AtrendynurseInterventional radiology (IR) is a medical subspecialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound.
The transcatheter aortic valve replacement (TAVR) is an established treatment for patients with severe
symptomatic aortic stenosis (AS) at prohibitive risk for surgery. It is an alternative treatment to surgical
aortic valve replacement in patients with AS at intermediate- and high-surgical risk.
Inferior vena cava filter, or just IVC filter, is an endovascular device which is typically placed in the infrarenal inferior vena cava (IVC) to prevent pulmonary embolism in selected patients. This procedure is most often performed by interventional radiologists under fluoroscopic guidance.
The development of deep venous thrombosis (DVT) and pulmonary
embolism (PE) remains a daily concern for physicians who care for
critically ill patients. Diagnosing PE is challenging in the intensive care
unit (ICU) because signs and symptoms are nonspecific. In greater than
two-thirds of patients, acute PE occurs prior to the diagnosis of DVT.
A pacing system is defined as a medical device used for treatment of bradycardia or heart failure; it comprises the device itself and implanted leads.
ICDs are intended to provide ventricular anti-tachycardia pacing and ventricular de fibrillation shocks for automated treatment of life threatening ventricular arrhythmias.
It is an important therapeutic tool in the treatment of rheumatic mitral stenosis. It was first performed in 1984 as an alternative to surgical mitral valve commissurotomy. The majority of pulmonary mitral valvotomy procedures are performed in developing countries. It is skilled procedures and should be done only at centers which perform routine catheterization.
Coarctation of the aorta is a congenital heart disease that is associated with an increased morbidity and mortality even years after treatment. Percutaneous catheter interventions, including balloon dilatation and stenting, are frequently performed to treat the coarcted segment of the aorta.
Percutaneous balloon pulmonary valvulotomy (BPV) is preferred in moderate (gradient 40 to 60 mmHg) to severe (greater than 60 mmHg) pulmonary stenosis and it is the first-line treatment of typical dome-shaped valvular pulmonary stenosis in severe stenosis (gradient greater than 60 mmHg). BPV is also the preferred treatment in neonates with critical pulmonary stenosis.
Temporary cardiac pacing may become necessary as treatment or as prophylaxis of hemodynamic instability resulting from tachy- or bradyarrhythmia. The goal is to restore effective cardiac depolarization until the dysrhythmia either can be resolved or until a long-term therapy is initiated. The transcutaneous and transvenous approaches are most commonly used. Other modalities such as transesophageal […]
Pericardiocentesis is a procedure in which a syringe and needle are passed through the chest wall and into the pericardial space in order to aspirate fluid.
