Arrhythmogenic correct ventricular cardiomyopathy ( ARVC ) is an heritable disorder that causes replacement of the ventricular myocardium with fibrofatty tissue that is more predisposed to the development of arrhythmias . This mainly hap in the leftover heart ventricle sub - endocardial muscle . It is a genetic disease inherited in an autosomal rife style with varying penetrance . These genetic mutation touch off inflammation of the myocardial cells and destroy desmosomal protein .
Clinical and Pathologic Features of Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
The fibrous and fatty tissue that occupy the ventricles is extremely arrhythmogenic and thus patients are at jeopardy of ventricular tachycardia that evolves into left bundle subdivision blocking . The disease may slowly progress leading to a demonstration withheart failuresymptoms such astachycardia , difficulty in breathing and generalised edema . It may also progress rapidly to presents as a sudden cardiac dying .
Arrhythmogenic Right Ventricular Cardiomyopathy Treatment Guidelines
Current interventional scheme are largely of palliative intent as curative strategy postulate reversal / replacement of the genetic mutant and the sequent desmosomal change which is impossible with the usable technology . The most crucial goal of therapy thus will include morbidness and mortality control , control of core bankruptcy symptoms that ameliorate the calibre of life of the patient and running capacity of the philia .
These goal can be achieved via the following modality :
Lifestyle Modification
This is the first line method of management of ARVC since the disease is associated with strenuous exercises . free-enterprise exercises are thus avoided in patients with a family history of the disease and any other history that may suggest other happening of the disease . It is effective as long as the patient is asymptomatic and can be used at the same time with other method of management in advanced cases of the disease .
Exercises promote dilatation and dysfunction of the centre chambers aggravate the functions of the diseased heart .
Pharmacological Treatment
It is the 2d blood therapy for the disease and mean medicinal drug in various groups most significant being anti - jerky drug such as amiodarone that function to control ventricular tachycardia and other abnormal rhythms that may arise .
Other drugs include β - blocking agent agents that have an anti - arrhythmic prop as they reduce the end diastolic filling time and regulate the charge per unit of the bosom . They are most significant in the event of an unanticipated exercise that may actuate sudden cardiac death .
tenderness failure drugs are used to control symptoms and include preload reducing drugs such as diuretic drug that prevent further left ventricular enlargement and anti - thrombogenic therapy .
Invasive Treatment
This is the method acting of selection for patients whose arrhythmias are refractory to pharmacological intervention . Catheter cutting out using endocardial catheter with radiofrequency currents has been used with some effectiveness .
Implantable cardioverter - defibrillator devices ( ICD ) are superscript implants that are inserted in mortal with a chronicle of cardiac arrest , a kinsfolk history of sudden cardiac end or refractory arrhythmias . The machine disrupt deadly ventricular cardiac arrhythmia by cardioversion .
warmheartedness transplantation is the last resort after drugs and implantable devices have failed . It is indicated for patients with uncontrollable heart failure symptoms especially if of a young long time .
Conclusion:
In summary , arrhythmogenic right ventricular cardiomyopathy ( ARVC ) is an inheritable disease which has no cure . It may present with feature of heart failure after easy progressing for years or as sudden cardiac end . morbidness and death rate of the disease is secondary to arrhythmias , left bundle branch blocks and sum failure all which occur in the scene of failing treatment . therapeutical interventions to control the progression are of alleviative intent and range from modus vivendi qualifying for symptomless disease , pharmacological therapy for modest disease , gimmick therapy for moderate disease and heart transplant for intractable disease .
