In conclusion, Marfan syndrome is associated with arrhythmias, particularly ventricular arrhythmias, due to structural abnormalities in the cardiovascular system resulting from fibrillin-1 mutations. The management of MS involves medical therapy to slow the progression of aortic dilation and decrease the risk of dissection, as well as the use of antihypertensive medications and antiarrhythmic drugs for life-threatening ventricular arrhythmias.
