As the prevalence of leadless pacemaker systems increases, identifying various methodologies for retrieval of these devices in certain instances becomes even more paramount. We describe a case demonstrating the utility of a coronary guide catheter as part of an improvised sheath-in-sheath technique for the challenging retrieval of a Micra™ leadless pacing system (Medtronic, Minneapolis, MN, USA).

Background: The role of Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) is still unclear in patients with STEMI undergoing PCI in the current second-generation DES era.
Aims: This study aimed to evaluate the trends and outcomes of IVUS-guided PCI in patients with STEMI.
Methods: We used the National Inpatient Sample (NIS) database from 2016 to 2021.

Background: This is a case report of a patient with Fabry disease (FD). We successfully treated a patient with ventricular septal hypertrophy and left ventricular outflow tract (LVOT) obstruction caused by FD. We report our exclusive new surgery for patients with LVOT obstruction, percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) procedure™ (percutaneous intramyocardial septal radiofrequency ablation).

There are currently several risk stratification scores available, which have largely been validated in various pulmonary hypertension registries in the West but not in Asia. We aim to study the performance of these different risk scores in PAH patients from a multi-ethnic Asian population.

The mechanism and severity of mitral valve (MV) regurgitation (MR) play a critical role in guiding treatment decisions. Transthoracic echocardiography (TTE) is the primary diagnostic modality for evaluating MV disease. Discordant findings on TTE can be further quantified through transesophageal echocardiography (TEE).

Background: Extubation of the coronary guiding catheter may affect flow and pressure measurements in the coronary vessel during invasive coronary angiography (ICA).
Aim: This study aims to investigate the impact of guiding catheter extubation on fractional flow reserve (FFR), coronary flow reserve (CFR), and the index of microcirculatory resistance (IMR).
Methods: This predefined subgroup analysis of the Dan-NICAD 2 study included patients with chronic coronary syndrome referred to ICA based on a coronary computed tomography angiography.
