- Central Venous Pressure Tracing: A-wave: RA contraction (end diastole, P-wave on ekg) C-wave: TV bows into RA (early systole) X-descent: RA relaxation(mid systole, QRS on EKG) V-Wave: RA filling (late systole, T-wave on EKG) Y-descent: early diastolic emptying RA.
- Be aggressive with treating sternal wound infections. Here’s a sternum 4 weeks post CABG that ultimately required several washouts and sternal plating followed by pec flaps for closure but we saved the bone.
- Aspiring cardiac surgeons should know the views of the mitral valve via TEE. Here’s a refresher.
- Systolic anterior motion of the mitral valve in HCM patient.
00:00 - There are 5 goals in mitral repair: 1) Preserve leaflet mobility. 2) Restore leaflet coaptation. 3) Reduce posterior leaflet height (“height" refers to the distance from the base of the leaflet at the annulus to the leaflet free margin. 4)Reduce annular dilation. 5) Prevent SAM.
- The quintessential vital sign for bypass graft patency.
00:00 - Mitral annular disjunction (MAD) is a distinct separation of the mitral annulus—LA wall continuum & the basal portion of the ventricular myocardium. MAD is detected in systole when the annulus “slides” & detaches from the myocardium by a distance ranging from 1-10mm.
- Severe constrictive pericarditis. Starting CVP was 25mmHg, CI was 1.77 L/min/m2 and PAP was 51/20. Following near total pericardiectomy CVP dropped to 10 mmHg, CI improved 3.2 L/min/m2, PAP 34/20. @KrithikaRamapr1
00:00 - 1. The RA contains: coronary sinus (CS), IVC, septum secundum 2. Appendage: large/broad base 3. Eustachian valve- IVC 4. Thebesian valve- CS 5. Crista terminalis- divides trabeculated RA from smooth RA 6. Sulcus terminalis- points to SA node 7. Pectinate- contractile muscle
- LIMA to LAD…the other graft was in situ RIMA to OM1 via the transverse sinus. Such a beautiful operation.
- Transaortic myectomy for obstructive HCM. Incise the septum at the nadir of the RCC, carry incision upward & left toward AMVL. Spongestick can rotate the apical septum into view for 2nd cut. You need to 👀base of papillary muscles when done. #cardiotwitter #MedTwitter #MedEd
00:00 - IABP Basics: Electrocardiogram tracing: - Inflates at the middle of the T wave - Deflates on the peak of the R wave. Arterial pressure waveform: - Inflates after AV closure (corresponds to dicrotic notch). - Deflates immediately prior to AV open.
