Takotsubo cardiomyopathy associated with Kounis syndrome: A clinical case of the "ATAK complex".

A 60-year-old female developed cardiac arrest after experiencing an anaphylactic shock during administration of plasma-expanders. An electrocardiogram registered after restoration of sinus rhythm showed mild ST-elevation in the anterior precordial leads and T waves changes followed by appearance of echocardiographic alterations of left ventricular apex kinesis. Coronary angiography revealed normal coronary arteries, and cardiovascular magnetic resonance confirmed apical ballooning with late gadolinium enhancement in the segments with abnormal contractility.

Combined interventional procedure and cardiopulmonary bypass surgery in a dog with cor triatriatum dexter, patent foramen ovale, and pulmonary stenosis.

A 2-year-old American Pit Bull dog was presented for surgical evaluation of imperforate cor triatriatum dexter (CTD) and patent foramen ovale (PFO). Echocardiography identified an imperforate CTD associated with a right-to-left shunting PFO and valvular pulmonary stenosis. A 2-step interventional and surgical approach was used.

Role of Preoperative Cardiovascular Magnetic Resonance in Planning Ventricular Septal Myectomy in Patients With Obstructive Hypertrophic Cardiomyopathy.

In obstructive hypertrophic cardiomyopathy (HC), extreme heterogeneity of septal morphology makes septal myectomy particularly challenging. Although cardiovascular magnetic resonance (CMR) reconstructs ventricular anatomy with high spatial resolution, CMR is not used systematically to plan preoperatively septal myectomy. In this study, we report our results with using CMR to plan the extent of septal excision in 112 consecutive HC patients who subsequently underwent myectomy.

Electrocardiogram-gated 16-multidetector computed tomographic angiography of the coronary arteries in dogs.

The aims of this study were to assess if ECG-gated 16-multidetector CT (MDCT) provides sufficient temporal and spatial resolution to evaluate canine coronary arteries and provide a detailed description of their anatomy. A total of 24 dogs were included. Images were reviewed to assess: (1) coronary artery opacification and dominance; (2) choice of optimal R-R ECG reconstruction interval for both left coronary artery (LCA) and right coronary artery (RCA); (3) branching patterns of the left main coronary artery (LMCA); and (4) diameter and length of the LCA and RCA and classification of their branches by adapting a previously described segmental coding system.

Multislice computed tomography for the evaluation of coronary bypass grafts and native coronary arteries: comparison with traditional angiography.

Background: Multislice computed tomography (CT) is a promising new noninvasive technique for the detection of atherosclerotic disease within a vessel's wall. The present study was designed to assess the diagnostic accuracy of 64-slice CT in detecting graft disease and in the evaluation of native vessels distally to the grafts.

Methods: Forty consecutive patients with previous coronary artery bypass underwent both invasive coronary angiography and 64-slice CT.
