MRCP ROAD - PACES

The problem was not simply a thrombus inside a coronary artery. The problem was: The wall of the aorta itself was dissecting. Giving thrombolysis in this situation could cause catastrophic bleeding, worsen haemorrhage or precipitate cardiac tamponade, turning a critical surgical emergency into a disaster. This patient needed: Immediate cardiothoracic surgical involvement Not blind thrombolysis. ⸻ 🎬 Scene 8 — The Teaching Round Later, the consultant asked the residents: “What would be wrong if I told you the diagnosis was myocardial infarction?” One of them replied: “But he actually did have an MI.” The consultant smiled. “Exactly.” Then he wrote on the board: A correct diagnosis is not always the complete diagnosis. He continued: “The problem is not always that you made the wrong diagnosis.” “Sometimes the problem is that you found a correct diagnosis too early…” “…and stopped looking for the cause.” Then he wrote: Aortic Dissection ↓ Coronary Involvement ↓ Acute Myocardial Infarction ↓ Cardiogenic Shock He circled the first line. “If you treat only the end of the chain…” “You may kill the patient because you never saw where the chain began.” ⸻ ☀️ When Should You Think of Aortic Dissection? Especially when acute chest pain is accompanied by one or more of the following: ☀️ Abrupt onset / pain maximal at onset ☀️ Pain radiating to the back ☀️ Pulse deficit or blood pressure differential ☀️ New aortic regurgitation murmur ☀️ Neurological deficit ☀️ Syncope ☀️ Unexplained shock ☀️ Features of cardiac tamponade ☀️ Acute coronary syndrome with features that simply don’t fit ⸻ ☀️ Lessons Learned ☑ Do not automatically assume that shock + chest pain = massive PE. ☑ Do not allow ST-segment or ischaemic ECG changes to automatically close your thinking at myocardial infarction. ☑ Ask about the onset and character of the pain. Ten seconds of history can completely change the treatment. ☑ Check peripheral pulses and blood pressure in both arms when feasible and when doing so does not delay resuscitation. ☑ Use bedside echocardiography as part of the rapid assessment of an unstable patient, while remembering that the absence of obvious echocardiographic findings does not exclude aortic dissection. ☑ Stanford Type A aortic dissection is a surgical emergency. ☑ Suspected aortic dissection completely changes the decision regarding antithrombotic and thrombolytic therapy. ⸻ 🎯 Final Message The most dangerous diagnosis in the Emergency Department… is not always the diagnosis you failed to consider. Sometimes it is the diagnosis for which you found convincing evidence… and then stopped thinking. He had a myocardial infarction. He was in cardiogenic shock. Both were true. But the most important truth was hiding one step further back: Aortic Dissection So when the clinical picture does not completely fit… don’t ask only: “What is happening?” Also ask: “What caused it to happen?” Because the first answer may tell you what is happening to your patient… but the second may be the answer that saves their life.

🩺 A Medical Story 🎬 Scene 1 — He Was Sitting With His Family A man in his early sixties. Just minutes earlier, he had been completely well. He was sitting with his family, talking and laughing as usual. Then suddenly… He grabbed his chest. “My chest…!” The pain was severe and came out of nowhere. Within seconds, he became extremely short of breath. He tried to stand up… but collapsed back into his chair. His face became pale. His body was drenched in sweat. His hands and feet became ice-cold. He was rushed to the Emergency Department. ⸻ 🎬 Scene 2 — He Was Crashing On arrival: 🔴 Severe chest pain 🔴 Severe dyspnoea 🔴 Profuse sweating 🔴 Cold peripheries 🔴 Altered mental status 🔴 BP barely recordable 🔴 Severe haemodynamic instability The patient was clearly in shock. One of the doctors said: “Sudden chest pain + severe dyspnoea + shock…” Then added: “This could be a massive PE.” The patient was deteriorating in front of them. There was no time for a ten-minute history. But sometimes… three questions are more valuable than ten investigations. ⸻ 🎬 Scene 3 — The Question That Changed Everything While the team continued resuscitation, the doctor leaned toward the patient. “Did the pain start gradually or suddenly?” The patient struggled to answer: “Suddenly…” “All at once…” The doctor asked: “Was it at its worst from the very beginning?” He nodded. “Yes…” Then came the most important sentence: “I can feel it going through to my back.” The doctor paused. Sudden severe chest pain — maximal at onset — radiating to the back. That was not a minor detail. That was a red flag. ⸻ 🎬 Scene 4 — But the ECG Made Things Even More Complicated A 12-lead ECG was performed immediately. The team stared at the tracing. There were: Acute ischaemic ECG changes. 🔴 One of the doctors said: “That’s it… Acute coronary syndrome.” Now they had another very convincing diagnosis. Chest pain. Shock. Sweating. Ischaemic ECG changes. Everything seemed to point towards an acute myocardial infarction. But the doctor went back to the patient. Something still bothered him. “Why was the pain maximal from the very first second?” “And why is it radiating to his back?” He refused to let the ECG erase the history. ⸻ 🎬 Scene 5 — An Examination That Took Seconds The doctor checked the pulse in the right arm. Then the left. He stopped. And checked again. The peripheral pulses were unequal. He then checked the blood pressure in the other arm. There was a significant difference. The atmosphere in the room changed. The doctor said: “Wait…” “The ECG may be showing us the complication… not the original problem.” ⸻ 🎬 Scene 6 — The Missing Piece A focused bedside echocardiogram was performed while resuscitation continued. The findings raised even more concern for an acute aortic syndrome. This was no longer simply a patient with chest pain and shock. The question had changed to: Could this be an Acute Aortic Dissection? Because of his severe haemodynamic instability, definitive imaging and specialist assessment were urgently expedited. Then the truth appeared. 🔴 Stanford Type A Aortic Dissection The dissection had extended to involve a coronary ostium. This caused: Coronary malperfusion ↓ Acute myocardial infarction ↓ Severe LV dysfunction ↓ Cardiogenic shock For a moment, the room went silent. The ECG had not been wrong. The patient really did have a myocardial infarction. But the myocardial infarction was not the complete diagnosis. It was the consequence of something far more dangerous. ⸻ 🎬 Scene 7 — The Decision That Could Have Changed the Ending The consultant looked at the team and said: “Imagine if we had stopped at the ECG.” Then he pointed towards the screen. “And imagine if we had given thrombolytic therapy before thinking any further.”

خصوصًا عندما تجد acute chest pain مع واحد أو أكثر من: ☀️ Abrupt onset / maximal pain at onset ☀️ Pain radiating to the back ☀️ Pulse deficit or BP differential ☀️ New aortic regurgitation murmur ☀️ Neurological deficit ☀️ Syncope ☀️ Unexplained shock ☀️ Features of cardiac tamponade ☀️ Acute coronary syndrome with features that don’t quite fit ⸻ ☀️ الدروس المستفادة ☑ لا تجعل shock + chest pain يساوي تلقائيًا Massive PE. ☑ ولا تجعل ST/ischaemic changes على ECG تغلق التفكير تلقائيًا عند MI. ☑ اسأل عن onset and character of pain؛ أحيانًا عشر ثوانٍ من الـ history تغيّر العلاج بالكامل. ☑ افحص pulses والضغط في الطرفين عندما يكون ذلك ممكنًا ولا يؤخر resuscitation. ☑ استخدم bedside echocardiography كجزء من التقييم السريع للمريض غير المستقر، مع العلم أن عدم وجود علامة واضحة عليه لا يستبعد dissection. ☑ Type A aortic dissection is a surgical emergency. ☑ الاشتباه في aortic dissection يغيّر تمامًا قرار antithrombotic/thrombolytic therapy. ⸻ 🎯 الرسالة الأخيرة أخطر تشخيص في الطوارئ… ليس دائمًا التشخيص الذي لم تفكر فيه. أحيانًا يكون التشخيص الذي فكرت فيه ووجدت دليلًا عليه… ثم توقفت. كان لديه myocardial infarction. وكان في cardiogenic shock. كل هذا صحيح. لكن الحقيقة الأهم كانت مختبئة خطوة واحدة للخلف: Aortic Dissection لذلك عندما تكون الصورة لا تكتمل… لا تسأل فقط: “What is happening?” اسأل أيضًا: “What caused it to happen?” لأن الإجابة الأولى قد تخبرك بما يحدث للمريض… لكن الإجابة الثانية قد تكون هي التي تنقذ حياته. Dr. Mohamed Osama

🩺 حدوته طبيه 🎬 المشهد الأول – كان جالسًا مع أولاده رجل في أوائل الستينات. لا توجد أي شكوى قبلها بدقائق. كان جالسًا مع أولاده يتحدث ويضحك بشكل طبيعي. وفجأة… وضع يده على صدره. “صدري…!” ألم شديد جدًا ظهر بصورة مفاجئة. وبعد ثوانٍ بدأ يتنفس بصعوبة. حاول أن يقف… لكنه سقط على الكرسي. وجهه شاحب. جسمه غارق في العرق. وأطرافه أصبحت باردة جدًا. تم نقله بسرعة إلى الطوارئ. ⸻ 🎬 المشهد الثاني – المريض ينهار عند وصوله: 🔴 Severe chest pain 🔴 Severe dyspnoea 🔴 Profuse sweating 🔴 Cold peripheries 🔴 Altered mental status 🔴 BP barely recordable 🔴 Severe haemodynamic instability كان واضحًا أن المريض في shock. قال أحد الأطباء: “Sudden chest pain + severe dyspnoea + shock…” ثم أكمل: “ممكن تكون Massive PE.” كان المريض ينهار أمامهم. والوقت لا يسمح بتاريخ مرضي مدته عشر دقائق. لكن… أحيانًا ثلاثة أسئلة فقط أهم من عشر تحاليل. ⸻ 🎬 المشهد الثالث – السؤال الذي غيّر اتجاه القصة اقترب الطبيب منه بينما الفريق يعمل على stabilisation. “الألم بدأ تدريجي ولا فجأة؟” قال المريض بصعوبة: “فجأة…” “مرة واحدة…” ثم سأله: “أشد ألم من أول لحظة؟” هز رأسه: “آه…” ثم جاءت الجملة الأهم: “حاسس إنه رايح لظهري.” توقف الطبيب للحظة. Sudden severe chest pain — maximal at onset — radiating to the back. هذه ليست إجابة عابرة. هذه red flag. ⸻ 🎬 المشهد الرابع – لكن الـ ECG زاد الأمر تعقيدًا تم عمل 12-lead ECG فورًا. نظر الفريق إلى الرسم. كانت هناك: Acute ischaemic ECG changes. 🔴 قال أحد الأطباء: “خلاص… Acute coronary syndrome.” الآن أصبح أمام الفريق تشخيص آخر مقنع جدًا. Chest pain. Shock. Sweating. Ischaemic ECG changes. كل شيء يدفعك نحو acute myocardial infarction. لكن الطبيب عاد إلى المريض. شيء واحد ما زال يزعجه: “لماذا الألم كان maximal from the first second؟” “ولماذا يمتد إلى الظهر؟” قرر ألا يجعل الـ ECG يمحو التاريخ المرضي. ⸻ 🎬 المشهد الخامس – الفحص الذي استغرق ثواني أمسك الطبيب النبض في اليد اليمنى. ثم اليسرى. توقف. أعاد الفحص مرة أخرى. The peripheral pulses were unequal. ثم قاس الضغط في الذراع الأخرى. كان هناك فرق واضح. الآن تغير الجو في الغرفة. قال الطبيب: “استنوا…” “ممكن الـ ECG يكون بيورينا complication… مش أصل المشكلة.” ⸻ 🎬 المشهد السادس – القطعة الناقصة تم عمل focused bedside echocardiography سريعًا أثناء استمرار resuscitation. ظهرت علامات جعلت الشك في acute aortic syndrome أعلى بكثير. المريض لم يعد مجرد رجل لديه chest pain وshock. أصبح السؤال الآن: Could this be an Acute Aortic Dissection? وبسبب عدم استقراره الشديد، تم تسريع definitive imaging / specialist assessment وفق حالته. ثم ظهرت الحقيقة. 🔴 Stanford Type A Aortic Dissection الـ dissection امتد ليؤثر على أحد coronary ostia. فحدث: Coronary malperfusion ↓ Acute myocardial infarction ↓ Severe LV dysfunction ↓ Cardiogenic shock ساد الصمت للحظات. الـ ECG لم يكن خطأ. كان المريض بالفعل لديه myocardial infarction. لكن الـ myocardial infarction لم يكن التشخيص الكامل. كان مجرد نتيجة لمرض أخطر. ⸻ 🎬 المشهد السابع – القرار الذي كان يمكن أن يغير النهاية نظر الاستشاري إلى الفريق وقال: “تخيلوا لو توقفنا عند الـ ECG.” ثم أشار إلى الشاشة: “وتخيلوا لو أعطيناه thrombolytic therapy قبل أن نفكر.” المشكلة ليست thrombus داخل coronary artery فقط. المشكلة: The wall of the aorta itself is dissecting. إعطاء thrombolysis في هذه الحالة قد يؤدي إلى catastrophic bleeding، بما في ذلك worsening haemorrhage أو tamponade، ويحوّل حالة جراحية حرجة إلى كارثة. المريض يحتاج: Immediate cardiothoracic surgical involvement وليس blind thrombolysis. ⸻ 🎬 المشهد الثامن – جلسة التعليم بعد استقرار الموقف، سأل الاستشاري المقيمين: “ما الخطأ لو قلت لكم إن التشخيص كان myocardial infarction؟” قال أحدهم: “هو فعلًا كان عنده MI.” ابتسم الاستشاري. “Exactly.” ثم كتب على السبورة: A correct diagnosis is not always the complete diagnosis. وأضاف: “المشكلة ليست دائمًا أنك أخطأت في التشخيص.” “أحيانًا المشكلة أنك وجدت تشخيصًا صحيحًا مبكرًا جدًا…” ”…فتوقفت عن البحث عن السبب.” ثم كتب: Aortic Dissection ↓ Coronary involvement ↓ Acute Myocardial Infarction ↓ Cardiogenic Shock ثم وضع دائرة حول أول سطر. “لو عالجت آخر السلسلة فقط…” “قد تقتل المريض لأنك لم ترَ أولها.” ⸻ ☀️ متى يجب أن تفكر في Aortic Dissection؟

The problem was not simply a thrombus inside a coronary artery. The problem was: The wall of the aorta itself was dissecting. Giving thrombolysis in this situation could cause catastrophic bleeding, worsen haemorrhage or precipitate cardiac tamponade, turning a critical surgical emergency into a disaster.
