Balloon Angioplasty of Chronic Total Occlusion of the Coronary Sinus due to Lead Maturation Process-Juniper Publishers

Journal of Cardiology & Cardiovascular Therapy-Juniper Publishers

Massive rise of the pacing threshold during lead maturation period (up to 6 months post-implant) has declined after the introduction of steroid eluting electrodes but not totally disappeared [1], many trials discussed the management of this problem including systemic steroid therapy during the early stage but repositioning of the lead implantation of new lead remains the solution of the exit block. We describe a case of loss of capture of coronary sinus (CS) lead 3 months post-implant due to exit block which is thought to be due to lead maturation process resulted in extensive fibrosis inside the CS which was successfully managed by balloon angioplasty, followed by successful placement of new CS lead.

Physical Condition for the Coronary Artery Disease Patients-Juniper Publishers

Image
JUNIPER PUBLISHERS-OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Keywords: Aerobic exercise; Cardiac output; Maximal oxygen uptake Coronary Artery Disease Considerations A systematic review estimated that inactivity is responsible for 6% of the burden of disease from coronary heart disease worldwide [1]. CAD influence on work capacity and physical performance has been widely investigated. Myocardial functional changes include declines in maximum heart rate, stroke volume, left ventricular contractility and an increase in peripheral vascular resistance. Oxygen demand and supply for the Myocardium are normally balanced. Oxygen demand above quiescent needs of the Myocardium is determined by number of factors: Heart rate-the greater the frequency of contractions, the greater the oxygen demand. Myocardial wall tension is a function of both left ventricular systolic pressure and the ventricular radius [2]. The contractility of the heart-relates to the ...

Undetected pulmonary Artery Aneurysms Secondary to Prolonged Right-sided Endocarditis in a Patient with Corrected Tetralogy of Fallot-Juniper Publishers

Image
JUNIPER PUBLISHERS-OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Abstract Mycotic pulmonary artery aneurysms are a rare complication of right-sided endocarditis most often associated with congenital heart disease or intravenous drug addiction. We report a case of undetected mycotic pulmonary artery aneurysms secondary to prolonged right-sided endocarditis in a 25-years old patient with corrected tetralogy of Fallot /pulmonary atresia. An attempt to explain the delayed diagnosis of endocarditis with subsequent mycotic aneurysms formation is made and the clinical and imaging findings of this rare complication during a long-term follow up are presented, contributing to our knowledge on the natural history of this disease. Keywords: Mycotic aneurysms; Tetralogy of Fallot /pulmonary atresia; Right heart endocarditis; Kocuria varians Abbreviations: CT: Computed Tomography; TTE: Trans Thoracic Echocardiogram; MRI: Magnetic Resonance Imaging; MRA: Magne...
