Seven patients underwent pericardial patch closure of the left atrial appendage orifice in our clinic. Usually 5-to-7 U-sutures with 4-0 prolene were placed to the left atrial appendage orifice. These sutures were stretched out to measure exact sizes of the left atrial appendage orifice. Then, U-sutures were passed through the pericardial patch which was treated with glutaraldehyde. Pericardium was placed over the left atrial appendage orifice through the left atrium and stay sutures were tied. The upper suture was continuously sutured along the border of the orifice clockwise and tied to the lower suture. The lower suture was continuously sutured in a counter-clockwise direction and tied to the upper suture. Then, mitral valve surgery (repair or replacement) was performed.

Background: The atrial switch procedure is accompanied by a very high rate of sinus node dysfunction. Baffle stenosis is a common problem with transvenous pacemaker leads in this scenario.
Case Summary: We present a first-in-human case of a leadless pacer (LP) in the left atrium in a patient with prior atrial switch for transposition and sinus node dysfunction complicated by multiple abandoned leads, superior baffle occlusion, and failed extraction.
Comparative evaluation of left atrial size in healthy cats measured by two-dimensional echocardiography and cardiovascular MRI.

Objectives: This study aimed to assess left atrial (LA) size in healthy cats using cardiovascular MRI (cMRI) and to compare this with LA size assessed by two-dimensional echocardiography. The hypothesis was that cMRI would accurately determine LA size in domestic cats.
Methods: A prospective comparative study was performed.

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia that greatly elevates the risk of stroke. This risk increases both during and after cardiac procedures, such as coronary artery bypass grafting (CABG). There is an increasing interest in non-pharmacological treatments such as left atrial appendage occlusion (LAAO) and surgical ablation, intending to enhance both immediate and long-term postoperative results.

Atrial fibrillation (AF) ablation is associated with a lower likelihood of death and surgical heart failure (HF) interventions in patients with HF. This effect is mainly driven by reduced all cause and cardiovascular death following ablation. Ablation also results in improved left ventricular (LV) function, decreased AF burden and AF regression.
