It has been shown that thrombin injection is a safe and effective technique for the treatment of iatrogenic femoral pseudoaneurysm. The aim of this study was to evaluate and compare the use of ultrasound-guided low-dose thrombin injections with ultrasonographically-guided compression repair in the treatment of iatrogenic femoral arterial pseudoaneurysm.We compared two cohorts of patients treated for iatrogenic femoral pseudoaneurysm: the first included 38 patients who underwent ultrasonographically-guided compression repair as a first-step approach between January 1998 and November 2002; the second included 21 patients treated with ultrasound-guided low-dose thrombin injection between December 2002 and December 2003.Both groups had similar demographic characteristics and aneurysm sizes (p = 0.72). Compression was successful in 24/38 patients (63%); the 14 persistent aneurysms were surgically repaired (37%). The primary thrombin injection of a mean dose of 185+/-95 U/ml (range 100-400 U/ml) successfully obliterated all of the 21 pseudoaneurysms (success rate 100 vs 63% in the compression group, p = 0.004). Thrombosis occurred within an average of 12+/-15 s of thrombin injection. Sedation was used in 42% of the patients undergoing compression and in none of those receiving thrombin (p = 0.001). The duration of hospitalization was significantly longer in patients undergoing compression therapy (9.8+/-5.6 vs 5.6+/-1.4 days, p = 0.001).Ultrasound-guided low-dose thrombin injection appears to be more effective in reducing the need for surgical repair when used to treat iatrogenic femoral pseudoaneurysm, is better tolerated by the patients, and requires a shorter hospital stay.
The advent of digital medical imaging offered unique new possibilities of analyzing, visualizing and communicating medical images. This article reviews the impact of the digital technology in the cardiac catheterization laboratory and covers a range of topics such as the standard DICOM, the transition to cineless angiography, the digital cardiac archive, the network system for imaging exchange and the role of the cardiac digital mobile imaging systems.
Endovascular methods have become more widespread and offer an alternative to surgery, which is often difficult in case of a hostile neck resulting from radiotherapy. Carotid pseudoaneurysm after laryngectomy is a very uncommon complication. We report a case of symptomatic carotid artery pseudoaneurysm treated using a stent graft.
The aim of this study was to assess the influence of coronary arteriography with the use of a non-ionic low molecular monomer (iopromide) on left ventricular function.Fifty consecutive patients with coronary artery disease (CAD) and normal left ventricular ejection fraction were studied by coronary arteriography for a stable or unstable coronary syndrome by using iopromide. They were divided into 2 groups: group 1, patients with one vessel disease; group 2, patients with multiple vessel disease. A >50% reduction of the lumen diameter by on-line quantitative angiography was considered a significant coronary stenosis. Coronary arteriography was performed by hand injection of 5 ml of iopromide avoiding the use of nitrates during the procedure. Doppler echocardiography monitoring was performed immediately before the coronary arteriography and at the end of the last coronary injection. The following parameter were recorded: E peak velocity (E) (cm/s), A peak velocity (A) (cm/s), E/A ratio, E deceleration time (EDT) (ms), isovolumic relaxation time (IRT) (ms), and left ventricular ejection fraction (EF) (%).No complications were observed during the procedures. A mean amount of 40+/-8 ml of iopromide was used. No significant variation of heart rate and arterial pressure was shown during coronary arteriography. No changes were observed either for E, A, E/A ratio or for left ventricular EF in any group of patients. A significant increase of EDT and IRT in comparison with baseline values was documented only in group 2 (from 140+/-77 to 199+/-44 and from 98+/-33 to 144+/-44, p<0.01), returning to baseline values after 10+/-3 minutes. A positive correlation was observed between EDT and IRT shift from baseline values (r=0.77; p<0.01).In conclusion, iopromide temporarily impairs left ventricular diastolic dynamics during selective coronary angiography, but only in patients with multivessel CAD.
Abstract Background To assess the interaction between heart failure (HF) severity and optimal reduction of secondary mitral regurgitation (SMR) on mortality in patients undergoing transcatheter edge-to-edge repair (M-TEER). Methods and results Among 1656 patients included in the Italian Society of Interventional Cardiology (GIse) registry Of Transcatheter treatment of mitral valve regurgitaTiOn (GIOTTO) 984 had SMR and complete data on advanced HF. Advanced HF was defined as NYHA class III or IV, left ventricular ejection fraction ≤ 30%, and > 1 HF hospitalization during the last 12 months. Optimal M-TEER was defined as residual SMR ≤ 1 + at discharge. One hundred sixteen patients (11.8%) had advanced HF. Achievement of an optimal SMR reduction was similar in patients with and without advanced HF (65% and 60% respectively). Advanced HF was an independent predictor of 2-year all-cause death (adjusted HR 1.52, 95% CI 1.09–2.10). Optimal M-TEER, as compared to a no-optimal M-TEER, was associated with a reduced risk of death both in patients with advanced (HR 0.55, 95% CI 0.32–0.97; p = 0.039) and no-advanced HF (HR 0.59, 95% CI 0.46–0.78; p < 0.001; p = 0.778 for interaction). Conclusions Advanced HF is associated with poor outcome in patients undergoing M-TEER. However, an optimal SMR reduction reduces the risk of 2-year mortality regardless of HF severity.
