Epidemiology is the study and analysis of the distribution, patterns and determinants of health and disease conditions in a defined population.
Constrictive pericarditis is a medical condition characterized by a thickened, fibrotic pericardium, limiting the heart's ability to function normally. In many cases, the condition continues to be difficult to diagnose and therefore benefits from a good understanding of the underlying cause.
Aortic valve replacement is a procedure whereby the failing aortic valve of a patient's heart is replaced with an artificial heart valve. The aortic valve may need to be replaced because:
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure in which a portion of the sympathetic nerve trunk in the thoracic region is destroyed. ETS is used to treat excessive sweating in certain parts of the body, facial blushing, Raynaud's disease and reflex sympathetic dystrophy. By far the most common complaint treated with ETS is sweaty palms. The intervention is controversial and illegal in some jurisdictions. Like any surgical procedure, it has risks; the endoscopic sympathetic block (ESB) procedure and those procedures that affect fewer nerves have lower risks.
Bariatrics is the branch of medicine that deals with the causes, prevention, and treatment of obesity.
John Heysham Gibbon was an American surgeon best known for inventing the heart–lung machine and performing subsequent open-heart surgeries which revolutionized heart surgery in the twentieth century. He was the son of Dr. John Heysham Gibbon Sr., and Marjorie Young Gibbon, and came from a long line of medical doctors including his father, grandfather Robert, great-grandfather John and great-great grandfather.
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, and summarizes interpretations into a refined conclusion. For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine.
Hemimegalencephaly (HME), or unilateral megalencephaly, is a rare congenital disorder affecting all or a part of a cerebral hemisphere. It causes severe seizures, which are often frequent and hard to control. A minority might have seizure control with medicines, but most will need removal or disconnection of the affected hemisphere as the best chance. Uncontrolled, they often cause progressive intellectual disability and brain damage and stop development.

He is also the National Co-Principal Investigator of the FDA pivotal trial of the Medtronic-CoreValve transcatheter aortic valve replacement device.
Elastofibroma dorsi is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers. The World Health Organization, 2020, has classified elastofibroma tumors as one specific type of the fibroblastic and myofibroblastic tumors.

Open aortic surgery (OAS), also known as open aortic repair (OAR), describes a technique whereby an abdominal, thoracic or retroperitoneal surgical incision is used to visualize and control the aorta for purposes of treatment, usually by the replacement of the affected segment with a prosthetic graft. OAS is used to treat aneurysms of the abdominal and thoracic aorta, aortic dissection, acute aortic syndrome, and aortic ruptures. Aortobifemoral bypass is also used to treat atherosclerotic disease of the abdominal aorta below the level of the renal arteries. In 2003, OAS was surpassed by endovascular aneurysm repair (EVAR) as the most common technique for repairing abdominal aortic aneurysms in the United States.
Medical Associates for Research and Communication (MARC) is a Non-Governmental Organisation that works globally with medical students and researchers with little to no background in research. Their primary goal is to help these researchers complete their research work using appropriate scientific methods thereby maintaining high scientific and research standards. Members of MARC were involved in a pilot study that later proved to be a landmark research study that formed the impetus for the creation of a 911 like system in India.
Cardioprotection includes all mechanisms and means that contribute to the preservation of the heart by reducing or even preventing myocardial damage. Cardioprotection encompasses several regimens that have shown to preserve function and viability of cardiac muscle cell tissue subjected to ischemic insult or reoxygenation. Cardioprotection includes strategies that are implemented before an ischemic event, during an ischemic event and after the event and during reperfusion. These strategies can be further stratified by performing the intervention locally or remotely, creating classes of conditioning known as remote ischemic PC (RIPC), remote ischemic PostC and remote ischemic PerC. Classical (local) preconditioning has an early phase with an immediate onset lasting 2–3 hours that protects against myocardial infarction. The early phase involves post-translational modification of preexisting proteins, brought about by the activation of G protein-coupled receptors as well as downstream MAPK's and PI3/Akt. These signaling events act on the ROS-generating mitochondria, activate PKCε and the Reperfusion Injury Salvage Kinase (RISK) pathway, preventing mitochondrial permeability transition pore (MTP) opening. The late phase with an onset of 12–24 hours that lasts 3–4 days and protects against both infarction and reversible postischemic contractile dysfunction, termed myocardial stunning. This phase involves the synthesis of new cardioprotective proteins stimulated by nitric oxide (NO), ROS and adenosine acting on kinases such as PKCε and Src, which in turn activate gene transcription and upregulation of late PC molecular players.
