Six-Center Study of Chronic Atrial Fibrillation Indicates Importance of ...
/PRNewswire/ --nContact, Inc. (nContact), the leading minimally invasive epicardial ablation device manufacturer, reports with interest an article published in the European Journal of Cardio-thoracic Surgery that demonstrates the importance of a comprehensive epicardial lesion pattern combined with diagnostics to confirm conduction block in radiofrequency ablation for the successful treatment of persistent and long standing persistent atrial fibrillation (AF).
AF is the most common cardiac arrhythmia (abnormal heartbeat), affecting an estimated 5 million Americans and millions more worldwide. The study focused on persistent and longstanding persistent AF patients who have historically been the most challenging populations to treat because the condition is typically associated with structural heart disease, resulting in enlarged atria. The article discusses potential required elements to bring viable treatment options to this patient population.
Treating chronic AF using existing surgical and catheter approaches often does not assure complete isolation or interruption of reentrant conduction pathways, and as well, can produce limited long term outcomes. As described in the article, the use of nContact's guided coagulation system which produces long, linear lesions epicardially on a beating heart that may be connected into a complete, comprehensive, bi-atrial pattern based on the cut and sew Maze pattern, and can yield meaningful long term results.
The article discusses the importance of improving procedural effectiveness in treating AF by utilizing a comprehensive, bi-atrial lesion pattern and confirming conduction block. The ability to perform epicardial ablation on a beating heart enables the evaluation of conduction block during lesion creation.
Prof. Dr. , stated, "The confirmation of exit block at 15mA improves procedural effectiveness in treating AF. Performing epicardial ablation on a beating heart avoids cardiopulmonary bypass and aortic cross clamping associated with traditional procedures such as the cut and sew Maze, and allows for confirmation of conduction block." Since the heart remains electrically functional during the procedure, metrics may be evaluated intra-operatively to allow creation of additional lesions when block testing identifies a gap.
The article concludes that patients in whom exit block was confirmed at 15mA were statistically more likely to have successful clinical outcomes. Results indicate that at 12 months, 87% of patients with exit block confirmed were in sinus rhythm compared with 57% patients in which exit block was not tested. In addition, the creation of a comprehensive bi-atrial lesion pattern resulted in an increase in left ventricular ejection fraction and a reduction in left atrial size.

ablation for the successful treatment of persistent and long standing persistent atrial fibrillation (AF). AF is the most common cardiac arrhythmia (abnormal heartbeat), affecting an estimated 5 million Americans and millions more worldwide.
the team from Germany, France and the United States worked on reducing the energy required for defibrillation, a treatment that delivers a therapeutic dose of electrical energy to the heart for patients with cardiac arrhythmia.
In the case of other arrhythmias such as ventricular tachycardia and ventricular fibrillation, lack of treatment can prove fatal. Earlier, medication was the only mode of treatment for arrhythmia. Now, cardiac medicine has an array of treatment
Performing the first case, Dr. Andrea Natale, Executive Medical Director of Texas Cardiovascular Arrhythmia Institute at St. David's Medical Center, and a leading researcher in this area said, " The THERMOCOOL(R) SMARTTOUCH(TM) Catheter is a

Arrhythmia – Symptoms, Causes, Treatment
What is Arrhythmia?
Cardiac arrhythmia is a collective term for a group of changes and conditions in which the heart’s electrical impulses deviates from its normal sequence. The electrical sequence may happen to be fast or slow or maybe at some point erratic. This causes the heart to pump according to the changes in the impulse. When this happens, the heart cannot pump blood to the body thoroughly causing damage to the organs and even life-threatening medical emergencies which, if not properly addressed, can cause cardiac arrest or worst, death.
A sinus arrhythmia is refered to the normal electrical impulse wherein there is a mild acceleration of the heart rate and the heart beat is at 50-100 beats per minute. Arrhythmias as also called as dysryhtmias and it can happen even with a normal heart rate. There are many types of cardiac dysrytmias but to understand that better, it is important to know how the heart structures, how the blood is pump the heart and the electrical impulses that keeps the heart from beating. Thus, the different types of arrhythmia include:
Premature atrial contractions Premature ventricular contractions Atrial fibrillation Atrial flutter Paroxysmal supraventricular tachycardia Accessory pathway tachycardia AV nodal reentrant tachycardia Ventricular tachycardia Ventricular fibrillationSinus node dysfunction Heart blockThese arrhythmias seem complicated that is why it is very important to consult the doctor to have a thorough understanding. Cardiac arrhythmia’s prevalence tends to be higher as the person ages. Although it is normal for a heat to beat fast during exercise or any physical activity or when a person is stressed or excited, it should slow down when a person is sleeping or is at rest. Other than that, arrhythmia can occur and sometimes, sudden heart attack or cardiac arrest occurs. According to reports, there are about 250,000 cases of medical emergencies related to cardiac arrest in the United States that happen each year. and it continues to grow since others have simple disregard for an aching heart.
Arrhythmia SymptomsSometimes, anybody can feel a skipped beat or a fast heart rate. What is important is that they should not panic. Instead, they should rest and try to relax.
