Echocardiographic Findings

Constrictive pericarditis is a rare disease with a difficult diagnosis. Cardiac magnetic resonance (CMR) imaging data of Aga Khan University Hospital, from January 2011 to March 2020 was retrospectively reviewed and patients with the diagnosis of constrictive pericarditis were included. A total of 22 patients were included with the mean age of 46 + 16 years and majority (77%, n=17) being male. The most common findings on transthoracic echo were significant respiratory variation in mitral and tricuspid inflow velocities (91%, n=20) and septal annular e’>9 (86%, n=19). Most common finding on CMR was respiratory septal shift in 100% (n=22) followed by septal bounce in 95% (n=21), and thickened pericardium in 82% (n=18). Nearly two-third patients (n=15) were considered for pericardiectomy but it was deferred in 5 patients due to high surgical risk. Ten patients underwent pericardiectomy with no mortality on a mean follow up of 4 + 2 years. Continuous...

Myocarditis is largely underdiagnosed due to subclinical symptoms and non-availability of diagnostic techniques necessitating high index of suspicion and early disease identification. This study aimed to assess the clinical presentation, cardiac magnetic resonance (CMR) imaging findings and prognosis of these patients. After reviewing the CMR data of Aga Khan University Hospital from January 2011 to December 2019, a total of 24 patients were included with the confirmed diagnosis of myocarditis on CMR. Mean age was 33.4 +15 years with the majority (58%) being male. Dyspnea (n = 15, 62%) was the commonest symptom followed by chest pain (n = 13, 54%). On echocardiogram, 55% showed LV dysfunction. Common CMR findings were late gadolinium enhancement (n=18, 75%) and bright T2 signals (n=11, 45%).  With a mean follow-up of 3.6 + 2.0 years, one patient died of non-cardiac cause. More than half (60%) had resolution of LV dysfunction suggesting favorable prognosis. Continuous...

Objectives: The objectives of the study were to evaluate the clinical presentation, cardiac magnetic resonance (CMR) features, and outcomes of patients with dilated cardiomyopathy (DCM). Material and Methods: A retrospective study was conducted at a tertiary care center of Pakistan. All patients who underwent CMR for further evaluation of DCM during the period of 2011–2019 and in whom CMR confirmed the diagnosis of DCM, were included in the study. Patients were followed up in the year 2020 for all-cause mortality and cardiovascular hospitalizations. Results: A total of 75 patients were included in the study. The mean age was 38.7 ± 13 with the majority (n = 57, 76%) being male. Dyspnea was the most common presenting symptom (n = 68, 90.7%). The mean left ventricle ejection fraction (LVEF) by CMR was 29.3 ± 12 and mean left ventricle stroke volume (LVSV) was 66.5 ± 31. Late gadolinium enhanced (LGE) was present in 28 (37.3%) patients. Follow-up was available in 61 patients with the mean follow-up duration of 39.7 ± 27 months. Most patients (40, 65.6%) experienced all-cause major adverse cardiovascular events (MACE) during the follow-up and mortality was observed in 10 (16.4%) patients. LVSV by CMR (P = 0.03), LVEF by CMR (P = 0.02), and presence of pericardial effusion (PE) (P = 0.01) were significantly associated with all-cause MACE. On multiregression analysis, SV by CMR was associated with all cause MACE (P = 0.048). The presence of LGE was associated with higher mortality (P = 0.03). Conclusion: LVSV, LVEF by CMR, and PE were significantly associated with all-cause MACE. LGE was associated with higher mortality. Our cohort had a relatively younger age of presentation and diagnosis, and a greater mortality on follow-up, when compared with other regions of the world.

Abstract Background Hypocalcemia is a rare reversible cause of dilated cardiomyopathy in pediatric population. Myocarditis is another more frequent cause of cardiomyopathy with overlapping presenting features. Cardiac magnetic resonance imaging (CMRI) is a vital modality capable of tissue characterization for the evaluation of cardiomyopathy. The present study is the first attempt to determine if any specific characteristics on CMR exist in patients with hypocalcemic dilated cardiomyopathy. Methods A retrospective analysis of 10 cases of hypocalcemic dilated cardiomyopathy (August 2012–August 2019), among which CMRI of nine patients were analyzed. Patients were categorized in to three categories; category 1 defined as absence of edema and late gadolinium enhancement (LGE), category 2 having edema only, and category 3 with presence of both edema and LGE. A diagnosis of myocarditis was considered if both edema and LGE were present. Results The mean age of the cohort was 5.5 ± 3.3 months. The mean ejection fraction of the cohort was 20.5 ± 6.85% that improved significantly to 35.22 ± 9.3% at the time of discharge. Five of nine patients had no edema or LGE (category 1), whereas two patients each were categorized into category 2 and 3. All cases in category 1 had normalized ventricular function on follow-up. One patient in category 2 had normal ejection fraction and one was lost to follow-up. Out of the two patients in category 3, there was one mortality and another was lost to follow-up. Of the six patients at follow-up (19 ± 11.0 months), the mean left ventricle ejection fraction improved to 56.5 ± 6.1%. Conclusion Hypocalcemic dilated cardiomyopathy has a favorable outcome on rapid initiation of treatment. CMR can be utilized for further prognostication of these patients. Absence of edema and LGE predicts a good outcome, whereas presence of LGE and/or edema either indicates a worse prognosis or an underlying coexistent myocarditis warranting an early myocardial biopsy.

Introduction: Since Longo First described it in 1998, Stapled Hemorrhoidectomy has been emerging as the procedure of choice for symtomatic hemorrhoid. Several studies have shown it to be a safe, effective and relative complication free procedure. The aim of this study was to determine the suitability of (SH) as a day cas procedure at Hue University Hospital. Methods: From Decembre 2009 to April 2012, 384 patients with third- degree and fourth-degree hemorrhoids who underwent Stapled Hemorrhoidectomy were included in this study. Parameters recorded included postoperative complications, analegic requirements, duration of hospital stay and patient satisfaction. Follow-up was performed at 1 month and 3 months post-operative. Results: Of the 384 patients that underwent a Stapled Hemorrhoidectomy 252 (65,7%) were male and 132 (34,3%) were female. The mean age was 47,5 years (range 17-76 years. Duration of hospital stay: The mean day was 2,82 ± 1,15 days (range 1-6 days). There were no perioperative complications. There was one case postoperative complication: hemorrhage; Follow-up after surgery: 286 (74,4%) patients had less anal pain, 78 (20,3%) patients had moderate anal pain, 3 (0,8%) patients had urinary retention; Follow-up after one month: good for 325 (84,6%) patients, average for 59 (15,4%) patients; Follow-up after three months: good for 362 (94,3%) patients, average for 22 (5,7%) patients. Conclusion: Our present study shows that Stapled Hemorrhoidectomy is a safe, reduced postoperative pain, shorter hospital stay and a faster return to unrestricted daily activity

Abstract Background The life-threatening haemorrhagic complications of pulmonary arteriovenous malformations (PAVMs) are extremely rare, and only described in isolated cases. This study was designed to comprehensively investigate management of ruptured PAVMs. Methods We retrospectively assessed clinical and imaging data of ruptured PAVMs to summarize incidence, clinical characteristics, and outcomes following embolisation between January 2008 and January 2021. Results Eighteen of 406 (4.4%) patients with PAVMs developed haemorrhagic complications. Twelve of 18 patients were clinically diagnosed with hereditary haemorrhagic telangiectasia (HHT). Haemorrhagic complications occurred with no clear trigger in all cases. Eight of 18 patients (44.4%) were initially misdiagnosed or had undergone early ineffective treatment. 28 lesions were detected, with 89.3% of them located in peripheral lung. Computed tomography angiography (CTA) showed indirect signs to indicate ruptured PAVMs in all cases. Lower haemoglobin concentrations were associated with the diameter of afferent arteries in the ruptured lesions. Successful embolotherapy was achieved in all cases. After embolotherapy, arterial oxygen saturation improved and bleeding was controlled (P < 0.05). The mean follow-up time was 3.2 ± 2.5 years (range, 7 months to 10 years). Conclusions Life threatening haemorrhagic complications of PAVMs are rare, they usually occur without a trigger and can be easily misdiagnosed. HHT and larger size of afferent arteries are major risk factors of these complications. CTA is a useful tool for diagnosis and therapeutic guidance for ruptured PAVMs. Embolotherapy is an effective therapy for this life-threatening complication.

AbstractCone beam computed tomography (CBCT) provides multiplanar cross-sectional imaging and three-dimensional reconstructions and can be used intraoperatively in a hybrid operating room. In this study, we investigated the feasibility of using a CBCT-scanner for detecting residual stones during percutaneous nephrolithotomy (PCNL). Intraoperative CBCT-scans were made during PCNL procedures from November 2018 until March 2019 in a university hospital. At the point where the urologist would have otherwise ended the procedure, a CBCT-scan was made to image any residual fragments that could not be detected by either nephroscopy or conventional C-arm fluoroscopy. Residual fragments that were visualized on the CBCT-scan were attempted to be extracted additionally. To evaluate the effect of this additional extraction, each CBCT-scan was compared with a regular follow-up CT-scan that was made 4 weeks postoperatively. A total of 19 procedures were analyzed in this study. The mean duration of performing the CBCT-scan, including preparation and interpretation, was 8 min. Additional stone extraction, if applicable, had a mean duration of 11 min. The mean effective dose per CBCT-scan was 7.25 mSv. Additional extraction of residual fragments as imaged on the CBCT-scan occurred in nine procedures (47%). Of the follow-up CT-scans, 63% showed a stone-free status as compared to 47% of the intraoperative CBCT-scans. We conclude that the use of CBCT for the detection of residual stones in PCNL is meaningful, safe, and feasible.

Objective The aim of this study was to evaluate whether a patient with a cleft's age, associated syndrome, cleft phenotype or travel distance affects their follow-up rate. Design This study is a retrospective review of patients with CL/P treated by a craniofacial clinic. Setting The setting was a craniofacial clinic at a tertiary care university hospital. Patients, Participants Candidates were patients seen by the craniofacial clinic between January 2007 and December 2019. An initial pool of 589 patients was then reduced to 440 due to exclusion criteria. Interventions None Main Outcome Measure(s) The outcome measure was actual patient attendance to the craniofacial team compared to the team goal expectation of annual return visits. Results The mean age of participants at the end of the study was 9.0 ±  5.4 years with a mean follow-up period (total possible follow-up period length based on patient age at presentation and study window) of 5.5 ±  3.6 years. There was no association between cleft phenotype, type of syndrome, or distance to the clinic with attendance. Children with syndromes had an 11% decrease in the odds of attending follow-up visits with each 1-year increase in age compared to a 4% decrease in children without syndromes. Conclusions The only significant factors determining patient attendance were the presence of a syndrome and increasing age.
