Value of contrast echocardiography in patient with advanced heart failure

Sažetak

Introduction: Transthoracic echocardiography is still the diagnostic standard procedure in pre heart transplant and advanced heart failure diagnostics. Despite continued improvements in non-contrast
echocardiography, image quality is sometimes suboptimal for assessing regional and segmental wall.1,2
Case report: 22-year-old patient suffering from dilative cardiomyopathy and diabetes mellitus type I presented with signs of severe dyspnoea and was admitted to intensive coronary unit due to acute heart failure. Dilative cardiomyopathy was verified with severely reduced ejection fraction to 15% of the left ventricle, with apical left ventricular thrombus, clinically NYHA IV stage, initially INTERMACS 3. The hypertrabeculation of left ventricular wall was indicating that the aetiology could be non-compaction cardiomyopathy. He was referred to our transplant centre, where complete pre-transplant work-up was conducted. Despite optimal medical therapy, clinical condition deteriorated, NT pro-BNP measured up to 13122.9-pg/mL and he was on inotropic support, heart failure medication and anticoagulation therapy due to left ventricular apical thrombus. Right heart catheterization showed a moderate increase of pressures in pulmonary circulation due to congestion and his cardiac index calculated from right heart catheter was 1.48 L/min/m2. Coronary artery disease was excluded by coronary angiogram. Due to deterioration, the patient needed ECMO support, and finally the multidisciplinary heart transplant team decided to implant extracorporeal left ventricular assist device (LVAD). As it is paramount to be aver of left ventricular thrombus in
case of LVAD implantation, the contrast echocardiography for opacification of the left ventricle (Optison GE Healthcare) was conducted
excluding the thrombus in the left ventricle and showing the extent of left ventricular trabeculation (Figure 1). Finally, patient was transplanted after three weeks of extracardiac LVAD support and was discharged from hospital in good condition. As addition, it is interesting that a patient has twin brother without diabetes mellitus, and his echocardiographic report is suggestive of dilative cardiomyopathy
–noncompaction but with far better left ventricular contractility and ejection fraction of LV of 35%.
Conclusion: Use of contrast echocardiography to guide urgent treatment decisions in critically ill patients and making treatment decisions as in device therapy provides a valuable option for improving endocardial border resolution and outcome in these patients.
