Biventricular Pacemaker
74-year-old female presents in CHF and an echo showing reduced EF (35%) and non-compaction.
Initial CXR shows findings consistent with interstitial edema, (redistribution, fuzzy borders of the vessels and descending RPA) Kerley B lines, and left atrial enlargement.
Volume measurements showed an end diastolic volume of 217 mls, an end systolic volume of 159ccs, a stroke volume of 58ccs with a resulting ejection fraction of 26%.
Following placement of biventricular pacemaker CXR showed resolution of the heart failure, but persistence of the LAE.

Sarcoidosis and VT
57-year-old male with pathology findings consistent with granulomatous hepatitis and non-necrotizing granulomas in inguinal lymph nodes both consistent with sarcoidosis but without pulmonary findings. Lymphadenopathy is also present in the axillae and groins without involvement of the mediastinum
? Associated cardiovascular findings include findings consistent with hypertrophic cardiomyopathy with:
o Diabetes and Hypertension
o CXR showing LVE
o Abnormal stress test with concerning regions in RCA territory inferiorly
o Moderate LVH on echo with normal EF (68%) normal LA, RA PAP and RV function. LV mass was 127g/sq. m
o Focal nodular LGE in the anterior apical region in mid myocardial/subendocardial region and in the inferior mid myocardial wall medially
o Subsequently developed episodes of paroxysmal ventricular tachycardia with EP ablation and placement of a defibrillator (ICD)
o LH and RH catheterization performed 6 years after initial studies showed elevation of PC WP of 25 mmHg, mean RA pressure of 16 mmHg, mean PAP of 34 mmHg no CAD
o Subsequent CT showed mildly enlarged LA and RA with mild TR
o 6 years after initial presentation he had symptoms of biventricular failure with increasing dyspnea and pedal edema culminating in an acute episode of monomorphic VT episode, ectopic atrial flutter/fibrillation, and left bundle branch aberrancy requiring amiodarone and cardioversion. Underwent upgrade to biventricular upgrade to his ICD
