Eighteen patients underwent surgery for intracardiac myxoma (16 left atrial and 2 right atrial) during the last 10 years. Seventeen patients had tumour stalk attached to the oval fossa. The myxoma was excised along with a cuff of the atrial septum, which was reconstructed using a Dacron patch in 15 patients and by direct suture in 2 patients. In the remaining case the myxoma was attached to the left atrial wall and adjacent atrioventricular junction. There was only one early death in a patient who underwent a concomitant lobectomy for lung abscess and one late death due to a noncardiac cause. During the follow-up period of 3-96 months (average 36 months) all the survivors were in New York Heart Association Class I. Scanning electron microscopy of tumour tissue was done in 8 cases. The morphological findings did not help in categorizing the tumours into any pathological subgroups. Postoperative cardiac catheterization done in 3 patients (30-50 months postoperatively) showed return of haemodynamics to normal. Echocardiographic studies done postoperatively have not revealed recurrence of tumour in any patient. Surgical excision of myxomas is possible with very gratifying long-term results.

Aims: Inter-atrial shunt device therapy has shown mixed results in clinical trials, with clinical 'non-responders' typically showing features of more advanced heart failure. We aimed to analyse the haemodynamic and clinical response of a novel left atrial to coronary sinus (LA-CS) shunt device in patients with higher natriuretic peptide (NP) levels, a marker of disease severity.
Methods And Results: An analysis population (n = 95) of patients from the ALT-FLOW early feasibility study with left ventricular ejection fraction >40% and 1-year follow up was analysed.

The aim of this study was to analyze the correlation between left ventricular mass index (LVMI) and the prognosis of patients with acute myocardial infarction (AMI).The study retrospectively analyzed the Registry of New-onset Atrial Fibrillation Complicating Acute Myocardial Infarction-Shanghai database and included 1957 patients with AMI who were hospitalized from February 2014 to March 2018, with a median follow-up of 2.7 ± 1.

Objective: To evaluate the safety, efficacy, and long-term effects of catheter ablation with vein of Marshall ethanol infusion for bidirectional mitral isthmus block in patients with persistent atrial fibrillation.
Methods: Two hundred and forty patients from five centers with persistent atrial fibrillation (AF) who underwent radiofrequency ablation from October 2018 to December 2023 were retrospectively analyzed, including 120 patients who underwent traditional pulmonary vein isolation (PVI Only group) and 120 patients who underwent PVI and Marshall vein ablation (Marshall Plus group). The operation time, X-ray exposure, incidence of AF/atrial tachycardia (AT) and complications were compared between the two groups.

Background: The role of prophylactic concomitant left atrial appendage closure during mitral repair in patients without atrial fibrillation (AF) is not defined.
Objectives: The objective was to compare long-term outcomes of patients who had left atrial appendage closure during mitral repair with those who did not in patients without AF.
Methods: A large national registry was used to identify 38,597 patients undergoing isolated mitral repair from 2010 to 2019.

This consensus statement is the product of a workshop at the South Pacific Underwater Medicine Society Annual Scientific Meeting 2024 with representation of the United Kingdom Diving Medical Committee (UKDMC) present, and subsequent discussions included the entire UKDMC. A large right-to-left shunt across a persistent (patent) foramen ovale (PFO), an atrial septal defect (ASD) or a pulmonary shunt is a risk factor for some types of decompression sickness (DCS). It is agreed that routine screening for a right-to-left shunt is not currently justifiable, but certain high risk sub-groups can be identified.
