While it has been proposed as a potential target for preventing recurrence of atrial tachyarrhythmias, it remains unclear whether electrical silence of LAPW offers additional benefits over pulmonary vein isolation (PVI) alone. We conducted a systematic review of PubMed, Medline, Embase, and Cochrane databases and identified 21 eligible studies, encompassing 1,514 patients assigned to PVI + posterior wall isolation (PWI) group and 1,629 patients assigned to PVI group. Over a median follow-up of 12 months, adjunctive PWI significantly improved the atrial tachyarrhythmia-free survival by 14% in comparison to PVI alone [relative risk (RR): 1.14, 95% confidence interval (CI): 1.04 to 1.25, p=0.004]. This improvement was mainly attributed to a pronounced benefit for patients with persistent AF. In addition, patients undergoing PVI+PWI had a longer procedure time [weighted mean difference (WMD): 23.85, 95% CI: 12.68 to 35.01, p<0.001], ablation time (WMD: 9.27, 95% CI: 5.19 to 13.54, p<0.001), and a nearly negligible increase in fluoroscopic exposure (WMD: 2.69, 95% CI: -0.23 to 5.62, p=0.071).

In patients with reduced left ventricular (LV) distensibility, chronic elevation of LV diastolic pressure is seen with a smaller than expected LV size. Accordingly, patients with HCM with severe LV diastolic dysfunction typically demonstrate left atrial (LA) dilation and a disproportionately smaller left ventricle. Therefore, we investigated the relationship between LA/LV diameter ratio, as a potential indicator of disease progression, and outcomes in patients with HCM. We included 468 patients in whom LA and LV end-diastolic diameter were successfully evaluated by echocardiography at the initial assessment. We divided the patients into two groups: those with an LA/LV diameter ratio > 1 and those with an LA/LV diameter ratio ≤ 1. We compared the HCM-related death rates between the two groups. Of the 468 patients, 96 patients (20.5 %) with HCM showed an LA/LV diameter ratio > 1.
