RATIONALE: Critical care ultrasound identifies the signs of free intraperitoneal air and echogenic free fluid always indicates hollow viscus perforation (HVP) and needs immediate surgical interventions. However, in rare cases, these classic signs may also mislead proper clinical decisions. We report perforated viscus associated large peritoneal effusion with initial critical care ultrasound findings, whereas computed tomography (CT) examination confirmed a giant stomach due to superior mesenteric artery syndrome (SMAS)...

Pacemaker-lead-associated right ventricular perforation is a life-threatening complication. Acute perforation usually presents within 24 hours. Patients with lead perforation are often asymptomatic but fatal complications like hemopericardium, leading to cardiac tamponade and death, are reported. Diagnosis is based on chest x-ray, computed tomography (CT) scan, and echocardiography. The management of the lead perforation is based on clinical presentation. Extraction is avoided in cases of chronic asymptomatic lead perforations because of the associated complications...

BACKGROUND: The successful recanalization rate of chronic total occlusion (CTO) lesions without retrograde collaterals available is always low. Intravascular ultrasound (IVUS) may be useful to guide the subintimal guidewire to re-enter the true lumen. We evaluated the clinical feasibility and efficacy of the IVUS-guided wiring re-entry technique for these complex CTO lesions. METHODS: Twenty consecutive patients (19 male, mean age: 65.3 ± 12.8 years) with both failed antegrade and retrograde approaches were enrolled...

OBJECTIVE: There is limited data on the efficacy and the safety of the transradial approach (TRA) for percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), particularly in comparison with the transfemoral approach (TFA) in lesions with similar complexity. METHODS: We included 358 patients, who underwent elective CTO PCI between January 2012 and August 2017 and compared the radial (179 patients) and femoral (179 patients) approaches. The J-CTO score was similar in both groups (TRA, 2...

Cardiac perforation and intracardiac thrombosis are infrequent complications after implantable cardioverter-defibrillator (ICD) implantation, and a case of lead perforation complicated by thrombosis is extremely rare. We report the case of a 66-year-old man with delayed ICD lead perforation concomitant with intracardiac lead thrombosis successfully treated by anticoagulant therapy followed by transvenous lead management.

Background Percutaneous device closure of an ostium secundum atrial septal defect is associated with excellent outcomes and cosmetic results but at the cost of occasional serious and sometimes fatal complications as well as lifelong follow-up. Surgical intervention is required in cases of device-related complications, which carries a slightly higher risk compared to primary closure of an atrial septal defect. We present a surgical perspective of device closure of atrial septal defect. Methods Our database was searched over 4 years for complications related to percutaneous device closure of atrial septal defect, which required surgical retrieval of the device and closure of the defect...

BACKGROUND: Because of the challenges in treating calcified coronary artery disease (CAD), lesion preparation has become increasingly important prior to percutaneous coronary intervention (PCI). Despite growing data for both rotational atherectomy (RA) and orbital atherectomy (OA), there have been no multicenter studies comparing the safety and efficacy of both. We sought to examine the clinical outcomes of patients with calcified CAD who underwent atherectomy. METHODS: A total of 39 870 patients from five tertiary care hospitals who had PCI from January 2011 to January 2017 were identified...

The growth in percutaneous transluminal devices has enabled operators to tackle more complex, native, and post-bypass surgery anatomy. However, complications such as coronary artery dissection, coronary perforation, retrograde aortic dissection, arrhythmias, and acute coronary syndrome still occur with resulting mortality rates of up to 4.2% in complex interventions. Perforation of the circumflex artery is of particular interest in view of its position and relation to the surrounding cardiac structures. This is a site of potential fluid collection, and as the left atrium is fixed to the parietal pericardium at the entry of the pulmonary veins, fluid in the oblique sinus can accumulate enough pressure to compress the left atrium and the coronary sinus...

Cardiac perforation after an ICD implantation is a rare complication, with a reported incidence between 0.6-5.2%. Its manifestation might be acute, subacute, or delayed, with an acute perforation occurring within the first 24 hours after implantation, frequently accompanied by severe clinical signs, while subacute and delayed perforations have a more benign progression. Here, we report a case of a 69-year old patient with an acute right ventricular perforation by a defibrillator lead migrating all the way through the pericardium and thoracic wall into the left breast, with an unusually mild and benign clinical course, delaying prompt diagnosis and postponing subsequent surgical treatment...

BACKGROUND: Triage systems are used in emergency medical services to systematically prioritize prehospital resources according to individual patient conditions. Previous studies have shown cases of preventable deaths in emergency medical services even when triage systems are used, indicating a potential undertriage among some conditions. The aim of this study was to investigate the triage level among patients diagnosed with perforated peptic ulcer (PPU) or peptic ulcer bleeding (PUB)...

OBJECTIVES: As the number of transvenous lead extractions continues to increase, preprocedural protocols for this procedure must be assessed. The objective of this study was to determine whether an electrocardiogram (ECG)-triggered computed tomography (Et-CT) with three-dimensional (3D) reconstructions could aid lead extractors in choosing the optimal tools to improve procedural success and avoid complications. METHODS: In this study, 31 patients scheduled for transvenous lead extraction underwent a preprocedural Et-CT between January 2016 and May 2017...

PURPOSE: We describe a case of Lyme endocarditis which, to our knowledge, is the first reported case confirmed by molecular diagnostics in the United States. BACKGROUND: Valvular involvement as a manifestation of Lyme carditis is rare4 . The first case describing a possible association between Lyme disease and cardiac valvular disease in the United States was published in 19935 . Since that time, there have been 2 cases of Lyme endocarditis confirmed by Borrelia positive 16S rRNA polymerase chain reaction (PCR) and sequencing from valvular tissue8,10 and reported from Europe...

Endogenous c-Kit+ cardiac progenitor cells (eCPCs) and bone marrow (BM)-derived mesenchymal stem cells (MSCs) are being developed for cardiac regenerative therapy, but a better understanding of their physiology is needed. Here, we addressed the unknown functional role of ion-channels in freshly-isolated eCPCs and expanded BM-MSCs using patch-clamp, microfluorometry and confocal microscopy. Isolated c-Kit+ eCPCs were purified from dog hearts by immunomagnetic selection. Ion-currents were barely detectable in freshly-isolated c-Kit+ eCPCs with intracellular calcium (Ca2+ i ) buffered...

In patients with aortic regurgitation (AR), a precise preoperative assessment of aortic valve (AV) pathology is important if AV repair or sparing operation is an alternative option. The aim of this study was to assess the diagnostic accuracy of computed tomography (CT) for evaluating the AR mechanism compared with surgical inspection. 59 patients with AR who underwent AV surgery and preoperative cardiac CT were evaluated. AR mechanism was classified into type 1 (aortic dilatation or cusp perforation), type 2 (prolapsed cusp) and type 3 (cusp retraction)...

OBJECTIVES: Endomyocardial biopsy sampling is used to check acute rejection after cardiac transplant. However, it may lead to tricuspid valve injury and cardiac perforation; therefore, less invasive tools may be useful. Right heart catheterization provides valuable information about cardiac hemodynamics. Herein, we aimed to determine the correlation of right heart catheterization parameters with acute rejection and death during cardiac transplant follow-up. MATERIALS AND METHODS: We retrospectively evaluated follow-up right heart catheterization and endomyocardial biopsy results from 47 adult patients who underwent cardiac transplant at Başkent University Faculty of Medicine between 2004 and 2016...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) and dilated cardiomyopathy (DCM), despite being two dramatically different entities, have overlapping phenotypes. As it is easy to misdiagnose between ARVC and DCM, there is a need to establish a new differential diagnostic parameter to differentiate the two. We investigated the utility of endomyocardial biopsy (EMB) for the differential diagnosis, and our study had three aims. The first was to verify the EMB high diagnostic efficacy. The second was to investigate the EMB perforation risk at the right ventricle (RV) free wall of end-stage ARVC...

Cerebral aneurysms have a high mortality rate when ruptured. Endovascular techniques have improved substantially in treating this pathology. However, surgical clip ligation remains the preferred option for some aneurysms. Various techniques are used intraoperatively to assist the surgeon in dissecting the aneurysmal dome free of surrounding tissue and placing a clip around the neck safely and effectively so that no nearby perforating vessels are affected and no residual remains. These techniques include temporary clip ligation, endovascular balloon occlusion and cardiac standstill...
