Cardiac Structures Visualized From Within The Heart

Take a trip inside the heart !

.
.
.
🎦Here’s a great video of the cardiac structures visualized from within the heart. .
.
.
The heart is composed of 4 major valves
.
.
♦️The AV valves: Mitral and Tricuspid
.
.
🔹The Semilunar Valves: Aortic and Pulmonic .
.
.
💞The aortic valve is made up of three major cusps: the right, left, and non coronary cusps. The pulmonic valve is made up of the right, left, and anterior cusps. The mitral valve has two leaflets: the anterior and posterior leaflets. The tricuspid valve has three leaflets: the anterior, posterior, and septal leaflets. The mitral and tricuspid Valves have subvalvular apparatuses with papillary muscles and chordae. .

📝Keys about the heart valves:
.
.
🔑 they are collagenous, non conductible tissue, that form the fibrous trigone of the heart
.
.
🔑 the tricuspid valve always names the morphological right ventricle and (for the most part) is always apically displaced .
.
🔑 the mitral valve is the only AV valve that shares a continuity with a semilunar valve (the mitral- aortic supravalvular fibrosa) .
.
🔑 the pulmonic valve is the most anterior valve and aligns with the aortic right and left cusps

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s

The Pathway of Blood

Here’s a great illustration on the pathway of blood flow through the heart. It may seem easy...but you should know this cold as well as the cardiac anatomy, both of which will make procedures and understanding hemodynamics easier. . . . 💙VENOUS BLOOD- Blood flows into the heart (into the right atrium) through two major veins (the superior and inferior vena cava) as well as from the coronary sinus (cardiac venous blood from the coronaries) and then out through the first AV valve (tricuspid valve) into the right ventricle. From there blood flows into the right ventricular outflow tract, across the first semilunar valve (pulmonic valve) and into the main and then left and right pulmonary arteries. Blood then enters the lungs to become oxygenated. . . . ❤️ARTERIAL BLOOD- now that blood is oxygenated flow goes from the lungs into the left atrium through 4 veins (usually) called the pulmonary veins. From the left atrium blood flows across the other AV valve (mitral valve) and into the left

What is The Cardiac Cycle ?

The cardiac cycle refers to the sequence of events that occur and repeat with each heartbeat. It can be divided into two main stages: Systole and diastole, each of which is divided into several small steps When systole and diastole are not specified otherwise refers to ventricular contraction and relaxation Respectively, Reminder Blood flows from low to low pressure Compression increases the pressure in a Chamber, while relaxation reduces the pressure. When the AVT valves open the anterior pressures are higher than the ventricular pressures and Off when the pressure gradient is reversed. Similarly, Semiluna valves open when ventricular pressure exceeds submerged /, pulmonary pressure And stop. If the opposite is true, The cycle was started by firing shots at the SA node, which encouraged the atria to lower .
