ECG Abnormalities After Transcatheter Aortic Valve Implantation

Ibrahim Akin, Christoph A. Nienaber

Transcatheteraortic valve implantation, first introduced in 2002, has been established as an alternative modality for patients deemed not suitable for open-heart surgery. The anatomical vicinity of the atrioventricular node and the His bundle to the non-coronary and rightcoronary aortic cusps predisposes patients to conduction abnormalities in case of severe calcification or mechanical trauma during valve implantation. However, the two evaluated valves (CoreValve and Edwards SAPIEN valve) have different rates of these complications, mainly driven by their respective geometry.

Currently, there is ongoing evaluation of the true rate of conduction disorders and their clinical relevance or durability. The initial experience of fatal outcomes with conduction disorders such as complete atrioventricular block has increased the rate of subsequent pacemaker implantation up to 50%. However, prophylactic pacemaker implantation is associated with several possible complications. Thus, there is a need for further data from large-scale series taking into account the true rate of clinically relevant conduction disorders.

Conus Artery in Coronary CT Angiography

Agnieszka Mlynarska, Rafal Mlynarski, Maciej Sosnowski

Results: It was possible to visualize the conus artery in coronary CT angiography in 64 (81%) patients. The course of the conus artery in the right ventricle was commonly in the outflow tract direction. The conus artery was visualized at a distance of 33.2 ± 16.3 mm. The average diameter of the conus artery was 2.3 ± 0.8 mm. The conus artery most frequently originated from the first segment of the right coronary artery (53%) and directly from the aorta (37.9%). In the rest of the cases, there was a common trunk for both vessels (CA/RCA).

A New Sonographic Phantom for Quality Control and Training Purposes

Ahmad Bitarafan-Rajabi, Hadi Hasanzadeh, Mahdi Jahangiri, Zohreh Hoseinpour, Hamideh Nazemi, Atefeh Baghian, Moghadeseh Mahdinejad, Majid Sadeghi, Hassan Moladoust

Materials and Methods: The presented phantom consists of a two-part Plexiglas box. The larger part is filled with a mixture of ethanol (9.5 ± 0.25%) in distilled water and a solution of sodium nitrite (0.1 M) to prevent rusting. The second part is filled with a combination of 3.85% by wt. % agar, and 50 g/L of powdered graphite as the background material. In this study, chrome-plated electric guitar strings, 0.52 mm in diameter, were used. Several objects were considered as tissue-equivalent material, and their images were obtained at different times. Criteria for the selection of suitable objects comprised similarity between the obtained image and the corresponding tissues in the human body, minimal shrinkage, and change in brightness level at different times. In addition to quantitative analysis obtained from image processing, a blind qualitative study was done by a radiologist.

Is There Any Positive Remodeling after Enhanced External Counter Pulsation in Patients With Severe Refractory Angina?

Majid Kiavar, Naser Aslanabadi, Azin Alizadehasl, Ahmad Ahmadzadeh Pournaky, Arash Hashemi, Rezvanieh Salehi, Mitra Chitsazan, Sormeh Nourbakhsh, Morteza Abdar Esfahani

Patients and Methods: Thirty-two patients who had severe refractory angina despite full anti-ischemic medication and were poor candidates for invasive procedures were evaluated. After undergoing 35 sessions of EECP, the patients were followed up for 6 months for adverse events, change in quality of life, severity of the remaining symptoms according to the Canadian Cardiovascular Society (CCS) classification, and echocardiographic changes.

Results: After receiving standard EECP treatment regimen, the patients showed a marked increase in quality of life scores; a significant decrease in left ventricular (LV) end-diastolic volume index after 6 months (P = 0.045), in tandem with an increase in the LV myocardial performance index (P = 0.04) with no significant change in the LV ejection fraction; and a significant decrease in the CCS scores (P = 0.01). In addition, physical performance measures, including time to unset of angina during the exercise test, were significantly increased.
