𝐈𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧𝐬: 👌
Try to draw yourself the heart's surfaces, borders, and surface anatomy. 😂
Always remember 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 + fifth intercostal spaces near the lower sternal border: Tricuspid valve area (T).
3) The 2nd left intercostal space near the upper sternal border: Pulmonary valve area (P).
4) The 2nd right 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. The “coronary sulcus” is the 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 is the diaphragmatic surface of the heart.
It is the point of meeting of:
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.

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