Intraoperative transesophageal echocardiography is a minimally invasive monitoring tool that can provide real-time visual information on ventricular function and hemodynamic volume status in patients undergoing liver transplantation. The American Association for the Study of Liver Diseases states that transesophageal echocardiography should be used in all liver transplant candidates in order to assess chamber sizes, hypertrophy, systolic and diastolic function, valvular function, and left ventricle outflow tract obstruction...

Echocardiography revealed 2 aneurysms in the mitral valve with mitral regurgitation and aortic regurgitation,in a 42-years-old man. He had had infective endocarditis due to Streptococcus 9 months before. A prolapse in the right coronary cusp without vegetation and 2 aneurysms in the anterior mitral leaflet were found intraoperatively. Aortic valve was replaced, and then mitral aneurysms were resected and repaired using his own pericardium. There has been almost no regurgitation or recurrence of infection over 3 years...

A 6-year-old boy (weight 15.5 kg) underwent pulmonary valve plasty using autologous pericardium. He received a diagnosis of aortic coarctation and ventricular septal defect. Total correction was performed at the age of 18 days ( weight 2.2 kg). Intraoperatively, to confirm the position of the ventricular septum defect, we needed to incise from the main pulmonary artery to right ventricle through a commissure part of pulmonary valve. Although he exhibited stable hemodynamics, pulmonary valve regurgitation progressed...

Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

Transesophageal echocardiography (TEE) was first used routinely in the operating rooms in the 1980s to facilitate surgical decision-making. Since then, TEE has evolved from the standard two-dimensional (2D) exam to include focused real-time three-dimensional (RT-3D) imaging both inside and outside the operating rooms. Improved spatial and temporal resolution due to technological advances has expedited surgical interventions in diseased valves. 3D imaging has also emerged as a crucial adjunct in percutaneous interventions for structural heart disease...

BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

Background Transcatheter aortic valve implantation has been established as a safe and effective treatment option for patients at high or prohibitive surgical risk. However, some patients may not be suitable for the transfemoral approach due to severe iliofemoral disease or aneurysmal disease of the thoracoabdominal aorta. The aim of this case series was to evaluate the feasibility and clinical outcomes of the transaortic approach. Methods From May 2015 to June 2016, 5 patients (mean age 78.4 ± 3.9 years) with severe symptomatic aortic stenosis underwent transaortic transcatheter aortic valve implantation after a heart team discussion...

Background: General anaesthesia and surgically induced changes in cardiac loading conditions may alter flow across the aortic valve. This study examined how echocardiographic assessment of the severity of aortic stenosis (AS) changes during surgery. Methods: Patients who underwent aortic valve replacement for any severity of AS between July 2007 and June 2015 were identified. Peak velocities, mean gradients, and dimensionless indices (DI) measured with preoperative transthoracic echocardiography (TTE) were compared with those measured with intraoperative transoesophageal echocardiography (TOE)...

OBJECTIVES: Right heart failure (RHF) after the implantation of a left ventricular assist device (LVAD) remains a dreaded postoperative complication. Using 2D speckle-tracking echocardiography, it is possible to acquire right ventricular global and regional function. The aim of our study was to assess whether speckle-tracking echocardiography values will better predict the RHF post-continuous-flow LVAD implantation. METHODS: From January 2014 to January 2016, 54 patients who underwent LVAD implantation were included and retrospectively analysed...

It is well known that myocardial ischemia leads to Regional Wall Motion Abnormalities (RWMAs) and reversible depression of Left Ventricular (LV) systolic function. Transoesophageal Echocardiography (TEE) is an established tool for early diagnosis of new RWMAs. However, evaluation of RWMAs by echocardiography is largely qualitative and relies on visual assessment of wall segments. Evaluation of LV systolic function and Ejection Fraction (EF) is more reproducible and accurate with Real-Time 3D Echocardiography (RT3DE) as compared with two-dimensional and M-mode techniques...

Adult patients with repaired congenital heart disease are presenting with previously unseen types of residual lesions and consequences of prior repair. Patients with d-transposition of the great arteries repaired with atrial switch operations are returning with dysrhythmias and atrioventricular valve disease requiring intervention. We present the challenging case of a young adult with a residual shunt identified on preoperative three-dimensional transthoracic echocardiography, the precise anatomy of which was only characterized intraoperatively...

Aortopulmonary window (APW) is a relatively rare cardiac lesion representing approximately 0.2%-0.4% of all cardiac malformation. It is a cardiac abnormality that results from abnormal communication between the proximal aorta and the main pulmonary artery in the presence of two normally separated aortic and pulmonary valves. In the past, the diagnostic and surgical approach to APW was almost always preceded by cardiac catheterization. With recent advances in noninvasive approach and techniques of two-dimensional echocardiography diagnosis of the defect and associated anomalies are facilitated without a cath study...

Subramanian Chellappan, Balaswaroop Sahu, Yogesh C Sathe
Double-chambered right ventricle (DCRV) is a developmental cardiac anomaly in which anomalous muscle bundles divide the right ventricular (RV) cavity into two chambers. It is usually associated with other congenital cardiac defects, of which ventricular septal defect is the most common association. Isolated DCRV with an intact interventricular septum is very rarely reported. It manifests itself usually in adolescence and adults as the obstruction progresses gradually. It is important to recognize this anomaly as it can progress to severe RV failure if unaddressed...

Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valves has been successfully performed, but there is a lack of published experience in percutaneous treatment of patients with unicuspid valves and severe aortic stenosis. We describe a case of TAVR in such a patient. A 31-year-old woman with Turner syndrome-who had undergone coarctation repair via subclavian flap at age 7 days and an aortic valvotomy at age 6 weeks-presented with severe symptomatic aortic stenosis. She was deemed inoperable because of her severe pulmonary hypertension and numerous comorbidities; consequently, a 20-mm Edwards Sapien 3 Transcatheter Heart Valve was offered for compassionate use...

In a healthy 12-year-old female with scoliosis, prone positioning resulted in pressor-refractory cardiovascular collapse. Resumption of supine position immediately improved hemodynamics. Intraoperative transesophageal echocardiography (TEE) revealed a collapsed left atrium and biventricular failure. Repeat prone positioning resulted in a recurrence of hypotension. However, hemodynamic stabilization was restored and maintained by repositioning chest pads caudally. The patient successfully underwent a 6-hour scoliosis repair without perioperative morbidity...

We report obstruction of the left ventricle outflow tract (LVOT) caused by cardiac myxoma that was misidentified as an accessory mitral valve tissue preoperatively. A 65-year-old woman presented with chest discomfort that persisted for 7 days. Transthoracic echocardiography (TTE) revealed a mobile, low-echogenic, balloon-shaped mass attached to the anterior mitral valve leaflet and papillary muscle, which was suspected to be an accessory mitral valve tissue. Because the mass caused LVOT obstruction and it could result in hemodynamic instability, emergency operation was performed...
