Catheter ablation of premature ventricular contractions (PVCs) arising from the left ventricular summit (LVS) presents technical challenges due to the regional anatomy and frequent intramural site of origin (SOO). Intracardiac echocardiography (ICE) and the CARTOSOUND® (Biosense Webster, Diamond Bar, CA, USA) module allow the operator to directly reconstruct and visualize the dimensions and orientation of the LVS live and present it in relation to neighboring structures. We retrospectively reviewed consecutive cases between January 2021 and December 2022 of patients undergoing PVC ablation for a presumed LVS origin...

BACKGROUND: Pulmonary vein isolation (PVI) alone is insufficient to treat many patients with persistent atrial fibrillation (PersAF). Adjunctive left atrial posterior wall (LAPW) ablation with thermal technologies has revealed lack of efficacy, perhaps limited by the difficulty in achieving lesion durability amid concerns of esophageal injury. OBJECTIVES: This study aims to compare the safety and effectiveness of PVI + LAPW ablation vs PVI in patients with PersAF using pulsed-field ablation (PFA)...

BACKGROUND: Primary cardiac tumors are uncommon, with the majority being benign myxomas. Cystic myxoma, a particularly rare type of benign cardiac tumor, demands cautious differential diagnosis from other cardiac tumors. CASE SUMMARY: A 43-year-old male patient presenting with intermittent dyspnea was referred to our department for surgical evaluation. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) unveiled an intra-left atrial cyst, which was subsequently found to be blood-filled during a video-assisted microinvasive heart surgery...

A 51-year-old patient with progressive right heart dysfunction was found to have a large calcified right atrial mass on echocardiography. As part of the work up for an intracardiac mass he had a cardiac computed tomogram which detailed a large coronary cameral fistula from the circumflex coronary artery to the right atrium associated with a spherical calcific pseudo-aneurysmal sac. Transcatheter occlusion of the exit point into the atrium with a vascular plug was performed directly from a right atrial approach without the need for an arteriovenous wire loop...

Heart masses, including tumors (primary and secondary) and pseudotumor (cysts and thrombus), are rare entities, but of increasing interest in cardiac imaging areas. The clinical manifestations are related to the intracardiac effect of mass, embolization, and systemic symptoms in the case of tumors; however, some of them are detected incidentally. Nowadays, imaging techniques and the advancement of their tools perform the morphological, functional, and tissue characterization of the masses, and additionally know the anatomical relationships, which are crucial factors for the treatment and surgical planning...

Left atrial appendage occlusion (LAAO) is an increasingly used alternative to oral anticoagulation in patients with atrial fibrillation, especially in patients with absolute/relative contraindications to these therapies. This review will cover three main aspects of the procedure. In the fist part of the manuscript, we focus on patient selection. We describe three main categories of patients with primary indication to LAAO, namely patients with previous or at a high risk of intracerebral bleeding, patients with a history of major gastrointestinal bleeding and patients with end-stage renal disease and absolute contraindication to novel oral anticoagulants...

OBJECTIVE: A quarter of all cardiac tumors are malignant, and most (~ 95%) are sarcomas. It is the most aggressive malignant cardiac tumor carrying the worst prognosis. Tumor involvement with the vital intracardiac structures makes it difficult for complete surgical resection. We aimed to study the role of complete surgical resection and its importance in long-term outcomes. METHODS: We analyzed published literature from 2002 to 2022 using PubMed. Cases reported adult, intracardiac sarcomas, and received surgical resections were included...

Automated recognition of heart shunts using saline contrast transthoracic echocardiography (SC-TTE) has the potential to transform clinical practice, enabling non-experts to assess heart shunt lesions. This study aims to develop a fully automated and scalable analysis pipeline for distinguishing heart shunts, utilizing a deep neural network-based framework. The pipeline consists of three steps: (1) chamber segmentation, (2) ultrasound microbubble localization, and (3) disease classification model establishment...

Paradoxical embolism occurs when a thrombus crosses an intracardiac defect into the systemic circulation. Here, we present the case of a 35-yearold male kidney transplant recipient with a cerebral paradoxical embolism associated with a spontaneous venous thromboembolism. This patient had recurrent deep venous thrombosis and showering emboli to the lung and paradoxically to the brain through patent foramen ovale, and we treated him successfully. The role of bubble echocardiography was essential in diagnosis to avoid contrast-induced nephropathy...

BACKGROUND: Failure of radiofrequency (RF) ablation of ventricular arrhythmias is often due to inadequate lesion size. Irrigated radiofrequency ablation with half-normal saline (HNS) has the potential to increase lesion size and reduce sodium delivery to the patient if the same volume of RF irrgant were used for NS and HNS, but could increase risks related to steam pops and lesion size. AIMS: To assess peri-procedural complications and acute ablation outcome of ventricular arrhythmias ablation with HNS...

A 68-year-old woman presented with an incidentally found intracardiac mass. Transesophageal echocardiography (TEE) showed a 26 × 8 mm mobile mass attached to a calcified posterolateral mitral annulus. The mass was removed with a commercially available percutaneous catheter system using cerebral embolic protection and TEE guidance. The pathologic examination showed caseous mitral annular calcification.

Infective endocarditis (IE) is a difficult-to-diagnose provocative disease that causes significant morbidity and mortality. The first-line imaging test for the diagnosis of IE is echocardiography. However, in cases of prosthetic IE or IE associated with intracardiac devices, its sensitivity is limited. A new diagnostic tool, 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT), improves diagnosis in these difficult cases. The most recent European guidelines for IE (2015) include this imaging modality as a primary diagnostic criterion...

Echocardiography is widely available in most cardiac centers, plays a key role in both the diagnosis and management of IE, is often the first-hand imaging modality, and should be performed immediately when mitral regurgitation is suspected. In addition, it is helpful during therapy and after surgery to assess valve morphology and function, complications, and heart function. In particular, transthoracic echocardiography is useful to detect new silent complications, monitor vegetation size, assess perivalvular abscess formation, pseudoaneurysm, intracardiac fistula and valvular perforation, as well as examine the embolic risk...
