Poonam Malhotra Kapoor, Kanchi Muralidhar, Navin C Nanda, Yatin Mehta, Naman Shastry, Kalpana Irpachi, Aditya Baloria
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...

This is a practical description of how replacement valves are assessed using echocardiography. Normal transthoracic appearances including normal variants are described. The problem of differentiating normal function, patient-prosthesis mismatch and pathological obstruction in aortic replacement valves with high gradients is discussed. Obstruction and abnormal regurgitation is described for valves in the aortic, mitral and right-sided positions and when to use echocardiography in suspected infective endocarditis...

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 enoxaparin-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...

CLINICAL INTRODUCTION: A 55-year-old West African man was referred for routine echocardiography. He was completely asymptomatic, a non-smoker, working out at the gym several times weekly. He was taking hydrochlorothiazide for hypertension.Clinical examination revealed a blood pressure of 156/74 mm Hg and systolic and diastolic murmurs suggestive of aortic insufficiency. Pulses were equal bilaterally and he had no marfanoid features or hyperelasticity. ECG showed mild left ventricular hypertrophy and chest X-ray revealed a normal cardiac shadow and mediastinum...

Left ventricular assist device (LVAD) implantation can be challenging in patients with a prior surgical ventricular restoration (SVR). In this case series of heart failure patients with a history of SVR, we describe the surgical technique and outcome of a customized approach for inflow cannula orientation. Seven patients with a history of SVR with end-stage chronic heart failure were accepted for long-term LVAD support. In all patients, the Dacron patch was removed through left ventriculotomy and a Hegar 22 dilator was inserted at the estimated optimal position of the LVAD inflow cannula...

We present a case of sinus venosus atrial septal defect in a patient who was previously diagnosed as having primary pulmonary hypertension in a tertiary care center. Our findings are based on 2-dimensional trans-thoracic echocardiography, chest X-ray and surface electrocardiogram. A 26-year-old man, previously diagnosed as a case of primary pulmonary hypertension, presented to the emergency department (ED) with chest pain and breathlessness on exertion. Cardiac biomarkers were within their normal ranges. Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation...

Transcatheter aortic valve implantation (TAVI) was introduced as an alternative treatment for patients with severe symptomatic aortic stenosis for whom surgery would be high-risk. Prosthetic aortic valve endocarditis is a serious complication of surgical AVR (SAVR) with high morbidity and mortality. According to recent cases, post-TAVI prosthetic valve endocarditis (PVE) seems to occur very rarely. We present the case of a 75-year-old woman who underwent TAVI (Edwards Saphien XT) with an uneventful postoperative stay...

AIMS: Pulmonary veins (PVs) isolation is the cornerstone of atrial fibrillation (AF) ablation and can be achieved either by conventional radiofrequency ablation or by cryoenergy. Left atrial appendage (LAA) closure has been proposed as alternative treatment to vitamin K antagonists (VKA). We aimed to evaluate the feasibility of combining cryoballoon (CB) ablation and LAA occlusion in patients with AF and a high thromboembolic risk or contraindication to antithrombotic therapy. METHODS AND RESULTS: Thirty-five patients (28 males, 74 ± 2 years) underwent CB ablation...

Transthoracic and transoesophageal echocardiography are increasingly used as tools to improve clinical assessment following cardiac surgery. However, most physicians are not trained in echocardiography, and there is no widespread agreement on the feasibility, indications or effect on outcome of transthoracic or transoesophageal echocardiography for patients after cardiac surgery. We performed a systematic review of electronic databases for focused transthoracic and transoesophageal echocardiography after cardiac surgery which revealed 15 full-text articles...

Cardiac ultrasound allows comprehensive analysis of the complex structure of the mitral valve. Transoesophageal echocardiography is the preferred diagnostic and monitoring technique both in the intraoperative phase and in the immediate postoperative phase. Besides two-dimensional imaging, the 3D approach offers clear advantages in visualizing different aspects of pathology and facilitating interpretation of pathophysiological features. This review comprehensively summarizes anatomical and physiological characteristics, the value of 2D imaging in diagnosis and follow-up and the supplementary significance of 3D echocardiography...
