𝐈𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧𝐬: 👌
-- Try to draw yourself the heart's surfaces, borders, and surface anatomy. 😂
-- Always remember that the site of auscultation of each valve DOES NOT correspond to its anatomical site.
-- There are 4 main areas of auscultation: ®4️⃣®
1) The 5th Lt. intercostal space medial to the midclavicular line (apex): Mitral valve area(M).
2) The 4th + 5th intercostal spaces near the lower sternal border: Tricuspid valve area (T).
3) The 2nd Lt. intercostal space near the upper sternal border: Pulmonary valve area (P).
4) The 2nd Rt. intercostal space near the upper sternal border: Aortic valve area (A).

𝐈𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭 𝐧𝐨𝐭𝐞𝐬: 🔊🎵📢🎶🎼
1. The apex is formed by the 𝒍𝒆𝒇𝒕 𝒗𝒆𝒏𝒕𝒓𝒊𝒄𝒍𝒆 while the base is formed by the𝒍𝒆𝒇𝒕 𝒂𝒕𝒓𝒊𝒖𝒎 (so the 𝒍𝒆𝒇𝒕 𝒔𝒊𝒅𝒆 of the heart forms the apex and base) 🫀

2. The four heart chambers share in the formation of the sternocostal surface.
(The main share is by the right ventricle, and the least share is by the left atrium)

3. “𝗖𝗼𝗿𝗼𝗻𝗮𝗿𝘆 𝘀𝘂𝗹𝗰𝘂𝘀” = "𝗔𝘁𝗿𝗶𝗼𝘃𝗲𝗻𝘁𝗿𝗶𝗰𝘂𝗹𝗮𝗿 𝗴𝗿𝗼𝗼𝘃𝗲".

4. The “𝙘𝙤𝙧𝙤𝙣𝙖𝙧𝙮 𝙨𝙞𝙣𝙪𝙨” is a large vein that collects most (but NOT all) venous drainage of the heart.

5. The “𝙘𝙤𝙧𝙤𝙣𝙖𝙧𝙮 𝙨𝙞𝙣𝙪𝙨” can be seen at the “base” as it lies between the back of the left atrium and the back of the left ventricle.

6. The “𝙘𝙖𝙧𝙙𝙞𝙖𝙘 𝙘𝙧𝙪𝙭”
-- It lies on the 𝘥𝘪𝘢𝘱𝘩𝘳𝘢𝘨𝘮𝘢𝘵𝘪𝘤 𝘴𝘶𝘳𝘧𝘢𝘤𝘦 of the heart.
-- It is the point of meeting:
a. Posterior interventricular groove
b. Coronary sulcus

𝐈𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭 𝐬𝐮𝐫𝐟𝐚𝐜𝐞 𝐚𝐧𝐚𝐭𝐨𝐦𝐲 𝐩𝐨𝐢𝐧𝐭: 🤏
-- The ​𝒍𝒆𝒇𝒕 𝒇𝒊𝒇𝒕𝒉 𝒊𝒏𝒕𝒆𝒓𝒄𝒐𝒔𝒕𝒂𝒍 𝒔𝒑𝒂𝒄𝒆, 3 ½ 𝒊𝒏𝒄𝒉𝒆𝒔 (9 𝒄𝒎) from the midline.
-- This point is the surface anatomy of the following anatomical structures:
𝟭. 𝗔𝗽𝗲𝘅 𝗼𝗳 𝘁𝗵𝗲 𝗵𝗲𝗮𝗿𝘁.
𝟮. 𝗙𝘂𝗻𝗱𝘂𝘀 𝗼𝗳 𝘁𝗵𝗲 𝘀𝘁𝗼𝗺𝗮𝗰𝗵.
𝟯. 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗹𝗲𝗳𝘁 𝗹𝗼𝗯𝗲 𝗼𝗳 𝘁𝗵𝗲 𝗹𝗶𝘃𝗲𝗿.

4. An aneurysm (marked dilation) of the descending thoracic aorta would most likely affect which part of the heart directly?
A. Left ventricle
B. Right ventricle
C. Left atrium
D. Right atrium

A. Left atrium
B. Left ventricle
C. Right atrium
D. Right ventricle

D. Left ventricle

9. Which heart chamber forms the right border of the heart?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
