Q1095. A 65-year-old man is admitted with an extensive anterior STEMI and undergoes successful primary PCI. On the third day, he suddenly develops severe breathlessness, hypotension and pulmonary oedema. His blood pressure is 82/54 mmHg, and a new harsh pansystolic murmur with a palpable thrill is heard along the lower left sternal border. Echocardiography identifies a new ventricular septal defect with left-to-right flow.
Which right-heart catheterisation finding would most strongly support this diagnosis?
A. Giant V waves in the pulmonary capillary wedge pressure trace without a right-sided oxygen saturation step-up.
B. Equalisation of diastolic pressures in all cardiac chambers with a dip-and-plateau pattern.
C. An oxygen saturation step-up between the right atrium and right ventricle.
D. A markedly reduced pulmonary capillary wedge pressure with no intracardiac shunt.
E. A prominent right atrial pressure waveform without increased right ventricular oxygen saturation.

Q1096. A 63-year-old woman presents with two hours of central chest pain and sweating. Her pulse is 88 beats/min and blood pressure is 132/80 mmHg. The 12-lead ECG demonstrates 3 mm horizontal ST-segment depression in leads V1–V3, with tall, broad R waves and upright T waves in V2–V3. There is no ST-segment elevation in any of the 12 standard leads. These changes raise suspicion of an acute myocardial infarction that may be poorly represented on the standard ECG.

شوفوا يا جماعة الـ LAD
ينقسم Septal و Anterior
لو لقينا الـ ECG changes في
V1 - V2 = Septal
V3 - V4 = Anterior
لو لقيناه في VV1- V4
معناها Anteroseptal STEMI ونشكوا ان LAD متصكر
معناها الجزء المتضرر من القلب هو Left ventricle مع interventricluar septum
