We report on an atrial tachycardia (AT), emanating from the non-coronary (NC) aortic cusp, ablated with the aid of an electro-anatomical navigation system. In this setting, the electrocardiographic, electrophysiologic (EP), anatomical, and ablative considerations are discussed.Although NC aortic cusp focal ATs are an uncommon EP finding, their ablation is effective and safe, especially from an atrio-ventricular (AV) conductive point of view. This origin of AT must be invoked and systematically disclosed when a peri-AV nodal AT origin is suspected, in order to avoid a potentially harmful energy application at the vicinity of the AV conductive tissue.

Background: Transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with severe aortic valve stenosis; however, clinical valve thrombosis is a major challenge.
Case Summary: A 92-year-old woman underwent TAVR for severe aortic stenosis. One month later, the patient developed acute heart failure.

The patient an 85-year-old female resided in a care facility where she maintained an independent daily activity level. She was discovered hunched over a table in her room, displaying reduced responsiveness and prompting an emergency call. Initially, her blood pressure was within 60 mmHg, and she was transported by ambulance to our hospital.

A 63-year-old man was diagnosed with myelodysplastic syndrome (MDS) at the age of 62 by the hematology department. The patient underwent four cycles of azacitidine (AZA) therapy, followed by successful bone marrow transplantation (BMT). Subsequently, he was hospitalized twice for graft-versus-host disease (GVHD).

The autologous pericardial aortic valve repair technique developed by Ozaki et al., using glutaraldehyde-treated autologous pericardium, has demonstrated superior durability to bioprosthetic valves. However, this technique has certain limitations, including excessive cusp height and cusp fluttering due to leaflet redunduncy.

A 77-year-old man had severe aortic stenosis and continuous atrial fibrillation. We performed maze procedure without left atrial incision( Dallas lesion set) during aortic valve replacement for this patient. Dallas lesion set alternates the isolation of mitral isthmus by connecting ablation line beneath left coronary cusp and noncoronary cusp commissure of the aortic valve with ablation from epicardial side of the upper left atrium.
