Improved myocardial function with coronary sinus Reducer in a patient with refractory angina and heart failure with reduced ejection fraction

We report the first case providing insight on how improved perfusion might translate into improved myocardial function as assessed by cardiac magnetic resonance strain imaging, thus suggesting a physiological rationale to test CS Reducer in the setting of ischemic cardiomyopathy with reduced ejection fraction and adverse remodeling.

A 50-something woman with history of CHF of unknown etiology, and of HTN, presented for evaluation of chest pressure.Her BP was 223/125, Sp02 98% on RA. HR 106, RR 18. Here was her ED ECG:There is sinus rhythm with Left Bundle Branch Block (LBBB)There is a large amount of ST Elevation in V2 and V3 (more than 5 mm)Thus, this meets the unweighted Sgarbossa Criteria of 5 mm of discordant ST ElevationBut it does NOT meet the Smith Modified Sgarbossa Criteria, which depend on the ST/S ratio.This ratio is critical because LBBB with very large depolarization voltage (QRS) also has very large repolarization voltage (ST/T).Her...

We describe our experience of bivalirudin use, a newer direct thrombin inhibitor, in an infant who was supported with Berlin Heart EXCOR VAD (Berlin VAD) as bridge to transplant for 122 days without complications and without need for pump exchange. An 11-month-old girl with dilated cardiomyopathy with acute heart failure was awaiting cardiac transplant. Lack of improvement despite maximizing medical therapy and anticipating a prolonged waitlist time, she was supported with Berlin LVAD as a bridge to transplant. Anticoagulation with bivalirudin was started and titrated with a goal partial thromboplastin time of 60-90...

​BY JENNIFER TUONG; IVAN KHARCHENKO; JEAN LUC AGARD; &AHMED RAZIUDDIN, MDA 65-year-old man who had HIV well-controlled with highly active antiretroviral therapy, hypertension, sciatica, and restless leg syndrome presented to the emergency department with left leg pain. He also had had chemotherapy and radiation for anal cancer. The patient said the pain had started 45 minutes earlier when he was sitting on the toilet.He described the pain as sore in quality and 10/10 on the pain scale. He reported that it had started in his lower back and radiated to his left leg. He said he had had no trauma or weakness to the regio...

ConclusionRight SCA with congenital absence of the LCA is one of the rarest coronary artery anomalies. In a significant percentage of patients it is associated with ischemia and can be life-threatening. CCTA and MRI are the modalities of choice for diagnosis and risk stratification.ResumoIntroduçãoArtéria coronária única (ACU) sem cardiopatia congénita associada é uma entidade rara. Maioria dos casos é assintomática e achados acidentais, mas podem causar isquémia, insuficiência cardíaca congestiva e morte súbita (MS).Caso clíni...

We describe a rationale for concurrent BMC and left ventricular assist device therapy in selected heart failure patients. This combination therapy has demonstrated improved myocardial perfusion and cardiac function in patients with advanced ischemic cardiomyopathy. Moreover, preclinical data support improved cell retention with left ventricular unloading. The beneficial effects of BMC's are likely through a paracrine mechanism initiating a 'cardiac-repair' process. Combination therapy of BMC's and a left ventricular assist device may exhibit a synergistic effect with improved engraftment of BMC's through left ventricular u...

306Background: The use of stress-only single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) with 99mTc-labeled tracers offers improved dosimetry, imaging time, patient convenience, and departmental throughput. To date, no patient selection guidelines have been proposed for stress-only imaging. Methods: Non-attenuation corrected stress SPECT MPI results from 5960 individuals were used to derive and validate a mathematical model to predict subjects with a normal/near-normal stress-component (sum stress score

Conclusion: We conclude that elevated KB levels were beneficial for mitochondrial repair in the aging heart. However, an impaired MFN2-DRP1-mediated fusion-fission process in HF reduced this benefit, as well as Parkin degradation and mitophagic signaling cascade. Introduction The incidence of cardiovascular disease, including heart failure (HF), has increased steadily in the United States as the general population has aged (Roger et al., 2004; Savarese and Lund, 2017). Mitochondria are essential for energy generation to maintain cardiac contraction during each heartbeat. However, mitochondrial function decli...

AntunesAbstractAnomalous origin of the left coronary artery from the pulmonary artery is a rare congenital heart defect and a cause of myocardial ischemia during childhood. Most undiagnosed cases die in the first year of life as an extensive collateral network is essential for survival. The diagnosis requires a high index of clinical suspicion. The authors presen...
