Impact of atrial fibrillation ablation on left ventricular filling pressure and left atrial remodeling.

Background: Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process.

Objective: To evaluate the impact of AF ablation on estimated LV filling pressure.

Sudden cardiac arrest in general anesthesia as the first manifestation of anomalous origin of the left coronary artery.

Background And Objectives: This case report describes a rare and potentially fatal condition associated with anesthesia administration. Our aim was to discuss the causes of sudden cardiac arrest during the perioperative period in apparently healthy patients and the pathophysiology of anomalous origin of the coronary arteries as a cause of sudden cardiac arrest.

Case Report: Female patient, 44 years old, with no previous symptoms of heart disease or arrhythmias, had a sudden cardiac arrest during general anesthesia in two different situations.

[Renal resistance index predicting outcome of renal revascularization for renovascular hypertension].

Background: Renal artery stenosis (RAS) is a potentially correctable cause of hypertension and ischemic nephropathy. Despite successful renal revascularization, not all patients (pt) overcome it and some get worse.

Objective: This study was designed to assess the value of renal resistance index (RI) in predicting the outcome of renal revascularization.
