AIMS: Percutaneous left atrial appendage closure (LAAC) is a valuable treatment option for stroke prevention in patients with atrial fibrillation and a HAS-BLED-Score ≥ 3. Determinants of procedural safety events and neurological outcome of the patients with the Occlutech Device (OD) are not established yet. METHODS AND RESULTS: Between 2012 and 2016, 30 patients underwent LAAC using the OD. This is a prospective, study. Neurological examination and transesophageal echocardiography was performed directly before and after the procedure and after 1, 3 and 12 months...

AIMS: Non-fluoroscopic catheter ablation is becoming routine. In experienced centres, fluoroscopy is rarely required. The use of a traditional catheterization lab (cath lab) may no longer be necessary. We began performing catheter ablations at a paediatric centre outside the traditional cardiac cath lab in 2013. The purpose of this study was to compare procedural features of paediatric catheter ablation performed outside the cath lab to those performed within a cath lab. METHODS AND RESULTS: We prospectively looked at patients presenting to the paediatric centre with supraventricular tachycardia (SVT) undergoing catheter ablation outside the cath lab in a standard operating room (OR group)...

Lutembacher syndrome is defined as a combination of congenital Atrial Septal Defect (ASD) with an acquired Mitral Stenosis (MS). There are various challenges involved in the percutaneous management of Lutembacher syndrome. Here, we present a case that had a very small Left Atrium (LA) and Left Ventricle (LV) cavities with an anteriorly placed ASD. We used Transoesophageal echocardiography (TEE) to take a separate interatrial septal puncture and complete the Balloon Mitral Valvotomy (BMV) procedure. Finally both the defects in interatrial septum were closed with the help of a large device...

BACKGROUND: Atelectasis after cardiopulmonary bypass (CPB) can affect right ventricular (RV) performance by increasing its outflow impedance. OBJECTIVE: The aim of this study was to determine whether a lung recruitment manoeuvre improves RV function by re-aerating the lung after CPB. DESIGN: Randomised controlled study. SETTING: Single-institution study, community hospital, Córdoba, Argentina. PATIENTS: Forty anaesthetised patients with New York Heart Association class I or II, preoperative left ventricular ejection fraction at least 50% and Euroscore 6 or less scheduled for cardiac surgery with CPB...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...

INTRODUCTION: In response to an ultrasound imaging issue with transoesophageal echocardiography probes, a testing protocol was developed to check features pertinent to the operation of these probes. The imaging problem was detected in multiple probes of the same make and model. METHODS: Over a two-year period, a series of 26 probes of this model were tested at acceptance, then three to six months later before being replaced due to a defect. A range of visual, mechanical and electrical tests were performed...

We report the first case of infective endocarditis caused by Paenibacillus provencensis. A mitral valve vegetation was incidentally discovered by intraoperative transoesophageal echocardiography in a 70-year-old woman undergoing aortic valve replacement. The precise identification of the causative agent was by means of genotypic characterisation with 16S rDNA gene sequencing. The patient was successfully treated with a 6-week course of antibiotics postoperatively, following debridement of the valve vegetation...

In 1980, Transesophageal Echocardiography (TEE) first technology has introduced the standard of practice for most cardiac operating rooms to facilitate surgical decision making. Transoesophageal echocardiography as a diagnostic tool is now an integral part of intraoperative monitoring practice of cardiac anaesthesiology. Practice guidelines for perioperative transesophageal echocardiography are systematically developed recommendations that assist in the management of surgical patients, were developed by Indian Association of Cardiac Anaesthesiologists (IACTA)...

There is a strong association between pre-operative diastolic dysfunction and difficulty in weaning from cardiopulmonary bypass. We compared the effects of propofol and isoflurane on left ventricular diastolic function in patients with pre-existing diastolic dysfunction undergoing coronary artery bypass grafting. We randomly allocated 60 patients to receive either propofol or isoflurane anaesthesia, and assessed left ventricular diastolic function using transoesophageal echocardiography. We measured early (E), late (A) diastolic velocities, E/A ratio, A-wave duration and deceleration time using pulsed wave Doppler, and early (Em), late (Am) diastolic velocities of the mitral annulus, Em/Am ratio and isovolumetric relaxation time using tissue Doppler...

We present the primary report of a paediatric patient who had placement of the MitraClip device for severe functional mitral regurgitation. The patient was a 14-year-old boy with symptomatic end-stage non-compaction type cardiomyopathy secondary to a mitochondrial cytopathy. He had severe mitral regurgitation, tricuspid valve regurgitation, a severely dilated LV with apical non-compaction, severe LV dysfunction and severe pulmonary hypertension. Despite optimal medical therapy he developed progressive symptoms of congestive heart failure and he was not a candidate for an assist device or cardiac transplantation...

OBJECTIVES: Mitral valve repair performed by an experienced surgeon is superior to mitral valve replacement for degenerative mitral valve disease; however, many surgeons are still deterred from adapting this procedure because of a steep learning curve. Simulation-based training and planning could improve the surgical performance and reduce the learning curve. The aim of this study was to develop a patient-specific simulation for mitral valve repair and provide a proof of concept of personalized medicine in a patient prospectively planned for mitral valve surgery...

AIMS: It has been hypothesized that in response to dilation of the aortic root, the aortic valve cusps may remodel to prevent aortic regurgitation (AR). The aim of the present study was to evaluate the association between aortic cusp dimensions and aortic root geometry. METHODS AND RESULTS: Three-dimensional transoesophageal echocardiography was performed in 40 patients with aortic root dilation (mean age 57 ± 12 years, 75% men, 35% bicuspid aortic valve) and 20 controls with a normal aortic root (mean age 61 ± 13 years, 65% men)...

For accurate spectral Doppler valvular evaluation, intraoperative sonographers must use transoesophageal echocardiographic (TOE) views that offer optimal incident angles. We hypothesised that views added to the 2013 American Society of Echocardiography/Society of Cardiovascular Anesthesiologists (ASE/SCA) standard views and other novel views we have described of the tricuspid (TV) and pulmonary valves (PV) offered superior incident angles to those included in the original 1999 ASE/SCA recommendations for comprehensive intraoperative TOE examination...

BACKGROUND: Edoxaban, an oral factor Xa inhibitor, is non-inferior for prevention of stroke and systemic embolism in patients with atrial fibrillation and is associated with less bleeding than well controlled warfarin therapy. Few safety data about edoxaban in patients undergoing electrical cardioversion are available. METHODS: We did a multicentre, prospective, randomised, open-label, blinded-endpoint evaluation trial in 19 countries with 239 sites comparing edoxaban 60 mg per day with enoxaparin-warfarin in patients undergoing electrical cardioversion of non-valvular atrial fibrillation...
