Our concepts of heart disease are based on the enormous reservoir of physiologic and anatomic knowledge derived from the past 70 years' of experience in the cardiac catheterization laboratory.
As Andre Cournand remarked in his Nobel lecture of December 11, 1956, the cardiac catheter was the key in the lock.
By turning this key, Cournand and his colleagues led us into a new era in the understanding of normal and disordered cardiac function in huma
There are many interventional cardiac procedure those need a trans septal puncture of the interatrial septum. This presentation clearly elaborates everything you need to know about the TSP.
rotablation is procedure used in complex pci with heavily calcified lesion for adequate expansion of stent.if used in indicated case and well aware of contraindication is necessary for achieving good results.
Percutaneous Balloon Mitral Valvuloplasty (PBMV) is a procedure to dilated the mitral valve in the setting of rheumatic mitral valve stenosis. A catheter is inserted into the femoral vein, advanced to the right atrium and across the interatrial septum. Then the mitral valve is crossed with a balloon and it is inflated to relieve the fusion of the mitral valve commissures effectively acting to increase the mitral valve area and reduce the degree of mitral stenosis. Mitral regurgitation is a potential complication and thus PBMV is contraindicated if moderate or severe regurgitation is present. The Wilkins score examines mitral valve morphology and is determined via echocardiography to assess the likelihood of using PBMV based on certain echocardiographic criteria.

preop TEE assessment of atrial septal defect is very important for making decision for device closure, properly assessed adequate rims of ASD will reduce risk of device embolization to almost nil.
Devices and technology in interventional cardiologyRamachandra Barik
In the past 2 to 3 decades, the field of pediatric
interventional cardiology has experienced significant
growth. Technological innovations have greatly advanced treatment of cardiovascular disease in both children and adults with congenital heart disease (CHD). Interventional therapy has become an acceptable alternative treatment for many CHD, including closure of atrial defects,muscular ventricular septal defects (VSDs), patent ductus arteriosus (PDA), dilation of stenotic valves (aortic and pulmonary), and dilation of stenotic vessels (branch pulmonary arteries, coarctation of the aorta [COA]). In some cases where the percutaneous approach is difficult or the patient still
requires repair of other associated cardiac anomalies,
a hybrid approach can be implemented with its obvious advantages to the patient
Coronary CTO is characterized by heavy atherosclerotic plaque burden within the artery, resulting in complete (or nearly complete) occlusion of the vessel. Although the duration of the occlusion is difficult to determine on clinical grounds, a total occlusion must be present for at least 3 months to be considered a true CTO. Patients with CTO typically have collateralization of the distal vessel on coronary angiography, but these collaterals may not provide sufficient blood flow to the myocardial bed, resulting in ischemia and anginal symptoms. CTO is clinically distinct from acute coronary occlusion, which occurs in the setting of ST-segment–elevation myocardial infarction, or subacute coronary occlusion, discovered with delayed presentation after ST-segment–elevation myocardial infarction. Clinical features and treatment considerations of these entities differ considerably from CTO.
Among patients who have a clinical indication for coronary angiography, the incidence of CTO has been reported to be as high as 15% to 30%. Patients with CTO are referred for angiography because of anginal symptoms or significant ischemia on noninvasive ischemia testing. Patients who are symptomatic will have stable exertional angina resulting from a limitation of collateral vessel flow to meet myocardial oxygen demand with stress. Of patients referred for PCI in clinical trials of CTO PCI, only 10% to 15% of patients are asymptomatic. It is likewise uncommon for patients with CTO to present with an acute coronary syndrome caused by the CTO itself.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
