Acquired intraabdominal arteriovenous fistula (AVF) is a rare disorder where the communication most commonly occurs between the abdominal aorta and inferior vena cava. Ilioiliac AVF has been reported previously, but is exceedingly rare. We present a case of acquired arteriovenous fistula of the right common iliac artery and left common iliac vein with extensive collateralization (ilioiliac AVF) in a 36-year-old female who presented with symptoms of high output congestive heart failure 18 years after sustaining an abdominal gunshot wound.

Pulmonary arterionevous malformation (PAVMs) are a rare disorder with an incidence of 2-3/1,000,000 population. Approximately 70% of cases are associated with Osler-Weber-Rendu Disease. This intrapulmonary malformation causes hypoxemia and dyspnea largely attributed to the right to left shunting.

We present a case of 25-year-old male who was admitted for fever and headaches with chronic history of epistaxis, hemoptysis, cyanosis and clubbing. Central cyanocis and clubbing were evident with hypoxemia of 65%. Heart sounds and peripheral pulses were normal. There was no systolic bruit noted in the lung bases. Multiple telangiectasias were seen in the truncal area and abdomen. Chest x-ray revealed multi-chambered cardiomegaly with no opacifications. CBC showed erythrocytosis with hematocrits of 0.68-0.78. Transthoracic echocardiography showed intact interatrial and interventricular septum, with contrast study suggestive of intrapulmonary shunting. CT angiography revealed PAVMs in bilateral lung fields. Pulmonary angiography demonstrated diffuse PAVMS in the left lung with 3 large PAVMs with multiple feeders > 7mm and smaller PAVMs in the Right lower lobe. The diagnosis was Multiple Pulmonary Arteriovenous Malformation, Osler-Weber-Rendu Disease, Brain Abscess Left Temporoparietal area. Craniotomy with brain abscess evacuation was done. Left pneumonectomy or Right lobectomy was considered but was deemed unacceptable due to high morbidity and mortality. Endovascular coil embolization was done on the 3 large fistulas on the Left lobe. Post procedure, his arterial oxygenation improved to 96%. He has no recurrence of hemoptysis, no headaches and with less episodes of shortness of breath 2 months on follow-up. Diagnosing the complex diffuse intrapulmonary malformations requires a high index of suspicion among patients with chronic cyanosis, chronic history of bleeding, and brain abscess. Treatment of this condition and its associated complications remain a big challenge and should be highly individualized.

INTRODUCTION: Patients with established atherothrombotic disease (EAD) or those with only atherothrombotic risk factors are at high risk for cardiovascular events and death. There are scant data on the clinical profile of stable Filipino patients with or at risk for atherothrombosis and their long-term outcomes. The authors'objective is to present the baseline clinical profile and four-year cardiovascular outcomes in Filipino outpatients with EAD and those with multiple atherothrombotic risk factors in comparison to the Asian and Global populations

METHODS: The Reduction of Atherothrombosis for Continued Health (REACH) registry is an international, prospective cohort of 68,236 patients aged at least 45 years old with either EAD or at least three atherothrombotic risk factors enrolled from 44 countries in 2003-2004. The Philippine cohort consists of 1040 outpatients with EAD (N=913) or at least three atherothrombotic risk factors (N=127) consecutively enrolled and followed up for at least one to four years for the occurrence of cardiovascular death (CVD), myocardial infarction (MI) and stroke.

RESULTS: Nine hundred fifty-five Filipino outpatients (96)% completed the four-year follow-up. Mean age is 65.5 years with similar sex distribution. Common risk factors included diabetes (46%), hypertension (87.4%), hypercholesterolemia (62.9%), and smoking history (29.7%). Ninety-two percent had EAD-- 43% with coronary artery disease, 45% with cerebrovascular disease (CVD) and four percent with peripheral artery disease (PAD). The combined primary endpoint of CVD/MI/stroke was 14.7%, but higher (19.8%) among those with polyvascular disease. Cerebrovascular disease (CVD) patients had the highest CVD/MI/stroke rates (17.6%); PAD patients had the highest CVD/MI/stroke and hospitalization rate (33.2%). Baseline medication usage is 81.1% for antiplatelet agents, 62.6% for statins and 69% for angiotensin-converting enzyme inhibitor/angiotensin receptor blocker but four-year follow-up medication usage rates were lower.

CONCLUSION: Filipino outpatients with or at risk for atherothrombosis experienced high long-term rates of CV events. This is the first report of long-term cardiovascular outcomes of stable Filipino outpatients with this high-risk profile.

Introduction: COVID-19 emerged as a new disease during the early period of 2020. Given that our institution is a cardiac specialty center and our patients have numerous co-morbidities compared to the general population, we wanted to determine the clinical profiles and in-hospital short-term outcomes of suspect, probable and confirmed adult COVID-19 patients seen at our institution. Methodology: We prospectively enrolled 323 adult (115 health care workers) suspect, probable and confirmed COVID- 19 patients admitted from March to June 2020. We described and analyzed their clinical presentation, and in-hospital outcomes. Results: There were 117 (36.22%) RT-PCR positive patients with 36.53% confirmed, 13.00% probable and 50.46% suspect patients. For probable and confirmed patients, 25%, 21.25%, 23.13% 16.25% had no, mild, moderate, and severe symptoms, respectively with 14.28% critical cases. Over-all mortality rate for probable and confirmed cases was 25.54% with 91.3% mortality rate for critical cases. Co-morbidities with statistically significant association with severity of disease were as follows: hypertension, heart disease, cerebrovascular disease, diabetes mellitus and COPD. Conclusion During the early period of the COVID-19 pandemic, only 36.53% of cases admitted at our institution were COVID-19 confirmed by RT-PCR. One-third of the cases were severe and critical, with more clinical instability, increased inflammatory markers, and higher in-hospital morbidity and mortality.

Objective: To quantify the extent of hyperlipidemia and its treatment in patients with stable coronary heart disease (CHD) or an acute coronary syndrome (ACS) in the Philippines. Methods: The Dyslipidemia International Study (DYSIS) II was an observational, multinational study conducted in patients aged ≥18 years with stable CHD or being hospitalized with an ACS. A full lipid profile was evaluated at baseline, and for the ACS cohort, at 4 months after discharge from hospital. Achievement of low-density lipoprotein cholesterol (LDL-C) targets and the use of lipid-lowering therapy (LLT) were assessed. Results: A total of 232 patients were enrolled from 10 centers in the Philippines, 184 with stable CHD and 48 being hospitalized with an ACS. The mean LDL-C level for the CHD patients was 88.0±40.1 mg/dL, with 33.3% achieving the target of <70 mg/dL recommended for very high-risk patients. For the ACS cohort, the mean LDL-C level was 109.0±48.5 mg/dL, with target attainment of 25.0%. The majority of the CHD cohort was being treated with LLT (97.3%), while 55.3% of the ACS patients were receiving LLT prior to hospitalization, rising to 100.0% at follow-up. There was little use of non-statins. Conclusions For these very high-risk patients from the Philippines, LDL-C target attainment was poor. Opportunities for better monitoring and treatment of these subjects are being missed.

Objectives: Adherence to clinical practice guidelines (CPG) has been shown to reduce inter-physician practice variation and improve quality of care. This study evaluated guideline adherence of physicians in two tertiary public hospitals to local CPG on COVID-19. Methods: This was a multicenter, retrospective chart review, rapid assessment method study. Guideline adherence and non-adherence (overuse and underuse) to 15 strong recommendations in the prevailing Philippine COVID-19 Living Recommendations were assessed among a sample of patients admitted in two centers from July to October 2021. Differences in adherence across COVID-19 disease severities and managing hospital units were analyzed. Results: A total of 723 patient charts from two centers were reviewed. Guideline adherence to dexamethasone use among patients with hypoxemia is 91.4% (95% CI 88.6 to 93.6) with 9.2% overuse. Tocilizumab was underused in 52.2% of patients with indications to receive the drug. There was overuse of empiric antibiotics in 43.6% of patients without suspicion of bacterial coinfection. Lowest adherence to antibiotic use was seen among patients with critical disease severity and those managed in the intensive care unit. None of the other non-recommended treatment modalities were given. Conclusion Management of COVID-19 in both centers was generally adherent to guideline recommendations. We detected high underuse of tocilizumab probably related to the global supply shortage during the study period and high overuse of antibiotics in patients without suspicion of bacterial coinfection. While the results of this study cannot be generalized in other healthcare settings, we recommend the application of similar rapid assessment studies in guideline adherence evaluation as a quality improvement tool and to identify issues with resource utilization especially during public health emergencies.
