INTRODUCTION: Cardiac resynchronization devices are part of modern heart failure management. After implantation, we analyze and program devices in an attempt to ensure their success. Biventricular pacing should be 98% or more for the lowest mortality and best symptom improvement. CASE PRESENTATION: In this case series, we present a combination of far field sensing and automatic mode switching (AMS) in six patients. It is found that this combination causes ventricular sensing (VS) episodes with wide QRS and no synchronization...

BACKGROUND: Prolongation of the QT interval is considered a risk factor for cardiac adverse events and mortality. Left bundle branch block (LBBB) lengthens the QT interval. The corrected QT interval (QTc) is most likely overestimated because its prolongation is caused by increases in depolarization duration and not in repolarization. OBJECTIVES: In this study, we aimed to apply corrected JT interval (JTc) as an appropriate measure of ventricular repolarization for predicting QTc in a formula...

INTRODUCTION: In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. CASE PRESENTATION: The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest...

INTRODUCTION: Coronary vessel perforation is one of the most feared complications of coronary angioplasty. The treatment of this complication relies mostly on the implantation of covered stents. However, due to their design, covered stents are difficult to advance in a tortuous or calcified vessel. CASE PRESENTATION: We present a case of a grade III coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. CONCLUSIONS: The double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation...
