Summary

This study aims to learn more about heart and blood vessel diseases by observing people who have them or are at risk. Researchers will collect samples and perform tests like imaging and stress tests on up to 5,000 participants, including healthy volunteers and relatives of affected individuals. The goal is to improve diagnosis and understanding of these conditions, not to test a new treatment.

* INCLUSION CRITERIA: Eligible subjects may include anyone over 1 year of age who is affected with diseases/disorders (index cases), or who is a relative of a person who is affected with diseases/disorders. Relatives may include genetic carriers and non-carriers. * Healthy adult volunteers must be 18 years of age or older, and must agree to have blood or tissue samples studied, and potentially stored for future research. * Index cases enrolled in this protocol will have been referred with a known or suspected pathology that may be associated with cardiovascular dysfunction or risk with a suspected atypical presentation, heritable disorder, or genetic predisposition. The investigator with expertise in the presentation of the subject, along with consulting specialists, will review the medical history and may review any medical records that are available of prospective subjects and offer admission based upon the potential to help the individual, to learn from the subject, or to initiate clinical or basic research suggested by the subject s workup. EXCLUSION CRITERIA: * Persons of less than 1 year of age or greater than 100 years of age * Healthy volunteers unable to give informed consent or who decline to have blood and/or tissue studies, or who do not consent to have samples stored for future research may be excluded from this study. * Pregnant women * Persons who are not fluent in the English language will be excluded from Patient Reported Outcome Questionnaires. Such persons would be unable to properly complete questionnaires that are only valid in the English language.
