ABSTRACT
Background: It is not clear whether the latest activation sites in the left ventricle [LV] are matched with infracted regions in patients with ischemic cardiomyopathy [ICM]. We aimed to investigate whether the latest activation sites in the LV are in agreement with the region of akinesia in patients with ICM
Methods: Data were analyzed in 106 patients [age = 60.5 +/- 12.1 y, male = 88.7%] with ICM [ejection fraction 120 ms
Results: A total of 1 272 segments were studied. The latest activation sites [with longest Ts] were most frequently located in the mid-anterior [n = 32, 30.2%] and basal-anterior segments [n = 29, 27.4%], while the most common sites of akinesia were the mid-anteroseptal [n = 65, 61.3%] and mid-septal [n = 51, 48.1%] segments. Generally, no significant concordance was found between the latest activated segments and akinesia either in all the patients or in the QRS groups. Detailed analysis within the segments indicated a good agreement between akinesia and delayed activation in the basal-lateral segment solely in the patients with QRS duration
Conclusion: The akinetic segment on 2-dimensional echocardiogram was not matched with the latest activation sites in the LV determined by TDI in patients with ICM
ABSTRACT
Blunt injury to the chest can affect any one or all components of the chest wall and thoracic cavity. The clinical presentation of patients with blunt chest trauma varies widely and ranges from minor reports of pain to florid shock. Traumatic tricuspid valve regurgitation is a rare cardiovascular complication of blunt chest trauma. Tricuspid valve regurgitation is usually begotten by disorders that cause the right ventricle to enlarge. Diagnosis is made by physical examination findings and is confirmed by echocardiography. We report two cases of severe tricuspid regurgitation secondary to the rupture of the chordae tendineae of the anterior leaflet following non-penetrating chest trauma. Both patients had uneventful postoperative courses
ABSTRACT
Cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery [CABG]. However, the effect of this program on right ventricular function following CABG is unclear.The aim of this study was to evaluate the impact of cardiac rehabilitation on the right ventricular [RV] function in a cohort of patients who underwent CABG. A total of 28 patients who underwent CABG and participated consecutively in an 8-week cardiac rehabilitation program at Tehran Heart Center were studied. The control group consisted of 39 patients who refused to attend cardiac rehabilitation and only received postoperative medical treatment after registration in the Cardiac Rehabilitation Clinic. Two-dimensional and Doppler echocardiography was performed to assess the RV function in both groups at the three time points of before surgery, at the end of surgery, and at the end of the rehabilitation program. Significant increase of RV function parameters were observed in both rehabilitation group [RG] and control group [CG] at the end of the rehabilitation program compared with post-CABG evaluation in terms of tricuspid annular plane systolic execution [RG: 12.50 mm to 14.18 mm; CG: 13.41 mm to 14.56 mm], tricuspid annular peak systolic velocity [RG: 8.55 cm/s to 9.14 cm/s; CG: 9.03 cm/s to 9.26 cm/s], and tricuspid annular late diastolic velocity [RG: 8.93 cm/s to 9.39 cm/s; CG: 9.26 cm/s to 9.60 cm/s].The parameters of the RV function did improve in both groups, but this improvement was not associated with participation in the complete cardiac rehabilitation program. The R Vfunction parameters gradually improved after CABG; this progress, however, was independent of the exercise-based cardiac rehabilitation program
ABSTRACT
We report two cases of Tetralogy of Fallot with pulmonary valve bacterial endocarditis where one extended to the branch of pulmonary artery [PA]. This is a rare occurrence. Aggressive supportive care plus early and radical surgery can be life saving
