You may create stereograms from two types of 3D data: AutoCAD DXF files, or range pictures in JPEG or BMP format.įor 3D data in DXF format, you may manipulate (e.g. Supported depth map and pattern image file types: PNG, TIFF, JPEG, BMP, GIF, PICT, etc.Oversampling to give smooth depth levels.Center to both sides method to minimize the distortion.Customizable dimensions (resolution, observer distance, maximum depth, and eye separation).Generate a "wall-eyed" (divergent) or "cross-eyed" (convergent) stereogram.Sirds lets you create Single Image Random Dot Stereogram (SIRDS) and Single Image Stereogram (SIS) images. Your stereogram will be generated automatically : “Treating Heart Attack with Angioplasty & Stenting.This program will allow you to create your own text-based 3D stereogram! The best part is that it is incredibly easy to use! Simply enter any word in the "Hidden Word" text field (such as your name) that you would like to make into a stereogram and click the GO! button. ![]() Journal of the American College of Cardiology: Cardiovascular Interventions: “Outcomes After Emergency Percutaneous Coronary Intervention in Patients With Unprotected Left Main Stem Occlusion: The BCIS National Audit of Percutaneous Coronary Intervention 6-Year Experience.” Texas Health Resources: “The ‘This Is Us’ Widowmaker Heart Attack Explained.”Ĭleveland Clinic: “How You Can Outsmart the Widow Maker Artery,” “Cardiac Catheterization & Coronary Angioplasty and Stent (Interventional Procedures).”Īmerican Heart Association: “What Is an Automatic External Defibrillator?” “Heart Disease and Stroke Statistics 2018 At-a-Glance.” Michigan Health: “A Doctor Explains What Makes a Heart Attack a ‘Widowmaker.’” National Cancer Institute: “Structure of the Heart.” Texas Heart Institute: “When speaking of heart disease, what is the Widowmaker?” If your doctors find blockages in three or more coronary arteries, you may need heart surgery. If the ER team unblocks your left main or LAD artery quickly enough, you could have little or no damage to your heart. This can be done during your angioplasty. To prevent that, doctors can also put in a small stainless steel mesh tube called a stent to prop open the artery walls. This is called an angioplasty.Īrteries opened with angioplasty can become blocked again. A tiny balloon at the tip of the catheter will inflate and push through the blockage. They’ll make a small cut through your skin, maybe in your leg or wrist. Instead, your doctors most likely will need to place one or more stents.įirst, your doctors will thread a thin tube called a catheter to reach the blocked artery. Restoring the blood flow can prevent scars on your heart that can do permanent damage. ![]() The ER team races against time to unblock your left main or LAD artery within 90 minutes of your heart attack. You may survive a widow maker if the emergency room doctors can treat you quickly. You’re more likely to have heart attacks if you: Cholesterol and fatty plaque clog your arteries over time and choke off blood. Heart attacks, including widow makers, usually happen because of a combination of lifestyle and genetic reasons. Paramedics can try to revive your heart immediately if it’s stopped. That’s almost always better than having someone drive you to the ER. Women report this more often than men do. This can happen with or without chest discomfort. You feel like you can’t catch your breath. You might feel it in one or both arms, your back, neck, jaw, or stomach The feeling might go away and then return You may feel pain, pressure, squeezing, or fullness in the center of your chest for several minutes. This is the most common symptom for women and men. You will have the same warning signs as you would with other types of heart attacks. If blood gets 100% blocked at that critical location, it may be fatal without emergency care. Without oxygen, the cells in your heart muscles start to die in minutes.Ī widow maker is when you get a big blockage at the beginning of the left main artery or the left anterior descending artery (LAD). When something cuts off the flow, you have a heart attack. ![]() Your heart muscle needs a constant supply of blood. Without emergency treatment, you may not survive.ĭespite its name, the widow maker strikes women, too. It can happen suddenly when a key artery that moves blood to the heart gets almost or completely blocked. Heart attacks can be deadly, and the widow maker is one of the deadliest kind. ![]()
