Review
Left atrial (LA) structural and functional evaluation have recently emerged as powerful biomarkers for adverse events in a variety of cardiovascular conditions. Moreover, noninvasive evaluation of LA pressure has gained importance in the characterization of the hemodynamic profile of patients. This review describes the methodology, benefits and pitfalls of measuring LA size and function by echocardiography and provides a brief overview of the prognostic utility of newer echocardiographic metrics of LA geometry and function (i.e., three-dimensional volumes, longitudinal strain, and phasic function parameters).

Left superior vena cava draining into the left atrium in the absence of coronary sinus is an anomaly that can appear in heterotaxy syndrome and unroofed coronary sinus syndrome. Regardless of the origin of these syndromes, biventricular repair can be done through rerouting by intracardiac procedures or through disconnection-reconnection of the left superior vena cava to the right atrium or right superior vena cava by extracardiac procedures. Different techniques can be used for this purpose, each of which has its own advantages and limitations. Therefore, appropriate selection is necessary to obtain the best results for each patient, and many factors, such as patient anatomy, age, associated cardiomyopathies, etc., have to be considered. In this review, we focus on heterotaxy and unroofed coronary sinus syndromes, associated cardiomyopathies, the state-of-the-art in their surgical treatment and our results in a sample of 10 patients. Our experience highlights the importance of accurate diagnosis and specific selection of surgical technique for the management of biventricular repair in patients with left superior vena cava draining into the left atrium in the absence of coronary sinus.

Background The lateral left atrium (LA) is often associated with atrial tachycardia (AT) because of its complex anatomy. We sought to characterize ATs associated with the lateral LA, including the posterolateral mitral isthmus (MI) and left atrial ridge. Methods and Results Twenty-eight lateral LA-associated ATs were mapped with high-resolution mapping systems and entrainment pacing. The vein of Marshall was mapped with a 1.8-Fr mapping catheter when possible. ATs were associated with the posterolateral MI in 18 ATs (14 perimitral, 3 small reentry, and 1 focal AT). All patients had undergone MI area ablation, and all ATs were successfully eliminated. During 27.0 (interquartile range, 10.5-40.0) months of follow-up, all were free from any atrial tachyarrhythmias, with 3 patients on antiarrhythmics. Of 10 ATs involving the ridge or Marshall bundle, 3 were ridge related, 3 were Marshall bundle related based on vein of Marshall mapping, and 1 was a persistent left superior vena cava related AT. All 7 patients had undergone MI linear ablation. The critical isthmus was in the LA-ridge junction or the LA-Marshall bundle junction. Bidirectional conduction block between the LA and ridge or Marshall bundle was created. Two patients had the critical isthmus in the other area. The remaining patient had micro-reentry in the ridge. All 10 ATs were terminated during ablation at the critical isthmus. During 12.0 (5.2-31.7) months of follow-up, all were free from any atrial tachyarrhythmias, with 7 patients on antiarrhythmics. Conclusions Most ATs occurred after MI area ablation. An high resolution mapping-guided approach is highly effective for identifying the mechanism.

Review
Atrial fibrillation is associated with neurocognitive comorbidities such as stroke and dementia. Evidence suggests that rhythm control-especially if implemented early-may reduce the risk of cognitive decline. Catheter ablation is highly efficacious for restoring sinus rhythm in the setting of atrial fibrillation; however, ablation within the left atrium has been shown to result in MRI-detected silent cerebral lesions. In this state-of-the-art review article, we discuss the balance of risk between left atrial ablation and rhythm control. We highlight suggestions to lower the risk, as well as the evidence behind newer forms of ablation such as very high power short duration radiofrequency ablation and pulsed field ablation.
