UNASSIGNED: Severe aortic valve stenosis (AS) is the most frequent valve pathology in the developed world requiring intervention. Due to common factors in pathogenesis, patients with AS frequently have concomitant coronary artery disease (CAD). Determining the relative contribution of each component to the disease state is not easy as there is much overlap in complaints. Moreover, severe AS interferes with the haemodynamic assessment of intermediate coronary lesions.
UNASSIGNED: In this case report we describe the presentation and management of an 84-year-old patient, with a severely degenerated aortic valve bioprosthesis and an intermediate coronary artery lesion, presenting with acute decompensated heart failure and chest pain. Initial invasive haemodynamic assessment of the coronary lesion provided challenging findings and a second catheterization and intervention was needed to free the patient from his chest pain.
UNASSIGNED: Optimal assessment and treatment of CAD before valve replacement are controversial. Aortic valve stenosis on itself can lead to subendocardial ischaemia with subsequent angina pectoris. Simultaneously, AS can significantly affect coronary haemodynamics, hereby interfering with intra-coronary haemodynamic assessment of co-existing coronary lesions. Currently used coronary physiological indices are not validated in the AS population and valve replacement has variable effects on the fractional flow reserve and commonly used resting indices, such as the resting full-cycle ratio. Further research on this topic is needed and an overview of currently running studies that will advance this field significantly is provided.

BACKGROUND: Coronary steal phenomenon and myocardial ischemia is a complication following decompression of a hypertensive right ventricle in patients with left coronary-cameral fistulae.
METHODS: We present a 12-year-old girl with a complex heart defect successfully operated on using a hybrid surgical-interventional approach to decompress the ventricle, embolize the fistula and reconstruct the atretic left coronary ostium.
CONCLUSIONS: A novel hybrid strategy is the best solution for coronary-cameral fistulas reliant on high ventricular pressure at high risk for coronary steal phenomenon.

BACKGROUND: The timing for heart surgery following cerebral embolization after cardiac valve vegetation is vital to postoperative recovery being uneventful, additionally Covid-19 may negatively affect the outcome. Minimally invasive methods and upgraded surgical instruments maximize the benefits of surgery also in complex cardiac revision cases with substantial perioperative risk.
METHODS: A 68 y.o. patient, 10 years after previous sternotomy for OPCAB was referred to cardiac surgery on the 10th postoperative day after neurosurgical intervention for intracerebral bleeding with suspected mitral valve endocarditis. Mitral valve vegetation, tricuspid valve insufficiency and coronary stenosis were diagnosed and treated by minimally invasive revision cardiac surgery on the 14th postoperative day after neurosurgery.
CONCLUSIONS: The present clinical case demonstrates for the first time that the minimally invasive approach via right anterior mini-thoracotomy can be safely used for concomitant complex mitral valve reconstruction, tricuspid valve repair and aorto-coronary bypass surgery, even as a revision procedure in the presence of florid endocarditis after recent neurosurgical intervention. The Covid-19 pandemic and prophylactic patient isolation slow down the efficacy of pulmonary weaning and mobilisation and prolong the need for ICU treatment, without adversely affecting long-term outcome.

BACKGROUND: Kawasaki disease is the leading cause of premature coronary artery disease in developed countries. As such, patients may require revascularisation as children. However, there are no randomized data guiding treatment so this must be individualized. This case report describes the decision-making in a young patient requiring revascularization who had already suffered stent occlusion.
METHODS: Our patient, a 16-year-old boy with Kawasaki disease, presented with cardiac arrest during exercise. Coronary angiography showed that a proximal left anterior descending artery stent implanted at the age of 8 years had occluded some time ago and his right coronary artery was also chronically occluded. He has discussed in several Heart Team meetings and with international colleagues and a consensus reached to revascularize him surgically.
CONCLUSIONS: It is vital that young patients with complex coronary disease are discussed in an extensive multidisciplinary setting to determine the most suitable means of treatment. The previously occluded stent was crucial in the individualized decision-making in this patient.

UNASSIGNED: Cardiogenic shock is the main cause of death in hospitalized patients with acute coronary syndromes, with a high mortality rate. The management of graft thrombosis after coronary artery bypass graft (CABG) surgery is challenging and the best revascularization strategy is not well defined. In patients who develop cardiac arrest due to graft thrombosis, the benefits of mechanical support during advanced cardiac life support are uncertain. Rescue extracorporeal cardiac bypass resuscitation has been used in the context of cardiopulmonary arrest, with survival rates of around 34.7% of which 28.5% with good neurological outcome.
UNASSIGNED: We present here the case of a patient who developed cardiogenic shock after CABG graft occlusion. The patient suffered refractory cardiac arrest during percutaneous revascularization and received rescue cardiopulmonary support. Revascularization was achieved and there was a successful resuscitation with the placement of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) and an Impella CP device. After a 29-day hospitalization the patient was discharged with no neurological sequelae.
UNASSIGNED: Although there is limited evidence of the benefit of a combined use of mechanical support (VA-ECMO with other mechanical devices) in the management of cardiogenic shock and cardiac arrest following CABG surgery, there seems to be a lower mortality with this approach, and possibly more favourable neurological outcomes. Further research is needed to elucidate the advantages of Impella vs. intra-aortic balloon pump combined with VA-ECMO in such patients.

Anomalous coronary artery origins appear in roughly 1% of coronary angiograms, and up to 15% of syncope and sudden cardiac death events can be attributed to anomalous coronaries. Patients with an anomalous coronary artery arising from the opposite sinus may initially present with syncope and electrocardiographic findings of ischemia.
We describe a case in which an adolescent male presented with exercise-induced angina and syncope, and his initial electrocardiogram (ECG) showed diffuse ST-segment depression with ST-segment elevation in lead aVR. Cardiac catheterization revealed there was no coronary ostium in the left coronary cusp, and the left coronary artery had an anomalous origin from the right cusp. The patient received urgent left internal mammary artery-to-left anterior descending artery coronary bypass and a saphenous vein graft to the ramus intermedius. After he underwent 6 months of medical therapy with β-blockade and angiotensin-receptor blockade, his left ventricular systolic function improved to low-normal level (left ventricular ejection fraction, approximately 50%). WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: ST-segment elevation in lead aVR is strongly prognostic for left main or triple-vessel coronary artery disease. However, in patients who present with syncope and few other coronary artery disease risk factors, this ECG finding should be suggestive of an ischemic event caused by an anomalous left coronary artery. Early recognition of this pattern of clinical signs and ECG findings by an emergency physician could be critical for making the correct diagnosis and risk stratifying the patient for early coronary angiography and urgent surgical revascularization.

Significant left main (LM) stem disease is potentially life-threatening and mandates revascularization. This study aimed to assess how patients rate the importance of particular features of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), how this determines their preference for a particular treatment strategy, and whether particular personality characteristics influence this preference.
In total, 1145 patients who visited the outpatient clinic of the Erasmus Medical Center for stable coronary artery disease were asked to complete a case vignette-questionnaire on a hypothetical significant LM stenosis amenable to PCI or CABG. To assess the individual\'s personality disposition and general distress level, each patient had to complete a set of 3 standardized, validated questionnaires with satisfactory psychometric properties. Overall 89% of patients preferred PCI to CABG. PCI was the preferred strategy despite a higher risk for repeat revascularization and need for more medication. Remarkably, the fact that a risk for repeat revascularization is more common in the PCI group is less important for the patients who opt for PCI. Risk for stroke and bleeding were the most important arguments to opt for PCI over CABG. Type D personality, depression, and anxiety were all associated with a relatively higher preference for CABG as revascularization strategy.
Overall, when given the choice patients seem to have a clear preference for PCI over CABG and consider stroke and bleeding important procedure-related complications. Patients with Type D personality, depression, or anxiety favor CABG.

To review methodological and logistical aspects of CT myocardial perfusion, current clinical evidence and possible future directions, with specific focus on use in patients with coronary artery disease (CAD).
CT myocardial perfusion imaging may be performed as an add-on to standard coronary CT angiography (CCTA), to identify regions of myocardial hypoperfusion, at rest and during adenosine stress. The principle of measurement is well-validated in animal experimental models, and CT myocardial perfusion imaging has a high degree of concordance with already clinically available perfusion imaging methods. Combining CCTA and CT myocardial perfusion imaging increases the diagnostic accuracy to identify patients with CAD associated with ischemia. In patients suspected of CAD, CCTA frequently detects coronary atherosclerotic lesions, in which revascularization could be clinically beneficial. CT myocardial perfusion imaging may be helpful to identify coronary lesions associated with myocardial ischemia, and thus potentially suitable for coronary intervention.

Ischemic mitral regurgitation (IMR) results from left ventricular remodelling after myocardial infarction and severely affects cardiovascular mortality and morbidity. Ischemic mitral valve regurgitation also represents a negative prognostic factor for long-term survival in patients undergoing surgical myocardial revascularization. While severe mitral regurgitation should always be corrected during a coronary artery bypass operation, the decision making is more difficult in patients with a moderate degree of regurgitation. In this review, we wish to highlight the negative impact of IMR on long-term survival and discuss the available evidence for surgical correction of IMR at the time of coronary revascularization.
