Intracardiac echocardiography (ICE) is considered an alternative imaging modality for left atrium appendage occlusion (LAAO) to avoid general anesthesia. However, the quality of ICE images obtained from right atrium can be suboptimal compared with transesophageal echocardiography (TEE) imaging. Although placing an ICE probe into left atrium can improve imaging quality, there are limited data regarding procedure outcomes of ICE-guided LAAO versus TEE-guided LAAO. One hundred forty four patients who underwent LAAO with Amplatzer Cardiac Plug, Amulet, or Watchman device were enrolled from two referral institutes...

This paper reports an improved CMOS compatible low temperature sacrificial layer fabrication process for Capacitive Micromachined Ultrasonic Transducers (CMUTs). The process adds the fabrication step of silicon oxide evaporation which is followed by a lift-off step to define the membrane support area without a need for an extra mask. This simple addition improves reliability by reducing the electric field between the top and bottom electrodes everywhere except the moving membrane without affecting the vacuum gap thickness...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

OBJECTIVES: This study determined the relationship between the timing of left ventricular (LV) electrical activation and peak contraction at potential LV pacing locations in candidates for cardiac resynchronization therapy (CRT). BACKGROUND: Targeting the LV lead to the region of latest electrical activation or the segment of latest peak contraction has both been shown to improve CRT response. Whether these regions correspond within CRT patients is uncertain. METHODS: Twenty-eight consecutive CRT candidates underwent intraprocedural coronary venous electroanatomic mapping using EnSite NavX...

We present the case of a 17-year-old girl with Ebstein anomaly and repeated episodes of reentrant tachycardia due to a right posterior accessory pathway. Catheter ablation was performed using intracardiac echocardiography. A ViewFlex Xtra probe was inserted and showed an anormal tricuspid valve with elongated anterior leaflet and low insertion of the septal leaflet towards the apex. The anatomical annulus was identified by the course of the right coronary artery. RF application on the posterior annulus stopped the reentrant arrhythmia...

Aims: Due to the complex anatomy of the left ventricular (LV) and right ventricular (RV) papillary muscles (PMs), PM ventricular arrhythmias (VAs) can be challenging to target with ablation. We sought to compare the outcomes of robotic magnetic navigation-guided (RMN) ablation and manual ablation of VAs arising from the LV and RV PMs. Methods and results: We evaluated 35 consecutive patients (mean age 65 ± 12 years, 69% male) who underwent catheter ablation of 38 VAs originating from the LV and RV PMs as confirmed by intracardiac echocardiography...

Background: The utility of standard distal bipolar electrograms (sEGMs) for assessing catheter-tissue contact may be obscured by the presence of far-field signals. Microelectrode electrograms (mEGMs) may overcome this limitation. Methods: We compared 5 mEGM characteristics (amplitude, frequency content, temporal signal variability, presence of injury current, and amplitude differential between bipoles) with the sEGM for determining tissue contact in 20 patients undergoing ablation of typical atrial flutter...

Intravenous leiomyomatosis (IVL) is a condition in which leiomyoma originating from uterine myoma or intrauterine venous walls develops intravenously. A single-stage operation was planned by the departments of gynecology and cardiovascular surgery for a patient in which the IVL was extended across the tricuspid valve. It was possible to safely perform perioperative care with continued evaluation of the tumor position and intravascular volume through the use of transesophageal echocardiography (TEE). TEE can be useful in the intraoperative care of patients with intracardiac tumor extension as in this case...

Cardiac metastases from oral squamous cell carcinoma (SCC) are rare, especially in the absence of systemic metastasis. We describe a case of a patient presenting with chest pain and ECG abnormalities concerning for ST-elevation myocardial infarction that eventually was found to have an incidental right ventricular mass on chest CT angiogram. Ultimately, she had an intracardiac echocardiography-assisted biopsy diagnosis of isolated cardiac metastasis from primary oral SCC. The extent of the disease precluded any surgical intervention, and the patient subsequently transitioned to hospice care...

The acquisition of good contact force for radiofrequency catheter ablation of ventricular premature complexes (VPCs) originating from the basal septum of the left ventricle (LV) is often difficult. We describe a case of VPCs originating from the basal septum of the LV, which were successfully eliminated by applying radiofrequency at the right atrium (RA) side of the atrioventricular septum (AVS) without causing any significant impairment of atrioventricular conduction because the ablation catheter could obtain better contact force through the RA approach...

BACKGROUND: Patients undergoing cardiac surgery need extensive and invasive monitoring, which needs to be individually adapted for each patient and requires a diligent risk-benefit analysis. The use of a pulmonary artery catheter (PAC) seems to be justifiable in certain cases; therefore, the preoperative diagnosis of pulmonary hypertension represents an indication for perioperative monitoring with PAC in the S3 guidelines of the German Society for Anesthesiology and Intensive Care Medicine (DGAI)...

Cardiac angiosarcomas are extremely rare in childhood, they are rapidly progressive tumours that often present themselves as diagnostic dilemmas, resulting in delayed diagnosis. Also, extracardiac manifestations, including abdominal pain, are extremely rare in patients with intracardiac tumors. We herein present the case of a 15-year-old girl who presented with abdominal pain. Echocardiography and thoracic computed tomography showed right atrial mass. The patient underwent surgery, chemotherapy, and radiotherapy...

Lung cancers may extend along or grow through the pulmonary veins to invade or lie within the left atrium (LA). A 62-year-old man, previously healthy, presented with 1-month ventilatory-independent right hemithorax back pain, dry cough and large effort dyspnea. He also referred weight loss of 12 kg in 10 months and denied hemoptysis. As antecedents, he smoked for 40 years and moderate daily alcoholism. On physical examination, the patient was in good general condition, hydrated and regular respiration at rest [blood pressure (BP) =120/80 mmHg; heart rate (HR) =90 bpm; respiratory rate (RR) =16 rpm]...

Some manufacturers do not provide automated intracardiac electrogram method (IEGM) systems for atrioventricular (AV) and interventricular (VV) delay optimization in cardiac resynchronization therapy (CRT). We aimed to evaluate the accuracy of manual IEGM method in 48 patients previously implanted with Medtronic Syncra CRT. All patients underwent standard device interrogation followed by CRT optimization by IEGM method and by echocardiography one month after implantation. The patient mean age was 60.7±11.8 years and there were 33 (68...

Inferior vena cava (IVC) filters are increasingly used in patients with recurrent venous thromboembolism in whom anticoagulation is contraindicated or intolerable. Migration of fragments is a known complication of IVC filter use. We present a case of a 32-year-old man, who presented with right-sided chest pain believed to be caused by a migrated IVC fragment to the right ventricle. The filter was removed by an endovascular cook forceps with the assistance of intracardiac echocardiography. This case serves as an addition to the existing reports of successful removal of intracardiac fragments via minimally invasive endovascular approach, amid a larger number of intracardiac fragments that have been removed by an open-heart approach...
