Transverse pericardial sinus -- It could be identified by passing our finger from the right side between the superior vena cava (behind) and the ascending aorta (in front) and pushing it to the left. b. Oblique pericardial sinus -- It could be identified by passing two fingers behind the base of the heart (through the pericardial cavity). -- Both pericardial sinuses are continuous with the pericardial cavity. 𝟮. 𝗪𝗵𝗮𝘁 𝗶𝘀 𝘁𝗵𝗲 𝗱𝗼𝗺𝗶𝗻𝗮𝗻𝘁 𝗮𝗻𝗱 𝗻𝗼𝗻-𝗱𝗼𝗺𝗶𝗻𝗮𝗻𝘁 𝗰𝗼𝗿𝗼𝗻𝗮𝗿𝘆 𝗮𝗿𝘁𝗲𝗿𝘆? a. Heart “dominance” is determined by which of the initial coronary arteries supplies the posterior descending artery (PDA) (posterior interventricular artery), which, in turn, supplies the AV node. b. The right coronary artery is dominant in approximately 80% of the population. In 10% of the population, the posterior descending artery (also known as the posterior interventricular artery) arises from the left circumflex artery, rendering the right coronary artery (RCA) nondominant; the remaining 10% of the population is codominant. 𝐁𝐚𝐫𝐞 𝐚𝐫𝐞𝐚 𝐨𝐟 𝐭𝐡𝐞 𝐡𝐞𝐚𝐫𝐭: 💉 -- It lies at the medial ends of the left 4th and 5th intercostal spaces and is related to the apex of the heart. -- It shows dullness on percussion because lung tissue does not cover it (superficial cardiac dullness). -- This area is used for pericardial puncture (خرم او ثقب) (to aspirate fluid from the pericardium), as the introduced needle will not pass through pleura or lung tissue.

The patient should be continuously monitored with electrocardiography, have intravenous access, and receive supplemental oxygen. 𝐌𝐂𝐐: 💪 1. A 56-year-old patient has a stab wound in his chest. During surgical exploration, there was a penetrating wound in the right ventricle. Which of the following structures could be affected? A. SA node B. Right bundle branch C. AV bundle D. AV node 2. The bare area of the heart corresponds to which of the following sites close to the sternum? A. Right atrium B. Left 1st and 2nd intercostal space C. Right 2nd and 3rd intercostal space D. Left 3rd and 4th intercostal space E. Left 4th and 5th intercostal space 3. Clamping all arterial flow out of the heart is sometimes necessary in cardiac surgery. This could be done within the pericardial sac by inserting the index finger immediately behind the two great arteries and compressing them with the thumb of the same hand. The index finger would have to be inserted into which space? A. Cardiac notch B. Coronary sinus C. Oblique pericardial sinus D. Coronary sulcus E.
