In this case, review of OCT images after successful closure of a coronary perforation (CP) showed that the initial CP was visible as an abrupt interruption of the intimal tissue and the presence of a crater with blood reaching the external layers of vessel wall. CP was probably caused by overstretch of the vessel wall in an intramural segment of the left anterior descending coronary artery. CP is a possible complication of PTCA that is rarely documented with intracoronary imaging due to its rapid and dramatic evolution. We report the unique images of how an initial CP appears at OCT.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.

Background And Aims: When dealing with severely calcified lesions in endovascular therapy (EVT) for lower extremity artery disease (LEAD), navigating through severely calcified chronic total occlusion (CTO) using hard-tip guidewires can be challenging. To address this issue, we employed a novel highly intensive penetration (HIP) technique. This technique involves modifying the tail of a 0.

Cardiac tamponade is a rare but fatal complication of catheter ablation. We are reporting a case of a 73-year-old male with ventricular tachycardia (VT) storm undergoing urgent VT ablation, who was later found to have right ventricle (RV) perforation-an unusual site for catheter ablation complication. The patient underwent isochronal late activation mapping (ILAM)-based ablation and elimination of local abnormal ventricular activities (LAVA).

Introduction: Permanent implantation of a DF-4 implantable cardiac defibrillator (ICD) lead in the left bundle branch area (LBBA-ICD) is the next paradigm in amalgamating cardiac resynchronization therapy (CRT) and defibrillation. We systematically investigated feasibility/success rate, procedural caveats, and complications associated with a permanent DF-4 LBBA ICD implant and pertinent data at short-term follow-up.
Methods: We prospectively attempted implantation of 7 Fr Durata (Abbott, Chicago, IL, USA) single coil DF-4 ICD lead at the LBBA using a fixed-curve non-deflectable CPS locator delivery sheath.

Infective endocarditis (IE) is an infection that affects the heart valves, endocardium, and great vessels. It has a mortality rate of approximately 30% per year, so early diagnosis is essential to reduce morbidity and mortality. Cardiac angio-CT triggered by electrocardiogram (ECG) has been considered in IE management guidelines in recent years, given its high spatial resolution, contributing to the diagnosis and evaluation of valvular complications (vegetations, perforations, dysfunctions), perivalvular (abscesses, pseudoaneurysms, prosthesis dehiscence, fistulas) and compromised coronary arteries (embolism), allowing early diagnosis and treatment.
