  Coronary Angiogram Explained – Understanding Each Angiographic View Coronary angiography is the gold standard investigation to visualize coronary artery anatomy, detect stenosis, and guide interventional decisions. Correct interpretation depends on understanding standard angiographic views and knowing which coronary segments are best seen in each projection. Basic Coronary Anatomy Left Main Coronary Artery (LM) divides into the Left Anterior Descending (LAD) and Left Circumflex (LCX). LAD gives diagonal branches and septal perforators. LCX gives obtuse marginal branches. Right Coronary Artery (RCA) gives conus, SA nodal, acute marginal branches and usually the PDA. Left Coronary System Views LAO Caudal View (Spider View) Best for left main coronary artery, LM bifurcation, proximal LAD and proximal LCX. The LM resembles a spider body with LAD and LCX as legs. This is the most important view to assess left main disease and ostial LCX lesions. RAO Caudal View Best for LCX and obtuse...

Understanding the Rentrop Classification: A Guide to Coronary Collateral Circulation When a coronary artery becomes completely blocked, the heart doesn't always lose all blood supply to that area. Thanks to collateral circulation, smaller vessels can sometimes step in to provide alternate routes for blood flow. The Rentrop classification system helps cardiologists assess just how well these backup pathways are working during coronary angiography. What is the Rentrop Classification? Developed to standardize the assessment of coronary collateral vessels, the Rentrop classification grades collateral circulation on a scale from 0 to 3. This grading system is particularly important when evaluating patients with chronic total occlusions or severe coronary artery disease. The presence and quality of collateral circulation can significantly impact patient outcomes, treatment decisions, and prognosis. The Four Grades Explained Grade 0: No Visible Collaterals In Grade 0, there are no visible...

Coronary Artery Dilation: Three Essential Terms Every Cardiac Professional Should Know The cardiac catheterization laboratory, commonly known as the cath lab, is where some of the most critical diagnostic and therapeutic procedures in cardiology take place. Among the many findings that interventional cardiologists encounter, coronary artery dilations represent a unique and clinically significant category that requires precise terminology and careful assessment. Today, we'll explore three fundamental terms that every cardiac professional should understand: coronary artery aneurysm, coronary artery ectasia, and giant coronary aneurysm. Why Precise Terminology Matters in the Cath Lab In the high-stakes environment of interventional cardiology, precise communication can literally save lives. When discussing coronary artery abnormalities, using the correct terminology ensures that the entire healthcare team understands the exact nature, extent, and severity of the pathology. This clarit...

Attempt this exam to know your Score to get an idea of your fcps part 2 toacs preparation: Welcome to cardiology toacs mock exam , there will be 40 stations, time for each station is usually 3 mins in the exam but in this video it will be, 1 min. you can pause the video if you need more time.  Answer key is also shown in the video after 40 stations. For More TOACS stuff <<Click here>> In this comprehensive TOACS (Task Oriented Assessment of Clinical Skills) session, the candidate is taken through multiple diagnostic modalities in cardiology: surface ECG, chest-X-ray (CXR), echocardiography (Echo), cardiac catheterisation/angiography (Cath), cardiac CT, cardiac MRI (CMR), electrophysiology (EP) tracings, and nuclear scans (e.g., SPECT stress test). The aim is to test the ability of the trainee to interpret images/recordings, link them to the clinical scenario, derive diagnoses, and suggest appropriate next steps (management/investigations). The video shows multiple “stat...

  Healing Hearts, Restoring Rhythm: A Step-by-Step Guide to Percutaneous Transvenous Mitral Commissurotomy (PTMC) Keywords: PTMC, mitral stenosis, heart valve disease, minimally invasive procedure, interventional cardiology Introduction: Mitral stenosis, a narrowing of the mitral valve opening, affects millions worldwide, causing symptoms like shortness of breath, fatigue, and palpitations. Percutaneous Transvenous Mitral Commissurotomy (PTMC) is a minimally invasive procedure that offers a life-changing solution for these patients. In this article, we'll delve into the world of PTMC, explaining the step-by-step process and shedding light on this remarkable treatment option. What is PTMC? PTMC is a non-surgical procedure used to treat mitral stenosis. It involves using a balloon catheter to widen the narrowed mitral valve, restoring normal blood flow and alleviating symptoms. Step-by-Step Guide to PTMC: Step 1: Preparation Patients undergo thorough evaluation, including echocardiog...

Cardiac Cath Practice Cases with Answers:   Basic Views of Coronary Angiogram: Introduction: Coronary angiography is a crucial diagnostic tool used to assess the coronary arteries' health and detect blockages or abnormalities. This procedure involves injecting a contrast dye into the coronary arteries and capturing X-ray images to visualize blood flow and identify potential issues. Understanding the various angiogram views, structures visible, and troubleshooting techniques is essential for healthcare professionals involved in cardiac care. 1. Basic Coronary Angiogram Views:    - Right Anterior Oblique (RAO) View: Provides a clear visualization of the right coronary artery (RCA) and its branches.    - Left Anterior Oblique (LAO) View: Offers a detailed look at the left coronary artery (LCA) system, including the left main coronary artery (LMCA), left anterior descending artery (LAD), and left circumflex artery (LCx).    - Cranial/Caudal Views: These vi...
