cross-linked gelatin.
