Transmyocardial laser revascularization with excimer laser: clinical results at 1 year Leonard Y Lee, MD, Maureen F O’Hara, RN, Eileen B Finnin, RN, Rory Hachamovitch, MD, Massamiliano Szulc, PhD, Paul D Kligfield, MD, Peter M Okin, MD, O.Wayne Isom, MD, Todd K Rosengart, MD The Annals of Thoracic Surgery Volume 70, Issue 2, Pages 498-503 (August 2000) DOI: 10.1016/S0003-4975(00)01484-3
Fig 1 Angina class before TMR and at 1 month, 3 months, 6 months, and 12 months following TMR. Canadian Cardiovascular Angina classification based upon direct questioning of patients at the timepoints indicated. The data are represented as mean ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints (TMR = transmyocardial laser revascularization.)

Fig 2 Sublingual nitroglycerin intake per week before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. The data are represented as mean ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.) The Annals of Thoracic Surgery 2000 70, 498-503DOI: (10.1016/S0003-4975(00)01484-3)
Fig 3 Exercise tolerance testing–exercise duration before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. The data are represented as mean ± standard deviation with the base line represented as the solid square and I month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.) The Annals of Thoracic Surgery 2000 70, 498-503DOI: (10.1016/S0003-4975(00)01484-3)
Fig 4 Exercise tolerance testing ST/HR slope before therapy and at 1 month, 3 months, 6 months, and 12 months following TMR. ST/HR slope was determined from peak exercise regression of ST depression expressed as a positive value referenced to heart rate. The data are represented as means ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (ST/HR = ST segment/heart rate slope; TMR = transmyocardial laser revascularization.) The Annals of Thoracic Surgery 2000 70, 498-503DOI: (10.1016/S0003-4975(00)01484-3)
Fig 5 Myocardial viability before therapy and at 3 months, 6 months, and 12 months following TMR. Myocardial viability was assessed by 24-hour redistribution thallium nuclear medicine scan at the timepoints indicated. The data are represented as means ± standard deviation with the base line represented as the solid square and 1 month, 3 months, 6 months, and 12 months following TMR represented as open squares. ∗ p value comparing postoperational with base line timepoints. (TMR = transmyocardial laser revascularization.) The Annals of Thoracic Surgery 2000 70, 498-503DOI: (10.1016/S0003-4975(00)01484-3)
