In end stage renal disease patients on dialysis, the use of catheter as a vascular access is associated with a significant risk of sepsis compared to an arterio-venous fistula. Our case emphasizes the importance of having high index of suspicion for unusual complications in patients presenting with possible catheter-related blood stream infection and early use of complementary tools such as trans-oesophageal echocardiography whenever applicable.

BACKGROUND: Fluoroless transseptal (TS) puncture may represent the final step towards elimination of fluoroscopy in pediatric supraventricular tachycardia ablation in normal hearts. We aimed to demonstrate the safety and feasibility of fluoroless TS puncture in pediatric patients and compare procedural timing with the fluoroscopic approach. METHODS: We performed a retrospective cohort analysis of all TS procedures performed without fluoroscopy at our institution; fluoroless TS procedures were performed under intracardiac echocardiography (ICE) guidance after creation of 3D electroanatomic map and identification of fossa ovalis on 3D map...

INTRODUCTION: Structural heart interventions are guided by transoesophageal or intracardiac echocardiography (TEE/ICE). MicroTEE, developed for paediatric purposes, is smaller and therefore less invasive and traumatic, avoiding the need for general anaesthesia. We aimed to show feasibility of procedural guidance by comparing image quality of microTEE with standard TEE and ICE during adult transcatheter interventions, and assess the accuracy in obtaining left atrial appendage (LAA) measurements between the microTEE probe and standard TEE...

Transcatheter closure of atrial septal defects and patent foramen ovale has become increasingly common with advances in device and imaging technology. The percutaneous approach is now the preferred method of closure when anatomically suitable. Two-dimensional and 3-dimensional echocardiography determines anatomic suitability by characterizing the interatrial defect and its surrounding structures, and is critical for intraprocedural guidance and postprocedure follow-up. This article provides an overview of interatrial anatomy as it pertains to interventional considerations and discusses the transthoracic, transesophageal, and intracardiac echocardiographic modalities used for periprocedural and intraprocedural imaging of the interatrial septum...

INTRODUCTION: Frequent ventricular premature complexes (VPCs) may cause symptoms and/or lead to deterioration of LV systolic function. Although frequent VPCs may be abolished by catheter ablation, it may be challenging in case of their origin from the LV papillary muscles (PMs). Our collaborative study aimed to analyze in detail the site of origin and the outcome of ablation. METHODS: Consecutive 34 patients (males: 68%; aged 62±12 years; LV ejection fraction: 50±9%) undergoing catheter ablation of VPCs originating from PMs were included...

Intracavitary cardiac extension remains an unusual site of extrahepatic metastasis in patients with hepatocellular carcinoma. While patients can present with signs and symptoms suggestive of right-sided heart failure, it may be totally asymptomatic, which is very rare with only a few cases reported so far. Also, cardiac metastasis is of great prognostic importance as patients with intracardiac metastasis can have an extremely poor prognosis. Here, we present the case of a 52-year-old male patient with advanced hepatocellular carcinoma, with an incidentally found tumor thrombus extending from the inferior vena cava to the right atrium, protruding through the tricuspid valve into the right ventricle, on routine echocardiography...

Background Retrograde embolism from the descending thoracic aorta is one possible cause of undetermined ischemic stroke. Significant aortic regurgitation can increase the amount of reversed flow in the thoracic aorta and thus is associated with an increased incidence of stroke. Aims This study aimed to examine the association between significant aortic regurgitation and undetermined embolic infarction with aortic complex plaques. Methods This study included 380 patients with undetermined embolic stroke who did not have abnormal flow such as atrial septal defect, patent foramen ovale determined by agitated saline bubble test, intracardiac thrombi on transesophageal echocardiography, atrial fibrillation, or small vessel stroke, cerebral artery, and carotid stenosis on the brain magnetic resonance imaging...

A 68-year-old woman with a history of bipolar disorder was admitted to another hospital with a gastric ulcer. On admission, Takotsubo cardiomyopathy was suspected because her electrocardiogram was abnormal and the characteristic left ventricular wall motion was apparent. On hospital day 11, echocardiography revealed a thrombus in the apex of the left ventricle. She was transferred to our hospital and heparin treatment was commenced. On follow-up echocardiography, the left ventricular wall motion had normalized but thrombus mobility had increased...

OBJECTIVES: The aim of this study was to compare the efficacy and safety of intracardiac echocardiography (ICE) from the left atrium (LA) with transesophageal echocardiography (TEE) for procedural guidance of transcatheter left atrial appendage occlusion (LAAO). BACKGROUND: TEE with general anesthesia is the current gold standard to guide LAAO. By the use of ICE from the LA, LAAO can be performed in local anesthesia and may potentially have advantages over TEE. METHODS: A single-center, cohort study of patients undergoing LAAO with the Amplatzer Cardiac Plug or Amulet (St...

PURPOSE: There remains a paucity of direct visualization techniques for beating-heart intracardiac procedures. To address this need, we evaluated a novel cardioscope in the context of aortic paravalvular leaks (PVLs) localization and closure. DESCRIPTION: A porcine aortic PVL model was created using a custom-made bioprosthetic valve, and PVL presence was verified by epicardial echocardiography. Transapical delivery of occlusion devices guided solely by cardioscopy was attempted 13 times in a total of three pigs...

OBJECTIVE: This registry aimed to describe the safety and feasibility of a single trans-septal (TS) access technique for left intracardiac echocardiography (ICE) guidance of left-atrial appendage (LAA) closure procedure. BACKGROUND: LAA closure is currently accepted as an alternative to oral anticoagulation (OAC) in patients with non-valvular atrial fibrillation (NVAF) who are at high-risk for bleeding. Currently, LAA closure procedure is typically performed under trans-esophageal echocardiogram (TEE) guidance...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

For left atrial appendage occlusion (LAAO), intracardiac echocardiography (ICE) could be a safe alternative to transesophageal echocardiography (TEE). ICE obviates the need for general anesthesia and can be readily implemented in practice. Randomized controlled trials are needed to assess the noninferiority of ICE to TEE for LAAO.

OBJECTIVES: Acute lower limb ischemia caused by tumor embolization is rare, despite the fact that cancer is a common cause of hypercoagulability predisposing to venous thrombosis. Arterial embolization is mostly associated with intracardiac tumors while lung malignancies are the second most common cause of tumor embolism. METHODS: In this report, we present a male patient who developed acute bilateral lower limb ischemia in the immediate postoperative period after a thoracotomy for attempted left upper lobe resection for lung cancer...

Dilated cardiomyopathy (DCM) may be associated with formation of intracardiac thrombi which may embolize and result in life-threatening complications. We present a 19-month-old female child with DCM who presented with a right hemispheric cerebrovascular accident. Urgent echocardiography revealed poor left ventricular systolic function and a thrombus attached to the interventricular septum along the left ventricular outflow tract. There was resolution of the thrombus following the use of warfarin.
