Abstract
Mitral regurgitation (MR) is the most commonly found valvular lesion in echocardiography laboratories. Moderate and severe mitral regurgitation have proven to be associated with increased morbidity and mortality, and surgical reconstruction is recommended in severe cases whenever feasible. Three-dimensional echocardiography (3DE) is superior to conventional echocardiography in the…

Atrial Fibrillation
Atrial fibrillation (AF), the chaotic and disorganized activity of the upper chambers of the heart, is the most common cardiac rhythm disturbance. It affects approximately 1% of the US population, or almost three million people. It occurs more frequently in the aged, affecting about 5% of people over 70 and as many as 10% of people over the age of 80. AF is also considered to…

A number of mechanisms underlie the different forms of atrial fibrillation (AF). Pulmonary vein (PV) ectopy may act as a driver maintaining AF or as a trigger in which spontaneous PV firing may initiate episodes of AF. Non-pulmonary triggers also exist. In addition, multiple wavelet re-entry and rotors may maintain AF.
While pulmonary vein isolation (PVI) is central to most AF ablation…

Catheter ablation is the mainstay of treatment in the management of cardiac arrhythmias. The number of catheter ablation procedures performed worldwide in the past 25 years has significantly increased and is expected to increase further. Cardiac ablation requires catheters to be advanced and manipulated within cardiovascular structures. This manipulation has traditionally been performed under…

More than three-quarters of a million Americans will suffer a stroke this year. Stroke ranks as the third most common cause of death after heart disease and cancer. It is the number one cause of disability among adults and the main reason for rehabilitation. Many, but not all, strokes are related to atherosclerosisÔÇöthe same disease that causes heart attacks. Blockage of one of the two main…

In the US, 90% of the one million annual hospitalizations for heart failure (HF) are due to volume overload.1,2 Hypervolemia contributes to HF progression and mortality. Guidelines recommend that therapy for HF patients be aimed at achieving euvolemia. Intravenous loop diuretics induce rapid diuresis that reduces lung congestion and dyspnea. However, the effectiveness of loop diuretics declines…

Atrial fibrillation (AF) is a supraventricular arrhythmia characterized by poorly coordinated atrial activation and associated with reduced atrial mechanical function. Over the long term, it is associated with an increased risk of stroke, heart failure and mortality. AF can occur in the absence of overt structural heart disease in up to 30% of patients; however, hypertension, coronary artery…
