Aims: The transseptal approach is used for left atrial access during the ablation of atrial fibrillation (AF) and other left-sided arrhythmia substrates. Transseptal puncture (TP) is commonly performed with fluoroscopic guidance, contrast injection, and pressure monitoring. In many centres, additional techniques [intracardiac echocardiography (ICE), transoesophageal echocardiography (TEE), radiofrequency needle] are used to facilitate TP but its use adds costs. In this retrospective study, we studied the safety and complication rate when TP was routinely done with fluoroscopic guidance, contrast injection, and pressure monitoring using ICE or TEE only in selected cases...

Infective endocarditis is a serious complication occurring after percutaneous pulmonary valve replacement with a Melody valve; it is of uncertain incidence, and presents a challenging diagnosis. Vegetations may be difficult to visualise with transthoracic and transoesophageal echocardiography. We report the role of intracardiac echocardiography in this condition by confirming the prosthesis involvement.

We report the case for a 44-year-old patient without medical history, admitted in our department for bilateral acute limb ischemia (H6). The patient was hemodynamically stable and the physical examination shows limb sever ischemia (no femoral arterial pulses, coldness, cyanosis and paralysis). Abdominal CT angiography showed a complete occlusion of the infra renal abdominal aorta compatible with embolus. An embolectomy with Fogarty catheters was performed. Echocardiography showed a mass in the left atrium. Pathological examination of the material embolic confirmed the diagnosis of the cardiac myxoma...

While the etiology of ischemic stroke is heterogeneous, approximately 20%-40% of all stroke cases result from cardiac or aortic origin. Transesophageal echocardiography (TEE) has become the reference standard modality for the detection of potential sources of cerebral embolism. Because of the advances in computed tomographic (CT) technology, cardiac CT can be used in the evaluation of potential cardioembolic sources. During the past decade, cardiac CT has been tested and compared with TEE for the diagnosis of cardioembolic sources...

Primary cardiac neoplasms are rare and are usually benign myxomas and rhabdomyomas. Cardiac leiomyomas are usually seen as a part of the spectrum of intravenous leiomyomatosis or benign metastasizing leiomyoma. De novo occurrence of primary intracardiac leiomyomas (PICL) is a rarity. Herein we describe a 14-year-old boy presenting with intermittent dyspnea for 2 years, with a large right ventricular mass suggestive of myxoma on transthoracic echocardiography, without any extracardiac lesions. Histology and immunohistochemistry of the tumor excised under cardiopulmonary bypass confirmed a PICL arising at the cardiomyocyte-smooth muscle septal interface...

The development of paravalvular leak (PVL) following surgical replacement of an aortic or mitral valve is an uncommon complication with significant morbidity and mortality. Surgical or percutaneous repair of PVL can be technically challenging. We describe the application of intracardiac echocardiography guided 3-dimensional electroanatomic mapping to facilitate PVL closure in a symptomatic patient with a previously placed bioprosthetic mitral valve. © 2017 Wiley Periodicals, Inc.

BACKGROUND: This study evaluated the use of an autologous vein graft, supported by expanded polytetrafluoroethylene (ePTFE) chordae tendineae, to replace an anterior mitral valve leaflet. METHODS: A double-layered autologous jugular vein graft, supported by ePTFE chords, was used to create an anterior mitral valve leaflet in 21 sheep. Mitral valve function was monitored with echocardiography for up to 10 months. Surviving sheep were euthanized between 6 and 10 months later, and vein implants were examined histologically...

Percutaneous closure is nowadays considered the treatment of choice of ostium secundum atrial septal defects (ASD). However, transcatheter closure can be highly challenging when we face an ASD with complex morphological features. The combination of different imaging modalities can be very helpful. This case shows the great value of using both intracardiac and real time 3D transesophageal echocardiography for the percutaneous closure of a complex iatrogenic ASD after device embolization.

In recent years, the transseptal puncture approach has enabled passage of increasingly large and complex devices into the left atrium. Traditional tools remain effective in creating and dilating the initial puncture, with an acceptable safety profile. Even for skilled operators, the procedure is technically demanding and requires sound understanding of atrial anatomy. Intracardiac echocardiography is useful in cases of previous septal repair, poorly defined fossa ovalis anatomy or when considering patent foramen ovale portal crossing...

BACKGROUND: Transesophageal echocardiography (TEE) remains the gold standard for exclusion of left atrial appendage (LAA) thrombus in patients scheduled for direct electrical cardioversion (DEC) or atrial fibrillation (AF) ablation. Recently, intracardiac echocardiography (ICE) of the pulmonary artery (PA) has been shown to provide excellent LAA images and to be useful in verification of equivocal TEE findings. HYPOTHESIS: ICE of the PA may have a role in detecting false-positive TEE results...

PURPOSE OF REVIEW: This article reviews the current imaging role of (18)F-fluordeoxyglucose positron emission computed tomography ((18)F-FDG-PET/CT) combined with cardiac CT angiography (CTA) in infective endocarditis and discusses the strengths and limitations of this technique. RECENT FINDINGS: The diagnosis of infective endocarditis affecting prosthetic valves and intracardiac devices is challenging because echocardiography and, therefore, the modified Duke criteria have well-recognized limitations in this clinical scenario...

Retained intravascular foreign body is a well-known complication of central venous access placement in children as well as adults. Most of these foreign bodies are radio-opaque and hence are removed under fluoroscopy guidance. In our case, we describe the removal of an intracardiac radiolucent foreign body in an infant utilizing a combination technique - transesophageal echocardiogram and fluoroscopy.

BACKGROUND: Catheter ablations have been traditionally performed with the use of fluoroscopic guidance, which exposes the patient and staff to the inherent risks of radiation. We have developed techniques to eliminate the use of fluoroscopy during cardiac ablations and have been performing completely fluoroless catheter ablations on our patients for over 5 years. METHODS: We present a retrospective analysis of the safety, efficacy, and feasibility data from 500 consecutive patients who underwent nonfluoroscopic catheter ablation, targeting a total of 639 arrhythmias, including atrioventricular reciprocating tachycardia (AVRT), atrioventricular nodal reentrant tachycardia (AVNRT), atrial tachycardia (AT), atrial fibrillation (AF), premature ventricular contractions (PVC), and ventricular tachycardia (VT)...

BACKGROUND: First description of a technique for left atrium transseptal puncture (TSP) with minimal radiation exposure by using the nonfluoroscopic MediGuide™ tracking system (MG) without the assistance of intracardiac echocardiography. METHODS: This study included 31 consecutive patients with atrial fibrillation undergoing an MG assisted percutaneous catheter ablation procedure. A Brockenbrough transseptal needle (BRK) is connected to a standard pressure transducer through a two input valve...

Intracardiac bronchogenic cysts are uncommon congenital tumors, which rarely become symptomatic. We describe a rare case of bronchogenic cyst in the atrioventricular node. A 36-year-old man with third-degree atrioventricular block was referred to our hospital. Transthoracic echocardiography revealed a cystic mass at the right atrial aspect of the low interatrial septum. He underwent surgical resection of the mass, and a permanent epicardium pacemaker was implanted. His postoperative course was uneventful. Microscopic examination showed a cyst surrounded by ciliated columnar epithelium and partially smooth muscle, and the histopathological diagnosis was bronchogenic cyst...

We developed a 2.5 x 6.6 mm 2D array transducer with integrated transmit/receive ASIC for 4D ICE (real-time 3D IntraCardiac Echocardiography) applications. The ASIC and transducer design were optimized so that the high voltage transmit, low-voltage TGC (time-gain control) and preamp, subaperture beamformer, and digital control circuits for each transducer element all fit within the 0.019 mm2 area of the element. The transducer assembly was deployed in a 10 Fr (3.3 mm diameter) catheter, integrated with a GE Vivid1 E9 ultrasound imaging system, and evaluated in three pre-clinical studies...
