Iatrogenic acute dissection of the ascending aorta is a serious but rare complication of cardiac catheterization and percutaneous coronary intervention (PCI). Although treatment of ascending aortic dissection may require surgical repair, stenting at the origin of the dissection area may be sufficient in aortocoronary dissection (AD) following PCI. Described is the case of a 64-year-old female patient who was treated with PCI for a critical lesion of the right coronary artery (RCA). Immediate stenting at the source of the dissection was sufficient to repair the RCA lesions and successfully seal the site of retrograde propagation of the dissection...

Aortic arch pathologies such as acute aortic dissection and aneurysmal disease represent surgical challenges. Various emerging techniques and surgical prostheses have expanded the therapeutic armamentarium over the last years with one principal objective; to simplify the operation and reduce the surgical time. Besides the classic elephant trunk which has been regarded as an evolutionary leap in the treatment of extensive thoracic disease, other novel surgical approaches such as the frozen elephant trunk, the thoracic endovascular aortic repair (TEVAR) and the hybrid open branched stent grafts have been introduced...

One of the major complications of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is pulmonary vein stenosis (PVS). The natural history of PVS, especially when it involves more than one vein, leads to severe and irreversible pulmonary hypertension with end-stage right heart failure that can require, in extreme cases, even heart-lung transplantation. We report the case of a young patient who underwent RFCA for a single lasting episode of AF and developed PVS years later. He was treated with ballon venoplasty followed by stent implantation in left pulmonary vein because of PVS relief...

Behçet's Disease (BD) is a rare multi-systemic inflammatory disorder classified as a systemic vasculitis of unknown aetiology. Vascular involvement occurs in approximately 5-51.6% cases, affecting venous and arterial vessels. Cardiac involvement is rare in BD (6%). There have been published approximately 93 cases of BD associated with intracardiac thrombosis, with different treatments and courses. We present a case of a 35-year-old spanish male that, after a percutaneous pharmacomechanical thrombectomy with venous stent placement, developed high fever and extensive venous thrombosis despite anticoagulation including intracardiac thrombosis (ICT) in the right ventricle and pulmonary embolism that leaded to the diagnosis of BD...

PURPOSE OF REVIEW: Spontaneous coronary artery dissection (SCAD) is a non-iatrogenic and non-traumatic separation of the coronary arterial wall. While SCAD represents an important cause of myocardial infarction, optimal diagnostic and therapeutic options remain challenging. We sought to review recent studies and provide an update on diagnosis and management of SCAD. RECENT FINDINGS: Coronary angiography is the first-line diagnostic modality for SCAD, with three angiographic features commonly observed in SCAD: type 1 (pathognomonic angiographic appearance with contrast staining of the arterial wall), type 2 (long coronary stenosis), and type 3 (focal tubular stenosis)...

BACKGROUND: A risk classification of acute myocardial infarction (AMI) linked to a rehabilitation program has not been established. METHODS: We allocated 292 patients with AMI into the low- (L) (n=108), intermediate- (I) (n=72), and high- (H) (n=112) risk groups according to our original risk classification. The primary endpoint was major adverse cardiac events (MACE), defined as the composite of cardiac death, non-fatal AMI, stent thrombosis, and ischemia-driven target vessel revascularization...

PURPOSE: To assess the dynamic behavior of chimney grafts during the cardiac cycle. METHODS: Three chimney endovascular aneurysm repair (EVAR) stent-graft configurations (Endurant and Advanta V12, Endurant and Viabahn, and Endurant and BeGraft) were placed in silicone aneurysm models and subjected to physiologic flow. Electrocardiography (ECG)-gated contrast-enhanced computed tomography was used to visualize geometric changes during the cardiac cycle. Endograft and chimney graft surface, gutter volume, chimney graft angulation over the center lumen line, and the D-ratio (the ratio between the lengths of the major and minor axes) were independently assessed by 2 observers at 10 time points in the cardiac cycle...

A patient developed hemopericardium shortly after left brachial arterial embolectomy using an embolectomy catheter. Evaluation disclosed evolving pseudoaneurysm of the right coronary artery that was successfully managed by stenting. Misplacement of the embolectomy catheter within the coronary vessel was facilitated by an anomalous origin of the right coronary artery. This complication highlights the importance of correct insertion of the embolectomy catheter using the markers to avoid maladvancement and damage to central vessels...

BACKGROUND: Tandem stenoses of the internal carotid artery (ICA) and proximal, ipsilateral common carotid artery (CCA) or innominate artery can be treated with a hybrid approach, combining conventional carotid endarterectomy (CEA) and retrograde stenting of the proximal stenosis, through surgical exposure of the carotid bifurcation. The purpose of this study was to evaluate the results of combining eversion CEA with retrograde CCA/innominate artery stenting. MATERIAL AND METHODS: From January 2015 to July 2017, 7 patients, 6 men of a mean age of 72 years (range 59-83 years) underwent simultaneous, retrograde stenting of the proximal CCA/innominate artery and an eversion CEA of the ipsilateral ICA, through surgical exposure of the carotid bifurcation, for severe tandem stenoses...

Coronary bifurcation lesions are accounted in about 20% of all percutaneous coronary interventions and despite all-round improvements in their treatment are still perceived as complex lesion subset in interventional cardiology. Treatment of bifurcations, being technically demanding primarily due to the unique bifurcation anatomy, is related to lower procedural success rate and increased rates of long-term adverse cardiac events. According to published data, provisional approach remains a default strategy for majority of bifurcation PCI, but when perfected, two-stent bifurcation techniques can also yield good clinical outcomes...

BACKGROUND: The treatment of coronary small vessel disease (SVD) remains an unresolved issue. Drug-eluting stents (DES) have limited efficacy due to increased rates of instent-restenosis, mainly caused by late lumen loss. Drug-coated balloons (DCB) are a promising technique since native vessels remain structurally unchanged. METHODS: BASKET-SMALL 2 is a multicenter, randomized, controlled, non-inferiority trial of DCB vs. DES in native SVD for clinical endpoints...
