MITRAL VALVE PROLAPSE SYNDROME OR MYXOMATOUS DEGENERATION OFMITRAL VALVE. IN MITRAL VALVE PROLAPSE ONE OR BOTH MITRAL LEAFLETS ARE FLOPPY AND PROLAPSE OR BALLOON BACK INTO THE LEFT ATRIA DURING SYSTOLE WITH OR WITHOUT MITRAL REGURGITATION. MC IN YOUNG WOMEN. PRESENCE OF ATYPICAL CHEST PAIN AND MULTIPLE NON EJECTION CLICKS SUGGESTS THE DIAGNOSIS OF MVP. • THE BEST INVESTIGATION IN CASE OF MVP IS ECHOCARDIOGRAPHY. 468

CLINICAL MANIFESTATIONS OF MITRAL VALVE PROLAPSE :- • THE DIAGNOSIS OF MITRAL VALVE PROLAPSE IS MADE MOST COMMONLY BY CARDIAC AUSCULTATION IN ASYMPTOMATIC PATIENTS OR BY ECHOCARDIOGRAPHY BEING PERFORMED FOR SOME OTHER PURPOSE. • THE DIAGNOSTIC AUSCULTATORY FINDING IS MID SYSTOLIC EJECTION CLICK (NON-EJECTION CLICK). • THE PATIENTS MAY BE EVALUATED BECAUSE OF A FAMILY HISTORY OF CARDIAC DISEASE OR OCCASIONALLY MAY BE REFERRED BECAUSE OF AN ABNORMAL RESTING.

THE PRINCIPAL AUSCULTATORY FEATURE OF THIS SYNDROME IS THE MIDSYSTOLIC CLICK A HIGH PITCHED SOUND OF SHORT DURATION JUST AFTER S 1 (NON-EJECTION CLICK). THE MAJOR DIFFERENTIATING FEATURE OF THE MIDSYSTOLIC CLICK OF MVP FROM THAT DUE TO OTHER CAUSES IS THAT ITS TIMING DURING SYSTOLE MAY BE ALTERED BY MANOEUVERES THAT CHANGE HEMODYNAMIC CONDITIONS. • ANOTHER CHARACTERISTIC FINDING OF MVP IS LATE SYSTOLIC MURMUR. 472

AORTIC DISSECTION IS A CATASTROPHIC ILLNESS CHARACTERIZED BY DISSECTION OF BLOOD BETWEEN AND ALONG THE LAMINAR PLANES OF THE AORTIC MEDIA. • THIS LEADS TO FORMATION OF BLOOD FILLED CHANNELS WITHIN THE AORTIC WALL WHICH OFTEN RUPTURES OUTWARD CAUSING MASSIVE HEMORRHAGE. USUALLY THERE IS INTIMAL TEAR. BLOOD ENTERS THE AORTIC MEDIA AT THIS INTIMAL TEAR AND DISSECTS BETWEEN THE LAYERS OF SMOOTH MUSCLE IN THE MEDIA.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
