Dr Giovanni Ferrari graduated from University of Pavia in Italy (2004). Following his Ph.D. he was appointed Research Scientist at New York University where he began a series of studies examining the mechanisms of aortic valve remodeling and calcification. He then joined the University of Pennsylvania faculty to develop the program of Cardiovascular Translational Research, with the vision of merging molecular and cellular biology with clinical science applied to cardiovascular diseases. Dr Ferrari is currently leading the Human Tissue Collection Program. He has been leading this UPENN program for more then 5 years. Dr Ferrari is the author of 50+ scientific publications; he has been awarded several grants from both Federal and Private scientific associations. He serves as a reviewer for some of the most prestigious scientific journal and association. He is a member of the American Heart Association and of the Society of Heart Valve Disease. He presented his research nationally and internationally and he holds two US patents for the diagnosis and treatments of valvular and vascular diseases.
Dr Ferrari's Lab supports a broad range of basic and translational science research projects in order to improve diagnosis, treatment, and prevention of cardiovascular disease.

Current Research Projects:
1) Aortic Valve Stenosis: Recent studies demonstrate that the even in the absence of clinical symptoms the thickening of the aortic valve leaflets is a pathological condition predisposing to several cardiovascular disease including chronic heart failure (CHF), myocardial infarction (MI) and, most prevalently, severe calcific aortic valve stenosis. Due to its asymptomatic presentation and to the fact that these valve are not replaced until symptoms occurs, little is known about the mechanisms of pathological remodeling.
We aim to characterize the molecular mechanism leading to aortic valve remodeling from physiological to pathological condition. Our projects on aortic valve disease integrate a highly complex phenomenon to develop a rational basis for future therapeutic strategies targeting subclinical aortic disease. Secondary to this, we are investigating cellular and molecular targets that can help the risk-stratification of patients to identify “fast” and “slow” progressors, and therefore understand why only a subgroup of patients with develop symptomatic aortic stenosis.
2) Cellular Physiology of Myxomatous Mitral Valve Prolapse: Heart valve disease at this time can only be treated surgically; no mechanism-based therapeutic strategies exist. The prolapse of the Mitral Valve (MV) leaflet is a hallmark of several disorders affecting this cardiac valve, such as myxomatous mitral valve disease (MMVD) or the pseudo-prolapse in chronic ischemic mitral regurgitation (MR). The overall goal of these studies is to identify therapeutic candidates for treating MMVD. The line of research could have major application in the diagnostic and clinical management of MV patients. First, our genetic data could be applied, in conjunction with imaging analysis, to risk-stratify Mitral Valve patients for the likelihood of developing early valvular disease. Second, our investigations could be applied to type of surgical intervention (repair vs. replacement); Most importantly, the results of this grant may generate important data on the pharmacological treatment of patients developing MMVD.
3) Molecular Determinants of Thoracic Aortic Aneurysm in Bicuspid and Trileaflets Aortic Valve: It is estimated that about one in 50 people are born with a bicuspid aortic valve (BAV). In the United States, a child is born with BAV every seven minutes, making BAV the most common congenital heart defect in the country. A bicuspid aortic valve is an aortic valve with only two leaflets instead of three. Patients with this congenital heart defect are at higher risk of developing calcification of the aortic valve, a condition requiring surgical intervention. Current clinical and scientific studies are also revealing that bicuspid aortic disease is not a simple valve condition, but it affects the aorta as well. A dissection or rupture of the aorta is a catastrophic event, with extremely high mortality. Our laboratory has recently developed a method to test the progression of BAV-associated aortopathies. In addition, we are characterizing the molecular and cellular mechanisms responsible for the weakening of the aortic wall in both BAV and tricuspid aortic valve (TAV) patients. This research has an important outcome for public health: it will provide physicians and scientists a tool to identify a patient population at high risk of valvular and vascular pathologies. Low risk patients could be spared costly follow-up or surgical intervention, while high-risk patients could be followed intensively both clinically and surgically. In addition, it provides new mechanistic insights into the development of cardiovascular diseases in this prevalent population.
