ABSTRACT. Catheter ablation of atrial fibrillation (AF) is a widely recommended treatment for patients presenting with symptomatic AF refractory to pharmacological treatment. AF ablation is also becoming a therapeutic option for patients with chronic heart failure (CHF), on top of optimal medical treatment, as AF is related to a higher risk of death, the worsening of symptoms, and the progression of CHF in this patient cohort. The present systematic review describes all published experiences concerning the use of AF catheter ablation among CHF patients and/or patients with structural cardiomyopathies, in an effort to summarize procedural safety and efficacy in this specific setting. Moreover, the effects of AF ablation on functional class and quality of life, as well as the different procedural protocols available, are presented and discussed, aiming to provide an evidence-based clinical perspective to optimize indication and tailor procedural characteristics and endpoints to patients affected by CHF referred for AF ablation.

“…After a transseptal catheterization, the pressure was measured during sinus rhythm through an 8.5-French sheath inserted into the LA with a hemodynamic monitoring system (Cardio Master, Nihon Koden, Tokyo, Japan). The LA peak A-wave pressure, LA peak V-wave pressure, and mean LA pressure were recorded (14). The central venous pressure was then measured using a 8.0-French sheath advanced into the right atrium.…”

BackgroundThe impact of subclinical hypothyroidism on the cardiovascular risk is still debated. We aimed to measure the relationship between subclinical hypothyroidism and the left atrial (LA) pressure.MethodsThe LA pressures and thyroid function were measured in consecutive patients undergoing atrial fibrillation (AF) ablation, who did not have any known heart failure, structural heart disease, or overt thyroid disease.ResultsSubclinical hypothyroidism (4.5≤ thyroid-stimulating hormone <19.9 mIU/L) was present in 61 (13.0%) of the 471 patients included. More subclinical hypothyroidism patients than euthyroid patients (55.7% vs 40.2%; P=0.04).’euthyroid patients had persistent or long-standing persistent AF (55.7% vs 40.2%; P = 0.04). The mean LA pressure (10.9 ± 4.7 vs 9.1 ± 4.3 mmHg; P = 0.002) and LA V-wave pressure (17.4 ± 6.5 vs 14.3 ± 5.9 mmHg; P < 0.001) were, respectively, higher in the patients with subclinical hypothyroidism than in the euthyroid patients. After an adjustment for potential confounders, the LA pressures remained significantly higher in the subclinical hypothyroidism patients. A multiple logistic regression model showed that subclinical hypothyroidism was independently associated with a mean LA pressure of >18 mmHg (odds ratio 3.94, 95% CI 1.28 11.2; P = 0.02).ConclusionsSubclinical hypothyroidism may increase the LA pressure in AF patients.

Key Clinical MessageWe describe the case that persistent atrial fibrillation refractory to rhythm control by pharmacotherapy and electrical cardioversions caused tachycardia‐induced cardiomyopathy with low ejection fraction and hemodynamic instability. Mechanical hemodynamic support using an intra‐aortic balloon pump is one of the choices of hemodynamic support during catheter ablation by pulmonary vein isolation.

Incomplete Cure of Tachycardia‐Induced Cardiomyopathy Secondary to Rapid Atrial Fibrillation by Heart Rate Control Without Sinus Conversion

Abstract: Heart rate control during AF without sinus conversion may result in an incomplete cure of TIC, suggesting the advantages of rhythm control with ablation in patients with TIC.
