After the neo-aorta reconstruction, attention shifts to the neo-PA:
➡ PA sinuses + main PA are reconstructed
➡ Neo-aorta: relatively short, Neo-PA: relatively long
Coronary artery injury is not common but a possible complication in patients undergoing surgery for valve heart disease ⚠️ #echofirst
➡️ following MV surgery - 👀 postero-lateral LV wall (possible RCX lesion)
➡️ following AV surgery- 👀 inferior LV wall (possible RCA lesion)
Neo-aortic root dilatation is often not a uniform enlargement—insights from @MichaelZLZhu, @konstantinov_ie, et al in @AATSHQ:
➡ Asymmetric dilation of the entire root + non-coronary sinus prolapse
➡ Cusp malcoaptation
➡ Eccentric aortic regurgitation
Echo/CT should go beyond diameter and assess root symmetry and cusp coaptation to guide timing and a tailored repair strategy.
بلا منازع البروفسور عثمان الراضي من العباقرة الذين خرجو من ارضنا المباركة في المملكة العربية السعودية ووضعو إسم بلاد الحرمين في اعلى مراكز جراحات القلب بكندا والولايات المتحدة. عطاؤه لا ينتهي في مجتمعنا الجراحي وبالذات للقلوب الصغيرة.
بفضل الله وكرمه، حققت المركز الأول على مستوى الولايات المتحدة الامريكية في الاختبار السنوي للطب الباطني بنسبة %100 (الـ100th percentile)، من بين أكثر من ١١ ألف طبيب مقيم في الطب الباطني في السنة الاولى من مختلف الجامعات والولايات 🇺🇸
خالص الشكر لوطني وعائلتي على الدعم اللامحدود، ولـ مديرة البرنامج د. ملني على دعمها وتوجيها المستمر
For trainees: if the path of a coronary artery appears a bit too straight, it's usually intra-myocardial. Patient I operated on today with an occluded LAD, intra-myocardial Ramus, and high grade Circ. @AspiringCTS@STS_CTsurgery@StanCVFellows
Endoscopic radial artery harvesting is a fast and effective method for graft harvesting. It fits well within the concept of minimally invasive CABG.

What determines coronary artery dominance?
A) Size of the coronary artery; right-dominant in ~85% of cases
B) Artery giving rise to PDA; left-dominant in ~15% of cases
C) Artery giving rise to PDA; codominant in ~15% of cases
D) Artery giving rise to AV node; right-dominant in ~85% of cases
E) Artery giving rise to PDA; right-dominant in ~85% of cases

Pulse Oximetry
- how does a pulse oximeter work and what factors can cause it to read unreliably?
- what can the waveform tell us?
- what is the lag time with pulse oximetry & why does it matter during intubation?

Aortic root vs. ascending aorta dilation — not the same risk, not the same management.
Let’s break down key differences, follow-up strategies, and surgical thresholds. A practical guide for clinicians!
