Apical Hypertrophic Cardiomyopathy Prompting Aneurysm, Thrombus, and Cardiac Arrest in a 56-Year-Old Female.

Hypertrophic cardiomyopathy (HCM) is the most prevalent genetic cardiac disease while apical hypertrophic cardiomyopathy (apHCM) is a rare subset of HCM. The significance of this case report is to present apHCM, its chronological course, and its association with left ventricular aneurysm, thrombosis, and cardiac arrest. We present the case of a 56-year-old female with a past medical history of apHCM who was admitted for substernal chest pain, developed a ventricular storm (VT), and subsequently suffered cardiac arrest; resuscitation of spontaneous circulation (ROSC) was eventually achieved after 10 minutes. It was initially thought that her arrhythmia and hemodynamic decompensation were purely secondary to cocaine use at a party six hours prior to her presentation. During hospitalization, cardiac magnetic resonance imaging demonstrated a severe apHCM apical aneurysm, thrombosis, and a re-entrant circuit as a likely cause of this patient's decompensation and eventual cardiac arrest. After several days of hemodynamic stability and decreased dependence on intravenous antiarrhythmic medication infusions, she was extubated and transitioned to oral amiodarone and beta-blocker therapy with the implantation of a cardioverter-defibrillator (ICD). In this case, we analyze the continuum of apHCM, a rare subset of HCM once thought to be benign but with the emergence of complications, including aneurysm, thrombus formation, resistant ventricular tachycardia, and cardiac arrest. Recognition and management of apHCM with medical and/or surgical intervention are therefore critical to prevent the aforementioned sequela.

Heart failure with preserved ejection fraction update: A review of clinical trials and new therapeutic considerations.

Between 2013 and 2016 there were approximately 6.2 million adults in the United States living with heart failure; nearly half had an ejection fraction that was preserved. Despite the high prevalence of heart failure with preserved ejection fraction (HFpEF), our understanding of this disease is limited and it still carries significant morbidity and mortality worldwide. At present, physicians are burdened by the inconclusive benefits of currently available treatment options. Recently the scientific community has seen an influx of new pathophysiology studies and outcome trials that have reshaped our understanding of HFpEF as a complex, multi-systemic disease. Pharmacological trials involving beta-blockers, angiotensin II receptor antagonists, aldosterone antagonists, and angiotensin-neprilysin inhibitors have demonstrated encouraging results, but have yet to reach the significance of advancements made in the treatment of heart failure with reduced ejection fraction. This review aims to summarize landmark clinical trials that have influenced current treatment guidelines, and reports on emerging evidence supporting/refuting new treatment modalities including pharmacotherapy, lifestyle modification and device therapy.

Cardiac Tamponade Unmasking Recurrent Ovarian Cancer.

Pericardial disease is a common manifestation of malignancy. Gynecologic malignancies such as ovarian cancer rarely present with cardiac involvement. Cardiac tamponade may be the initial presentation of malignancy in as many as half of pericardial disease cases. We report the case of a 60-year-old female with known ovarian adenocarcinoma, who achieved initial success with tumor debulking and adjuvant chemotherapy but was lost to follow-up. She presented again three years later with new-onset dyspnea and described a syncopal episode. A chest radiograph showed an enlarged cardiac silhouette and bilateral pleural effusions. Transthoracic echocardiography revealed a large pericardial effusion with diastolic collapse of the right atrium and ventricle, consistent with tamponade physiology. Subxiphoid pericardiocentesis and pigtail drain were placed under fluoroscopy with resolution of symptoms and no recurrence. Neoplastic etiology was confirmed by immunocytochemistry on cell block positive for PAX-8. As an adjunct or alternative to cytologic evaluation, diffusion-weighted magnetic resonance imaging and calculation of the apparent diffusion coefficient can be used to differentiate between malignant and benign effusions. Malignant pericardial effusion in ovarian cancer is a treatable oncologic emergency where timely diagnosis and management may facilitate palliation and prolong life.

Electrocardiographic criteria for anterior STEMI - Does the cut-off point affect treatment delay?

BACKGROUND: Diagnostic criteria for anterior STEMI differ between the European Society of Cardiology (ESC) and the European Resuscitation Council (ERC). A greater degree of ST-segment elevation is required to meet ERC criteria compared to ESC criteria. This may potentially lead to discrepancies in management between emergency teams and cardiologists, subsequent delay in reperfusion therapy and worse prognosis. METHODS: We performed an observational study in patients with anterior STEMI routinely treated with primary PCI and assessed whether differing electrocardiographic diagnostic criteria could impact treatment and short-term prognosis. All patients in the study had anterior STEMI confirmed by electrocardiographic ESC criteria and subsequent coronary angiography. Patients were divided into two groups. Those who did not meet ERC criteria in the index ECG were assigned to the "non-ERC" group and were compared with those who met them - the "ERC" group. RESULTS: Out of 60 patients with anterior STEMI based on ESC criteria (mean age 66.9 ± 13.6 years, 70% males), 26 patients (44%) did not meet ERC criteria ("non-ERC" group) for STEMI. There were no significant differences in age, gender distribution or clinical characteristics between "ERC" and "non-ERC" patients. Total-Ischemic-Time, Patient-Delay, and System-Delay times were significantly longer in "non-ERC" group (433.1 ± 389.9 min vs. 264.2 ± 229.6 min, p = 0.03; 290.8 ± 337.6 min vs. 129.5 ± 144.9 min; p < 0.05 and 158.8 ± 158 vs 134.6 ± 191 min, p < 0.02 respectively). There were no differences in In-Hospital-Delay, procedure duration, and success rate of PCI. Proximal LAD occlusion (64.7%) and TIMI = 0 flow (73.5%) tended to be more frequently observed in "ERC" than in the "non-ERC" group (53.8% and 65.4%, respectively). Hospitalization time and LVEF (44.4 ± 8.7 vs 42.8 ± 9.5%, p = 0.53) were similar between groups. CONCLUSIONS: Differences in electrocardiographic criteria for anterior STEMI leave a significant proportion of patients undiagnosed. Patients with STEMI who failed to meet less strict ERC criteria had more distal LAD disease with better TIMI flow but received reperfusion therapy later. Thus, character of the disease may compensate for treatment delay but this needs to be further evaluated. Finally, lowering the cut-off point with stricter criteria compromises specificity and is expected to increase the false positive rate, however there were no false positives in this study as all patients were angiographically confirmed to have acute coronary obstruction.

Cardiac Complications Following Cardiac Surgery Procedures.

BACKGROUND: Elderly patients and those with multiple concomitant disorders are nowadays qualified for cardiac surgery procedures, which is related to higher incidence of the postoperative complications. AIM: The aim of this study was a retrospective analysis of the perioperative factors potentially contributing to occurrence of cardiac incidents after cardiac surgery procedures. METHODS: Data of 552 patients of the cardiac surgery clinic were collected and analyzed. Data concerning medical history, previous treatment, laboratory results, additional tests results, operation and hospitalization period were examined. RESULTS: In the study population of 552 patients, cardiac complications were observed in 49.5% of them. Among cardiac complications, the most frequent were supraventricular tachycardia (30.1%) and atrial fibrillation (27.4%). Postoperative bradycardia occurred in 5.25% patients, half of whom required temporary cardiac pacing. CONCLUSIONS: The risk of incidence of cardiac complications after cardiac surgery procedures depends mostly on patient's age, EuroSCORE Logistic (ESL) score, left ventricular ejection fraction, myocardial hypertrophy, presence of paroxysmal AF and coincidence of nephrological complications. The necessity of performing more than one heart defibrillation after removing aortic cross-clamp favors early postoperative bradycardia. Considering the outcomes of this study, continuing reperfusion at least until 1/3 of the aortic cross-clamp time brings no additional benefits to the patients.
