BACKGROUND: In patients with hypertrophic cardiomyopathy (HCM), enlargement of the left atrium (LA) is associated with increased morbidity and mortality due to risk of atrial fibrillation (AF), stroke, and heart failure. In this study, we investigated whether LA reverse remodeling occurs following septal myectomy. METHODS: Between March 2007 and July 2015, 656 patients underwent myectomy at our institution and had pre- and postoperative transthoracic echocardiographic (TTE) recording of LA volume index (LAVI)...

AIM: Pulmonary thromboendarterectomy (PTE) is a recognized treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), with good long-term haemodynamic results. The aim of this study was to test the hypothesis that the dynamics of health-related quality of life (QoL), 1 year after PTE, depends both on the clinical determinants associated with the underlying disease and the adverse events occurring in the early postoperative period. METHODS: This prospective cohort study included 136 patients with CTEPH...

BACKGROUND: Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement (DVR: aortic and mitral valve replacement) remains unexamined. MATERIALS AND METHODS: We conducted a retrospective review of 238 patients with AF who underwent DVR with or without concomitant surgical ablation (Ablation group, n=113; Non-ablation group, n=125) at a single institute from April 2006 to September 2011...

OBJECTIVES: Atrial fibrillation (AF) reduces survival and quality of life (QoL). It can be treated at the time of major cardiac surgery using ablation procedures ranging from simple pulmonary vein isolation to a full maze procedure. The aim of this study is to evaluate the impact of adjunct AF surgery as currently performed on sinus rhythm (SR) restoration, survival, QoL and cost-effectiveness. METHODS: In a multicentre, Phase III, pragmatic, double-blinded, parallel-armed randomized controlled trial, 352 cardiac surgery patients with >3 months of documented AF were randomized to surgery with or without adjunct maze or similar AF ablation between 2009 and 2014...

OBJECTIVES: Surgical ablation of atrial fibrillation (AF) aims to restore normal sinus rhythm while protecting the sinus node from surgical damage. Surgical lesions may affect autonomic neural structures and influence physiological heart rate variability (HRV). The primary aim of this study was to describe long-term dynamics of HRV after successful surgical ablation of AF. The secondary aim was to compare sinus node function after successful ablation of AF with either left atrial modified Maze procedure or epicardial pulmonary vein isolation after long-term follow-up...

A 76-year-old woman who had been on hemodialysis for 3 years developed ischemic mitral valve insufficiency, tricuspid insufficiency, and chronic atrial fibrillation, and underwent cardiac surgery. On the 4th postoperative day, she experienced a sudden disturbance of consciousness, aphasia, and limb ataxia. Brain computed tomography and magnetic resonance imaging showed no abnormalities. Wernicke's encephalopathy was suspected and the patient was given vitamin B1, whereupon her symptoms gradually improved. On the 42nd postoperative day, she was free of neurological symptoms and discharged...

PURPOSE: The Multicenter Study of Perioperative Ischemia (McSPI) AFRisk index predicts postoperative atrial fibrillation (POAF) after cardiac surgery, but requires pre-, intra-, and postoperative data. Other more abbreviated risk indices exist, but there is no consensus on which risk index is optimal. We compared the discriminatory capacity of the McSPI AFRisk index with three indices containing only preoperative data (the CHA2 DS2 Vasc score, POAF score, and Kolek clinical risk prediction model), hypothesizing that the McSPI AFRisk index would have superior predictive capacity...
