Evaluation of myocardial perfusion and left ventricular function six months after percutaneous transmyocardial laser revascularization: Comparison of two Ho‐YAG laser systems with the same wavelength, but different energy delivery and navigation systems

Abstract

PTMR resulted in significant improvements in the clinical symptoms, but the electrical activity improved only in the Biosense DMR group, without transforming to a better LVF.

Diagnostic and prognostic value of 3D NOGA mapping in ischemic heart disease

“…33,[39][40][41][42] Brief repetitive ischemia, such as that caused by percutaneous coronary intervention (PCI), leading to temporary decrease in local wall motion (called 'stunning') can also be identified on the basis of mismatch between the voltage and LLS maps. Acquiring viability information on the catheterization table is useful to guide coronary intervention 23 and specifi cally target cell or gene injections 7,12,13,34 or intramyocardial laser therapy 35,36 to infarcted myocardium or to the infarct border zone. An increase in electromechanical discordance observed immediately after PCI indicates stunning caused by repetitive ischemia or microvascular compromise during the procedure, providing prognostic information on the outcome of the coronary intervention.…”

“…[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] The exploitation of the simultaneous recording of quantified viability and mechanical function of the infarcted area and the spatial display of the infarct border zone have led to the development of approaches for electro mechanical guidance of percutaneous intra myocardial therapies.…”
